Unable to deploy express.js project: EADDRINUSE: address already in use

Hello, I was trying to deploy a new service consisting of a express.js server and was having trouble getting it to deploy. I have another service that is also using express that is working perfectly fine, and I have this one setup in the exact same way (using the PORT env to listen on) but this one seems to have trouble listening on any given port. I have also tried specifying 0.0.0.0 with no luck. Thanks in advance! Error log:

Now listening at http://localhost:8059!

Express server code:

const port = process.env.PORT || 3000;

import express from 'express';
import { handler as ssrHandler } from './dist/server/entry.mjs';

const app = express();
app.use(express.static('dist/client/'));
app.use((req, res, next) => {
    ssrHandler(req, res, next, locals);
});

app.listen(port, () => {
    console.log(`Now listening at http://localhost:${port}!`)
})

const port = process.env.PORT || 3000;

import express from 'express';
import { handler as ssrHandler } from './dist/server/entry.mjs';

const app = express();
app.use(express.static('dist/client/'));
app.use((req, res, next) => {
    ssrHandler(req, res, next, locals);
});

app.listen(port, () => {
    console.log(`Now listening at http://localhost:${port}!`)
})

Solution:

can you start your astro app with the node adapter instead of trying to serve it with express

have you set a custom start command anywhere?

oog•9mo ago

Yeah, in the project I have the build command set to npm install; npm run build and start command to node start.js

Brody•9mo ago

remove both build and start commands from the service settings. set your start script in your package.json to node start.js

oog•9mo ago

Still the same error unfortunately

Brody•9mo ago

build logs please https://bookmarklets.up.railway.app/log-downloader/

Brody•9mo ago

and deploy logs too?

Deploy log is just this repeated

Before removing the custom start/build commands the npm WARN config production Use --omit-dev instead. line was not there

oog•9mo ago

oh my god. I forgot to switch mode in astro.config.mjs to middleware instead of standalone, thats why the address was already in use unbelievable i knew it was something stupid, thank you so much for your help i was truly stumped

Brody•9mo ago

yeah i knew astro was trying to run a server too, thats why i asked you to just use its server instead of express

oog•9mo ago

worked locally though, so strange again thank you so much

Brody•9mo ago

no problem!
