Subject [jira] [Commented] (RANGER-2220) Admin UI loads slowly because of many small JavaScript files
Date Wed, 19 Sep 2018 21:07:00 GMT

Csaba Koncz commented on RANGER-2220:
-------------------------------------

Here is the promised patch: [https://reviews.apache.org/r/68770/]

It is quite large as it includes RequireJS optimizer source.

Unfortunately I could thoroughly test it only on version 0.7.0 (the one included in HDP 2.6.5).

For the master branch I only loaded the UI and checked that there are no RequireJS errors
(did not have a compatible backend to check the functionality).

> The Admin UI web page loads slowly after login (~10 seconds or more, depending on network
conditions)
> This is due to the ~140 small JavaScript files that need to be downloaded before the
UI can be presented to the user.
> Compressing/concatenating (=minifying) JS resources and downloading them in a single
step can improve the situation.
> Prototyped a solution for version 0.7 (using RequireJS Optimizer), will try to port it
to the master version.
