A lightweight polyfill lib.

Package Exports

  • hpolyfill

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (hpolyfill) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

HPolyfill

This is a lightweight(less than 10KB) polyfill lib which includes some common polyfills.

Usage

Just simply include one of the following script tags in your HTML to get the polyfills:

<!-- via jsdelivr -->
<script type="text/javascript" crossorigin="anonymous" src="https://cdn.jsdelivr.net/npm/hpolyfill@latest/dist/index.js"></script>
<!-- or via unpkg -->
<script type="text/javascript" crossorigin="anonymous" src="https://unpkg.com/hpolyfill@latest/dist/index.js"></script>

By the way, as a polyfill lib, this lib should be loaded first in most cases.
