Examples
# Simple commit
git commit -m "feat: add user registration"
# Detailed commit
git commit -m "feat(api): add rate limiting
- Add token bucket rate limiter
- Configure limits per endpoint
- Add rate limit headers
Closes #123"
Debugging Tips
1. Binary Search Location
git bisect start
git bisect bad HEAD
git bisect good <stable-commit>
git bisect run bun test
2. Log Debugging
logger.debug("Processing user", { userId, action })
logger.info("User created", { userId, email })
logger.warn("Rate limit exceeded", { ip, limit })
logger.error("Database error", { error: err.message })
3. Breakpoint Debugging
function process(data: Data) {
debugger // Pause here
return transform(data)
}
4. Type Checking
bun tsc --noEmit
grep -r ": any" src/
Performance Optimization
1. Measure First
const start = performance.now()
await expensiveOperation()
const duration = performance.now() - start
if (duration > 100) {
logger.warn(`Slow operation: ${duration}ms`)
}
2. Batch Processing
// Batch processing
await Promise.all(items.map((item) => process(item)))
// Avoid serial processing
for (const item of items) {
await process(item)
}
3. Caching
const cache = new Map<string, Data>()
async function getData(key: string): Promise<Data> {
if (cache.has(key)) {
return cache.get(key)!
}
const data = await fetchFromDB(key)
cache.set(key, data)
return data
}
Security Checklist
Pre-Release Check
- No hardcoded keys
- Environment variables configured
- Input validation complete
- Output escaped
- Permission checks in place
- Error handling secure
- Dependencies vulnerability-free
- HTTPS enforced
Sensitive Operations
- Passwords hashed
- Token expiration reasonable
- Sensitive data encrypted
- Logs sanitized
- Security headers configured
Documentation Standards
Code Comments
/**
* Validates user input data.
*
* @param data - User data to validate
* @returns Validation result with validity flag and error messages
* @throws {ValidationError} When data format is invalid
*
* @example
* ```ts
* const result = validateUserData({ name: 'John', email: 'john@example.com' });
* if (result.valid) {
* // Process valid data
* }
* ```
*/
function validateUserData(data: unknown): ValidationResult {
// Implementation
