If we know how to create Vue web apps but want to develop mobile apps, we can use the Ionic framework.

In this article, we’ll look at how to get started with mobile development with the Ionic framework with Vue.

Toggle Switches

We can add toggle switches with the ion-toggle component.

For example, we can add switches with various colors:

<template>
  <div>
    <ion-toggle color="primary"></ion-toggle>
    <ion-toggle color="secondary"></ion-toggle>
    <ion-toggle color="danger"></ion-toggle>
    <ion-toggle color="light"></ion-toggle>
    <ion-toggle color="dark"></ion-toggle>
  </div>
</template>

<script>
import { IonLabel, IonList, IonItem, IonToggle } from "@ionic/vue";
import { defineComponent, ref, vue } from "vue";

export default defineComponent({
  components: { IonLabel, IonList, IonItem, IonToggle }
});
</script>

Also, we can write:

<template>
  <ion-item>
    <ion-label>Mushrooms</ion-label>
    <ion-toggle
      @ionChange="checked.value = !checked.value"
      value="mushrooms"
      :checked="checked"
    >
    </ion-toggle>
  </ion-item>
</template>

<script>
import { IonLabel, IonList, IonItem, IonToggle } from "@ionic/vue";
import { defineComponent, ref, vue } from "vue";

export default defineComponent({
  components: { IonLabel, IonList, IonItem, IonToggle },
  setup() {
    const checked = ref(false);
    return { checked };
  },
});
</script>

to set a reactive property when we toggle the value.

Toolbar

We can add a toolbar with the ion-toolbar component.

For instance, we can write:

<template>
  <ion-toolbar color="dark">
    <ion-buttons slot="secondary">
      <ion-button>
        <ion-icon slot="icon-only" :icon="personCircle"></ion-icon>
      </ion-button>
      <ion-button>
        <ion-icon slot="icon-only" :icon="search"></ion-icon>
      </ion-button>
    </ion-buttons>
    <ion-buttons slot="primary">
      <ion-button color="danger">
        <ion-icon
          slot="icon-only"
          :ios="ellipsisHorizontal"
          :md="ellipsisVertical"
        ></ion-icon>
      </ion-button>
    </ion-buttons>
    <ion-title>Dark Toolbar</ion-title>
  </ion-toolbar>
</template>

<script>
import {
  IonButton,
  IonButtons,
  IonIcon,
  IonTitle,
  IonToolbar,
} from "@ionic/vue";
import {
  ellipsisHorizontal,
  ellipsisVertical,
  helpCircle,
  personCircle,
  search,
  star,
} from "ionicons/icons";
import { defineComponent } from "vue";

export default defineComponent({
  components: {
    IonButton,
    IonButtons,
    IonIcon,
    IonTitle,
    IonToolbar,
  },
  setup() {
    return {
      ellipsisHorizontal,
      ellipsisVertical,
      helpCircle,
      personCircle,
      search,
      star,
    };
  },
});
</script>

to add a dark toolbar with some buttons inside it.

ion-title has the title of the toolbar, which is displayed on the left side.

Header

We can add a header with various styles.

For example, we can write:

<template>
  <ion-header>
    <ion-toolbar>
      <ion-buttons slot="start">
        <ion-back-button></ion-back-button>
      </ion-buttons>
      <ion-title>Navigation Bar</ion-title>
    </ion-toolbar>

    <ion-toolbar>
      <ion-title>Subheader</ion-title>
    </ion-toolbar>
  </ion-header>

  <!-- Header without a border -->
  <ion-header class="ion-no-border">
    <ion-toolbar>
      <ion-title>Header - No Border</ion-title>
    </ion-toolbar>
  </ion-header>
</template>

<script>
import {
  IonBackButton,
  IonButtons,
  IonContent,
  IonHeader,
  IonTitle,
  IonToolbar
} from '@ionic/vue';
import { defineComponent } from 'vue';

export default defineComponent({
  components: {
    IonBackButton,
    IonButtons,
    IonContent,
    IonHeader,
    IonTitle,
    IonToolbar
  }
});
</script>

to add the header with a toolbar inside.

We can add the ion-no-border class to remove the border from the header.

Conclusion

We can add a toggle switch, toolbar and header with Ionic Vue.
