extendType

extendType

Defines a way to incrementally build types, by "extending" a type from multiple locations in a project. Useful in situations where you have types split across multiple domains, each of which should add fields to a single type (like the "Query" root).

1export const AddUserById = extendType({
2  type: 'Query',
3  definition: t => {
4    t.field('userById', {
5      type: 'User',
6      args: { id: intArg('id of the user') },
7      resolve: (root, args, ctx) => ctx.user.getById(args.id),
8    })
9  },
10})

14export const AddPostById = extendType({
15  type: 'Query',
16  definition: t => {
17    t.field('postById', {
18      type: 'Post',
19      args: { id: intArg('id of the post') },
20      resolve: (root, args, ctx) => ctx.post.getById(args.id),
21    })
22  },
23})

A similar extendInputType is available for extending input types.
