No node entry point after `npm run build` in Next 15

[split rock]

why isn't npm run build showing an entry point for next 15, it should be something like node .next/server.js or node .next/server/index.js or something. But the output is just:

 my-app git:(main) npm run build

> [email protected] build
> next build

by default, it expects you to start the thing by next start.

if you want an entry point and a standalone folder that you can copy to any machine to deploy the app there, you can use standalone output: https://nextjs.org/docs/app/api-reference/next-config-js/output#automatically-copying-traced-files

[split rock]

the plan is to run it on my machine locally it's a utility project for my personal use

[glad geyser]

yeah then just next start, if not, standalone output is still a feasible option, you have a server.js that you can simply node it

[split rock]

I am asking for the "node" entry point. e.g. in Nuxt the node entry point is here: .output/server/index.mjs and you run it like node .output/server/index.mjs

Where is it in Next 15?

[split rock]

Where do I have server.js file? Can't find it anywhere in the final build.

[glad geyser]

yeah i know and i've been telling you to use standalone output, then it will be available in the final build

are you using output: "standalone"?

[split rock]

I am not familiar with this setup.

[glad geyser]

go read the link i provided above

[split rock]

is it somewhere in docs?

ok, thanks. Do you know why it isn't default option?

[glad geyser]

well... i don't know, honestly. i'm not part of the team

[split rock]

ok, now I have the server.js file in .next/standalone/server.js but the image links and css is broken 😭 I run it via: node .next/standalone/server.js

[split rock]

Any idea how to fix that?

Why isn't server.js picking up the images and css?

[glad geyser]

static assets are not served by default because most of the times you would want to move them to a CDN and serve them there instead

to serve them you just need to copy .next/static to .next/standalone/.next/static

i just tested in a nextjs app i have and it works fine

[ornate arch]

https://nextjs.org/docs/app/building-your-application/configuring/custom-server

I think this would work

[split rock]

Thanks, I copied it there and now I have this:

But Images are still missing 😭

[glad geyser]

what are the image URLs?

if they are the images in public folder, you need to copy it to the standalone folder too for the same reason

Additionally, a minimal server.js file is also output which can be used instead of next start. This minimal server does not copy the public or .next/static folders by default as these should ideally be handled by a CDN instead, although these folders can be copied to the standalone/public and standalone/.next/static folders manually, after which server.js file will serve these automatically.

[split rock]

Thanks! Finally it works after copying public/ folder to standalone/ 😉
