I have a home page with a few inputs and a search button. When the search button (which is a react-router <Link /> component) is clicked, it routes to my /search route. I need access to the search terms that were entered in the previous route to query my database and display the results.
How can I pass the search terms through either the <Link /> component or some other way through the route so that the /search route and component has access to them?
You can pass paramaters to the Link.
<Link to={'/search/foo/bar'}>Search</Link>
Where foo and bar are two parameters to your search view.
In react-router you’ll have :
<Route path="search/:foo/:bar" component={SearchView} />
If you don’t want a query like app.com/search/foo/bar but you want app.com/search?query=foo&filter=bar, I think you can use the property location
this.props.location.query
Which router library are you using?
He uses react router, because the Link component is provided by this router 
Oops, didn’t notice that 
I’ve edited my router to include variables in the path and pass them as a string in the <Link /> components to prop. I can then access those variables in the url via this.props.params.*. This does however seem to affect the paths to local directories (like images in /public) as well as the the href of the <Link />s underlying anchor element. Is this the standard pattern for a search feature?
