React not rendering view when Link tag used inside redux

[themirror178]

After doing some researching, I found a similar issue regarding Redux's connect and {pure: false} workaround was fixed in react-router 3.0. I'm running react-router 4.0 (as part of react-router-dom) and still find this issue. reduxjs/react-redux#388

//bootstrap

ReactDOM.render(
    <Provider store={myStore}>
        <Router>
            <ConnectedMain />
        </Router>
    </Provider>, root_elem);

var ConnectedAdminMain = connect( mapStateToProps, null, null)(Main);

// Main

<div className="col-lg-12">
   <Route exact path="/" component={TestOne} />
      <Route path="/:id" component={ TestOneDetails} />
   </div>

// TestOne
Has <Link to="/foo">bar</Link>

Version

4.0.0
"react-redux": "^5.0.2",
"react-router-dom": "^4.0.0",

Test Case

Steps to reproduce

Expected Behavior

1. Link changes in URL
2. View re-renders

Actual Behavior

1. Link changes in URL
2. View does not re-render
3. Refreshing the browser renders the correct view.

{ pure: false } would fix your issue. Otherwise, please see https://github.com/ReactTraining/react-router/blob/master/packages/react-router/docs/guides/blocked-updates.md (or if you want a longer read, you can check out this article I wrote that goes into some more detail about the problem).

Is { pure: false } the solution, or the workaround? Apart from using HOCs or pathless routes, from your post.

Anything that allows for your connected component to update when the location changes would work. Passing a location prop means that sCU can still block updates when the location has not changed. Whether this is important will vary from project to project, but I would say don't feel obligated to turn off all update blocking just for React Router's sake.

What about the nested <Route> components? Are they prone to the same issue?

React.render(
  <Router>
      <Route path="/", render={({ match }) => <App matchUrl={match.url}>} />
  </Router>
)

class App extends PureComponent  {
  render() {
    const { matchUrl } = this.props;
    return (
       <div>
           <Link to={matchUrl} >Home</Link>
           <Link to={`${matchUrl}about`} >Home</Link>
           <Route exact path={matchUrl} render={() => <h1>Home Component</h1>} />
           <Route path={`${matchUrl}about`} render={({ location }) => <h1>About {location.url}</h1>} />
       </div>
    )
  }
}  

In other words, does it mean I always have to pierce all the shouldComponentUpdates between Routes as well?

import { withRouter } from 'react-router-dom'
export default withRouter(connect(mapStateToProps)(Something))

this does the trick. https://reacttraining.com/react-router/web/guides/redux-integration

withRouter() works, but you have to put it on the right component. For me that was the child of the <Router> component.
Too bad none of the solutions mentioned on which component you had to put the "withRouter()" nonsense
