According to the accepted answer to this question, React Router 4 doesn't match query parameters anymore. If I go from a URL matched by one of my <Route>s to the same URL with a different query string, the content doesn't seem to change. I believe this is because navigating between URLs that match the same <Route> doesn't change the content, but please correct me if I'm wrong. Given this, how do I use React Router for a set of URL's that need to differ only by query parameter?
For example, many search engines and other sites that use search bars, including the site I am working on, use a query parameter, commonly q or query. The user may search for one thing, then decide that is not what he/she wants and search for another thing. The user may type in the second URL or search with the search bar again. There isn't really a place for the search term in the URL path, so it kind of needs to go in the query string. How do we handle this situation?
Is there a way, with React Router, to link to a URL that only differs in the query string and change the content, without refreshing the entire page? Preferably, this wouldn't require any external library besides React and React Router.
Try the render function prop instead of component prop of Route. Something like this:
<Route render={props => {
// look for some param in the query string...
const useComponentA = queryStringContains('A');
if(useComponentA) {
return <ComponentA {...props}/>;
} else {
return <ComponentB {...props}/>;
}
}}/>
