tRPC - Nest.JS Adapter
- Allows you to use Trpc with Nest.JS.
- Allows you to use request scoped Nest.JS providers
- Allows you to use Nest.JS's great module system
Feature support
I don't use all of the features tRPC has :/
Both queries and mutations work.
I haven't tested subscriptions yet.
How
See the example folder in this repo, but briefly
yarn add trpc-nestjs-adaptermain.ts
// Standard nest.js main.ts
import { NestFactory } from '@nestjs/core';
import { NestExpressApplication } from '@nestjs/platform-express';
import { AppModule } from './app.module';
async function bootstrap() {
const app = await NestFactory.create<NestExpressApplication>(AppModule);
await app.listen(3000);
}
bootstrap();app.module.ts
import { Module } from '@nestjs/common';
import { TrpcModule } from 'trpc-nestjs-adapter';
import { rootRouter } from './trpc/root-trpc.router.ts';
import { createContext } from './trpc/create-context.ts';
@Module({
imports: [
AModule,
TrpcModule.forRoot({
path: '/trpc',
router: rootRouter,
createContext,
}),
],
})
export class AppModule { }Inside of your procedures
export const exampleMutation = trpc.procedure
.input()
.mutation(async ({ ctx })=>{
const nestService = await ctx.resolveNestDependency(SomeNestService);
await nestService.someServiceMethod()
})Note
The package is marked alpha for a reason, but mostly It's not documented very well.
If/When/As the package gains traction I'll improve the example & related docs.
