The auto-tracing feature for requirejs/systemjs is now in a decent state for broader testing. I appreciate if you are interested to help to polish this feature.
The idea is to make bundler semi-transparent, we don’t enjoy thinking/fighting it. So you can focus on what you want to focus: your app.
The second post in the PR is all you need to read for testing it. Please report both failures and success, thx very much!
