JSON Best Practices Every Developer Should Know

JSON is the lingua franca of modern web APIs. These best practices keep your data interoperable and performant.
Use consistent naming
Pick camelCase or snake_case and stick with it across the entire API.
Validate against schemas
Use JSON Schema or Zod to validate payloads at runtime.
Keep payloads small
Send only fields the client needs. Use pagination and gzip/brotli compression.
Version your APIs
Use /v1/ in URLs or version headers. Breaking changes need a clear migration path.
