Getting to know GraphQL

The short version

GraphQL is a query language for APIs and a runtime to execute those queries. It gives you exactly the data you need — nothing more, nothing less.

What is GraphQL?

Precise Queries

Request exactly the fields you need - no more over-fetching or under-fetching.

Single Endpoint

Access all your data with a single endpoint - no need for multiple REST calls.

Why GraphQL?

Faster development cycles
Consistent patterns across clients
Easier to evolve APIs over time

A Simple Query Example

query ListDevices {
  devices {
    id
    name
    status
    lastCheckIn
  }
}

{
  "data": {
    "devices": [
      { "id": "1", "name": "Server-01", "status": "Online" },
      { "id": "2", "name": "Laptop-22", "status": "Offline" }
    ]
  }
}
