Feedback on `--experimental-minify`

[GregBrimble]

If you spot a bug relating to the --experimental-minify feature, please describe below!

[Shadid12]

Hi I am encountering the following error when I run npx @cloudflare/next-on-pages --experimental-minify

ERROR: Unknown functions manifest version. Expected 2 but found 1.

My API route looks like this

// pages/api/hello.js

export const config = {
  runtime: 'experimental-edge',
}

export default function handler(req, res) {
  res.status(200).json({ name: 'John Doe' })
}

When I take out the runtime: 'experimental-edge', code block it builds.

[smol-honk]

I'm also getting this with no api routes. I have it globally set in my next.config.js though.

I am seeing the following issue:

I have configured our Pages deployments to use the commands described in this repo:

10:14:51.816 | Executing user command: npx @cloudflare/next-on-pages --experimental-minify

This could be a simple issue of not having updated Next? We've moved from Vercel with an existing application - you can see the PR here - NorfolkDev/nordevcon-website#110

[vbuser2004]

Experiencing the same output and failed build as @Illizian and @Shadid12 above.

Using:
Nextjs: 12.2.5
Node: 16.14.1

[jdddog]

I'm receiving the error below. Without the --experimental-minify flag it doesn't occur. Using Next.js version 13.0.6.

[Cherry]

It seems like --experimental-minify is actually inflating the build when simply duplicating pages from the initial create-next-app. Filed an issue about this and the general size output at #47.

[Stijn-B]

With our project (which was started from https://github.com/shadowwalker/next-pwa) npx @cloudflare/next-on-pages works without the --experimental-minifynode but when I add it there are 6 errors, all of which are just Unexpected "??"'. Looks like it's the same error as mentioned above: #2 (comment)

However Cloudflare Pages doesn't work, even without the --experimental-minifynode because of Error: Failed to publish your Function. Got error: Error: Script startup exceeded CPU time limit.. I can't figure out how to fix this yet but think it's unrelated to @cloudflare/next-on-pages

met the same error Error: Failed to publish your Function. Got error: Error: Script startup exceeded CPU time limit. when I deploy pages with prisma. Do you solve it?

[jdddog]

@Stijn-B and @shiyuhang0 I might have had the same problem when deploying to Cloudflare Pages. I was using the Direct Uploads feature though and it wasn't very forthcoming with a detailed error message, it just said "no deployment available".

[mattddean]

I updated the version of esbuild used by next-on-pages and got a more descriptive error message for the ✘ [ERROR] Unexpected "??" error.

With version 0.17.14 of esbuild, the error message is ✘ [ERROR] Cannot use "??" with "&&" without parentheses.

I suspect this may something to do with the fact that npx vercel build has already "built" the JavaScript files, seemingly without respecting the ?? and && rule, and so this error comes about trying to run esbuild on already built JS files. I wonder if there is a bug in what npx vercel build uses to build is JS files that produces JS that doesn't follow this ?? and && rule.

The issue can be reproduced by cloning this repo, checking out a commit and running the commands in the readme.

git clone git@github.com:mattddean/next-pages.git
cd next-pages
git checkout e5e8b258164e04053e86932093af77184a77d545

met the same error Error: Failed to publish your Function. Got error: Error: Script startup exceeded CPU time limit. when I deploy pages with prisma. Do you solve it?

@shiyuhang0 the startup cpu time limit is a different issue, we're aware of it and will soon provide a solution for it 🙂 (PS: but it might still happen if your app needs to perform lengthy operations when handling requests)

[dario-piotrowicz]

Closing the issue, thank you so very much!

Thank you so very much everyone for the valuable feedback! ❤️ 😄 ❤️

I'm closing this issue as we hope that experimental minification is somewhat stable and keeping a github issue around for it doesn't help us much in tracking issues with it.

Regarding the issues/bugs mentioned in this thread

The initial issues mentioned in this thread (by @Shadid12, @smol-honk, @Illizian and @vbuser2004) are hopefully/likely not present anymore (since we made improvement in those areas), I'll keep an eye out for them, but please if you want double check if those are still present and if they are please file bug reports for them 🙏

The issue created by @Cherry has already been addressed 🙂

Regarding the ?? issues mentioned by @jdddog, @Stijn-B, @shiyuhang0 and @mattddean, I imagine that that is still a problem so I have created a new issue for it: #151, I will look into that shortly (thanks a lot for reporting it!)

Discussion

Lastly I have created a discussion for the experimental minification: #152 so that we can keep receiving valuable inputs on it, but I hope that that will only be used for ideas of improvement on the core minification strategy and the like, and actual bugs/feature requests will be created via standard issues (which I believe are easier to track and address)
