tRPC Express server with Next.js
As much as I hate this, I am required to use Express for back-end and Next.js for front-end.
I have two Node.js projects, an Express server and a Next.js client.
I did a minimal setup on the back-end side using the Express adapter and it is working fine when i try to hit an endpoint on the browser.
index.ts:
Now when I try to use the trpc client on Next.js I get a TypeError.
What I did once I created the Next.js client, is running npm link to be able to import my appRouter.
Here is my utils/trpc.ts:
```js
import { httpBatchLink } from "@trpc/client";
import { createTRPCNext } from "@trpc/next";
import { appRouter } from "trpc-express";
function getBaseUrl() {
if (typeof window !== "undefined") return "";
if (process.env.VERCEL_URL) return
https://${process.env.VERCEL_URL}`;
if (process.env.RENDER_INTERNAL_HOSTNAME)
return http://${process.env.RENDER_INTERNAL_HOSTNAME}:${process.env.PORT}
;
return http://localhost:${process.env.PORT ?? 3000}
;
}
export const trpc = createTRPCNext<typeof appRouter>({
config(opts) {
return {
links: [
httpBatchLink({
url: ${getBaseUrl()}/api/trpc
,
async headers() {
return {};
},
}),
],
};
},
ssr: false,
});

If any one can provide me with insight regarding this issue, I'd appreciate it.4 Replies
is react installed?
Yes.
It's Next.js. React comes installed by default.
hard to help without a repro then
this might be inaccurate but maybe it can help
I also have a few apps using an express + nextjs setup, but I am not using the Next adapter for trpc. Instead I use the base react adapter.
Here's an example, although its from an expo project. But the client setup is exactly the same across all of my projects:

Now, the big issue with this is that I haven't been able to get it to work inside server components, so if you're working with the app router it might not be what you're looking for.
I am currently trying to get another express/nextjs project to work. I'll make sure to get back to you in case I am successful.
Best of luck!
