Declarative Wrapping (null/list)

Declarative Wrapping

The declarative wrapping plugin adds the pre-0.19 APIs of list: true | boolean[], nullable: boolean, and required: boolean on field & argument definitions.

To install, add the declarativeWrapping to the makeSchema.plugins array, along with any other plugins you'd like to include:

1import { makeSchema, declarativeWrappingPlugin } from 'nexus'
2
3const schema = makeSchema({
4  // ... types, etc,
5  plugins: [
6    // ... other plugins
7    declarativeWrappingPlugin(),
8  ],
9})

You can now use the object style APIs on any args & field definitions.

1export const User = objectType({
2  name: 'User',
3  definition(t) {
4    t.string('someNullField', {
5      nullable: true,
6    })
7    t.string('someRequiredField', {
8      nullable: false,
9      resolve: () => 'Some Field',
10    })
11    t.string('someList', {
12      list: true,
13      resolve: () => [],
14    })
15    t.string('someListOfLists', {
16      list: [true, true],
17      args: {
18        int: intArg({ required: true }),
19      },
20      resolve: () => [],
21    })
22  },
23})

If you have migrated to the new chaining / wrapping APIs and would like to disable the typings and make usage a a runtime error, add declarativeWrappingPlugin({ disable: true }).
