# Rocket.Chat

Monorepo: the main Meteor app lives in `apps/meteor/`, shared libraries in `packages/`, other services in `apps/` and `ee/`.

## Documentation index

Read the doc that matches the task instead of scanning `docs/` wholesale.

### Cross-cutting

- [docs/i18n.md](docs/i18n.md) — translation keys: where they live, naming, namespaces, interpolation, plurals, server-side `lng`, what the i18n linter enforces

### Frontend

- [docs/frontend/](docs/frontend/) — frontend guidelines, split by topic:
  - [typescript-conventions.md](docs/frontend/typescript-conventions.md) — ES modules, `import type`, `type` vs `interface`, `any` vs `unknown`
  - [migrating-from-javascript.md](docs/frontend/migrating-from-javascript.md) — gradual JS → TS migration
  - [react.md](docs/frontend/react.md) — component structure, naming, exports, explicit and generic props types
  - [building-components.md](docs/frontend/building-components.md) — application vs Fuselage components, styling rules, Storybook-first
  - [i18n.md](docs/frontend/i18n.md) — client side only: `useTranslation`, `Trans`, runtime keys, escaping (shared rules in [docs/i18n.md](docs/i18n.md))
- [docs/form-validation.md](docs/form-validation.md) — standardized form validation patterns
- [docs/anchor-navigation.md](docs/anchor-navigation.md) — deep-linking to a field via URL hash fragments

### Backend

- [docs/backend-folder-structure.md](docs/backend-folder-structure.md) — how `apps/meteor/` server code is organized and where new code goes
- [docs/api-endpoint-migration.md](docs/api-endpoint-migration.md) — migrating `API.v1.addRoute()` to the validated `API.v1.get()`/`.post()`/… pattern
- [docs/ajv-instances.md](docs/ajv-instances.md) — when to use `ajv` vs `ajvQuery` in `@rocket.chat/rest-typings`
- [docs/apps-engine-migration.md](docs/apps-engine-migration.md) — phased extraction of apps execution into a microservice

### Build and tooling
