Quasar Composition API with $q - Javascript

Quasar is a modern front-end framework that makes it easy to develop web applications that are responsive, fast, and beautiful. In version 2.0, Quasar introduced a new feature called the Composition API. In this article, we will explore what the Quasar Composition API is and how to use it with $q in Javascript.

What is Quasar Composition API?

The Quasar Composition API is a new way to organize and reuse your logic in Quasar applications. It is a composable and reactive way to structure code so that it is easier to reason about, test, and maintain. Essentially, the Composition API introduces a new approach to write and organize Vue.js code in Quasar applications.

What is $q in Quasar?

The $q object in Quasar is a global object that provides a range of utility functions that are commonly used in Quasar applications. These functions include things like $q.notify, $q.dialog, and $q.screen.

Using Quasar Composition API with $q in Javascript

To use Quasar Composition API with $q in Javascript, you first need to import the useQuasar function from @quasar/quasar-app-extension-composition-api/use and then call it inside your component. Here is an example:

<template>
  <div>
    <q-btn label="Notify" @click="notify">
  </div>
</template>

<script>
import { useQuasar } from '@quasar/quasar-app-extension-composition-api/use'

export default {
  setup() {
    const $q = useQuasar()

    const notify = () => {
      $q.notify({ message: 'Hello World!' })
    }

    return {
      notify
    }
  }
}
</script>

In this example, we use the useQuasar function to access the $q object, which we can then use inside the notify function to show a notification when the button is clicked. Notice that we define the notify function inside the setup function rather than in the methods property. This is because we are using the Composition API rather than the Options API.

Conclusion

The Quasar Composition API is a powerful tool that allows you to organize and reuse your logic in a composable and reactive way. Using it with $q in Javascript can make your Quasar applications more modular and easier to maintain. Give it a try in your next Quasar project!
