I have a react app with multiple routes. On one of my routes I only want to render a certain component if the user navigated from a specific route. How do I check the previous path used to get to the current route? Thanks

I'm building up a website using ReactJS, REdux,React-Router.I want to access the data upon a different Route i.e for search functionality but I'm unable to do so. I'm only able to access data upon same page.
My App Component
Home Component
I'm dispatching the Action from SearchComponent to store.
I want to access data on /Search Route but unable to do so.
You should point to the component in route element.
Add the component attribute to the route element, pointing towards the component that it should use when hitting the search route.
Remember to import the component first.
What I want is to prevent some routes from being triggered manually via the browser URL. So, is there any way to tell if the route to be applied has been triggered manually(typing in the browser URL location) or through React router (<Link> or useHistory().push)?
When a user manually browses the entire app is remounted, when react router is used the route is "fake" and only what is new is mounted. You could set window.location to state in a component above your routing logic that is set on mount. This would stay the same when react router does the routing, but change when manually routing since the app would remount. You could examine this route for sub-paths to see if the user manually browsed.
I would suggest using protected routes instead. You could "enable" the routes when the conditions you need in your app are met.
I'm trying to redirect non-matching urls to a specific route using React-Router. For example, if user navigates to https://www.mysite/com/no-match and I don't have a corresponding route set up, it should push them to https://www.mysite/com/home.
I'm sure there's a way to do this but can't find it in docs.
For any AngularJS folks, this would be equivalent to $urlRouterProvider.otherwise('/home')
Any advice is appreciated!
There is a subcomponent of React Router that is perfect for this. You're looking for the Redirect component: Redirect Docs.
You can place this as a child to the route that you want to redirect and it should take care of this functionality for you.
In the React-Router documentation I have seen that It has import both Route and Router modules from react-router-dom. I would like to know what is the different between those two modules?
Router
Router component is what makes the connection between browser location and the react application. It doesn't render anything visible on your page. It just exposes API to interact with location changes of the browser via React context. So any component down the tree can use this API to change their behavior based on location changes in the browser or change the browser location into what they want.
Router is the abstract for all other specific router components. Practically, we use a specific implementation of it like BrowserRouter, MemoryRouter, and HashRouter which use different methods to manage browser history. Also, Router is usually a top-level component in the component tree and use only one time in the entire application. All other react-router components should be descendants of Router as they can't function without the API which Router provides.
Route
Route is much simple to explain. It just renders some UI when a location matches the route’s path. So an application can have many Routes based on its layout complexity in different levels of the component tree. Also, Route has some additional props to configure how the match should happen. Route internally use API provided by Router to access the location and decide whether to render the given component or not.
I don't get the docs from React Router below:
But now Home can't participate in routing, like the onEnter hooks,
etc. You render in the same position as Accounts and Statements, so
the router allows you to have Home be a first class route component
with IndexRoute.
What does he mean by routing here? What is onEnter hooks?
Since App is wrapping other routes, the route that matches the given url is passed to App to be rendered via this.props.children. Because of this, you don't get access to react-router's hooks for Home if you do render Home via a statement such as {this.props.children || <Home/>}. One such hook isonEnter, which fires off a callback whenever a route is entered.
When you define Home as an IndexRoute, it is a distinct route that will match whatever route App matches. This way, we don't need the or clause in App, we can just render the child route via {this.props.children}
The docs here are a little more straightforward:
Imagine we'd like to render another component inside of App when the
URL is /. Currently, this.props.children inside of App's render method
is undefined in this case. We can use an <IndexRoute> to specify a
"default" page.
As far as onEnter the docs here are better:
Routes may also define onEnter and onLeave hooks that are invoked once
a transition has been confirmed. These hooks are useful for various
things like requiring auth when a route is entered and saving stuff to
persistent storage before a route unmounts.
