Transcript

- Now that we have the navigation links in the app, we want the views to actually change when we click on them. But that's the job with the route component. The route component is from the react query to DM library. It's used to define which component tree should be rendered when a particular location matches the route path. This component is one of the most important to understand, if you want to add route into your app. It can receive some props when it's used. These are paths, a render method, and some other options. The path isn't anything more than the part of the URL we want this route to work with. Usually, you'll define a route component for every two attribute you're using your application. The path is defined as a string or an array of strings. The easiest and recommended way to render from a route is to our child components to it. However, there are three other ways to render from a root. These are considered legacy, as they were the way to render on routes before Hawks were introduced. You can supply a component's tribute with the name of the component to rendering curly braces. You can use the render attribute. This requires a call back the return to component, or you can use the children attribute, which is useful in animations. As you can render on this route, whether the path matches the location or not. The options that can be supplied, make the route more specific. Using exact means that the root will only match, if the path supplied matches location, pathname exactly. Adding strict means that paths where the trends slash included will only match a location's pathname that has a trailing slash. Strict has no effect, if there are additional URL segments in the location's pathname. Supplying a location prop needs it's value to be an object. When matching a root, it uses the current history location and the paths supplied. The location prop allows for a location with a different pathname to be matched. As with the children render method, this is useful in animations. The final option in the API for route is sensitive. When used, it defines that the path and the location pathname must be a case match as well.
