<strong>GraphQL</strong> is a query language that lets clients request exactly the data they need, while <strong>REST</strong> returns fixed data structures from predefined endpoints. GraphQL offers more flexibility; REST is simpler and more widely adopted.
The Restaurant Menu Analogy
REST is like a set menu—you get combo #1, #2, or #3 with predefined items. GraphQL is à la carte—you specify exactly which items you want, nothing more, nothing less.
REST (Set Menu)
Fixed meal combos
GraphQL (À la carte)
Pick exactly what you want
Kitchen (Server)
Prepares your order
Needs Specific Data
Different Approaches
Returns Data
REST: Multiple endpoints
GET /users/1, GET /posts/1, GET /comments/1
GraphQL: Single endpoint
POST /graphql with specific query
REST: Fixed response
Returns all user fields even if you need only name
GraphQL: Custom response
Returns only the fields you requested
Wrong
"GraphQL is always better than REST"
Correct
<strong>Each has trade-offs</strong>. REST is simpler, cacheable, and widely understood. GraphQL offers flexibility but adds complexity. Choose based on your needs.
Mobile app fetching user data:
REST: 3 API calls (user, posts, comments) = 3 round trips
GraphQL: 1 query gets user, posts, and comments = 1 round trip
REST: Over-fetching (get all fields, use only some)
GraphQL: Exact data (request only name and email)
