Liquor

Liquor is a templating engine for node. It's very lightweight. It's essentially embedded javascript with some shorthand significant whitespace notation available. This is to discourage use of raw code and make templates look nicer.

Usage

Backticks are used for evaluation, while #{} is used for interpolation.

?:data
  <table>
    <tr>
      @:col
        <td>#{this}</td>
    </tr>
    @:data
      <tr>
        <td>#{this.color}</td>
        <td>#{this.animal}</td>
      </tr>
  </table>

!:data
  <div>
    ?:error
      <p>Sorry, there was a problem: #{error}.</p>
      <p>Please, try again!</p>
    !:error
      <p>Sorry, no error message.</p>
  </div>

Is essentially shorthand for:

`if (typeof data !== 'undefined' && data) {`
  <table>
    <tr>
      `each(col, function() {`
        <td>#{this}</td>
      `})`
    </tr>
    `each(data, function() {`
      <tr>
        <td>#{this.color}</td>
        <td>#{this.animal}</td>
      </tr>
    `})`
  </table>
`} else {`
  <div>
    `if (typeof error !== 'undefined' && error) {`
      <p>Sorry, there was a problem: #{error}.</p>
      <p>Please, try again!</p>
    `} else {`
      <p>Sorry, no error message.</p>
    `}`
  </div>
`}`

`/* liquor also exposes an "each" helper function */`
`/* it is the same one used internally for @ statements */`
`if (messages)
  each(messages, function(message, key) {`
    <p>#{key}: #{message.content}</p>
  `})`

If you're worried about the notorious "undefined" problem with variables expressed in raw evaluation of JS, you can access them as properties on a variable called $, which exists within the context of a template, and holds all of the locals and helpers:

e.g.

`if ($.messages) {` <p>#{JSON.stringify(messages)}</p> `}`
