Navigating within components using code is an essential skill when working with Vue Router

I am currently developing a Quasar application powered by Vue 3 with vue-router version 4

All my routes are properly configured and function well when navigating from a component template using

<router-link to="/route">Go to route</router-link>

However, I am struggling to access the router and route objects within my methods. As per the documentation, I should be able to retrieve the router object using this.$router or router, but I am unable to do so.

The structure of my single file component is similar to the following:

  <template>
    <q-page>
      <q-card>
        <q-form @submit="handleSubmit()" > ;
          <q-input v-model="param" />
          <q-btn label="submit" type="submit" />
        </q-form>
        <router-link to="/">Go to Foo</router-link> <!-- This works perfectly -->
      </q-card>
    </q-page>
  </template>

  <script lang="ts">
  import { ref } from 'vue'

  export default {
    setup () {
      const param = ref(null);
      return { param }
    },
    methods: {
      async handleSubmit () {
         // Perform actions
         // Navigate to another route
      }
    }
  }
  </script>

Is there a way for me to access the vue router from the handleSubmit method?

this.$route and this.$router are returning as undefined. It seems that with Vue 3 and Single File Components, this approach does not work. For instance, with the store, I need to use Vuex's mapState and mapActions.

typescript vue.js vue-router vuejs3

When working with the Options API in Vue, type inference can be improved by declaring components using the defineComponent() wrapper:

To ensure TypeScript accurately infers types within Vue component options, it's important to define components with the global method defineComponent:
import { defineComponent } from 'vue'

const Component = defineComponent({
  // Type inference is now enabled
})
If you're utilizing single-file components, this would typically be implemented as follows:
<script lang="ts">
import { defineComponent } from 'vue'

export default defineComponent({
  // Type inference is now enabled
})
</script>

Thus, your component structure should resemble something like this:

<script lang="ts">
import { defineComponent } from 'vue'
                    
export default defineComponent({
  methods: {
    async handleSubmit () {
      // ✅
      this.$router.push('/')
    }
  }
})
</script>

Alternatively, another approach is to utilize useRouter() within the Composition API:

<script lang="ts">
import { ref, defineComponent } from 'vue'
import { useRouter } from 'vue-router'

export default defineComponent({
  setup() {
    const router = useRouter()
    const handleSubmit = async () => {
      router.push('/')
    }

    return { handleSubmit }
  }
})
</script>

Did you happen to overlook setting the router-view --> tag in App.vue within your template? This is necessary for rendering your component data into your router. Remember to utilize this.$router.push({ path: 'your router path' }) in your method as well.
