tRPC Adapter for Azure Functions v4

Only Support tRPC 10

This project provides an adapter for integrating tRPC (TypeScript RPC) with Azure Functions v4. The adapter simplifies the process of setting up type-safe and efficient APIs using TypeScript and tRPC within the Azure Functions environment.

Installation

npm install trpc-azure-functions-adapter

Usage

1. Create a trpc.ts file

// filename: `src/trpc.ts`

import { AzureFuncContextOption } from 'trpc-azure-functions-adapter';
import { inferAsyncReturnType, initTRPC } from '@trpc/server';

export function createContext({ context, request }: AzureFuncContextOption) {
  return {
    context,
    request,
  };
}

const t = initTRPC.context<typeof createContext>().create();

const publicProcedure = t.procedure;

export const appRouter = t.router({
  greet: publicProcedure
    .query(({ input, ctx }) => {
      console.log(ctx.request.params);

      return `Greetings, `;
    }),
});

export type AppRouter = typeof appRouter;

2. Create an Azure Functions entry file, e.g., main.ts

// filename: `src/main.ts`

import { createAzureFunctionsHandler } from 'trpc-azure-functions-adapter';
import { appRouter, createContext } from './trpc';
import { app } from '@azure/functions';

app.http('trpc', {
  methods: ['GET', 'POST'],
  authLevel: 'anonymous',
  route: 'trpc/{*proxy}',
  handler: createAzureFunctionsHandler({
    router: appRouter,
    createContext,
  }),
});
