mutationField

Mutations are usually best split up, and are one of the most common use-cases for extendType. mutationField exists as a shorthand for this common case:

1export const createUser = mutationField('createUser', {
2  type: SomeType,
3  resolve() {
4    // ...
5  },
6})

as shorthand for:

1export const createUser = extendType({
2  type: "Mutation",
3  definition(t) {
4    t.field('createUser', {
5      type: SomeType
6      resolve() {
7        // ...
8      }
9    })
10  }
11})

You can also use it with a function as the first argument, which will pass the t provided to the definition block, especially useful when using with the connection plugin:

1export const usersQueryField = mutationField((t) => {
2  t.connectionField('updateUsersList', {
3    type: SomeType,
4    resolve() {
5      // ...
6    },
7  })
8})
