The vue-router error "NavigationDuplicated: Avoided redundant navigation to current location" is encountered in the Vue application - how to solve it?

Vue.js is becoming more and more popular in front-end application development as a fast and flexible JavaScript framework. Vue Router is a code library of Vue.js used for routing management. However, sometimes encountering "NavigationDuplicated" errors in Vue applications can cause difficulties in using Vue Router. This article explains how to resolve this error.

In Vue Router, when we switch between the same routing path multiple times, we will encounter the "NavigationDuplicated" error. For example, if a user clicks the same navigation link multiple times, they will see this error on the console.

The error message generally looks like the following:

"NavigationDuplicated: Avoided redundant navigation to current location: "/your-route-path"

This error message tells us that in Multiple page routing jumps on the same URL address are not allowed. The root cause of this problem is that Vue Router uses the URL path to ensure the correct navigation of the route. If the routing path is the same and the parameters are the same, the route will be Treated as the same route.

Next, we will introduce several methods that can solve the "NavigationDuplicated" error.

Method 1: Use the catch function

We can use The try-catch statement wraps a route navigation, ensuring that we can use the catch function to catch this error and handle it appropriately.

try {
   await this.$router.push(myRoute)
} catch (err) {
   if(err.name !== 'NavigationDuplicated') {
      throw err
   }
}

In this code snippet, we use a try-catch statement to wrap the navigation to the route code. In the try code block, we will navigate to the specified route through $router.push(), which will cause a "NavigationDuplicated" error. In the catch code block, if the error is not "NavigationDuplicated", we will re-throw this error out. If it is a "NavigationDuplicated" error, no other operations are performed.

Of course, this is just one way to solve the problem, and the appropriate call needs to be made in the right place.

Method Two: Ignore duplicate routes

There is a property in Vue Router called "ignoreDuplicates". If it is set to true, you can ignore duplicate routes. This property can be set in the global configuration of Vue Router.

export default new Router({
   mode: 'history',
   base: process.env.BASE_URL,
   routes,
   ignoreDuplicates: true,
})

In this code snippet, we set the ignoreDuplicates property to true, which means if the same route is navigated repeatedly, Vue Router will ignore it.

This is a simple solution , can save the amount of code, but this method may cause the loss of routing or other problems, and needs to be used with caution.

Method 3: Use Vue Router hooks

Vue Router has some life cycle hooks Functions that can execute custom methods when route navigation changes. We can use these hook functions to solve the "NavigationDuplicated" error.

const router = new VueRouter({
      routes: [],
});

router.beforeEach((to, from, next) => {
   if(to.path === from.path) {
      return false;
   }
   next();
});

In this example, we use the beforeEach hook function when the route changes. . If the URL of the next route we want to jump to is the same as the URL of the current route, we will prevent Vue Router from navigating to the new route. This way you can avoid NavigationDuplicated errors.

This is a simple and elegant solution that can effectively solve the "NavigationDuplicated" error that occurs when routing.

It can be seen that the "NavigationDuplicated" error of Vue Router may be one of the common errors encountered in Vue.js application development. Fortunately, we can solve this problem in several simple yet effective ways to provide a better experience for users of Vue.js applications.
