GraphQL solves problems

1

What is GraphQL?

Schema definition language

Query language

Community of tools

Strong typing

type Message {
  id: ID!
  content: String
  user: User
  date: Int
}

type User {
  id: ID!
  name: String
  email: String
  avatarUrl: String
}

type Query {
  messages: [Message]
}

Strong typing

Help prevent errors

Improve the debugging experience

More explicit API (auto Docs)

Query only the data you need

{
  messages {
    id
    content
    user {
      id
      name
    }
  }
}
{
  "data": {
    "messages": [
      {
        "id": "0",
        "content": "Are you enjoying the conference?",
        "user": {
          "id": "0",
          "name": "Anne"
        }
      },
      {
        "id": "1",
        "content": "Absolutely!",
        "user": {
          "id": "1",
          "name": "Yoan"
        }
      }
    ]
  }
}

Query only the data you need

Reduce transfer size

No waterfall requests

Get predictable data shape

Clear and simple structure

Version-less

Add new fields

Deprecate old ones

Strong typing

Query language

Simpler architecture

Version-less
