Installing

$ npm install --save-dev hmrc/component-library-template

Developing Locally

To see your changes to hmrc-component-library-template locally you'll need to link the package with npm:

$ git clone https://github.com/hmrc/component-library-template
$ cd /path/to/component-library-template
$ npm link
$ cd /path/to/assets-frontend
$ rm -rf node_modules/hmrc-component-library-template
$ npm link hmrc-component-library-template

Manually update

Then every time you make an update to the template, just re-link and start the build again:

# Inside assets-frontend
$ npm link hmrc-component-library-template

Update with a watch

Inside of assets-frontend there is a task to add a watch using nodemon. This will npm link hmrc-component-library-template and build the Component Library. You need to pass in the location of the folder where your local checkout of the hmrc-component-library-template can be found, relative to the assets-frontend's package.json

$ npm run comp-lib:watch -- -w ./path/to/hmrc/component-library-template

e.g:

$ npm run comp-lib:watch -- -w ./../component-library-template

Adding Custom Comment Tags

If you wish to pass custom data from your .sass comments to the component-library-template you can do so by adding a custom tag. To add a custom tag add the tag name to the custom array in your kss config.json

e.g.

  // config.json
  "custom": [
    "Example"
  ]
  
  // stylesheet.scss
  /*
  Component title
  
  Example: some data
  
  Styleguide: Component
  */
  
  // index.html
  {{example}}

Adding Custom Handlebars Block Helpers

Block helpers make it possible to define custom functionality that is applied to what you wrap them with.

e.g.

// helpers/customHelperFile.js
Handlebars.registerHelper('bold', function(options) {
  return new Handlebars.SafeString(
      '<div class="mybold">'
      + options.fn(this)
      + '</div>');
});

// index.html
{{#bold}}
  Some content that will be bold.
{{/bold}}

You can add custom helpers by adding a file to the helpers directory. Read the handlebars documentation or follow an example found within this folder. Theses helpers are available to use in your templates.
