🤔 REST vs GraphQL: Which API?
Both are popular. REST is traditional. GraphQL is modern. Choose the right API for your project.
✅ REST API
// Multiple endpoints GET /api/users/1 GET /api/users/1/posts GET /api/posts/1/comments // Over-fetching // Gets all fields
✅ GraphQL
// Single endpoint
query {
user(id: 1) {
name
email
posts {
title
comments {
text
}
}
}
}
// Only requested fields
