Dockerfile in Tubrorepo
Hi I have a Turborepo where I have a nextjs frontend “web” and an express backend “api” both connected through trpc (guess that’s obv). I’m kinda finding it difficult to create a docker image for this 🫠 has anybody else done this before? Any example I could take a look at? Thanks!

Websocket is not defined error
I'm getting a "WebSocket is not defined error" on my next app connected to an express backend. Any idea what I'm doing wrong?
My server/index file is
import * as trpcExpress from "@trpc/server/adapters/express";
import { applyWSSHandler } from "@trpc/server/adapters/ws";
import express from "express";
import cors from "cors";
import { appRouter } from "./routers/_app";
import { createContext } from "./context";
import ws from 'ws'
const app = express();
app.use(cors({ origin: ["http://localhost:3000", "http://localhost:3001"] }));
app.use(
"/trpc",
trpcExpress.createExpressMiddleware({
router: appRouter,
createContext,
})
);
const server = app.listen(8000);
applyWSSHandler({
wss: new ws.Server({ server }),
router: appRouter,
createContext
})
My context file is
import { inferAsyncReturnType } from "@trpc/server";
import * as trpcExpress from "@trpc/server/adapters/express";
import { NodeHTTPCreateContextFnOptions } from '@trpc/server/adapters/node-http';
import { IncomingMessage } from 'http';
import ws from 'ws';
export const createContext = ({ req, res }: trpcExpress.CreateExpressContextOptions | NodeHTTPCreateContextFnOptions<IncomingMessage, ws>) => {
return ({
req, res
})
}
export type Context = inferAsyncReturnType<typeof createContext>;3 replies
