polycat — handy polyfills, concatenated together
polycat is a javascript bundle that can teach old dogs new tricks
slap polycat onto any page
<script src="https://raw.githubusercontent.com/chase-moskal/polycat/master/polycat.js"></script>install polycat properly with npm
npm install polycat<script src="node_modules/polycat/polycat.js"></script>
polycat includes these polyfills
- array.find
- es6-promise
- whatwg-fetch
but you should make your own honest bundle
polycat probably has stuff you don't need, or doesn't have things you do need — check out the build script, and consider doing something similar in your own project's build routine — construct your own custom polyfill bundle
polycat is more like an example collection of polyfills known to work the good old fashioned global way (unlike "ponyfills" as they are called)
