[Solved]-React Router not updating content on url change-Reactjs

componentDidUpdate() can be leveraged to compare current and previous query strings in order to detect changes in location for instances where components are not dismounted.

// Did Update.
componentDidUpdate(previousProps) {
  const currentSearch = this.props.location.search
  const previousSearch = previousProps.location.search
  if (currentSearch !== previousSearch) updateDesigner()
}
