fixes: CNVS-31779 [webpack] bundle file size
test plan:
* using webpack, look at the network panel in
the chrome developer console.
* the total ammount of javascript loaded for any
given page should be much less than before this commit
and about on par with what requireJS loads for the same page.
* use chrome network panel to throttle to "Regular 3G"
* from both a clean cache and a primed cache:
* make sure that the total time to render the page
is about on par with requireJS
first change: load webpack chunks from CDN
fixes: CNVS-32261
test plan:
* run `npm run webpack-production`
* check your page, it should load js files and chunks
from the same hostname the page is served from.
* now set a host: in config/canvas_cdn.yml
(for testing locally, I just set it to http://127.0.0.1:3000,
* restart rails and reload the page, now the scripts and
chucks should come from that new hostname
second change:include fingerprints in webpack bundle and chunk filenames
closes: CNVS-28628
with this change we don't need to run `gulp rev`
after running webpack and we can load both the bundle
and chunk files safely from the cdn, since they will
have content-based fingerprints so we can tell
browsers to cache them forever. (we set those
http caching headers in lib/canvas/cdn/s3_uploader.rb:53)
test plan:
* for both dev and production
* run `npm run webpack` (or `npm run wepack-production`)
* with a cdn configured in canvas_cdn.yml, run:
RAILS_ENV=<dev or prod> bundle exec rake canvas:cdn:upload_to_s3
* check to make sure that the page loads the webpack js,
that there are no errors, and it all came from the cdn
third change: properly handle moment locale & timezone in webpack
test plan:
(see application_helper_spec.rb)
* set a non-default user timezone, context timezone
and locale
* dates should show up in your timezone and and
the date helper strings should be in your language
better handling of moment custom locales
closes: CNVS-33811
since we now have hatian and maori, we need to do this in
a way that is not just a one-off for maori
test plan:
* set your locale to maori
* in webpack & requireJS make sure dates show up right
