![]() ![]() So in our app, we can expect that Home should be rendered only when the user navigates to / and that About should only be displayed if the user goes to the /about directory. Rename and archive the Remix repo from 'remix' to 'remix-archive'. This routing can either be a client-side (in our case) or server-side rendering. It is a third party library that allows us to seamlessly perform routing in React app. ![]() It also has the longest history on the web with issues, PRs, and back links over the last 7 years. In React, we use React router to keep track of the current URL and renders different views as it changes. The exact prop essentially tells React Router to render the Route's component if the pathname matches the URL exactly. Merge Remix into the React Router repository because React Router is the primary dependency of everything were doing. To do so, we need to use the exact prop in our Route component. Namely, you need to be comfortable with two of React Routers most foundational components Route. However, in order to help us better answer those questions, there are some topics we need to cover first. Let’s now work on correcting this problem. A solid understanding of how, when, and why to create nested routes is foundational to any developer using React Router. What is React Router First created in 2014, React Router is a declarative, component based, client and server-side routing library for React. Consequently, About was not rendered to the DOM. So on /about, now that Home was rendered (the first Route component that matched the URL), Switch halted the URL matching process. Recall that Switch only renders the first Route component that matches the URL. Since this condition was true, Home was rendered. So when we navigated to /about, React Router first performed a check of whether the URL contained the /.Line 3: We told React Router to render About if the URL contains a /about.Line 2: We told React Router to render Home if the URL contains a /.It will only render the first Route component that matches the current URL. ![]() The Switch componentĪccording to React Router’s documentation, the Switch component essentially stops the whole process of going through all of the route paths as soon as it matches the URL. To rectify this issue, we need to use the Switch component. So in a nutshell, by default, React Router will render all of the components that are subroutes of each other. Additionally, since the path contained the about keyword, then the About component is being rendered as well. Since this condition is true, Home is being displayed again. Now according to line 6, if we go to the /about page, React Router first checks if the route contains a /.According to line 5, we told React to render the Home component if it encounters a slash ( / ) in the path prop of any child Route component.So in this piece of code, it essentially goes through all of these Route components. (Line: 37) Expose our 'logout' method by registering the 'value' attribute of 'AuthContext.Provider'.Īdd the 'Logout' button as a menu item in the 'Layout' component.The reason is that Router just checks the route paths without being too specific.Then empty the 'user' state variable and then navigate to 'login' page. Then remove the user profile information from the browser's local storage. (Line: 28-33) Invoking the 'Logout' API call.Src/components/shared/AuthContext.js: import axios from "axios" ![]()
