Terser discussion of working around pure_getters

This was one of the changes in version 9 where server production code is minified, one of the main reasons behind this is to speed up server cold starts and reduce deployment times. What I suggest is to generate sourcemaps and attach them, which will provide a better debug experience.
This is what I'm doing for Sentry, which works reasonably well (shipping the source maps to Sentry in CI), but I'm also shipping server-side logs to an ELK stack - with minified code those would show meaningless stack traces.
One way around could be to embed the source maps into the prod container & apply those on the error stack traces, but I'd rather not have that kind of logic running on errors, in order to ensure those are properly reported (and not swallowed), plus that'd defeat a bit the goal of reducing deployment times.
Not sure how others have solve these problems as the cold starts time & memory usage are indeed quite large (especially when running a 30+ locales app), but for the moment I'd still be interested by a proper way to turn off server-side code minification (a rollup pass or anything that does not make the code unreadable is fine though).
Just a heads up that we kicked off a community voting process for your feature request. There are 20 days until the voting process ends.
Find more details about Angular's feature request process in our documentation.
Thank you for submitting your feature request! Looks like during the polling process it didn't collect a sufficient number of votes to move to the next stage.
We want to keep Angular rich and ergonomic and at the same time be mindful about its scope and learning journey. If you think your request could live outside Angular's scope, we'd encourage you to collaborate with the community on publishing it as an open source package.

Either having several levels (e.g.
