[Solved but worth investigating] Cannot start app after updating to lastest expo client app


#1

Last night I got prompted and updated my expo app to the latest one. After that, my app can’t even start. It will freeze forever in the loading screen, with “downloading javascript bundle” at the bottom, after js bundle already built. After driving my mac fans like crazy for some time, it will show an “Out of memory” error.

I have tried updating xde, expo sdk to 20.0.0, but none of these works. However, I can successfully open a brand new expo init project.

My App.js

export default class App extends Component {
  constructor() {
    super();
    this.state = {
      assetsAreLoaded: false
    };
  }
  componentWillMount() {
    console.log('componentWillMount');
    this.setState({ assetsAreLoaded: true });
  }
  componentDidMount() {
    console.log('componentDidMount');
  }
  render() {
    if (!this.state.assetsAreLoaded) {
      return <AppLoading />;
    }
    return (
      <Provider store={store}>
        <AppNavigator />
      </Provider>
    )
  }
}

It will not even log anything. Only “componentWillMount” is logged after showing the “Out of memory” error.
This is not my original structure. But after restructuring and removing a lot of things, it still has the same bug.

My app is going to launch and after this update i can’t even start up my app. It is really frustrating. Does anyone has the same problem?

UPDATE

It seems to be some problems when loading assets in my app. It will successfully run if I change <AppNavigator /> to <View />.

UPDATE: Solved

I have a console.log(this); in my componentWillMount, which only logs the state, navigation, props, etc before the update. But it somehow maybe logging almost the whole project now and so it never finishes and got out of memory. It is not a common case but it is caused by maybe the changes for the “faster loading” in v20.0.0. So I think the expo team should be aware of this and maybe have some fixes or caveat doc.
