ReactRouterv4 and componentDidMount?

Question

React

The crux of the matter is what.
There is a regular route:

<Route exact path='main/:iduser' component={UserOffice} />

There is a normal link: in the component in the componentDidMount () method, for example, a fetch occurs in the database. the bottom line is that the UserOffice component is mounted only once, and then only the props change if we change only the params in the url . What is the way out to pull a new user along a new param?
<Link to='main/123' />

Answer 1

componentDidUpdate(prevProps) {
  if (this.props.match.params.iduser !== prevProps.match.params.iduser) {
    this.fetchUserData();
  }
}
