Defining a JWT Structure

The authentication module works best if you define the structure of JWTs - JWT validation will include checking that JWTs match the structure defined via class-validator.

src/user/dto/jwt-payload.ts

import { Role } from "acl"; (1)
import { IsString } from "class-validator";

export class JWTPayload {

  @IsString()
  sub: string;

  @IsString({
    each: true,
  })
  roles: Role[];

}

1	This example uses roles defined in a ACL package, created with Formulaic’s ACL Utilities.
