Merging Routers

Writing all API-code in your code in the same file is not a great idea. It's easy to merge routers with other routers.

Thanks to TypeScript 4.1 template literal types we can also prefix the procedures without breaking typesafety.

Working example

• Code at /examples/next-prisma-starter/src/server/routers/app.ts
• All code for posts living in a separate router and namespaced with post.

Example code

const posts = createRouter()  .mutation('create', {    input: z.object({      title: z.string(),    }),    resolve: ({ input }) => {      // ..      return {        id: 'xxxx',        ...input,      }    },  })  .query('list', {    resolve() {      // ..      return []    }  });
const users = createRouter()  .query('list', {    resolve() {      // ..      return []    }  });

const appRouter = createRouter()  .merge('user', users) // prefix user procedures with "user"  .merge('post.', posts) // prefix poosts procedures with "post."  ;
