Ionic Vue API

Ionic Vue API is a set of pre-built UI components, utilities, and services that help you rapidly build high-quality, performant apps using Vue.js and the Ionic Framework. It provides a huge list of UI components ranging from buttons, cards, forms to modals and popovers. This API includes plugins for accessing native device capabilities like camera, GPS, and Bluetooth along with a simple state management solution for managing data in your Vue.js applications.

Getting Started

To get started with Ionic Vue, you need to install the Ionic CLI and create a new project. Run the following command in your terminal:

npm install -g @ionic/cli
ionic start my-app --type vue

This will create a new Ionic Vue app with some pre-built components and a basic setup structure.

Using Components

Ionic Vue provides a wide range of UI components to build your app. You can use these components simply by importing them into your Vue component as follows:

<template>
  <ion-button>Click Me!</ion-button>
</template>

<script>
import { IonButton } from '@ionic/vue';

export default {
  components: {
    IonButton,
  },
};
</script>

This will render a button component on your app.

Using Plugins

Ionic Vue API provides a set of plugins that allow you to access native device features like Camera, Geolocation, and Bluetooth. You can add these plugins to your app using the @ionic/vue-router package.

Here is an example of using the Camera plugin to take a picture from your app:

<script>
import { useCamera } from '@ionic/vue';
import { Plugins } from '@capacitor/core';

const { Camera } = Plugins;

export default {
  setup() {
    const camera = useCamera();

    const takePicture = async () => {
      const result = await Camera.getPhoto({
        quality: 90,
        allowEditing: true,
        resultType: CameraResultType.DataUrl,
      });

      camera.photo.value = result.dataUrl;
    };

    return {
      camera,
      takePicture,
    };
  },
};
</script>

This will allow your app to access the camera and take a picture. You can use other plugins in a similar way.

State Management

Ionic Vue also provides a simple state management solution. You can use the @ionic/vue package to manage state in your Vue.js applications.

Here is an example of using the defineComponent function to create a new component to manage state:

<template>
  <ion-header>
    <ion-toolbar>
      <ion-title>{{ count }}</ion-title>
      <ion-button @click="increment">+</ion-button>
      <ion-button @click="decrement">-</ion-button>
    </ion-toolbar>
  </ion-header>
</template>

<script>
import { defineComponent } from '@ionic/vue';
import { reactive } from 'vue';

export default defineComponent({
  setup() {
    const state = reactive({
      count: 0,
    });

    const increment = () => {
      state.count++;
    };

    const decrement = () => {
      state.count--;
    };

    return {
      ...state,
      increment,
      decrement,
    };
  },
});
</script>

This will create a new component to manage increment and decrement state.

Conclusion

Ionic Vue API is a powerful and feature-rich API that can help you rapidly build high-quality apps using Vue.js and Ionic Framework. It allows you to use pre-built UI components, plugins for accessing device features, and a simple state management solution to manage data in your app.
