Operations

GraphQL is a specification for communicating with the server. We communicate with it—asking for data and telling it to do things—by sending operations. There are three types of operations:

• query fetches data
• mutation changes and fetches data
• subscription tells the server to send data whenever a certain event occurs

Operations can have names, like AllTheStars in this query operation:

query AllTheStars {
  githubStars
}
