API Versioning

Overview

APIs evolve, but breaking changes break clients. This skill covers versioning strategies (URL path, headers, query params), deprecation workflows, backwards-compatible changes, and migration patterns for REST and GraphQL APIs.

Instructions

// routes/v1/projects.ts — Version 1 routes
import { Router } from 'express'

const v1Router = Router()
