5 Lesser-Known Vue.js Tricks to Supercharge Your Development Workflow

5 Lesser-Known Vue.js Tricks to Supercharge Your Development Workflow

As web developers, we are always looking for ways to improve our productivity and the quality of our code. If you're a Vue.js developer, this article is for you. We're going to share some less commonly known tricks in Vue.js that can make your development workflow even more efficient.

1. Using Vue.set for Reactive Updates

In Vue.js, the reactivity system tracks changes in your data and updates the DOM accordingly. However, due to certain JavaScript limitations, Vue.js cannot detect changes made to an array using index directly or changes made to a newly added property in an object.

For such situations, `Vue.set` or `this.$set` can be used. It adds a new reactive property to an object or updates an array reactively.

  1. // add a reactive property to an object
  2. this.$set(this.user, 'age', 25);
  3.  
  4. // update an array reactively
  5. this.$set(this.array, index, newValue);

2. Inline Templates

Vue.js allows you to define your templates right within your HTML with the `inline-template` directive. This can be handy for small components, but keep in mind that your template will not have access to data or methods defined in parent scope.

  1. <div id="app" v-cloak>
  2. {{ message }}
  3. </div>
  4.  
  5. <!-- In your CSS -->
  6. [v-cloak] { display: none; }

3. Using `v-cloak` to Hide Un-compiled Templates

While your Vue.js application is loading, users might see the raw mustache syntax before it gets compiled. You can use the `v-cloak` directive to hide your Vue.js app until the compilation finishes.

  1. <div id="app" v-cloak>
  2. {{ message }}
  3. </div>
  4.  
  5. <!-- In your CSS -->
  6. [v-cloak] { display: none; }

4. Accessing Parent and Root Components

Vue.js provides a way to access the parent and root instance from a child component. You can use `this.$parent` to access the parent instance and `this.$root` to access the root instance.

  1. methods: {
  2. showParentData() {
  3. console.log(this.$parent.data);
  4. },
  5. showRootData() {
  6. console.log(this.$root.data);
  7. }
  8. }

5. Using `v-once` for Static Content

If you have parts of your application that will not change once they're rendered, like a static navbar or footer, you can use the `v-once` directive. It ensures that the content is only compiled and rendered once, which can improve the performance of your application.

  1. <div v-once>
  2. <h1>Vue.js Tricks</h1>
  3. </div>
