Protected routes and authentication with React Router v4

Protected routes and authentication with React Router v4  #ReactJS

  • In this post we’ll break down the “Redirects (Auth)” example on the React Router documentation to learn how to create authenticated routes (routes that only certain users can access based on their authentication status) using React Router.
  • It would be nice if, just like React Router gives us a component, they also gave us a component which would render the only if the user was authenticated.
  • So now what we’re doing is when the user authenticates, we change to true which causes a re-render and then renders the component taking the user to the route.
  • First, inside of our component when we redirect the user for not being authenticated, we’ll need to pass along the current route they’re trying to visit so we can come back to it after they authenticate.
  • Now we need to modify our component so that if the user was redirected there from a previous route, once they authenticate, they’re taken back to that original route.

Often times when building a web app you’ll need to protect certain routes in your application from users who don’t have the proper authorization. Though React Router doesn’t provide any functionality for this out of the box, it was built with composability in mind which means adding it is fairly straight forward.

Before we even go about creating our protected routes, we’ll need a way to figure out if the user is authenticated. Because this is a tutorial about React Router protected routes and not about authentication, we’ll use a dummy object to mock our auth service.

Now that that’s out of the way, let’s build out the components that’ll be rendered by React Router when certain paths match. There are going to be three: a component, a component, and a component. and will be simple. will be a little more complex so we’ll just build out the skeleton of it for now and finish the rest later.

Now that we have some components, the next step is to start rendering some s. Before we start worrying about creating any protected routes, let’s…
