This example uses gulp with gulp-rev and webpack with
webpack-assets-manifest to build the assets and generate the manifest. Refer
to the package.json, gulp tasks, and
webpack.config.js to see the specifics.
In this example, sprockets has been completely removed. Thus, there's no
more assets:precompile rake task, and in fact, there's no need to install
gems, load the rails environment, or even have ruby installed to compile
assets - the app's asset compilation is completely decoupled from rails! When
that coupling exists, changes to ruby code may affect assets, but when they're
completely separate, that's guaranteed to not be the case. Thus, we can easily
determine when it's unnecessary to recompile assets and use that to reduce the
overall build time.
