GraphQL is a query language for APIs and a runtime for fulfilling those queries with your existing data. It provides a more efficient and powerful alternative to traditional REST APIs by allowing clients to request exactly the data they need.
Key Features ✅
- Flexible Data Fetching: Clients can specify the structure of the response.
- Single Endpoint: All operations are performed through one URL.
- Strong Typing: Schemas define the types of data available.
- Real-time Updates: Support for subscriptions (optional).
How to Get Started 🚀
- Define a Schema: Use SDL (Schema Definition Language) to describe your data.
- Create Resolvers: Implement logic to fetch data from your backend.
- Send Queries: Use
GET
orPOST
requests to interact with the API.
Example Query 📝
query {
user(id: "1") {
name
email
posts {
title
content
}
}
}
Best Practices 🛠
- Always validate input to prevent errors.
- Use pagination for large datasets.
- Document your schema for clarity.
