jarg

JavaScript template engine powered by arrays, inspired by Clojure.

Target languages

HTML

Using

const html = require('jarg').html 

const template =
  ['tagName', { optionalObjectWithAttributes },
    anotherTagsOrJustText]

html(template) // => HTML string

Examples

['div', { class: 'messages' },
  ['p', 'Some message'],
  ['p', 'Other message'],
  'Just text']

will rendered into

<div class="messages">
  <p>Some message</p>
  <p>Other message</p>
  Just text
</div>

With jarg.html conditional rendering becomes a trivial thing:

const greetingComponent = name =>
  ['div',
    'Hello ', name || 'stranger', '!']

html(greetingComponent('jarg')) // => <div>Hello jarg!</div>

And you can use some components inside others, by dividing your application into many independent parts:

const todos = ['Program something', 'Eat', 'Kill spiders']

const todoList = todos =>
  ['ul',
    ...todos.map(todo => ['li', todo])]

const todoApp =
  ['div',
    ['h3', 'TODO'],
    todoList(todos),
    ['form', { action: 'someUrl' },
      ['label', 'What needs to be done?'],
      ['input'],
      ['button', 'Add']]]

html(todoApp)

Comments and restrictions

Each template should have only one root tag.
