So far, our Q&A app only contains a single page and the time has come to add more pages to the app. React Router is a great library that helps us manage navigating between different pages, so we are going to bring it into our project in this chapter.

In this chapter, we will declaratively define the routes that are available in our app and handle pages that aren't found. We'll implement a page that displays the details of a question, along with its answers, where we will learn how to implement route parameters. We'll begin by implementing the question search feature, where we will learn how to handle query parameters. We will also start to implement the page for asking a question and optimize this so that its JavaScript is loaded on demand rather than when the app loads.

We'll cover the following topics in this chapter:

• Installing React Router with types
• Declaring routes
• Handling routes not found
• Implementing links
• Using route parameters
• Using query parameters
• Lazy loading routes
