Package Exports

mutate-dom

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (mutate-dom) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

<div class="user">
  <div class="name">John</div>
  <div class="ava-container">

  </div>
</div>

The code that mutates the HTML.

var mu = require('mutate-dom');

function toJQuery(fn) {
  return function(selector) {
    var $el = $(selector);
    return fn($el);
  };
}

mu.addClass = function(newClass) {
  return toJQuery(function($el) {
    $el.addClass(newClass);
  });
};

mu.src = function(src) {
  return toJQuery(function($el) {
    $el.attr('src', src);
  });
};

mu({
  '.user': {
    '.name': 'Bill',
    '.ava-container': [{
        'img': mu.src('http://api.randomuser.me/portraits/thumb/men/59.jpg')
      },
      mu.addClass('awesome-ava-container')
    ]
  }
});
