Support fastboot

[mabab]

Is there any way to support fastboot?
After install the ember-cli-fastboot package to test-app, I get an error every time I render a page.

Error occurred:

• While rendering:
  -top-level
  application

There was an error running your app in fastboot. More info about the error:

hmm is test-app part of a V2 addon? We do have Fastboot present in the project where I used this so it seems supported at least in some contexts.

Maybe I didn't explain it correctly. I just intentionally added ember fastboot locally for test-app to emulate the error I get in the project with fastboot. It seemed to me that test-app is the perfect example to pass on to you.

In short, I have a fastboot application that cannot render the page on the server due to an error if I add <style> to the component and I get an empty page without the component, but in the browser the rendering is normal since the initialization on the client is already working.

In cardstack, I found a disabled ember fastboot for the ember serve
https://github.com/cardstack/boxel/blob/main/packages/host/package.json
Is it necessary for work?

reproduce the problem in your own empty project https://github.com/mabab/test-scoped-css-with-fastboot

Thanks for the reproduction repository, when I run it I do see that error as well as this one above it:

There was an error running your app in fastboot. More info about the error:
 ReferenceError: document is not defined
    at insertStyleElement (webpack://test-scoped-css/../../.pnpm/style-loader@2.0.0_webpack@5.90.3/node_modules/style-loader/dist/runtime/injectStylesIntoStyleTag.js?:93:15)

I’m not sure how to proceed here but I’ll look more into this.

[gossi]

I see it working for me with ember-cli-fastboot but saw the ReferenceError: document is not defined when using it in combination with prember.

I couldn't find a proper trace, only the stacktrace to prember build call. But yours above reveals style-loader at v2.0.0 which does use document

A pnpm why reveals, that ember-auto-import uses style-loader@v2.

Oh v4.0.0 is the current version of style-loader at the time of writing, they also do use document for their runtime. I think it comes down to that usage.
