Describe the Bug

Created a new project:

npx create-payload-app@beta --use-npm

Loaded the admin panel and checked the network traffic. Saw that the not-found.js is 3 MB in size and therefore the largest downloaded file in dev mode. I guess Next.js bundles a lot of thing in this file. Please check why the not-found page is that large.

Sizes of other files:

• main-app.js: 1.6 MB
• layout.js: 2.6 MB
• not-found.js: 3.0 MB

After building the file is still quite large on first load but much lower than in dev mode:

Route (app)                              Size     First Load JS
┌ ○ /_not-found                          904 B          89.5 kB

  ├ chunks/fd9d1056-e7758cab2dfefddb.js  53.5 kB
  └ other shared chunks (total)          3 kB

Next.js always loads the not-found file in dev model. This large file could be responsible for higher startup times.

This should be the not-found page:

https://github.com/payloadcms/payload/blob/beta/packages/next/src/views/NotFound/index.tsx

@cbratschi on my end the built page.js file is 3 KB, not 3MB. This is after running npm run build and looking at .next/server/app/_not-found/page.js:

Served, it's less than 1B (same as you've pictured above):

And running dev mode, my not-found page is only 3.1kB:

If you can provide some clearer reproducible steps we can look into this further.

I created a fresh installation with:

npx create-payload-app@beta --use-npm

In my case the downloaded not-found.js was 3 MB, not the HTML page. This data gets loaded by the first request in dev mode. I am not accessing a missing page, just the Payload admin route.

Will try it again using the latest Payload beta.

Here are all the steps performed:

• npx create-payload-app@beta --use-npm
  • create-payload-app@3.0.0-beta.30
• cd project folder
• npm run dev
• Open http://localhost:3002/admin (or whatever port is being used)
• Check developer console

Sorted by file size:

Still getting a 3 MB not-found.js file:
