compiler

Is this a regression?

Yes

Description

This worked in 12.1.3

We are compiling a component that wraps Stripe's Element. It takes quite a bit of custom styling.

SCSS looks like this:
.connect-button {

It appears there are two problems here.

  1. There is an error which is being shown during the JS optimization phase. Error: Optimization error [936.cf7797927c7f989bd40d.js]: Error: Transformation map 1 must have exactly one source file. Would you please share a reproduction of this?
  2. The second errors appears to be related to the components style bundle budgets. It appears that for this particular case the size of the css of the component regressed from 12.27 kB to 23.49 kB. The size regression comes from the fact that the previous minifier (cssnano) minfiied inlined PNGs. This was more of un-expected side-effect of using cssnano. In general we recommand against using inlined resources and instead opt for external assets to reduce bundle size and load assets lazily when needed.

I created a repo that I thought would recreate the error here:
https://github.com/bjornharvold/issue21508

Unfortunately it just errors out as expected. The only difference in this repo is that I didn't make it an Nx workspace.

The errors are related. I get the stacktrace after every component with a budget warning or error.

For now I will try to fix my budgets and see how that goes.

@bjornharvold, I am unable to replicate the Optimization error which the reproduction provided.

Correct, I mentioned as much in my last comment. Still looking into it on my end. Will point to that repo again when I think I found it.

@bjornharvold

Quick update - I increased budget sizes so warnings and errors would go away. The stacktrace did not go away and the build still fails -> so they are not related... just happening around the same time in the build process I gather.

Regarding the PNG optimisation I was incorrect. The problem appears that in the stylesheet provided there are a number of duplicate rules, which the new optimizer doesn't dedupe.

Increasing the budgets is not enough, you have another error Error: Optimization error [936.cf7797927c7f989bd40d.js]: Error: Transformation map 1 must have exactly one source file. This error is caused during sourcemap merging during the JavaScript optimization phase .

@bjornharvold

@alan-agius4 This style code came straight from the fine fellows at Stripe. Now that I look at it, it definitely looks like there is some duplicate code in there. I actually don't know why they have identical rules with different background images. Or, identical @media screen rules.

Interesting part is why does my example repo here not break but my real repo does break? This is where the error is after all.

Will fix the stylesheet rules and try building again.

@alan-agius4

The optimization exception is not related to CSS.

It is caused by an issue when merging JavaScript sourcemaps for 936.cf7797927c7f989bd40d.js. Potentially it might be caused by a dependency. Unfortunately, without a reproduction or private access to the project it's hard to tell what is happening.

@bjornharvold
Copy link
Author

Yes you are right. Cleaning up the CSS had no effect. I cannot find where 936.cf7797927c7f989bd40d.js is located after the build fails so I cannot open it to take a look to see what's in there. Also --verbose also didn't help.

Anything else I can try on my end?

We can give you private access to the company repo @alan-agius4.

You can run the build with --named-chunks which will emit the file name instead of an Id for lazy chunks.

Share the repo privately would be great!, let me know what you need.

@bjornharvold

Could use named chunks. Just saying I don't know where it's being created because the app fails so there are no output files.

My email is [email protected]. Shoot me an email and I will give you access to our staging server with Visual Studio Code open and a terminal to play with.

I've started a build on staging that will take a couple of hours. When you connect, you'll be able to see the failure.

Test repo updated. I added import { JwBootstrapSwitchNg2Module} from 'jw-bootstrap-switch-ng2'; to AppModule and lo and behold. It breaks!

The root cause appears to be that these libraries have inline sourcemaps. As an interim workaround you can enable vendor sorucemaps.

See: https://angular.io/guide/workspace-config#source-map-configuration

I'll be working on a fix to address this soon.

@bjornharvold, thanks a lot for helping us getting to the bottom of this.

alan-agius4 added a commit that referenced this issue Aug 6, 2021
…when vendor sourcemaps is disabled.

Not removing inline sourcemaps when vendor sourcemaps is disabled causes an issue during the JS optimization sourcemap merging phase.

```
Optimization error [936.cf7797927c7f989bd40d.js]: Error: Transformation map 1 must have exactly one source file.
```

When vendor sourcemaps is disabled we are not interested into the said sourcemaps so now we remove the inline sourcemap.

Closes #21508
