    - iOS Safari 12.?? (originally released 2018, last update 2019[3])

    So using Create React app this probably should have at least worked in iOS Safari.

    So this brings up the question of how far back should we support? Chrome 76 and iOS 12 are only a few years old (2018-2019). According to caniuse[4], Both Chrome 76 and Safari 12.1 have a usage of 0.07% so in order to support it you would need to change the ">0.2%" to ">0.06%". If your build process is already setup to use Babel+BrowsersList then it should be an easy fix of just changing values in the array and it should come at no cost to your development experience.





  • Manage list of supported browsers for your application in Angular

    This scenario is very easy to implement with browserslist-useragent-regexp package. This package along with browserlist (already provided by angular) enables us to query / cherry-pick browsers according to their version numbers.

    During development it's important to implement tooling that will actively lint the code you're writing, it'll tell you if there's a problem i.e. browserslist, eslint, stylelint.

What are some alternatives?

When comparing parcel and browserslist you can also consider the following projects:

vite - Next generation frontend tooling. It's fast!

esbuild - An extremely fast JavaScript and CSS bundler and minifier

Snowpack - ESM-powered frontend build tool. Instant, lightweight, unbundled development. ✌️ [Moved to:]
