Question

What is the best way to show database information when the route is updated?

I'm currently developing a chat application using vue.js and firebase. My goal is to retrieve certain data from the database based on the route ID and display it on the screen whenever there is a route change. However, I have encountered unexpected behavior with this data retrieval process.

Here is the section of code:

  methods: {
    getRoomName() {
      db.collection("rooms")
        .doc(this.params)
        .onSnapshot((snapshot) => (this.roomName = snapshot.data().name));
    },
  },
  watch: {
    $route(to, from) {
      this.getRoomName();
    },
  },

The data section looks like this:

data() {
    return {
      input: "",
      roomName: "",
      params: this.$route.params.id,
      message: "",
      roomNameTest: "",
    };
  },

The template includes this line of code:

<span class="roomName">{{roomName}}</span>

One of the initial observations I made is that you are trying to access this.$route within the data() method, which doesn't function as intended. To accomplish your goal of populating something, consider utilizing Vue Lifecycle Hooks.

The life cycle hooks in Vue are incredibly useful for handling different aspects of the component's lifecycle. When a Vue instance is created, the `created` hook is called, and when it is mounted onto the DOM, the `mounted` hook is triggered.

mounted() // this can also be used for the created hook {
  this.getRoomName();
},

While watchers can be effective for detecting route changes, they may not be ideal in situations where the component has not been fully instantiated at the time of the change. The `mounted` and `created` hooks are better suited for scenarios where you want to ensure that actions happen once the Vue instance is completely ready.

A watcher can be valuable for monitoring URL parameter changes and triggering specific actions based on those changes. For example, if the URL switches from `/users/1` to `/users/2`, a watcher would be able to detect this transition effectively since it operates within the same component scope.

To monitor for changes and obtain new IDs, I utilize the $route.path method.

Module

  computed: {
    ...mapState('products', ['products']),
  },
  watch: {
    '$route.path'() {
      this.bindProducts(this.IdFromUrl)
    },
  },

  mounted() {
    this.bindProducts(this.IdFromUrl)
  },

  methods: {
    ...mapActions('products', ['bindProducts']),
  }

In addition, my store has vuexfire functionality integrated. Alternatively, you have the option of binding your own data.
