useRouter	The useRouter composable returns the router instance.

useRouter

The useRouter composable returns the router instance and must be called in a setup function, plugin, or route middleware.

Within the template of a Vue component, you can access the router using $router instead.

If you have a pages/ folder, useRouter is identical in behavior to the one provided by vue-router. Feel free to read the router documentation for more information on what each method does.

Basic Manipulation

• addRoute: Add a new route to the router instance. parentName can be provided to add new route as the child of an existing route.
• removeRoute: Remove an existing route by its name.
• getRoutes: Get a full list of all the route records.
• hasRoute: Checks if a route with a given name exists.

Based on History API

• back: Go back in history if possible, same as router.go(-1).
• forward: Go forward in history if possible, same as router.go(1).
• go: Move forward or backward through the history without the hierarchical restrictions enforced in router.back() and router.forward().
• push: Programmatically navigate to a new URL by pushing an entry in the history stack. It is recommended to use navigateTo instead.
• replace: Programmatically navigate to a new URL by replacing the current entry in the routes history stack. It is recommended to use navigateTo instead.

TIP: router.addRoute() adds route details into an array of routes and it is useful while building Nuxt plugins while router.push() on the other hand, triggers a new navigation immediately and it is useful in Nuxt Page components, Vue components and composable.

const router = useRouter();
router.back();
router.forward();
router.go();
router.push({ path: "/home" });
router.replace({ hash: "#bio" });

Navigation Guards

useRouter composable provides afterEach, beforeEach and beforeResolve helper methods that acts as navigation guards.

However, Nuxt has a concept of route middleware that simplifies the implementation of navigation guards and provides a better developer experience.

Promise and Error Handling

• isReady: Returns a Promise that resolves when the router has completed the initial navigation.
• onError: Adds an error handler that is called every time a non caught error happens during navigation.
• resolve: Returns the normalized version of a route location. Also includes an href property that includes any existing base.

Universal Router Instance

If you do not have a pages/ folder, then useRouter will return a universal router instance with similar helper methods, but be aware that not all features may be supported or behave in exactly the same way as with vue-router.
