Exploring the implementation of `setInterval` within the scope of a particular component in Vue

Question

Exploring the implementation of `setInterval` within the scope of a particular component in Vue

How can I restrict the scope of setInterval to a specific component only in Quasar framework when using SPA mode?

Setting the function causes it to run everywhere, even when the page's URL is changed. I have already checked a similar question on Stack Overflow, but it did not provide the solution I was looking for.

Here is a snippet of my code:

methods:
  testInterval: function () {
    setInterval(() => this.playCMD(), 2000)
  },
  playCMD: function () {
    // Do something
    console.log('Do something')
  }

I am looking for a way to confine the execution of a function in VueJs to a specific scope, rather than having it run throughout the entire application when using SPA mode.

Answer №1

Although I have yet to explore the Quasar framework, here are some potential solutions you could consider:

One option is to subscribe to the 'destroyed' event in the Vue lifecycle and then implement a clearTimeout function.

Another approach is:

If you are utilizing Vue-Router, you can leverage In-Component Guards which allow you to handle events when navigating to another component. This can be utilized to execute a clearTimeout function.

 data: () => {
     return {
         timer: null
     };
 },
 methods: {
     testInterval() {
         this.timer = setInterval(this.playCMD, 2000)
     }
 },
 beforeRouteLeave (to, from, next) {
     if(this.timer)
         clearInterval(this.timer);
     next();
 }

EDIT: Thanks to @Ali Hallaji for the insightful tip - remember to include a call to the next function for smooth progression through the pipeline, as detailed here.

Big thanks to @Shoejep for the helpful solution! It's now working perfectly. We needed to insert the next() function within the beforeRouteLeave method. Check out the code snippet below:

beforeRouteLeave (to, from, next) {
    if(this.timer)
        clearInterval(this.timer)
        next()
}

It's crucial to have the next() call in order to smoothly navigate to other routes.
