README
A suite of polyfills supporting the Web Components specs:
Custom Elements: allows authors to define their own custom tags (spec).
HTML Imports: a way to include and reuse HTML documents via other HTML documents (spec).
Shadow DOM: provides encapsulation by hiding DOM subtrees under shadow roots (spec).
This also folds in polyfills for MutationObserver
and WeakMap
.
Releases
Pre-built (concatenated & minified) versions of the polyfills are maintained in the tagged versions of this repo. There are two variants:
webcomponents.js
includes all of the polyfills.
webcomponents-lite.js
includes all polyfills except for shadow DOM.
Manually Building
If you wish to build the polyfills yourself, you'll need node
and gulp
on your system:
- install node.js using the instructions on their website
- use
npm
to install gulp.js:npm install -g gulp
Now you are ready to build the polyfills with:
# install dependencies
npm install
# build
gulp build
The builds will be placed into the dist/
directory.
