In this article, we’ll build a type-safe tRPC CRUD API with Next.js, PostgreSQL, and Prisma. This tRPC example in Next.js will showcase how to use tRPC on the backend and later we will consume the API on the frontend app.
In the auth.controller.ts file I see a lot of TypeScript errors that say:
"Property 'req' does not exist on type 'Promise<{ req: NextApiRequest; res: NextApiResponse; user: null; } | { req: NextApiRequest; res: NextApiResponse; user: { ...; }; }>'."
It likely got to do with the fact that this is a Promise.
In user.service.ts another type error:
"Property 'user' does not exist on type 'Promise<{ req: NextApiRequest; res: NextApiResponse; user: null; } | { req: NextApiRequest; res: NextApiResponse; user: { ...; }; }>'."
And in user.service.ts another one:
"Type 'Partial' is not assignable to type 'UserWhereInput'.\n Types of property 'posts' are incompatible.\n Type 'PostCreateNestedManyWithoutUserInput | undefined' is not assignable to type 'PostListRelationFilter | undefined'.\n Type 'PostCreateNestedManyWithoutUserInput' has no properties in common with type 'PostListRelationFilter'."
Running the app I'm unable to go past the login screen.
Register and upload works
Also maybe it's time to update the tutorials to tRPC 10 and Next.js 13 and fix some of the mistakes in the blog posts?
