GraphQL

GraphQL is a query language for APIs. Unlike REST, where you often get too much or too little data (Over/Under fetching), GraphQL allows the client to ask for exactly what they need.

"Give me just the name and age." -> Server returns just the name and age.

Query

query {
user(id: "1") {

name
email
posts

}
}

Response (JSON)

{
  "data": {
    "user": {
      "name": "Alice"
    }
  }
}
