Also, it's important to note that SPAs using router packages like react-router or vue-router must take some extra steps to handle things like changing meta tags when navigating between router views. This is typically handled using a Node.js package like vue-meta or react-meta-tags.
What is router-view? Here’s how linking to different “pages” in a single page app works in five steps in React:
When a user visits a React website, a GET request for the .indextml file is sent to the server.
The server then sends the indextml page to the client, which contains the scripts that start React and React Router.
The web application is then loaded on the client side.
If the user clicks a link to a new page example, a request tunisia mobile database for the new URL is sent to the server.
React Router intercepts the request before it reaches the server and handles the changes to the page itself. This is achieved by locally updating the rendered React components and changing the URL client-side.
In other words, when a user or bot follows a link to a URL on a React website, they are not served multiple static HTML files. Instead, the React components hosted in the root .indextml file like the header, footer, and body content are simply being reorganized to display different content. That's why they are called single-page applications!
Potential SEO issues: Therefore, be sure to use a package like React Helmet to ensure that users are provided with unique metadata for each page or "view" when browsing your SPA. Otherwise, search engines may crawl the same metadata for every page, or worse, none at all!
In the big picture, how does all this affect SEO? Next, we need to understand how Google handles JavaScript.
