Reopening #162: config.assets.debug = true still compiles everything into single CSS/JS files? #688

Reopening #162 which is not fixed with rails 5.2.0 and sprockets-rails 3.2.1

This is a bug with source map generation, but the idea is to generate only one asset in development with source maps pointing to the right source.

And the source map isn't working, as stated in #656 with Sprockets 4.

Hello! Thanks for opening up an issue. In order to move forwards with this issue I'll need an example app that reproduces the behavior (https://www.codetriage.com/example_app).

The semantic has changed a bit as far as I understand. You need to select a pipeline in debug mode. Please consult this patch, especially changes to file lib/opal/sprockets/assets_helper.rb:

https://github.com/opal/opal-sprockets/commit/6d9bc126675f27a1e2e37b50a747f349e599b320

By default it uses a "default" pipeline, which returns a concatenated file without source maps, you expect a "self" pipeline, which is without source maps, "debug" pipeline returns a concatenated file WITH source maps

Yes, it's true that it returns a single file, but with the more robust caching in 4.0 it works well enough in my experience.

I found also this issue in rails: https://github.com/rails/rails/issues/43203 The author created already an example app here: https://github.com/josh-m-sharpe/assets_test
