API

• WebComponents.load(globExpr)
• WebComponents.engine(type, fn)
• WebComponents.register(name, prototype)
• WebComponents.render(path|content, commonData)

  Every components in file receive commonData.

Template Note You Must Know

First DOM parse, then template render, so do not break the DOM.

<img src="{{#if ("true")}}{{src}}{{/if}}"> 

DOM parse above string as:

<img src="{{#if (" true")}}{{src}}{{="" if}}"="">

You should write like:

<img src="{{#if ('true')}}{{src}}{{/if}}">
