CLAUDE: webapp/platform/
Purpose
- Shared packages consumed by every Mattermost web experience (Channels, Boards, Playbooks, plugins).
- Changes here affect multiple products—coordinate across teams before merging.
Packages
| Package | Directory | Purpose |
|---|---|---|
@mattermost/types |
types/ |
TypeScript type definitions |
@mattermost/client |
client/ |
REST and WebSocket API client |
@mattermost/components |
components/ |
Shared React components |
@mattermost/shared |
shared/ |
Cross-product components and utilities for the web app and plugins (e.g. Button, WithTooltip). Prefer these over rolling your own |
@mattermost/eslint-plugin |
eslint-plugin/ |
Custom ESLint rules |
Workspace Basics
- Each subpackage is its own npm workspace with independent
package.json, tests, and build scripts. - Run commands with
npm run <script> --workspace=@mattermost/<pkg>(e.g.,@mattermost/client). - Versioning follows the monorepo; publishable artifacts come from CI pipelines.
Import Convention
Always import using the full package name:
// CORRECT
import {Client4} from '@mattermost/client';
// INCORRECT - never use relative paths
import Client4 from '../platform/client/src/client4';
Build Relationship
Platform packages are automatically built on npm install via postinstall hook. Build order: types → client/components.
Note: When developing in channels, changes in platform packages may need a rebuild if not using a watcher that supports them.
Adding Dependencies
When adding dependencies to platform packages:
npm add package-name --workspace=@mattermost/client
Expectations
- Follow
webapp/STYLE_GUIDE.md. - Maintain 100% TypeScript coverage; no
any. - Update downstream consumers when making breaking changes.
