## 🎯 Code Style Guidelines

### JavaScript/Node.js

* Use **ES Modules** (`import` / `export`)
* Prefer **async/await** over callbacks
* Use `const` / `let` (avoid `var`)
* **camelCase** for variables and functions
* **PascalCase** for classes
* **UPPER\_SNAKE\_CASE** for constants

### File Naming

* **kebab-case** for general files: `backup-manager.js`
* **PascalCase** for class files: `BackupManager.js`
* **camelCase** for utilities: `fileUtils.js`

### Documentation

* JSDoc for functions and classes
* Include examples
* Keep **README.md** updated
* Log breaking changes in **CHANGELOG.md**

### Logging

* Use the built-in logging system (`log.info`, `log.success`, etc.)
* Emojis encouraged
* Provide context for errors

---

## 🧪 Testing Guidelines

### Structure

```javascript
describe('Feature Name', () => {
  it('should do something specific', () => {
    const input = 'test';
    const result = functionToTest(input);
    expect(result).toBe('expected');
  });
});
```

### Goals

* 90%+ coverage
* Test happy paths, errors, and edge cases
* Use clear, descriptive test names

### Commands

```bash
npm run test:all
npm run test:unit
npm run test:integration
npm run test:coverage
```
