Before submitting a pull request, please make sure the following is done:

Fork the repository and create your branch from master.
Run yarn in the repository root.
If you've fixed a bug or added code that should be tested, add tests!
Ensure the test suite passes (yarn test). Tip: yarn test --watch TestName is helpful in development.
Run yarn test-prod to test in the production environment. It supports the same options as yarn test.
If you need a debugger, run yarn debug-test --watch TestName, open chrome://inspect, and press "Inspect".
Format your code with prettier (yarn prettier).
Make sure your code lints (yarn lint). Tip: yarn linc to only check changed files.
Run the Flow typechecks (yarn flow).

I havent added test as of now, because I dont know how to.
partial hydration throws direct error, its hydration through loadable component using ssr, causes this issue, I made changed to ssr fixtures to show that it works, but cant find a way to modify following to make test suite do the same thing

can anyone help?

it('should be able to use lazy components after hydrating with portal', async () => {
    class Child extends React.Component {
      render() {
        if (!document.getElementById('root')) {
          return null;
        }
        const root = document.getElementById('root');
        return ReactDOM.createPortal('World', root);
      }
    }

    const Lazy = React.lazy(
      () =>
        new Promise(resolve => {
          setTimeout(
            () =>
              resolve({
                default: () => <Child />,
              }),
            1000,
          );
        }),
    );
    class HelloWorld extends React.Component {
      state = {isClient: false};
      componentDidMount() {
        this.setState({
          isClient: true,
        });
      }
      render() {
        return (
          <div id="root">
            Hello{' '}
            {this.state.isClient && (
              <React.Suspense fallback="loading">
                <Lazy />
              </React.Suspense>
            )}
          </div>
        );
      }
    }

    const element = document.createElement('div');
    element.innerHTML = ReactDOMServer.renderToString(<HelloWorld />);
    expect(element.textContent).toBe('Hello ');

    ReactDOM.hydrate(<HelloWorld />, element);
    expect(element.textContent).toBe('Hello loading');

    jest.runAllTimers();
    await Promise.resolve();
    Scheduler.flushAll();
    console.log();
    expect(element.textContent).toBe('Hello world');
  });

more so my issue with creating test is that a document has been declared globaly

cpojer · 2019-04-25T09:44:08Z

Does it make sense to throw when trying to render a portal on the server or should they just be ignored instead?

ljharb · 2019-04-25T15:23:06Z

If they throw, then a component using portal can’t be server rendered - but if they’re ignored, then there’ll be a client-server dom mismatch on initial render. What would be ideal for me is if they’re ignored on the server for rendering, and rendered on the client but ignored for the purposes of the mismatch algorithm, if I’m understanding things correctly.

VariableVasasMT · 2019-04-26T12:28:04Z

@cpojer @ljharb on the fair note, this specific issue is not server related, the hydration occurs on client, I dont think if there would be dom mismatch because of it, or may be I dont understand enough.

ljharb · 2019-04-26T15:39:10Z

My understanding is that hydration is the initial render on the client on top of the initial server render, and effectively that must not produce a dom diff (altho i think there’s some wiggle room in there to account for subtle html differences). Which means, that if something is rendered in hydration, that i suspect it needs to have also been rendered on the server - or, the diffing algorithm needs to special-case allowing it.

VariableVasasMT · 2019-04-29T19:10:23Z

diffing algorithm needs to special-case allowing it.

@ljharb I agree with the latter, but is it worth it considering #13097 is open?
As much I understood, HostPortal is not passed to fibre or render tree

case HostPortal:
          pushHostContainer(
            workInProgress,
            workInProgress.stateNode.containerInfo,
          );
          break;

after this we loose the context of Portal, I think but I am not sure,
it should be handled like

case SuspenseComponent:

which does this

updateDehydratedSuspenseComponent

I am not sure though and I am sorry if this seems naive.

ljharb · 2019-04-29T20:25:52Z

I'm not really sure ¯\_(ツ)_/¯ but presumably the first one to land shouldn't presuppose the existence of the other :-)
