Property ‘$router’ does not exist on type ‘createcomponentpublicinstance

The error message “Property ‘$router’ does not exist on type ‘createcomponentpublicinstance'” occurs when you try to access the ‘$router’ property on an object of type ‘createcomponentpublicinstance’ but this property does not exist on that type.

This error commonly occurs in Vue.js applications when you are trying to access the router instance within a component, but forgot to import or inject it properly.

To resolve this error, you need to ensure that the ‘$router’ property is available in the current context. Here are a few possible solutions:

  1. If you are using the Vue Router, make sure you have properly installed and configured it in your project. You can install it using the following command in your terminal:

    npm install vue-router

    Then, you need to import and use it in your main Vue instance as follows:

    import Vue from 'vue'
    import VueRouter from 'vue-router'
    
    Vue.use(VueRouter)
    
    // Create your routes and router instance
    const routes = [
      // define your routes here
    ]
    
    const router = new VueRouter({
      routes
    })
    
    new Vue({
      router, // make the router instance available in your app
      // ...
    }).$mount('#app')

    With this setup, the ‘$router’ property should be available in your components.

  2. If you are using a Vuex store, make sure you have correctly defined and injected the ‘$router’ property in your store. Here is a basic example of how you can achieve this:

    // main.js
    import Vue from 'vue'
    import Vuex from 'vuex'
    import router from './router' // assuming you have a router file
    
    Vue.use(Vuex)
    
    const store = new Vuex.Store({
      state: {
        // your state properties
      },
      mutations: {
        // your mutations
      },
      actions: {
        // your actions
      },
      getters: {
        // your getters
      },
      plugins: [
        // define a plugin to inject the router instance in your store
        store => {
          store.$router = router
        }
      ]
    })
    
    // ...
    
    // Component.vue
    export default {
      // ...
      created() {
        // Now you can access the router instance using this.$router in your component
        console.log(this.$router)
      },
      // ...
    }

    By injecting the router instance in your store, you can access it in your components through ‘$router’ property.

  3. If you are not using Vue Router or Vuex, double-check your component’s code to ensure you are correctly importing and using the necessary dependencies related to routing. Make sure you have imported the necessary modules and libraries, and you are using them according to their documentation.

Remember to adapt these solutions based on your specific use case and project structure. By properly configuring and injecting the router instance, you should be able to resolve the error message “Property ‘$router’ does not exist on type ‘createcomponentpublicinstance'” in your Vue.js application.
