This doesn’t have much impact on resulting JS size, but it will
hopefully make merge conflicts much less frequent.
The CSS growth is a little higher (6.5% increase in size) but is not
material.
If this materially reduces the number of merge conflicts we have, by
letting the git merge tools resolve some dist file mergers, I think it
would be worth it.
Some example changes in file size:
bundle.js 290K -> 301K
vendor.js 1,325K -> 1,321K
bundle.css 628K -> 669K
* Rename bundles (prep for webpack optimisation)
This might or might not reduce the overall repo size,
because git can combine similar chunks in the newly generated files
* Optimise webpack build time
Consolidates bundles, since a separation of bundle-framework.js vs. bundle-legacy.js
vs. bundle-lib.js no longer makes sense - they're all loaded upfront anyway,
since we'll be introducing more react-powered logic alongside the "legacy" JavaScript.
By consolidating into fewer bundles, we give the optimisation scripts (UglifyJS)
more options to reduce the overall file size.
The main motivation for a vendor.js is to shorten rebuild times:
Most active development is happening in files required through bundle.js.
This commit drastically reduces the rebuild time for those changes (15s to 4s).
