How to use react-meta-tags - 4 common examples

// console.log(_route.component);
  // console.log(_route.component.loadData);

  if (_route.loadData) {
    context = await _route.loadData({ store, match: _match })
    // console.log(context);
  }

  await _route.component.preload()

  // await Loadable.preloadAll();

  // 获取路由dom
  const _Router = router.dom
  const metaTagsInstance = MetaTagsServer()

  let _mainContent = (
    
      
        
          <_Router />
        
      
    
  )

  // html
  let html = ReactDOMServer.renderToString(_mainContent)

  // 获取页面的meta，嵌套到模版中
  let meta = metaTagsInstance.renderToString()

const Page: any = router.dom;
    
    let _p = await route.body.preload();

    if (_p.default.loadDataOnServer) {

      params.redirect = redirect;
    }

    // console.log(_p);
    // context={params.context}
    
    let metaTagsInstance = MetaTagsServer();    

    // html
    params.html = ReactDOMServer.renderToString(
