[jira] Commented: (TAP5-73) JavaScript libraries should be
automatically packed/minimalized
[ https://issues.apache.org/jira/browse/TAP5-73?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12659433#action_12659433 ]
Martin Reurings commented on TAP5-73:
-------------------------------------
A built-in feature set such as this has the potential of a negative effect on real high-performance websites:
- Packing Javascripts may cause scripts that could have been cached client-side to get reloaded numerous times.
- Packing Javascripts may cause unneeded Javascript to get sent (and parsed) numerous times
- If T5 stays responsible for supplying what are essentially 'static' files these cannot be served from a different server, which allows caching and could have a different bandwidth allowance (this is already a problem and would get even worse).
- Packed/Compressed Javascripts are almost impossible to debug properly.
I'm quite certainly missing some more negative side-effects, but these feel likel enough to make my point. Features like these are great to have in a framework, but must be disabled by default, in my humble opinion. Also, I have to agree with some of the previous posters in stating, this should be fixed at build-time not take CPU and memory at run-time.

> Project: Tapestry 5
> Issue Type: New Feature
> Affects Versions: 5.0.15
> Reporter: Howard M. Lewis Ship

> Tapestry should catch downloads of JavaScript libraries, and should "pack" the JavaScript ... remove comments and unecessary whitespace. I believe Dojo has a library to do this, it may even shorten variable names (!).
> A smart implementation of this would manage to cache the compressed JS, and notice when the uncompressed version changed.
