It is organized as a single Go module (`go.probo.inc/probo`) with a layered architecture enforced by convention rather than framework. + +The layers flow top-down: **HTTP routing** (`pkg/server`) assembles chi routers and middleware chains. **API handlers** (`pkg/server/api/*/v1`) contain GraphQL resolvers (gqlgen), MCP tool resolvers (mcpgen), and protocol handlers (SAML, OIDC, SCIM). **Business logic** (`pkg/probo`, `pkg/iam`, `pkg/trust`) validates requests and orchestrates operations. **Data access** (`pkg/coredata`) is the single location for all raw SQL -- no other package may contain SQL queries. **Infrastructure** packages provide cross-cutting capabilities: LLM integration (`pkg/llm`, `pkg/agent`), background workers (`pkg/webhook`, `pkg/mailer`, `pkg/certmanager`), and security primitives (`pkg/securecookie`, `pkg/securetoken`). + +Every feature must be exposed through all three interfaces (GraphQL, MCP, CLI) and backed by end-to-end tests in `e2e/`.

Each type implements `Error() string` and optionally `Unwrap() error`. + +| Package | Error file | Example types | +|---------|-----------|--------------| +| `pkg/iam` | `errors.go` | ErrInvalidCredentials, ErrSessionExpired, ErrAssumptionRequired | +| `pkg/iam/saml` | `errors.go` | ErrSAMLConfigurationNotFound, ErrReplayAttackDetected | +| `pkg/iam/oidc` | `errors.go` | ErrProviderNotEnabled, ErrPersonalAccountNotAllowed | +| `pkg/trust` | `errors.go` | ErrPageNotFound, ErrDocumentNotVisible | + +Callers use `errors.Is` / `errors.As` for type checks -- never string comparison. + +### GraphQL error mapping (universal -- resolver packages) + +GraphQL resolvers use `gqlutils` helper functions from `pkg/server/gqlutils/errors.go`: + +| Helper | When to use | +|--------|------------| +| `gqlutils.Internal(ctx)` | Unexpected errors (hides details from client, logs internally) | +| `gqlutils.NotFoundf(ctx, msg, ...)` | Resource not found | +| `gqlutils.Forbidden(ctx, msg)` | Authorization failure | +| `gqlutils.Unauthenticatedf(ctx, msg, ...)` | Missing/invalid authentication | +| `gqlutils.Invalidf(ctx, msg, ...)` | Validation failure | +| `gqlutils.AssumptionRequired(ctx)` | Organization session not assumed | + +Always log unexpected errors before returning `gqlutils.Internal`: + +```go +// See: pkg/server/api/console/v1/v1_resolver.go +r.logger.ErrorCtx(ctx, "cannot load vendor", log.Error(err)) +return nil, gqlutils.Internal(ctx) +``` + +### MCP panic-based authorization (module-specific -- pkg/server/api/mcp/v1) + +MCP resolvers use `MustAuthorize()` which deliberately panics on authorization failure. A `RecoveryMiddleware` catches the panic and translates `iam.ErrInsufficientPermissions` to a permission-denied MCP error. This differs from GraphQL resolvers which return errors. + +```go +// See: pkg/server/api/mcp/v1/schema.resolvers.go +r.MustAuthorize(ctx, input.ID, probo.ActionVendorUpdate) +``` + +## Data Access + +### Scoper pattern for tenant isolation (universal -- pkg/coredata) + +Every query is tenant-scoped via the `Scoper` interface. Entity structs do NOT have a `TenantID` field -- `tenant_id` is injected at query time. + +Two implementations: +- `Scope` -- adds `tenant_id = @tenant_id` WHERE clause (normal queries) +- `NoScope` -- returns `TRUE` (cross-tenant admin queries) + +**Warning:** `NoScope.GetTenantID()` panics by design.

StrictNamedArgs rejects any key present in the SQL that is not in the args map at runtime, preventing silent bugs from unset parameters. Using `pgx.NamedArgs` is an **approval blocker**. See [shared.md -- Approval blockers](../shared.md#approval-blockers-will-block-merge). + +### Static SQL fragments (universal, enforced in code review) + +`SQLFragment()` must return a static SQL string -- no conditional string building. This ensures the prepared statement shape is always the same. Use `CASE WHEN` in SQL to handle optional filters. + +Conditional string building in `SQLFragment()` is an **approval blocker**. See [shared.md -- Approval blockers](../shared.md#approval-blockers-will-block-merge). + +### Argument merging with maps.Copy (universal) + +Always use `maps.Copy` to combine args from scope, filter, and cursor.

Cursors encode as `base64url(JSON)` with `[entity_global_id, sort_field_value]`. Default page size is 25. See `pkg/page` for the shared primitives. + +### No speculative indexes (universal, enforced in code review) + +No indexes added by default in migrations. Only add when justified by observed query latency. Unique/constraint indexes are exempt. This was explicitly called out in review (PR #917). + +## Authorization + +### ABAC policy system (universal) + +The IAM system uses an AWS-like evaluation model: **explicit deny > explicit allow > implicit deny**. Action strings follow the format `service:resource:operation` (e.g., `core:vendor:create`). + +Five built-in roles: OWNER, ADMIN, VIEWER, AUDITOR, EMPLOYEE. Policies are defined in `pkg/probo/policies.go` and `pkg/iam/iam_policies.go`. + +The authorization call flow: +1. Resolver calls `r.authorize(ctx, resourceID, actionString)` +2. `AuthorizeFunc` (from `pkg/server/api/authz`) extracts identity/session from context +3. Delegates to `iam.Authorizer.Authorize` +4. Authorizer resolves membership/role, evaluates policies, records audit log on Allow + +### Resource-state access control belongs in ABAC, not UI (universal, enforced in code review) + +When a resource's state (e.g., archived) affects allowed operations, enforcement must happen in the ABAC policy system (`pkg/probo/policies.go`), not in frontend visibility toggles. Prefer Allow rules on active states over Deny rules on archived states. This was debated in PR #855 and is now an established convention. + +### AuthorizationAttributer interface (universal -- pkg/coredata) + +Resources that need authorization must implement `AuthorizationAttributes(ctx, conn) (map[string]string, error)` in their coredata entity file. This returns attributes (typically `organization_id`) used by ABAC condition evaluation. + +## Dependency Injection + +### Constructor injection (universal) + +No DI framework. All dependencies are passed as explicit constructor parameters. The pattern varies by layer: + +- **Service layer**: `NewService(ctx, pgClient, s3Client, config, ...)` with a flat `Config` struct +- **Sub-modules**: sub-services receive `*TenantService` as their single field +- **Background workers**: functional options (`With*` functions) for optional tuning knobs +- **HTTP handlers**: `NewMux(logger, svc, config, ...)` returns `*chi.Mux` + +### Functional options for optional configuration (universal) + +```go +// See: pkg/iam/scim/bridge/bridge.go +type Option func(*Bridge) + +func WithDryRun(dryRun bool) Option { + return func(s *Bridge) { + s.dryRun = dryRun + } +} +``` + +Used across: `pkg/agent` (WithTools, WithLogger, WithModel), `pkg/llm` (WithHTTPClient, WithBaseURL), `pkg/iam/scim` (WithGarbageCollectionInterval), `pkg/probo` (WithEvidenceDescriptionWorkerInterval). + +## Observability + +### Structured logging (universal) + +Framework: `go.gearno.de/kit/log` -- context-aware, typed fields, named loggers. + +```go +// See: pkg/iam/saml/gc.go +l.InfoCtx(ctx, "garbage collection completed", + log.Int64("deleted_assertions", deletedAssertions), + log.Int64("deleted_requests", deletedRequests), + log.Duration("duration", time.Since(start)), +) +``` + +**Never log PII, PHI, or sensitive data** -- log opaque identifiers (GIDs, request IDs) only.

A filter parameter that should restrict results is quietly NULL, returning all rows. + +**Why it happens:** `pgx.NamedArgs` is the more commonly known type. Developers who are new to the project reach for it by default. + +**How to avoid:** Always use `pgx.StrictNamedArgs`. It rejects any key referenced in the SQL that is not present in the args map at runtime. Declare ALL keys in every code path -- use `nil` for inactive filters. + +**Source:** Code review approval blocker (PR #845 -- "CLAUDE.md violation: pgx.NamedArgs instead of pgx.StrictNamedArgs").

See `pkg/coredata/vendor_filter.go` for the correct pattern. + +### CTE queries missing tenant_id qualification + +**What goes wrong:** When a CTE joins tables that both have `tenant_id`, the outer query's `scope.SQLFragment()` produces an unqualified `tenant_id = @tenant_id` reference, causing a runtime "ambiguous column" SQL error. + +**Why it happens:** The scope fragment is injected via `%s` and always produces `tenant_id = @tenant_id` without table qualification. This works fine for single-table queries but breaks multi-table CTEs. + +**How to avoid:** Always include the qualified `tenant_id` column (e.g., `fi.tenant_id`) in the CTE's SELECT list so the outer scope reference is unambiguous. + +**Source:** Code review bug catch (PR #845 -- "Bug: CTE missing tenant_id -- will cause runtime SQL error"). + +### Storing tenant_id on entity structs + +**What goes wrong:** Violates the Scoper invariant. The coredata convention is that entity structs have no TenantID field -- tenant isolation is enforced via the Scoper at query time. Storing it on the struct creates a source of truth conflict. + +**Why it happens:** It seems convenient to have the tenant ID on the struct for logging or passing around. One legacy entity (Vendor) has a TenantID field, which can mislead by example. + +**How to avoid:** Never add a TenantID field to new entity structs. Use `scope.GetTenantID()` at query time. See `pkg/coredata/scope.go`. + +**Source:** Documented in `pkg/coredata/CLAUDE.md`. + +### Calling NoScope.GetTenantID() + +**What goes wrong:** Panics immediately. `NoScope` is only for cross-tenant admin queries; it has no tenant ID. + +**Why it happens:** Developers use `NoScope` for admin operations that also need to insert records (which requires `GetTenantID()`). + +**How to avoid:** Only use `NoScope` for read-only cross-tenant queries. For inserts, always use a `Scope` with a specific tenant. + +**Source:** `pkg/coredata/scope.go` line 56. + +### Adding speculative database indexes + +**What goes wrong:** Unnecessary indexes slow down writes and increase storage. The team explicitly rejects premature indexes. + +**Why it happens:** Coming from other projects where indexing is standard practice for new tables. + +**How to avoid:** No indexes by default. Only add when justified by observed query latency in production. Unique/constraint indexes are exempt. + +**Source:** Code review (PR #917 -- "No index by default.

Restructure complex queries to avoid SELECT-clause subqueries. + +**Source:** Code review (PR #917 -- "Sub query in the select seams like a smell"). + +## Resolver Pitfalls + +### Using panic in GraphQL resolvers + +**What goes wrong:** Unrecovered panics crash the server. Even recovered panics produce opaque 500 errors instead of proper GraphQL error responses. + +**Why it happens:** Quick error handling shortcut, especially when copying patterns from MCP resolvers (which deliberately use MustAuthorize + panic). + +**How to avoid:** Always return errors in GraphQL resolvers. A dedicated cleanup PR (#865, 1425 lines) was merged to eliminate all instances. Exception: MCP resolvers use `MustAuthorize()` which deliberately panics, caught by `RecoveryMiddleware`. + +**Source:** Code review approval blocker (PR #865). + +### Missing authorization before service calls in resolvers + +**What goes wrong:** Data is returned or modified without access control. The resolver pattern requires authorize as the very first step. + +**Why it happens:** Easy to forget when adding a new resolver, especially for read operations that feel harmless. + +**How to avoid:** Every resolver method must call `r.authorize(ctx, resourceID, action)` as step 1. The sequence is: (1) Authorize, (2) Get service, (3) Call service, (4) Handle error. + +**Source:** Documented in `pkg/server/api/console/v1/CLAUDE.md`. + +### Using direct service calls for entities that have dataloaders + +**What goes wrong:** N+1 queries. If a resolver fetches an entity that has a dataloader via `prb.Entity.Get()` instead of `loaders.Entity.Load()`, each GraphQL field resolution triggers a separate database query. + +**Why it happens:** Direct service calls are more intuitive and work correctly -- they just perform badly. + +**How to avoid:** Check `pkg/server/api/console/v1/dataloader/dataloader.go` for the 11 entity types with batch loaders (Organization, Framework, Control, Vendor, Document, Profile, Risk, Measure, Task, File, Report). Always use the dataloader for these. + +**Source:** Codebase pattern in `pkg/server/api/console/v1/dataloader/`. + +### Editing generated files + +**What goes wrong:** All manual edits are silently overwritten next time `go generate` runs. + +**Why it happens:** The generated files (`schema/schema.go`, `types/types.go`, `server/server.go`) look like regular code and are easy to edit accidentally. + +**How to avoid:** Never edit files in `schema/` or `types/types.go`. After changing `schema.graphql`, run `go generate ./pkg/server/api/console/v1`. For MCP, edit `specification.yaml` then run `go generate ./pkg/server/api/mcp/v1`. + +**Source:** Documented in `CLAUDE.md` and all API package `CLAUDE.md` files. + +### Missing node resolver for types implementing Node + +**What goes wrong:** The GraphQL schema declares `implements Node` but the resolver has no corresponding implementation. The API surface is incomplete -- clients cannot refetch the node by ID. + +**Why it happens:** Adding the `implements Node` declaration to the schema is easy; implementing the resolver is a separate step that can be forgotten. + +**How to avoid:** Every type that implements Node must have a resolver in the `node()` query path. + +**Source:** Code review (PR #909 -- "It implements node but there is no node on the resolver."). + +## Entity Registration Pitfalls + +### Reusing a removed entity type number + +**What goes wrong:** GIDs stored in the database with the old type number will be misinterpreted as the new type, corrupting entity resolution. + +**Why it happens:** The gap in the entity type registry (`entity_type_reg.go`) looks like it should be filled. + +**How to avoid:** Removed types are tombstoned as `_ uint16 = N // EntityType - removed`. Always append new types at the end. Never fill gaps. + +**Source:** `pkg/coredata/entity_type_reg.go` lines 34, 54, 58, 70. + +### Forgetting to register a new entity in NewEntityFromID + +**What goes wrong:** The function silently returns `(nil, false)` for unregistered types. Authorization and node resolution break silently. + +**Why it happens:** Adding the const is one step; adding the switch case is a separate step in the same file. + +**How to avoid:** When adding a new entity type constant, always add the corresponding case in the `NewEntityFromID` switch in the same file. + +**Source:** `pkg/coredata/entity_type_reg.go`. + +## Authentication Middleware Pitfalls + +### Wrong middleware order + +**What goes wrong:** Authentication checks fail silently or mutual exclusion checks miss. + +**Why it happens:** The three middlewares (session, API key, identity presence) depend on a specific ordering. + +**How to avoid:** The canonical order is: `NewSessionMiddleware` -> `NewAPIKeyMiddleware` -> `NewIdentityPresenceMiddleware`. Identity presence must always be last -- it only checks context, it does not perform authentication. + +**Source:** `pkg/server/api/console/v1/resolver.go` lines 89-91. + +## Service Layer Pitfalls + +### Over-engineered service logic + +**What goes wrong:** Code review rejects the PR for unnecessary complexity. + +**Why it happens:** Developers add defensive patterns (e.g., "if updated" checks) that don't match the project's straightforward style. + +**How to avoid:** Keep service methods simple and direct. If reviewers say "useless complex logic," simplify. The team values clarity over defensive programming. + +**Source:** Code review (PR #898 -- "useless complex logic" and "We don't use this 'if updated' pattern in any other updates."). + +## Validation Pitfalls + +### Forgetting Required() on mandatory fields + +**What goes wrong:** All validators except `Required()` silently pass nil values. A mandatory field with only `SafeText()` will pass validation when nil. + +**Why it happens:** The design philosophy is "nil = optional." This is the opposite of most validation libraries. + +**How to avoid:** Always include `Required()` in the validator chain for mandatory fields. For optional fields, the nil-passing behavior is intentional. + +**Source:** Documented in `contrib/claude/validation.md` and tested in `pkg/validator/validation_test.go`. + +### Using google/uuid instead of gearno.de/crypto/uuid + +**What goes wrong:** Build may work but code review will reject it. The project explicitly bans `github.com/google/uuid`. + +**Why it happens:** `google/uuid` is the most common Go UUID library and appears first in search results. + +**How to avoid:** Always use `go.gearno.de/crypto/uuid`. For entity IDs, use `gid.New(tenantID, entityType)` instead of UUIDs. + +**Source:** Documented in `CLAUDE.md`. + +## Filter Design Pitfalls + +### Using boolean flags instead of State[] slices for multi-state filtering + +**What goes wrong:** Combinatorial flag proliferation. Adding a third state requires exponential flag combinations. + +**Why it happens:** Boolean flags seem simpler for two-state filtering. + +**How to avoid:** Use a `State[]` slice filter approach for multi-state queries. This allows flexible multi-state queries without combinatorial growth. + +**Source:** Code review (PR #855 -- "let refactor to have State[] and filter by state instead of that"). + +### Using virtual/computed columns instead of real columns + +**What goes wrong:** Virtual columns computed in SELECT are harder to maintain and don't participate in indexes. + +**Why it happens:** Feels efficient to derive a value in the query rather than adding a column. + +**How to avoid:** Prefer adding a real database column to the schema rather than computing a derived value in SELECT. + +**Source:** Code review (PR #855 -- "Let put a real column here, instead of virtual one like that"). + +## GraphQL Schema Pitfalls + +### Missing default filter on Organization query fields + +**What goes wrong:** The query returns an expensive unfiltered result set. + +**Why it happens:** Fields on Organization that accept a filter argument are added without specifying a default. + +**How to avoid:** Always provide a default filter value in the schema: `filter: SomeFilter = { snapshotId: null }`. + +**Source:** Code review (PR #845 -- "Bug: Missing default snapshot filter on 'findings' field"). + +### Audit log FK missing ON DELETE CASCADE + +**What goes wrong:** Deleting an organization fails because audit log rows still reference it. + +**Why it happens:** Default FK behavior is RESTRICT. + +**How to avoid:** Audit log tables should use `ON DELETE CASCADE` for the parent organization FK so deletion cascades automatically. + +**Source:** Code review (PR #909 -- "We want if we delete the org we don't need keep those logs."). diff --git a/.claude/guidelines/go-backend/testing.md b/.claude/guidelines/go-backend/testing.md new file mode 100644 index 000000000..2ea2295f0 --- /dev/null +++ b/.claude/guidelines/go-backend/testing.md @@ -0,0 +1,319 @@ +# Probo -- Go Backend -- Testing + +> Auto-generated by potion-skill-generator.

The Makefile declares explicit dependencies: `bin/probod` depends on `apps/console/dist/index.html` and `apps/trust/dist/index.html`. Use `SKIP_APPS=1 make build` to skip frontend compilation for backend-only work. + +## Cross-Stack Contracts + +The GraphQL schema files are the primary contract between the Go backend and TypeScript frontend. There are no Protobuf, OpenAPI, or Swagger specs. + +### GraphQL schemas (Go-authored, TypeScript-consumed) + +| Schema file | Go API package | Frontend consumer | +|---|---|---| +| `pkg/server/api/console/v1/schema.graphql` | `pkg/server/api/console/v1/` | `apps/console` (Relay "core" project) | +| `pkg/server/api/connect/v1/schema.graphql` | `pkg/server/api/connect/v1/` | `apps/console` (Relay "iam" project) | +| `pkg/server/api/trust/v1/schema.graphql` | `pkg/server/api/trust/v1/` | `apps/trust` | + +### How the contract flows + +1. A developer edits a `.graphql` schema file (Go side) +2. `go generate` regenerates the Go resolver stubs and type structs (gqlgen) +3. The developer implements resolver bodies in Go +4. `npm run relay` (Relay compiler) reads the same `.graphql` file and regenerates TypeScript types under `apps/*/src/__generated__/` +5. Frontend components consume the generated types via Relay fragments + +The Relay compiler config files (`apps/console/relay.config.json`, `apps/trust/relay.config.json`) point directly at the Go-side schema files using relative paths (e.g., `"schema": "../../pkg/server/api/trust/v1/schema.graphql"`). + +### MCP specification + +The MCP API is defined in `pkg/server/api/mcp/v1/specification.yaml` (hand-written YAML). This is consumed only by Go code generation (`mcpgen`), not by the TypeScript frontend. + +### Custom scalar type mapping + +Both stacks agree on the same custom GraphQL scalars. The Relay compiler maps them to TypeScript types: + +| GraphQL scalar | Go type | TypeScript type | +|---|---|---| +| `GID` | `gid.GID` (base64url-encoded 192-bit ID) | `string` | +| `Datetime` | `time.Time` | `string` | +| `CursorKey` | custom cursor type | `string` | +| `Duration` | `time.Duration` | `string` | +| `BigInt` | `int64` | `number` | +| `EmailAddr` | `string` (validated) | `string` | + +### GID (Global ID) format + +Every entity in the system is identified by a `gid.GID` -- a 192-bit value encoding tenant ID (8 bytes), entity type (2 bytes), timestamp (8 bytes), and random uniqueness (6 bytes). Serialized as base64url (no padding) across all boundaries: database, GraphQL, JSON, and CLI. Defined in `pkg/gid/gid.go`. Entity type constants registered in `pkg/coredata/entity_type_reg.go` -- removed types are tombstoned with blank identifiers and must never be reused. + +### GraphQL error code contract + +The Go backend returns GraphQL errors with `extensions.code` values. The TypeScript `@probo/relay` package (`packages/relay/src/errors.ts`) maps these codes to typed error classes that frontend error boundaries catch: + +- `UNAUTHENTICATED` -> `UnAuthenticatedError` +- `FORBIDDEN` -> `ForbiddenError` +- `INTERNAL_SERVER_ERROR` -> `InternalServerError` +- `ASSUMPTION_REQUIRED` -> `AssumptionRequiredError` +- `NDA_SIGNATURE_REQUIRED` -> `NDASignatureRequiredError` +- `FULL_NAME_REQUIRED` -> `FullNameRequiredError` + +### Three-interface API surface rule + +Every feature must be exposed through all three interfaces and kept in sync: + +1. **GraphQL** -- `pkg/server/api/console/v1/schema.graphql` (+ codegen) +2. **MCP** -- `pkg/server/api/mcp/v1/specification.yaml` (+ codegen) +3. **CLI** -- `pkg/cmd/` + +If you add a mutation in GraphQL, add the corresponding MCP tool and CLI command. If you rename or change a type, update it everywhere. Every new Go API endpoint must have end-to-end tests in `e2e/`. + +## Deployment + +### Infrastructure + +- **Database**: PostgreSQL 18.1 +- **Object storage**: SeaweedFS (S3-compatible) +- **Docker image**: `ghcr.io/getprobo/probo` (multi-arch, published on tag push) +- **Binaries**: `probod`, `prb`, `probod-bootstrap` (built by GoReleaser) + +### Local development stack + +`compose.yaml` at the repository root defines the local development infrastructure: + +| Service | Purpose | Port | +|---|---|---| +| `postgres` | Primary database | 5432 | +| `seaweedfs` | S3-compatible object storage | 8333 | +| `grafana` | Dashboards | 3001 | +| `prometheus` | Metrics collection | 9191 | +| `loki` | Log aggregation | 3100 | +| `tempo` | Distributed tracing (OTLP) | 4317 | +| `mailpit` | Email testing (SMTP + web UI) | 1025/8025 | +| `chrome` | Headless browser (PDF generation) | 9222 | +| `pebble` | ACME testing (Let's Encrypt simulator) | 14000 | +| `keycloak` | OIDC/SAML identity provider for testing | 8082 | + +Start with `make stack-up`, stop with `make stack-down`. + +### Sandbox development + +For full-stack development and e2e testing, a Lima VM sandbox is available via `contrib/lima/sandbox.sh`. Commands: `make sandbox-create`, `make sandbox-start`, `make sandbox-stop`, `make sandbox-delete`, `make sandbox-ssh`. Code changes are reflected immediately via virtiofs mount.

The admin console (`apps/console`) and the public trust center (`apps/trust`) both use Relay 19 as their GraphQL client, React Router v7 for client-side routing with data loaders, and Tailwind CSS v4 for styling. They communicate with the Go backend through GraphQL schemas that serve as the cross-stack contract (see [shared.md -- Cross-Stack Contracts](../shared.md#cross-stack-contracts) for details). + +Both apps follow a feature-slice architecture where route files define the page tree, pages contain colocated Relay queries and fragments, and shared UI primitives live in `@probo/ui`. The Relay compiler reads the Go-authored `.graphql` schema files directly and generates TypeScript types into `__generated__/` directories -- there are no hand-written API types on the frontend. The compiled frontend assets are embedded into the Go binary (`bin/probod`), so `make build` must compile both apps before the Go build step. + +A set of shared packages (`packages/*`) provides the design system (`@probo/ui`), the Relay network layer (`@probo/relay`), domain helpers (`@probo/helpers`), shared hooks (`@probo/hooks`), routing utilities (`@probo/routes`), i18n (`@probo/i18n`), and ESLint configuration (`@probo/eslint-config`). Two additional packages serve specialized roles: `packages/emails` provides React Email templates compiled to Go template HTML, and `packages/n8n-node` is an n8n community node for the Probo API. + +## Module Map + +| Module | Package Name | Purpose | Key Patterns | +|--------|-------------|---------|--------------| +| `apps/console` | `@probo/console` | Admin dashboard SPA (port 5173) | Two Relay environments (core + IAM), feature-slice routes, snapshot mode, permission fragments, Loader component pattern | +| `apps/trust` | `@probo/trust` | Public trust center SPA (port 5174) | Single Relay environment, path-prefix routing, auth redirects with continue URLs, NDA signing flow | +| `packages/ui` | `@probo/ui` | Shared design system | Tailwind Variants (`tv()`), Radix primitives, Atom/Molecule/Layout hierarchy, Storybook 10 | +| `packages/relay` | `@probo/relay` | Relay FetchFunction factory + typed error classes | `makeFetchQuery`, typed GraphQL error-to-exception mapping | +| `packages/helpers` | `@probo/helpers` | Domain formatters, enum labels/variants, utilities | Translator injection pattern, `as const` enum arrays, `getXLabel`/`getXVariant` | +| `packages/hooks` | `@probo/hooks` | Shared React hooks | `useToggle`, `useList`, `usePageTitle`, `useCopy`, `useSystemTheme` | +| `packages/emails` | `@probo/emails` | React Email templates for transactional emails | TSX with Go template placeholders, build to `.html.tmpl`, embedded in Go binary | +| `packages/n8n-node` | `@probo/n8n-nodes-probo` | n8n community node for Probo API | Resource/Operation slices, inline GraphQL, cursor pagination | + +## Canonical Examples + +| File | What it demonstrates | +|------|---------------------| +| `apps/console/src/routes/documentsRoutes.ts` | New-style route definitions using Loader components (no `withQueryRef`), nested tab routes, lazy loading | +| `apps/console/src/pages/organizations/documents/DocumentsPageLoader.tsx` | Canonical Loader component: `useQueryLoader` + `useEffect` + Suspense + CoreRelayProvider | +| `apps/trust/src/pages/DocumentPage.tsx` | Full page with colocated queries/mutations, typed error handling, `__typename` dispatch, `getPathPrefix()` usage | +| `packages/ui/src/Atoms/Badge/Badge.tsx` | Canonical UI atom: `tv()` variant factory, `asChild`/`Slot`, typed props, named export | +| `packages/helpers/src/audits.ts` | Standard domain helper: `as const` enum array, `getXLabel` with Translator, `getXVariant` for badge variants | + +## Topic Index + +- [Patterns](./patterns.md) -- Relay data fetching, routing, component architecture, forms, error handling +- [Conventions](./conventions.md) -- TypeScript style, imports, naming, project structure +- [Testing](./testing.md) -- Storybook, vitest, e2e testing approach +- [Pitfalls](./pitfalls.md) -- common mistakes, deprecated patterns, things that break silently +- Module-specific notes: + - [apps/console](./module-notes/apps-console.md) -- dual Relay environments, snapshot mode, permission checks + - [apps/trust](./module-notes/apps-trust.md) -- path-prefix routing, auth flows, NDA signing + - [packages/emails](./module-notes/packages-emails.md) -- React Email + Go template hybrid + - [packages/n8n-node](./module-notes/packages-n8n-node.md) -- n8n community node conventions + + +## Team Notes + +_Reserved for manual additions by the team -- this section is preserved on refresh._ + + + +## Open Questions + +1.

There are no separate `.graphql` files on the frontend. + +```tsx +// Example from apps/trust/src/pages/DocumentPage.tsx +export const documentPageQuery = graphql` + query DocumentPageQuery($id: ID!) { + node(id: $id) @required(action: THROW) { + __typename + ... on Document { + id + title + isUserAuthorized + } + } + } +`; +``` + +The `hooks/graph/` directory in `apps/console` is **legacy** -- new code must colocate operations in the consuming component. This is enforced by the `relay/must-colocate-fragment-spreads` ESLint rule. + +### Fragment-Based Data Requirements (universal) + +Components declare their data needs via Relay fragments. Fragment names must match the component name: + +```tsx +// Example pattern from contrib/claude/relay.md +const contactFragment = graphql` + fragment VendorContactsTabFragment_contact on VendorContact { + id + fullName + email + canUpdate: permission(action: "core:vendor-contact:update") + canDelete: permission(action: "core:vendor-contact:delete") + } +`; +``` + +Never create custom TypeScript types for API data. All data shape types come from Relay-generated fragment types in `__generated__/` directories. This is enforced by a custom ESLint plugin (`@probo/eslint-plugin-relay-types`). + +### Route-Level Data Loading (universal) + +Both apps preload data in React Router loaders before rendering. There are two patterns, and the codebase is migrating from the older one to the newer one: + +**New pattern (preferred): Loader component** + +The route definition lazily imports a `*Loader` component that handles query loading internally: + +```tsx +// From apps/console/src/routes/documentsRoutes.ts +{ + path: "documents", + Fallback: PageSkeleton, + Component: lazy(() => import("#/pages/organizations/documents/DocumentsPageLoader")), +} +``` + +The Loader component uses `useQueryLoader` + `useEffect`: + +```tsx +// From apps/console/src/pages/organizations/documents/DocumentsPageLoader.tsx +function DocumentsPageQueryLoader() { + const organizationId = useOrganizationId(); + const [queryRef, loadQuery] = useQueryLoader(documentsPageQuery); + + useEffect(() => { + if (!queryRef) { + loadQuery({ organizationId }); + } + }); + + if (!queryRef) return ; + return ; +} +``` + +**Old pattern (deprecated): `withQueryRef` HOC** (enforced in code review) + +```tsx +// From apps/console/src/routes/assetRoutes.ts -- DEPRECATED, do not use in new code +loader: loaderFromQueryLoader(({ organizationId }) => + loadQuery(coreEnvironment, assetsQuery, { + organizationId, + snapshotId: null, + }), +), +Component: withQueryRef( + lazy(() => import("#/pages/organizations/assets/AssetsPage")), +), +``` + +Code reviewers will block PRs that use `withQueryRef` -- use a Loader component instead. + +### Mutations (universal) + +Use `useMutation` from `react-relay` combined with `useToast` from `@probo/ui` for user feedback: + +```tsx +// Pattern from contrib/claude/relay.md +const { toast } = useToast(); +const [createObligation, isCreating] = useMutation(createMutation); + +const onSubmit = (formData: FormData) => { + createObligation({ + variables: { input: { ...formData }, connections: [connectionId] }, + onCompleted() { + toast({ title: __("Success"), description: __("Created"), variant: "success" }); + }, + onError(error) { + toast({ + title: __("Error"), + description: formatError(__("Failed"), error as GraphQLError), + variant: "error", + }); + }, + }); +}; +``` + +**Deprecated hooks -- do not use:** +- `useMutationWithToasts` -- use `useMutation` + `useToast` instead (enforced in code review) +- `promisifyMutation` -- use `useMutation` with `onCompleted`/`onError` callbacks + +### Relay Store Updates (universal) + +Use Relay directives for connection updates -- no manual store manipulation: + +- `@prependEdge(connections: $connections)` -- add to beginning of list +- `@appendEdge(connections: $connections)` -- add to end of list +- `@deleteEdge(connections: $connections)` -- remove from list +- Fragment spread on update mutations -- Relay auto-updates in place + +The `connections` variable comes from the `__id` field on the connection in the parent fragment. Use `ConnectionHandler.getConnectionID()` with matching filter args. + +### Destructive Actions (universal) + +Destructive mutations (delete) must be wrapped with `useConfirm` for a confirmation dialog before execution. + +### Pagination (universal) + +Cursor-based pagination uses `usePaginationFragment` with `@connection` directive. `SortableTable` from `apps/console/src/components/SortableTable.tsx` is the standard component for rendering paginated, sortable lists. + +## Routing + +### Route Definitions (universal) + +Routes are defined as arrays that satisfy `AppRoute[]` from `@probo/routes`. Each app assembles its routes differently: + +- **Console**: feature-specific route files in `src/routes/*.ts` (e.g., `riskRoutes.ts`, `assetRoutes.ts`), assembled in `src/routes.tsx` +- **Trust**: all routes defined in `src/routes.tsx` with `createBrowserRouter` + +All route arrays end with `satisfies AppRoute[]` for type safety. + +### Lazy Loading (universal) + +Page components are code-split using `lazy()` from `@probo/react-lazy`: + +```tsx +Component: lazy(() => import("#/pages/organizations/assets/AssetsPage")), +``` + +Pages use default exports (required by `React.lazy`). All other modules use named exports. + +### Error Boundaries (universal) + +Both apps use React Router `ErrorBoundary` components per route group: + +- **Console**: `RootErrorBoundary` at root, `OrganizationErrorBoundary` per organization scope +- **Trust**: `RootErrorBoundary` on every content route, `DocumentPageErrorBoundary` for document pages + +Error boundaries catch typed errors from `@probo/relay` and redirect accordingly: +- `UnAuthenticatedError` -- redirect to login +- `AssumptionRequiredError` -- redirect to organization assume page (console) +- `FullNameRequiredError` -- redirect to full-name page (trust) +- `NDASignatureRequiredError` -- redirect to NDA page (trust) + +See `apps/console/src/components/OrganizationErrorBoundary.tsx` and `apps/trust/src/components/RootErrorBoundary.tsx`. + +## Component Architecture + +### Design System Hierarchy (module-specific: packages/ui) + +`@probo/ui` follows an Atom/Molecule/Layout hierarchy: + +| Layer | Location | Examples | +|-------|----------|----------| +| Atoms | `packages/ui/src/Atoms/` | Button, Badge, Checkbox, Icons, Tabs, Spinner | +| Molecules | `packages/ui/src/Molecules/` | Dialog, EditableRow, RisksChart, Combobox | +| Layouts | `packages/ui/src/Layouts/` | Layout, CenteredLayout, ErrorLayout | + +Variant logic uses `tailwind-variants` (`tv()`) -- not `cn()` -- for components with variant props. See `packages/ui/src/Atoms/Badge/Badge.tsx` for the canonical atom pattern. + +### asChild / Slot Pattern (module-specific: packages/ui) + +Components accepting `asChild` delegate rendering to the child element via a local `Slot` component (`packages/ui/src/Atoms/Slot.tsx`), similar to Radix Slot. Always pass exactly one child when using `asChild`. + +### Radix UI Primitives (module-specific: packages/ui) + +Accessible headless primitives come from `@radix-ui/*` packages (Dialog, Dropdown, Popover, Select, Tabs, Label, ScrollArea). Never build these from scratch. + +## Forms + +### Validation (universal across apps) + +Forms use `react-hook-form` + `zod` schemas via the `useFormWithSchema` wrapper hook: + +```tsx +const form = useFormWithSchema(schema, { defaultValues }); +``` + +Zod schemas are the single source of truth for form data types -- use `z.infer` for type derivation. + +### Domain Helpers for Form Options (universal) + +`@probo/helpers` provides `getXOptions(__)` functions that map enum arrays to `{ value, label }[]` arrays ready for select/dropdown components. The `Translator` function (`__` from `useTranslate()`) is always the first argument. + +## Permission Checks (module-specific: apps/console) + +Permissions are fetched inline inside Relay fragments using the `permission(action:)` field: + +```graphql +canCreate: permission(action: "core:asset:create") +canUpdate: permission(action: "core:asset:update") +canDelete: permission(action: "core:asset:delete") +``` + +Components gate UI controls (edit buttons, delete actions) on these boolean fields from fragment data. There are no separate permission hooks. + +See [shared.md -- Review-Enforced Standards](../shared.md#review-enforced-standards) for the broader rule that access control belongs in ABAC policies, not UI conditionals. + +## Snapshot Mode (module-specific: apps/console) + +Most list and detail pages support a read-only snapshot mode activated by a `:snapshotId` route parameter. Pages check `Boolean(snapshotId)` to hide edit/delete controls and adjust breadcrumbs/URLs to use the `/snapshots/:snapshotId/...` prefix. Route files define duplicate routes for both normal and snapshot paths. + +See `apps/console/src/pages/organizations/risks/RiskDetailPage.tsx` for the correct pattern. + +## Error Handling + +### Relay Network Layer (universal) + +`@probo/relay` (`packages/relay/src/fetch.ts`) maps GraphQL error extension codes to typed JavaScript error classes. HTTP 500 throws `InternalServerError`. Only the first matching error code is thrown -- subsequent errors in the same response are ignored. + +See [shared.md -- GraphQL error code contract](../shared.md#cross-stack-contracts) for the full code-to-class mapping. + +### Mutation Error Handling (universal) + +Mutations handle errors in two callbacks: +- `onCompleted` -- for GraphQL-layer errors returned in `response.errors[]` +- `onError` -- for network/auth errors + +`formatError()` from `@probo/helpers` normalizes error objects into user-facing strings for toast notifications. + +### Toast Notifications (universal) + +User-facing errors surface through `useToast()` from `@probo/ui`, backed by a Zustand store. The `Toasts` component is mounted once inside `Layout` -- never add it again in child routes. + +## Observability + +The TypeScript frontend has **no structured logging, metrics, or tracing**. This is a deliberate architectural choice. Errors surface to users via Relay typed error classes and React error boundaries. A small number of `console.log`/`console.error` calls exist for ad-hoc debugging. + +See [shared.md -- Frontend observability](../shared.md#frontend-observability) for context. diff --git a/.claude/guidelines/typescript-frontend/pitfalls.md b/.claude/guidelines/typescript-frontend/pitfalls.md new file mode 100644 index 000000000..a99d8eda9 --- /dev/null +++ b/.claude/guidelines/typescript-frontend/pitfalls.md @@ -0,0 +1,160 @@ +# Probo -- TypeScript Frontend -- Pitfalls + +> Auto-generated by potion-skill-generator. Last generated: 2026-03-30 +> Cross-cutting conventions: see [shared.md](../shared.md) + +## Deprecated Patterns + +### 1. Using `withQueryRef` in route definitions + +**What goes wrong**: New route definitions using `withQueryRef` will be rejected in code review. This is listed as an approval blocker. + +**Why**: The team is migrating to the Loader component pattern, which gives better control over loading states, Relay environment wrapping, and Suspense boundaries. + +**How to avoid**: Create a `*Loader.tsx` component that uses `useQueryLoader` + `useEffect` internally. See `apps/console/src/pages/organizations/documents/DocumentsPageLoader.tsx` for the canonical example. + +**Source**: Code review (PR #845) -- reviewer explicitly stated "stop using withQueryRef and use a page Loader component." + +### 2. Using `useMutationWithToasts` + +**What goes wrong**: The hook couples mutation execution with toast display in a way the team considers inflexible. + +**Why**: The team prefers explicit composition of `useMutation` + `useToast` for clearer control flow and error handling. + +**How to avoid**: Import `useMutation` from `react-relay` and `useToast` from `@probo/ui` separately. Handle success/error in `onCompleted`/`onError` callbacks. + +**Source**: Code review (PR #855) -- "don't use useMutationWithToasts instead use useMutation and useToast." + +### 3. Using `promisifyMutation` from `@probo/helpers` + +**What goes wrong**: Wrapping Relay mutations in a Promise hides the callback-based API that Relay expects and makes error handling inconsistent. + +**How to avoid**: Use `useMutation` with `onCompleted`/`onError` callbacks directly. + +**Source**: `contrib/claude/relay.md` -- explicitly marked as deprecated. + +### 4. Putting GraphQL operations in `hooks/graph/` files + +**What goes wrong**: New files in `hooks/graph/` violate the `relay/must-colocate-fragment-spreads` ESLint rule and the project mandate for colocated operations. Existing files in this directory are legacy. + +**How to avoid**: Define all `graphql` tagged templates inline in the component file that uses them. + +**Source**: `apps/console/CLAUDE.md` -- "Queries, fragments, and mutations are colocated in the component that uses them -- never in separate hooks/graph/ files." + +## Relay Environment Mismatches + +### 5. Using wrong Relay environment for page area (apps/console) + +**What goes wrong**: Using `coreEnvironment` inside an IAM page (`src/pages/iam/`) or `iamEnvironment` inside an organization page causes schema mismatches. Queries will fail because the schema does not match the environment's GraphQL endpoint. + +**Why**: The Relay compiler maps `src/pages/iam/` to the `iam` project and everything else to `core`. The environments must match. + +**How to avoid**: IAM pages must use `IAMRelayProvider`. Organization pages must use `CoreRelayProvider`. The `relay.config.json` sources mapping is the authority: `"apps/console/src/pages/iam": "iam"`, `"apps/console/src": "core"`. + +**Source**: Codebase pattern -- `apps/console/relay.config.json`. + +## Relay Store Update Pitfalls + +### 6. Forgetting `@appendEdge`/`@deleteEdge` directives on mutations + +**What goes wrong**: The UI does not reflect the mutation result until a full page reload. Items appear to not be created or not be deleted. + +**Why**: Without Relay store directives, the normalized store is not updated and the list connection remains stale. + +**How to avoid**: Always include `@prependEdge(connections: $connections)` or `@deleteEdge(connections: $connections)` in mutation GraphQL. Pass the `connections` variable obtained from `__id` on the connection fragment. Ensure `ConnectionHandler.getConnectionID()` uses the same arguments as the `@connection` directive. + +**Source**: Codebase pattern -- see `apps/console/src/pages/organizations/risks/RiskDetailPage.tsx`. + +### 7. Only first GraphQL error code is thrown by `@probo/relay` + +**What goes wrong**: If a response contains multiple GraphQL errors, only the first recognized error code is thrown as a typed exception. All subsequent errors are silently ignored. + +**Why**: `packages/relay/src/fetch.ts` short-circuits on the first `errors.find(...)` match. + +**How to avoid**: Be aware that error boundaries will only see the first error. If you need to handle multiple error codes, inspect the raw response in the `onCompleted` callback. + +**Source**: Codebase pattern -- `packages/relay/src/fetch.ts` lines 85-108. + +## UI Component Pitfalls + +### 8. Calling `useEditableRowContext()` outside `EditableRow` + +**What goes wrong**: Runtime exception -- the hook throws if called outside an `EditableRow` context. There is no fallback null guard. + +**How to avoid**: Always wrap `EditableCell` and `SelectCell` inside an `` parent. + +**Source**: Codebase pattern -- `packages/ui/src/Molecules/Table/EditableRow.tsx`. + +### 9. Mounting `` more than once + +**What goes wrong**: Toasts render twice because the Zustand store is module-level shared state. + +**How to avoid**: `` is already mounted inside `` from `@probo/ui`. Never add it again in child routes or page components. + +**Source**: Codebase pattern -- `packages/ui/src/Atoms/Toasts/Toasts.tsx`. + +### 10. Missing `theme.css` import in consuming apps + +**What goes wrong**: All design-token-based Tailwind classes (e.g., `bg-level-0`, `text-txt-primary`) render unstyled. The page looks completely broken. + +**Why**: `@probo/ui` uses Tailwind CSS v4 design tokens defined in `packages/ui/src/theme.css`. Without importing it, the custom utility classes resolve to nothing. + +**How to avoid**: Ensure the consuming app imports the theme CSS. See `packages/ui/.storybook/preview.tsx` for the import pattern. + +**Source**: Codebase pattern -- `packages/ui`. + +### 11. Passing `tv()` factory instead of calling it + +**What goes wrong**: The `className` prop receives `[object Object]` instead of a class string. + +**Why**: `tailwind-variants` `tv()` returns a function that must be called with variant props. + +**How to avoid**: Always call the factory: `badge({ variant, size })`, not `badge`. + +**Source**: Codebase pattern -- `packages/ui/src/Atoms/Button/Button.tsx`. + +## Snapshot Mode Pitfalls + +### 12. Forgetting snapshot mode on new list/detail pages (apps/console) + +**What goes wrong**: Users can mutate data on read-only snapshot views. Create/update/delete controls remain visible when viewing a snapshot. + +**How to avoid**: Check `useParams()` for `snapshotId`. When present, hide all mutation controls and use `/snapshots/:snapshotId/...` URL prefix. Define duplicate routes in the route file for both normal and snapshot paths. + +**Source**: Codebase pattern -- see `apps/console/src/routes/assetRoutes.ts` for duplicate route definitions, and `apps/console/src/pages/organizations/risks/RiskDetailPage.tsx` for conditional rendering. + +## Trust Center Path Prefix + +### 13. Hardcoding paths without `getPathPrefix()` (apps/trust) + +**What goes wrong**: URLs break in Probo-hosted mode where the app runs at `/trust/{slug}` instead of `/`. + +**Why**: The trust app supports two base URL modes. Hardcoding `/` as the path prefix breaks when the basename is `/trust/{slug}`. + +**How to avoid**: Always use `getPathPrefix()` from `apps/trust/src/utils/pathPrefix.ts` when constructing redirect or continue URLs manually. Never hardcode `/trust/` strings. + +**Source**: Codebase pattern -- every file that constructs a full URL in `apps/trust`. + +## Custom TypeScript Types for API Data + +### 14. Hand-writing interfaces that mirror GraphQL types + +**What goes wrong**: Types drift from the schema. TypeScript compiles but the runtime data shape may not match. + +**Why**: Relay codegen produces precise types from the schema. Hand-written types duplicate this and inevitably go stale. + +**How to avoid**: Always use Relay-generated fragment types from `__generated__/`. The custom `@probo/eslint-plugin-relay-types` enforces this. + +**Source**: `apps/console/CLAUDE.md` -- "Never create custom TypeScript types for API data." + +## Access Control in UI + +### 15. Putting state-based access control in UI conditionals + +**What goes wrong**: The frontend hides a button, but the API still accepts the mutation. Or a different frontend path (MCP, CLI) bypasses the check entirely. + +**Why**: Access control must be enforced in the backend ABAC policy system (`pkg/probo/policies.go`), not via frontend visibility toggles. The frontend permission fragments (`canCreate`, `canUpdate`, `canDelete`) reflect ABAC decisions -- they do not replace them. + +**How to avoid**: If a resource's state (e.g., archived) should prevent an operation, add the condition to the ABAC policy, not to a JSX conditional. + +**Source**: Code review (PR #855, frequency 3) -- "should we consider putting this logic in our ABAC."
