Install all dependencies: + ```bash + npm install + ``` + +2. The project uses the following development tools: + - **TypeScript**: For static typing + - **Webpack**: For module bundling + - **Karma**: For test running + - **Jasmine**: For testing framework + - **ESLint**: For code linting + - **Prettier**: For code formatting + +### Building the Project + +To build the project: + +```bash +npm run build +``` + +This compiles TypeScript files and generates distribution bundles in the `dist/` directory. + +### Development Server + +For development with hot reload: + +```bash +npm run serve +``` + +This starts a development server where you can test your changes in real-time. + +### Available Scripts + +- `npm run build`: Build the project for production +- `npm run serve`: Start development server +- `npm run test`: Run the test suite +- `npm run test:watch`: Run tests in watch mode +- `npm run lint`: Lint code using ESLint +- `npm run lint:fix`: Automatically fix linting issues +- `npm run format`: Format code using Prettier +- `npm run clean`: Remove build artifacts + +## Project Structure + +Understanding the project layout is essential for efficient contributions: + +``` +firebaseui-web/ +├── src/ # Source code +│ ├── ui/ # UI components +│ ├── auth/ # Authentication logic +│ ├── storage/ # State and storage utilities +│ └── [feature-modules]/ # Feature-specific modules +├── dist/ # Compiled output (generated) +├── npm-module/ # NPM package configuration +├── public/ # Static assets +├── test/ # Test files +├── javascript/ # JavaScript examples and integrations +├── .husky/ # Git hooks +├── webpack.config.js # Webpack configuration +├── tsconfig.json # TypeScript configuration +├── karma.conf.js # Karma test runner config +├── .eslintrc.js # ESLint configuration +├── .prettierrc.js # Prettier configuration +└── package.json # Project dependencies +``` + +### Key Directories + +**src/ui/**: Contains UI components like account chooser, password recovery, signin page, etc. + +**src/auth/**: Contains authentication-related utilities and managers. + +**test/**: Contains unit tests and integration tests for all features. + +**javascript/**: Contains example implementations and integrations. + +## Making Changes + +### Creating a Feature Branch + +Always create a new branch for your changes: + +```bash +git checkout -b feature/your-feature-name +``` + +Use descriptive branch names that follow this pattern: +- `feature/short-description` - For new features +- `fix/short-description` - For bug fixes +- `docs/short-description` - For documentation improvements +- `refactor/short-description` - For refactoring +- `test/short-description` - For test improvements +- `perf/short-description` - For performance improvements + +### Development Workflow + +1. **Create your branch**: `git checkout -b feature/my-feature` +2. **Make your changes**: Edit files as needed +3. **Run tests locally**: `npm run test` +4. **Run linter**: `npm run lint` +5. **Format code**: `npm run format` +6. **Commit your changes**: Follow commit message guidelines (see below) +7. **Push to your fork**: `git push origin feature/my-feature` +8. **Create a Pull Request**: Describe your changes clearly + +### Guidelines for Code Changes + +- **Keep changes focused**: Each pull request should address a single concern. +- **Update related files**: If you modify a feature, update relevant tests and documentation. +- **Avoid breaking changes**: Maintain backward compatibility unless explicitly approved. +- **Add comments**: Document complex logic or non-obvious code. +- **Remove dead code**: Don't commit commented-out code or unused imports. +- **Follow existing patterns**: Maintain consistency with the codebase style. + +## Testing + +### Understanding the Test Suite + +The FirebaseUI Web project uses a comprehensive testing strategy: + +- **Unit Tests**: Test individual functions and components in isolation +- **Integration Tests**: Test how components work together +- **UI Tests**: Test user interface behavior and rendering + +### Writing Tests + +When adding new features, you must include tests. Follow these guidelines: + +1. **Test Location**: Place tests in the `test/` directory with the same structure as `src/`. +2. **File Naming**: Name test files with `.test.ts` or `.spec.ts` suffix. +3. **Test Structure**: Use Jasmine's describe/it syntax. + +Example test structure: + +```typescript +describe('MyComponent', () => { + let component: MyComponent; + + beforeEach(() => { + component = new MyComponent(); + }); + + afterEach(() => { + // Cleanup + }); + + it('should initialize with default values', () => { + expect(component.value).toBe(0); + }); + + it('should update value when setValue is called', () => { + component.setValue(10); + expect(component.value).toBe(10); + }); + + it('should handle edge cases correctly', () => { + component.setValue(-1); + expect(component.value).toBe(0); // or your expected behavior + }); +}); +``` + +### Running Tests + +```bash +# Run all tests +npm run test + +# Run tests in watch mode (re-run on file changes) +npm run test:watch + +# Run specific test file +npm run test -- path/to/specific.test.ts +``` + +### Test Coverage + +Maintain or improve test coverage with your changes: + +```bash +# Check coverage report +npm run test -- --coverage +``` + +Aim for high coverage, especially for: +- Core authentication logic +- UI components +- Utility functions +- Public APIs + +### Testing Best Practices + +1. **Test behavior, not implementation**: Focus on what the code does, not how it does it. +2. **Use descriptive test names**: Test names should clearly describe what is being tested. +3. **Keep tests isolated**: Tests should not depend on other tests or share state. +4. **Mock external dependencies**: Use mocks for Firebase SDK and other external services. +5. **Test error cases**: Include tests for error handling and edge cases. +6. **Keep tests fast**: Avoid unnecessary delays or long-running operations. + +## Code Style and Standards + +### TypeScript Standards + +- Use strict TypeScript mode (`strict: true` in tsconfig.json) +- Define types explicitly - avoid `any` type +- Use interfaces for complex object structures +- Use enums for fixed sets of values +- Export public APIs clearly + +Example: + +```typescript +// Good +interface UserProfile { + uid: string; + email: string; + displayName?: string; +} + +export class AuthManager { + private user: UserProfile | null = null; + + public getUser(): UserProfile | null { + return this.user; + } +} + +// Avoid +export class AuthManager { + private user: any = null; + + public getUser() { + return this.user; + } +} +``` + +### JavaScript/CSS Standards + +- Use modern ES6+ syntax +- Avoid global variables - use modules +- Use meaningful variable and function names +- Write CSS that follows BEM (Block Element Modifier) naming convention +- Use flexbox and CSS Grid for layouts +- Ensure responsive design for mobile, tablet, and desktop + +### Naming Conventions + +- **Classes**: PascalCase (e.g., `AuthManager`, `SignInPage`) +- **Functions**: camelCase (e.g., `validateEmail`, `handleSubmit`) +- **Constants**: UPPER_SNAKE_CASE (e.g., `DEFAULT_TIMEOUT`, `MAX_RETRIES`) +- **Private members**: Prefix with underscore (e.g., `_internalState`) +- **HTML/CSS classes**: kebab-case (e.g., `sign-in-form`, `error-message`) + +### Linting and Formatting + +All code must pass linting and formatting checks: + +```bash +# Check linting +npm run lint + +# Fix linting issues automatically +npm run lint:fix + +# Format code +npm run format +``` + +Before committing, ensure your code passes these checks. Pre-commit hooks will automatically run these checks. + +## Commit Messages + +### Commit Message Format + +Follow this format for commit messages: + +``` +(): + + + +
