Well, I try to understand legacy code with React routes onboard.

I have an url like

/home/reports/some_report_numbers

when user changes the ulr like that:

/home/reports/some_report_numb

I want to check if "some_report_numb" exists in props, in this.props.location.pathname. If exists - fine, go that way, otherwise go another way.

Maybe it is a wrong approach at all? Well, when the report is shown and user just deletes some letters in url I need to redirect to /home/ page. To do that I need somehow to check if that report with that numbers exists at all.

Maybe it could be done via

<Route name=SomeRouteName path='reports/:reportId' component=HomePage />

According to the documentation of react-router-dom

Link: https://reacttraining.com/react-router/web/example/url-params

match become an object that can be used in your component. Like explain in the documentation, you have access to match object with the following steps:

• 
  Route component as this.props.match
  


• 
  Route render as ( match ) => ()
  


• 
  Route children as ( match ) => ()
  


• 
  withRouter as this.props.match
  


• 
  matchPath as the return value
  

For example, if you have the following route:

<Route path="/reports/:reportId" component=HomePage />

In your component, you can access to this with: this.props.match because it's an object and inside it, you will have what you want.

After that, you could check what params you have in your URL.

Now, if you want to redirect the user, you can use <Redirect to='/your/path' />
