Happypack, migrate to babel-preset-env and inline babelrc 🏎 #327

Closed pirelenito closed 7 years ago

pirelenito commented 7 years ago

Besides enabling Happypack to improve the build speeds, this PR does three big changes:

It takes back the control of the babelrc file from the user, and instead holds this configuration as part of Sagui
Replaces the custom babel-preset-sagui with babel-preset-env and babel-preset-stage-3 for more stability and polyfill bundling optimization
It also allows Webpack2 to perform Tree Shaking

This might pose some migration work to our users, but with the benefit of using more stable language features.

I just remember we need to strip Flow type definitions by adding another babel plugin.
