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.
