This adds a setting to disable the running of
babel-loader
on dependencies.Adding
babel-loader
on dependencies significantly impacts build time. The impact of this can be up to an extra minute.This PR reads the
COMPILE_DEPENDENCIES
environment variable.true
then compile dependencies as is done now.babel-loader
for dependencies.This is adding more configuration, and may not be in line with the direction of CRA (less config), but it could help people experiencing high build times who know their dependencies do not contain code breaking in their target browsers.
