feat(methods): add chat.postMessage example - #139
Merged
Conversation
Add a methods/ chat.postMessage example verified by tsc --checkJs + Biome lint, with no runtime test. The type-check validates the payload against @slack/web-api's real ChatPostMessageArguments type, catching wrong or misspelled arguments (e.g. chnnel -> TS2561) without a mock server. This is an alternative to the fetch-stub runtime-test approach for side-by-side comparison. Co-Authored-By: Claude <svc-devxp-claude@slack-corp.com>
Add methods to the CI matrix and use `npm test --if-present` so the type-check-only methods example (which has no test script) passes CI while still running lint and check. Co-Authored-By: Claude <svc-devxp-claude@slack-corp.com>
@slack/web-api v8 is now GA; move off the 8.0.0-rc.2 release candidate to the stable ^8.0.0 range, matching the caret style used by block-kit. Co-Authored-By: Claude <svc-devxp-claude@slack-corp.com>
Match the runtime-test branch: add @slack/cli-hooks, a .slack/ workspace, and a chat manifest.json requesting only chat:write. Move scopes out of the README into the manifest and document the `slack install` flow with the method's exact docs description. Co-Authored-By: Claude <svc-devxp-claude@slack-corp.com>
Move @slack/cli-hooks to stable ^2.0.0 (get-hooks bin unchanged) and remove skipLibCheck so tsc fully type-checks library declarations by default, matching block-kit. The tsconfig already scopes include to src only (this variant has no tests). Co-Authored-By: Claude <svc-devxp-claude@slack-corp.com>
Move methods/chat/ to methods/src/chat/ and collapse the inner src/ directory so the example sits at methods/src/chat/chat-post-message.js. Repoint the top-level README to the specific chat.postMessage doc and implementation path; the per-family README is dropped in favor of the single methods index. Replace the tsconfig-driven check with an inline tsc invocation (tsc --checkJs --noEmit --types node src/**/*.js) and remove methods/tsconfig.json.

The example reads one variable (SLACK_TOKEN), so 'an environment variable' is more accurate than the plural.
