Unable to find next/dist/server/lib/render-server-standalone in next.js 14

Unable to find next/dist/server/lib/render-server-standalone in next.js 14. Iam migrating my code from next.js 13 to next.js 14, which is giving errors in my server.js

What did you use from that file? or how did you use it? it was never part of the public API I guess, so if it was moved between versions, it is your responsibility to figure out what to do to continue using your app.

I was using it in server.js for Deployment with docker

This is the server.js I am using currently
const http = require("https");
const path = require("path");
const { createServerHandler } = require("next/dist/server/lib/render-server-standalone");
const fs = require("fs");

const dir = path.join(__dirname);

process.env.NODE_ENV = "production";
process.chdir(__dirname);

// Make sure commands gracefully respect termination signals (e.g. from Docker)
// Allow the graceful termination to be manually configurable
if (!process.env.NEXT_MANUAL_SIG_HANDLE) {
process.on("SIGTERM", () => process.exit(0));
process.on("SIGINT", () => process.exit(0));
}

let handler;

const currentPort = parseInt(process.env.PORT, 10) || 3000;
const hostname = process.env.HOSTNAME || "localhost";
const keepAliveTimeout = parseInt(process.env.KEEP_ALIVE_TIMEOUT, 10);

const sslOptions = {
key: fs.readFileSync("Path to key"),
cert: fs.readFileSync("path to certificate"),
};

const server = http
.createServer(sslOptions, async (req, res) => {
await handler(req, res);
})
.on("error", (err) => {
console.error(err);
res.statusCode = 500;
res.end("Internal Server Error");
});

if (!Number.isNaN(keepAliveTimeout) && Number.isFinite(keepAliveTimeout) && keepAliveTimeout >= 0) {
server.keepAliveTimeout = keepAliveTimeout;
}
server.listen(currentPort, async (err) => {
if (err) {
console.error("Failed to start server", err);
process.exit(1);
}

handler = await createServerHandler({
port: currentPort,
hostname,
dir,
});

console.log("Listening on port", currentPort, "url: http://" + hostname + ":" + currentPort);
});

I did a bit of digging around and found:

• f57eecd
• ac62406
• 1398de9

Which seem to suggest that createServerHandler is gone.

I think you can use const { startServer } = require('next/dist/server/lib/start-server') rather... look at this part here:

That didn't work either for me. Can you suggest a way as an alternative for the attached server.js

[icyJoseph]

Not really 😄

Maybe look at this? https://stackblitz.com/edit/github-6mzuef?file=server.js
