How to use the react-tools.React function in react-tools

getComponentByName: function(name) {
    return this.components[name];
  },
  start: function(rootProps, container) {
    var component = this.getComponentByName(rootProps.component),
        content;
    if (!component) {
      return;
    }
    React.renderComponent(component(_.clone(rootProps)), container);
  }
};

// Enable Node.js compatibility
if (typeof module !== 'undefined' && module.exports) {
  var React = require('react-tools').React,
      _ = require('underscore'),
      $ = require('jquery');
  module.exports = Fresh;
}

Fresh.serialize = {
  getPropsFromQueryString: function(queryString) {
    var props = {};
    if (queryString.length) {
      var pairs = queryString.split('&'),
          parts,
          key,
          value;
      for (var i = 0; i < pairs.length; i++) {
        parts = pairs[i].split('=');
        key = parts[0];
