Browser Builds

@prescott/geo-pattern provides browser builds.

All browser builds require Promise, Map, Set, and TextEncoder. You should polyfill missing features if you need to support legacy browsers.

Currently, There are four types of Browser Build.

Type	Path	Notes
Default (CommonJS)	dist/browser	Use this build if you're using bundler like Webpack.
ES5 (UMD)	browser/es5	Use this build if you want to support legacy browsers (e.g. IE 11)
ES6 (UMD)	browser/es6	Use this build if you want to support modern browers only
Native (UMD)	browser/native	Use this build if you want to support cutting-edge browsers only
