Freshly installed, when i tryed to run hello world program, this error hapened: Uncaught ReferenceError: ReactDOM is not defined

This is my react:

  render: function() {
    return (
      <p>
        Hello, <input type="text" placeholder="Your name here" />!
        It is {this.props.date.toTimeString()}
      </p>
    );
  }
});

setInterval(function() {
  ReactDOM.render(
    <HelloWorld date={new Date()} />,
    document.getElementById('example')
  );
}, 500);

O_o Why arent't the newest version of React on master ?

It's actually already on master: https://github.com/reactjs/react-rails/blob/master/lib/assets/javascripts/react_ujs.js.erb#L57

The change from a single JS package to many modules has complicated the process for building React.js into the gem code, see full discussion here: #365

I'm on the road this week so I haven't had a chance to find a new way yet!

[rmosolgo]

Please try gem version 1.4.0 which includes React 0.14 and open an issue if you have any trouble!

Have the same error on fresh install. react-rails (1.10.0)
Could please anyone help?

thanks for fast reply! so I can not use react_component view helper?

[IvRRimum]

You can. Go trough the answers on the stackoverflow question i posted. Loads of discussion and solutions there.

[kukula]

I've checked answers, but I'm not calling ReactDOM.render, I'm using react_component view helper in my view. Question is not about React itself, question about this gem.

@kukula Then you are asking at the wrong issue i guess. In this issue we discuss the problem with ReactDOM.render. Wish the best of luck to you!

[kukula]

thank you, I'll create a new issue than.
