React EVA是一个让开发同学能够在React技术体系下，利用EVA JS的游戏研发能力，开发动画、游戏类场景的框架。它可以让开发同学用熟悉的JSX和Hooks语法编写动画、游戏场景的代码。

import createRenderer from './renderer'; // const containers = new Map<FiberRoot, any>();

function getPublicRootInstance(container) {
  var containerFiber = container.current;

  if (!containerFiber.child) {
    return null;
  }

  return containerFiber.child.stateNode;
}

var _createRenderer = createRenderer(),
    createInstance = _createRenderer.createInstance,
    reconciler = _createRenderer.reconciler; // export {createInstance, reconciler};


var Reconciler = {
  render: function render(element, container, props) {
    // Create a root Container if it doesnt exist
    if (!container._rootContainer) {
      container._rootContainer = reconciler.createContainer(container, false);
      createInstance(props);
    }

    return reconciler.updateContainer(element, container._rootContainer, null); // return getPublicRootInstance(container);
  },
  unmountComponentAtNode: function unmountComponentAtNode(container) {
    reconciler.updateContainer(null, container._rootContainer, null, function () {//noop
    });
  }
};
export default Reconciler;
