GraphQL — A Query Language for APIs

type Project {
  name: String
  tagline: String
  contributors: [User]
}

{
  project(name: "GraphQL") {
    tagline
  }
}

{
  "project": {
    "tagline": "A query language for APIs"
  }
}

Зачем?

Есть же REST

{
    "name": "Mary",
    "posts": [
        { "title": "Learn GraphQL today" }
    ],
    "followers": [
        { name: "John" },
        { name: "Alice" },
        { name: "Sarah" },
    ]
}

Так давайте наколбасим DTOшки и не будем париться
