Comm Project Development Guide

Build & Test Commands

  • Run tests: yarn workspace [lib|web|keyserver|native] test
  • Test all packages: yarn jest:all
  • Run lint: yarn eslint:all
  • Fix lint issues: yarn eslint:fix
  • Check Flow types: yarn flow:all or yarn workspace [workspace] flow
  • Run dev server: yarn workspace [workspace] dev
  • Clean install: yarn cleaninstall

Code Style

Types

  • Use Flow for static typing with strict mode enabled
  • Always include // @flow annotation at the top of JS files
  • Export types with explicit naming: export type MyType = {...}

Formatting

  • Prettier with 80-char line limit
  • Single quotes, trailing commas
  • Arrow function parentheses avoided when possible
  • React component files named \*.react.js

Naming

  • kebab-case for filenames (enforced by unicorn/filename-case)
  • Descriptive variable names

Imports

  • Group imports with newlines between builtin/external and internal
  • Alphabetize imports within groups
  • No relative imports between workspaces - use workspace references

React

  • Use functional components with hooks
  • Follow exhaustive deps rule for useEffect/useCallback
  • Component props should use explicit Flow types

Error Handling

  • Use consistent returns in functions
  • Handle all promise rejections
