static/styles/scss/portico.scss is now compiled by webpack
and supports SCSS syntax.
Changed the server-side templates to render the portico-styles
bundle instead of directly requiring the portico stylesheet. This
allows webpack to handle stylesheet compilation and minification.
We use the mini-css-extract-plugin to extract out css from the
includes in webpack and let webpacks production mode handle
minification. Currently we're not able to use it for dev mode
because it does not support HMR so we use style-loader instead.
Once the plugin supports HMR we can go on to use it for both
dev and prod.
The downside of this is that when reloading pages in the development
environment, there's an annoying flash of unstyled content :(.
It is now possible to make a change in any of the styles included
by static/styles/scss/portico.scss and see the code reload live
in the browser. This is because style-loader which we currently
use has the module.accept code built-in.
This commit fixes hot module replacement in webpack. To do this
we open port 9994 used by webpack to communicate between browser
and devserver. The attempts to forward the proxy from 9991 failed
so the last resort was to open up the webpack port.
It also removes an uncessary plugin in the webpack config and moves
the --hot flag to tools/webpack.
Update the config file to show slightly more information while
compiling webpack. Also decreased the time webpack waits before
recompiling in order to speed up HMR.
Changed the devtoool setting for development from 'eval' to
'cheap-module-eval-source-map' as it has better support for
breakpoints in Google Chrome and the difference is time is
negligible at the number and size of files currently being
consumed by webpack. This stragtegy can be reviewed in the
future as the size of files grows or Chrome adds better
support.
Upgrade webpack to latest version at the time of authoring. This
involves upgrading webpack version and its loaders to compatible
versions. It also involved editing tools/webpack to use the
executable for webpack-cli instead because of a change in how the
webpack package wants you to handle shell execution.
It also fixes the confugration for TypeScript in the webpack config
as that was previously broken. Including TypeScript files in JS
files compiled by webpack now works.
