What is the best way to trigger a localstorage change event using Vue.js?

I'm currently facing an issue with my Vue app related to updating user information stored in localStorage. I've implemented a solution using websockets in App.vue within the mounted function, as shown below:

window.Echo.channel("user." + this.userData.id).listen(".user-updated", (user) => {
              localStorage.setItem('userData', JSON.stringify(user.user))
        });

While the real-time update of localStorage is working fine, the challenge lies in ensuring that all components display the updated information without requiring the user to refresh the page or switch routes.

Is there a method to simultaneously update all components from App.vue?

Answer №1

To trigger events, you have the option of utilizing an event bus or employing Vuex. Here is a demonstration:

window.Echo.channel("user." + this.userData.id).listen(".user-updated", (user) => {
              localStorage.setItem('userData', JSON.stringify(user.user));

              //trigger event
              EventBus.$emit('EVENT_USER_DATA_CHANGE', payLoad);
        });

Subsequently, in other components:

 mounted () {
    EventBus.$on(‘ EVENT_USER_DATA_CHANGE’, function (payLoad) {
      ...
    });
  }

To enable re-rendering, implement :key binding on the body or main container element. For example, you can use

<main :key="pageTrigger">

. Within your listening function, update the pageTrigger with new Date().getTime() to trigger a re-render of the components within the container.

If you are utilizing vuex as well, consider storing the pageTrigger in the store so that it can be accessed from any part of your application.
