WIP / Prototype (do not use in production)
Experimental support for using Nexus schema construction with decorator syntax. Currently requires decorators to be enabled, by either TS's experimentalDecorators: true, or using Babel's plugin-proposal-decorators
Provide a syntax to use the core of Nexus in decorator format, to de-duplicate domain models.
- Unable to auto-check / infer types - must be manually added
- Interfaces via inheritance
- Mix & match w/ regular Nexus definitions
- Guarding / auto-creating classes if we don't have that object type
- Auto isTypeOf for interfaces
- General construction
See the live example
import { nxs } from "nexus-decorators";
@nxs.objectType({
name: "Query",
})
class App {
constructor() {}
@nxs.field.list.type(() => User)
static users() {}
}
interface UserShape {
id: number;
firstName: string;
lastName: string;
}
@nxs.objectType()
class User {
constructor(record: UserShape) {
this.record = record;
}
@nxs.queryField(() => ({
type: User,
args(t) {
t.nonNull.string("name");
},
}))
static userByName(args, ctx) {
return ctx.findUserByName();
}
@nxs.mutationField(() => ({
type: User,
args(t) {
t.nonNull.string('name')
}
}))
static async createUser(args, ctx) {
return new User(await ctx.db.insertUser(args))
}
@nxs.field.id()
get id() {
return `User:${this.record.id}`;
}
@nxs.field.string()
get name() {
return `${this.record.firstName} ${this.record.lastName}`;
}
}Prints:
type User {
id: String
name: String
}
type Query {
users(): [User]
userByName(name: String!): User
}MIT
