Proposed changes (including videos or screenshots)

storybook-dark-mode is the seventh package in the Fuselage migration — another leaf with no internal dependencies. The code comes from RocketChat/fuselage at version 4.2.1, where it lives as a fork of hipstersmoothie/storybook-dark-mode (MIT, Andrew Lisowski) — Fuselage took it over in fuselage#1849 and has carried it on its own 4.x line since.

Worth being explicit about what this replaces, because it is not a like-for-like swap of a package we already had. @rocket.chat/storybook-config and @rocket.chat/livechat were consuming the upstream addon, storybook-dark-mode@^5.0.0 from npm, which resolved to 5.0.0 — and that release declares peerDependencies: { storybook: "^10.0.0" } while this repo is on Storybook 9.1.20. The Fuselage fork is the branch of this addon that actually targets Storybook 9 (it imports from storybook/internal/*, storybook/manager-api and storybook/theming). So this both brings the package in-tree and puts the consumers on the copy built for the Storybook version we run.

Five commits:

  1. chore: migrate @rocket.chat/storybook-dark-mode from Fuselage — the package lands at packages/storybook-dark-mode with its source, preset.js, changelog, LICENSE and build configs. No workspaces glob entry was needed: the root package.json already globs packages/*. dist/ and .turbo/ are gitignored, so only the twelve tracked files show up. The same commit flips both consumers to @rocket.chat/storybook-dark-mode — two package.json entries, the addon id in packages/storybook-config/src/main.ts and packages/livechat/.storybook/main.ts, and the useDarkMode / DARK_MODE_EVENT_NAME imports in preview.tsx and DocsContainer.tsx.

    Relative to the Fuselage source the code is unchanged in behaviour. Apart from the matchMedia call in commit 5 below, everything that differs is local convention:

    • Prettier reformatting to this repo's config (tabs, 140 columns) — that is the bulk of the diff noise in Tool.tsx.
    • The two interface declarations become type aliases, per docs/frontend/typescript-conventions.md.
    • One eslint-disable-next-line @typescript-eslint/no-unused-vars on the import * as React in src/preset/manager.tsx, which is needed for the classic JSX runtime but reads as unused here.
    • lint/lint:fix replace Fuselage's lint-all workspace binary with plain eslint ., matching @rocket.chat/storybook-config.
    • eslint, prettier and the React @types pin to this repo's versions.

    The addon's public surface is untouched: useDarkMode(), DARK_MODE_EVENT_NAME, UPDATE_DARK_MODE_EVENT_NAME, the darkMode parameter and the sb-addon-themes-3 localStorage key all behave exactly as before, so no story or preview needed changing beyond the import path.

  2. chore: use shared tsconfig in @rocket.chat/storybook-dark-modetsconfig.json extends @rocket.chat/tsconfig/client.json instead of Fuselage's tsconfig.base.json, which lets 40 lines of restated compiler options go; only jsx: "react" has to stay, since the addon uses the classic runtime. rimraf drops out of devDependencies in favour of rm -rf dist, the way every other package here spells it.

  3. chore: fix @rocket.chat/storybook-dark-mode manifest after the migration — three things the copy left behind:

    • repository.url still pointed at RocketChat/fuselage; it now points here, keeping type and directory (the path is the same in both repos).
    • storybook was not declared at all. The source imports storybook/preview-api, storybook/manager-api, storybook/theming and the internal storybook/internal/{components,core-events,types}, but the manifest listed only react/react-dom as peers — upstream 5.0.0 did declare storybook: ^10.0.0, and the fork dropped it. It resolved only because storybook is hoisted to the workspace root, which means the package could not build in isolation and the internal (non-public) APIs it leans on had no version contract. Now ^9.1.20 in devDependencies (same range as @rocket.chat/storybook-config, so it dedupes onto the existing resolution) and ^9.0.0 in peerDependencies. No new packages enter the lockfile and no new peer warnings appear — both consumers already declare Storybook 9.
    • the per-package volta pin was missing, so the repo's Node version was not picked up inside the package directory. 58 of the 61 manifests under packages//apps/ carry {"extends": "../../package.json"}; Fuselage pins only at its root, so there was nothing to copy.
  4. chore: stop emitting declarations from the esm and cjs build passesclient.json turns declaration and declarationMap on, so every one of the three tsc passes emitted .d.ts and .d.ts.map. Only the third is referenced — types points at dist/ts/index.d.ts — so the copies under dist/esm and dist/cjs were dead weight in the tarball (files ships all of dist). Both are now off for the two JS-only passes, leaving dist/ts as the single source of types. Not something the migration introduced: Fuselage's tsconfig.base.json sets the same two flags, and its published dist/esm carries the same redundant declarations.

  5. chore: drop the redundant optional call on window.matchMedia — the one place where the code, not just its formatting, differs from Fuselage. prefersDark was initialised with window.matchMedia?.('(prefers-color-scheme: dark)'), but Window.matchMedia is non-optional in lib.dom, so TypeScript erases the ?. from the resulting type: prefersDark was already MediaQueryList, never MediaQueryList | undefined. Which is just as well, because the downstream prefersDark.matches and prefersDark.addListener(…) are unguarded and would throw on undefined anyway. The optional call bought nothing except the appearance of a guard, and where matchMedia really is missing the only difference is whether the throw lands at module evaluation or at first render.

Net effect on the lockfile is fewer packages, not more: the fork's three runtime dependencies (@storybook/global, @storybook/icons, fast-deep-equal) all dedupe against ranges the tree already had, while dropping upstream 5.0.0 removes @storybook/icons@2.0.2, memoizerific and map-or-similar.

Issue(s)

ARCH-2360

Steps to test or reproduce

Nothing changes for the end user — this is Storybook tooling only, and no application code is touched.

  1. yarn workspace @rocket.chat/storybook-dark-mode build — three tsc passes emit JS plus sourcemaps into dist/esm and dist/cjs, and declarations into dist/ts only. lint is clean.
  2. yarn workspace @rocket.chat/storybook-config build — clean, which is the real check on the switchover: it typechecks useDarkMode and DARK_MODE_EVENT_NAME against packages/storybook-dark-mode/dist/ts.
  3. yarn workspace @rocket.chat/gazzodown build-storybook — completes, i.e. Storybook resolves the workspace addon through getAbsolutePath('@rocket.chat/storybook-dark-mode')preset.jsdist/esm/preset/manager and bundles its manager entry.
  4. yarn workspace @rocket.chat/gazzodown storybook (or any other host, plus packages/livechat) — the sun/moon toggle is in the toolbar, flips manager and preview themes, persists across reloads, and the Fuselage palette follows it in both stories and docs pages.
  5. node_modules/@rocket.chat/storybook-dark-mode should be a symlink to ../../packages/storybook-dark-mode, and storybook-dark-mode should be gone from the tree.

Further comments

The peer range says ^9.0.0, which is a claim worth reviewing. The addon reaches into storybook/internal/* — non-public API with no stability guarantee across minors, let alone the whole major. ^9.0.0 is the honest reading of what it targets today, but if the Storybook reconciliation work moves us to 10 this fork has to follow, and that is where upstream 5.x already is.

matchMedia is still assumed to exist. Commit 4 drops the optional call that pretended otherwise, but it does not add a real guard: prefersDark.matches and prefersDark.addListener(…) remain unguarded, so a host without matchMedia throws. Making the guard real means typing prefersDark as MediaQueryList | undefined and handling it at all three use sites — more churn against the fork, and only worth it if we expect to run the manager somewhere other than a browser.

No publishConfig.access: public. The ticket flags this package as the only public one in Fuselage without it, and asks that we confirm how it currently reaches npm as a scoped package before touching its publish path — so the manifest is unchanged on that point. Nothing publishes from here until ARCH-2350 lands.

Consumers use workspace:~, not workspace:^. The ticket says ^. ~ is what the surrounding packages use for internal workspace dependencies and what the emitter migration (#41768) settled on, so I stayed consistent; trivial to flip if the migration plan depends on ^.

npm trusted publishing still needs repointing. As the ticket notes, the publisher is bound to RocketChat/fuselage + .github/workflows/cd.yml. That is an npm UI change by an org owner and cannot be done from this repo.

The README.md was not carried over. Fuselage ships the upstream addon's docs alongside the package; the emitter migration did not bring a readme either, so I followed that, but for a forked third-party addon the usage docs arguably have more reason to travel with the code. Happy to add it.

No changeset. @rocket.chat/storybook-config, which takes it as a regular dependency, is private: true; @rocket.chat/livechat takes it as a devDependency, so its published bundle is unaffected. Nothing here belongs in end-user release notes.

Do not manually set htmlFor, id, aria-describedby, or role attributes when using these wrappers. This automatic wiring does not apply to plain rocket.chat/fuselage components, which require explicit ID wiring per the accessibility docs. In code reviews, prefer using fuselage-forms wrappers for form fields and verify there is no unnecessary manual ID/aria wiring in files that use these wrappers. If a component uses plain fuselage components, ensure proper id wiring as per docs.

Learning: In Rocket.Chat’s monorepo, when reviewing a dependency entry and flagging that a specific version “does not exist” (e.g., in package.json), first verify the exact package/version directly against the npm registry (use URLs like https://registry.npmjs.org/<package>/<version> or https://www.npmjs.com/package/<package>/v/<version>). Do not rely on web search results for this check, since they may be stale or cached and may not reflect the latest published versions.

Instead, verify the version directly against the npm registry (e.g., via the npm registry API or the canonical package URL https://www.npmjs.com/package/<package>/v/<version>) before deciding that a version bump is invalid. If the version is present in the npm registry, do not flag it as invalid.

Learning: In Rocket.Chat, there are two different `ModalBackdrop` components with different prop APIs. During review, confirm the import source: (1) `rocket.chat/fuselage` `ModalBackdrop` uses `ModalBackdropProps` based on `BoxProps` (so it supports `onClick` and other Box/DOM props) and does not have an `onDismiss` prop; (2) `rocket.chat/ui-client` `ModalBackdrop` uses a narrower props interface like `{ children?: ReactNode; onDismiss?: () => void }` and handles Escape keypress and outside mouse-up, and it does not forward arbitrary DOM props such as `onClick`. Flag mismatched props (e.g., `onDismiss` passed to the fuselage component or `onClick` passed to the ui-client component) and ensure the usage matches the correct component being imported.

Three things the copy from Fuselage left behind:

- `repository.url` still pointed at `RocketChat/fuselage`;
- `storybook` was not declared at all, even though the source imports
  `storybook/preview-api`, `storybook/manager-api`, `storybook/theming` and
  three `storybook/internal/*` paths — it only resolved through root hoisting.
  Declared as a devDependency so the package builds standalone, and as a
  peerDependency to encode the Storybook 9 host contract;
- the per-package `volta` pin was missing, so the repo's Node version was not
  picked up inside the package directory.

`Window.matchMedia` is non-optional in `lib.dom`, so TypeScript erased the `?.`
from the resulting type and `prefersDark` was already `MediaQueryList` rather
than `MediaQueryList | undefined` — which is what the unguarded `.matches` and
`.addListener()` uses downstream rely on. Removing it makes the call agree with
the type.

`@rocket.chat/tsconfig/client.json` turns `declaration` and `declarationMap`
on, so all three `tsc` passes emitted `.d.ts` and `.d.ts.map` files. Only the
third one is referenced: `types` points at `dist/ts/index.d.ts`, leaving the
copies in `dist/esm` and `dist/cjs` as dead weight in the tarball. Turned off
for the two passes that only need JS, so `dist/ts` is the single source of
types.
