GraphQL
Graph Query Language
A query language for APIs that lets clients request exactly the data they need in a single request.
Technical Detail
GraphQL APIs use HTTP methods as verbs: GET (read), POST (create), PUT (replace), PATCH (partial update), DELETE (remove). Resources are identified by URIs and represented in JSON. RESTful design requires statelessness — each request contains all information needed for processing. HATEOAS (Hypermedia as the Engine of Application State) is the often-ignored constraint where responses include links to related actions, enabling API self-discovery.
Example
```javascript // GraphQL example const input = 'sample data'; const result = process(input); console.log(result); ```
