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 |
