a declarative and universal way to specify window.location in a single-page React apps

React Redirect Side Effect

Fork of react-redirect working with last React version (>=15.4.0).

Provides a declarative way to specify window.location in a single-page app. This component can be used on server side as well.

Built with React Side Effect.

====================

Installation

npm install --save react-redirect

Dependencies: React >= 15.5.0

Features

• Like a normal React compoment, can use its parent's props and state;
• Can be defined in many places throughout the application;
• Supports arbitrary levels of nesting, so you can define app-wide and page-specific titles;
• Works just as well with isomorphic apps.

Example

Assuming you use something like react-router:

var App = React.createClass({
  render: function () {
    // Redirect to "www.driftt.com" if no child overrides this
    return (
      <ReactRedirect location='www.driftt.com'>
        <this.props.activeRouteHandler />
      </ReactRedirect>
    );
  }
});

var HomePageRedirect = React.createClass({
  render: function () {
    // redirect to "www.driftt.com" while this component is mounted
    return (
      <ReactRedirect location='www.driftt.com'>
      </ReactRedirect>
    );
  }
});

var NewArticlePage = React.createClass({
  mixins: [LinkStateMixin],

  render: function () {
    // Redirect using value from state when this component is mounted
    return (
      <ReactRedirect location={this.state.redirect || ''}>
        <div>
          Redirecting...
        </div>
      </ReactRedirect>
    );
  }
});

Server Usage

If you use it on server, call ReactRedirect.rewind() after rendering components to string to retrieve the redirect location given to the innermost ReactRedirect. You can then embed this title into HTML page template.

Because this component keeps track of mounted instances, you have to make sure to call rewind on server, or you'll get a memory leak.

Example assuming you use express for your server

var middleWare = function(req, res) {
  var html = React.renderToString(React.createElement(component));
  var redirect = ReactRedirect.rewind();
  if (redirect) {
    res.redirect(302, redirect);
  } else {
    res.end(html);
  }
}
