# Goals and basic feature support (as of august 2021)
#--------------------------------------------------------------------------
#
# The goal is to be able to safely, natively, bloat free, ship web features.
# The browser should have support for at the very least `ESM script tag`
# and `native ESM dynamic import` (ViteJS's default target).
#
# This following config should not settle for less than 90% overall browser
# coverage on browserslist.dev and caniuse.com.
# Forthemore support for the latest versions of the following browsers should
# be assured (based on https://gs.statcounter.com's worldwide browser market share) :
# - Chrome
# - Safari
# - Firefox
# - Edge
# - Samsung
# - Opera
# - Chrome For Android
# - Safari For IOS
#
# - https://caniuse.com/es6-module
# - https://caniuse.com/es6-module-dynamic-import
# - https://vitejs.dev/guide/build.html#browser-compatibility

supports es6-module and supports es6-module-dynamic-import


#--------------------------------------------------------------------------
# Minimum browser versions
#--------------------------------------------------------------------------
#
# Naive strategy to target browsers with full support for ES2021.
# Essentially targeting browsers with full support for `Private class fields`.
#
# Shorter Browserslist query : `supports private-class-fields`.
