Analyze runtime bundle size and track its changes over time

[kripod]

Motivation

A significant amount of code gets compiled by treat, which will not be part of the runtime. Also, only the OptimizedStyleInjector may get instantiated (besides NullStyleInjector) on the client side.

In addition to above, OptimizedStyleInjector and OptimizedRuleManager can be tree-shaken when no <StyleInjectorProvider> is used.

Is there a tool for analyzing production bundle sizes accurately, given the constraints above?

[kripod]

Using bundlesize is partly sufficient. Fuzzy matching may help ignoring files which are not included in the final bundle.

An idea might be to have a sample app which uses glaze and build it with each PR so we can track the impact of the changes on a final app. Similar to what nextjs does with https://github.com/zeit/next-stats-action
