What are best practices for designing consistent JSON API responses? Consistent JSON API responses design करने की best practices क्या हैं?

Answer

A consistent response structure makes an API predictable and easier for consumers to parse, regardless of success or failure.

// Success response
{
  "success": true,
  "data": { "id": 1, "name": "John" },
  "meta": { "page": 1, "total": 50 }
}

// Error response
{
  "success": false,
  "message": "Validation failed",
  "errors": { "email": ["The email field is required."] }
}
PracticeWhy it matters
Consistent envelope (success/data/errors)Predictable parsing on client side
snake_case or camelCase consistentlyAvoids confusion across endpoints
Never leak stack tracesSecurity - avoid exposing internals
Include pagination metaHelps clients build UI navigation

Consistent response structure API को predictable बनाता है और consumers के लिए parse करना आसान बनाता है।

// Success
{
  "success": true,
  "data": { "id": 1, "name": "John" }
}

// Error
{
  "success": false,
  "message": "Validation failed",
  "errors": { "email": ["The email field is required."] }
}
