Proposed changes (including videos or screenshots)

Migrate mailer and mailer.unsubscribe endpoints to the new OpenAPI-compatible chained route definition syntax with AJV body and response validation.

Changes

apps/meteor/app/api/server/v1/mailer.ts

  • Added ExtractRoutesFromAPI and declare module augmentation
  • Preserved permissionsRequired: ['send-mail'] for mailer endpoint
  • Preserved rateLimiterOptions for mailer.unsubscribe endpoint

Walkthrough

This pull request migrates mailer API endpoints from a deprecated addRoute pattern to a chainable .post() pattern with inline AJV response schemas for OpenAPI 3.0.3 documentation. Validators and type definitions are relocated from the rest-typings package into the meteor app's implementation, while rest-typings removes related exports and types.

109-109: Avoid inline lint-disable comments in implementation code.

Prefer a config-level override (or shared declaration-file convention) for this augmentation pattern instead of inline suppression comments.

As per coding guidelines: "Avoid code comments in the implementation".

Inline comments:
In `@apps/meteor/app/api/server/v1/mailer.ts`:
- Around line 27-28: The OpenAPI change added nullable: true to the request
schema fields dryrun and query which expands the contract to accept explicit
nulls; revert those schema entries in the mailer.ts request/body definition so
dryrun and query remain optional but not nullable (remove the nullable: true key
for the dryrun and query properties in the schema object), ensuring validation
semantics for dryrun and query are preserved.

File: packages/ddp-client/src/legacy/types/SDKLegacy.ts:34-34
Timestamp: 2026-02-25T20:10:16.987Z
Learning: In the RocketChat/Rocket.Chat monorepo, packages/ddp-client and apps/meteor do not use TypeScript project references. Module augmentations in apps/meteor (e.g., declare module 'rocket.chat/rest-typings') are not visible when compiling packages/ddp-client in isolation, which is why legacy SDK methods that depend on OperationResult types for OpenAPI-migrated endpoints must remain commented out.

Learning: During PR reviews that touch endpoint files under apps/meteor/app/api/server/v1, enforce strict scope: if a PR targets a specific endpoint (e.g., rooms.favorite), do not propose changes to unrelated endpoints (e.g., rooms.invite) unless maintainers explicitly request them. Focus feedback on the touched endpoint's behavior, API surface, and related tests; avoid broad cross-endpoint changes in the same PR unless requested.

Learning: In this repository (RocketChat/Rocket.Chat), Biome lint rules are not used even if a biome.json exists. When reviewing TypeScript files (e.g., packages/ui-voip/src/providers/useMediaSession.ts), ensure lint suggestions do not reference Biome-specific rules. Rely on general ESLint/TypeScript lint rules and project conventions instead.

49-104: Route migration preserves the important guards and behavior.

Auth requirements, send-mail permission, rate limiting, and handler flow are retained while adding explicit response schemas.


106-111: Module augmentation is safe for isolated package compilation.

Verification confirms no active legacy SDK typing depends on the migrated mailer endpoints. The module augmentation in apps/meteor will not cause typing issues when packages/ddp-client compiles in isolation, as no legacy SDK methods reference these endpoints.

.changeset/migrate-mailer-openapi.md (1)

2-3: The review comment is based on an incorrect premise.

Mailer types were never exported from @rocket.chat/rest-typings. The changeset describes a refactoring of endpoint implementation within apps/meteor (migrating from addRoute to the chainable .post() pattern), not a removal of public types from rest-typings. Since the rest-typings public API surface is unchanged, the patch level is appropriate.

Likely an incorrect or invalid review comment.

Hey, thanks for the contribution! 🙏

I'm closing this PR because the endpoint(s) covered here have already been migrated as part of a larger batch migration I'm working on (see #39820). I decided to go with a mass migration approach because reviewing individual PRs for each endpoint was taking too much of my time.

That said, you're more than welcome to help by reviewing and testing the changes in #39820 to make sure everything is working correctly. Your input would be really valuable!

Thanks again for your effort! 🚀
