Development

Code Formatting & Translation Validation

This project uses automatic code formatting and translation validation via Git hooks (Husky). When you commit code:

• JavaScript/TypeScript files are automatically formatted with Prettier
• Elixir files in packages/castmill/ are automatically formatted with mix format
• Translation files (i18n) are automatically validated for 100% coverage across all 9 languages

No manual formatting or translation checking needed! Just git commit and:

1. Your code will be formatted automatically
2. Translation coverage will be validated
3. Commit will be blocked if translations are incomplete

You can still format and validate manually if needed:

yarn format:all                         # Format all frontend packages
cd packages/castmill && mix format      # Format Elixir code
yarn check-translations                 # Validate i18n coverage

See .husky/README.md for more details.
