Deep cloning of react components

cloneComponent.js

var _ = require('lodash');

function isComponent(obj) {
  //ghetto check because JS
  return (obj && obj.setState)
}

function deepCloneComponent(tpl) {
  if (!tpl) return;
  if (_.isArray(tpl)) {
    return _.map(tpl, function(component) {
      return deepCloneComponent(component);
    })
  }
  if (!isComponent(tpl)) return _.clone(tpl)
  var new_props = _.clone(tpl.props);
  if (new_props) new_props.children = deepCloneComponent(new_props.children);
  return tpl.constructor.ConvenienceConstructor(new_props);
}

There is now _.cloneDeep https://lodash.com/docs/4.17.4#cloneDeep
