wcpack - webcomponent-pack

wcpack is a utility for packaging WebComponents are an emerging standard that makes it easy to create reuseable components for the browser. Just imagine creating your own tags that are simple for others to use as adding the <my-tag></my-tag> to their page.

Need

As great as WebComponents are, they are best packaged as a single file, and that isn't necessarily the most convenient way to develop thing. This is where wcpack comes in; it allows you to develop your components as a single file, and then package them together for distribution.

wcpack will take all of your component's HTML, JavaScript, and CSS files and concatenate them together and package them as a single .html file.

Installation

To install the command line tool:

npm install -g wcpack

To install as an node module in your own project:

npm install wcpack

Command line

The command line tool is where you will package your components together. A typical usage:

Let's say you have a directory structure with these files:

tabs.html

<element name="tabs" constructor="TabsHTMLElement">
  <section>
    I'm tabs!
  </section>
  <script src="tabs.js"></script> 
</element>

tabs.js

if(this !== window) {
  var section = this.querySelector('section');
 
  this.register({
    prototype: {
      readyCallback: function() {
        this.innerHTML = section.innerHTML;
      }
    }
  });
}

You would package these files together with this command:

wcpack -o component.html tabs.html

This simply tells wcpack to package the component defined in tabs.html and write the results to component.html. You'd wind up with this output:

<element name="tabs" constructor="TabsHTMLElement">
  <section>I'm tabs!</section>
  <script>
    if (this !== window) {
      var section = this.querySelector('section');
 
      this.register({
        prototype: {
          readyCallback: function() {
            this.innerHTML = section.innerHTML;
          }
        }
      });
    }
  </script> 
</element>

Multiple inputs

Additionally wcpack allows for multiple input files to pack into a single .html file. This is useful when you have a group of components that are related. For example with a tabs component you would likely want to allow for tab elements to be nested. In this case you want to pack these into a single component.

To pack multiple components into one simply path multiple files from the command line:

wcpack -o component.html tab.html tabs.html

or from Node:

var pack = require('wcpack'),
    fs = require('fs');
 
pack('tabs.html', 'tab.html')
  .end(function(output) {
    fs.writeFile('component.html', output, 'utf8', function() {
      // All done!
    });
   });

Or as an array from Node:

pack(['tab.html', 'tabs.html']).end(function(output){ ...

From Node

Everything that can be down from the command line tool can also be done from node. Here's a simple example:

var pack = require('wcpack');
 
pack('./mycomponent.html')
  .indent(2)
  .minify()
  .end(function(output) {
    console.log(output);
   });
