vue.js - vuejs typescript property router does not exist

Question

I try to access router in my typescript class component:

import {Vue} from 'vue-property-decorator'
import Component from 'nuxt-class-component'
import {Getter, Action} from 'vuex-class'

@Component
export default class Login extends Vue {
    @Action login

    username = ''
    password = ''

    async submit () {
        await this.login({username: this.username, password: this.password})
        this.$router.push('/results')
    }
}

Unfortunately, I get:

error TS2339: Property '$router' does not exist on type 'Login'.

Answer 1

Shim the vue file and include $router:

Make a typings file called vue-shim.d.ts

Adjust your shim like this:

import VueRouter, { Route } from 'vue-router'

declare module 'vue/types/vue' {
  interface Vue {
    $router: VueRouter
  }
}

now Vue (in your case -- this) will have a property of $router and typescript won't complain.
