Mobile Development with Ionic and Vue — Segment Display, Dropdowns, and Toasts

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.

Segment Display

We can use the ion-segment component to add a segment display.

For example, we can write:

<template>
  <ion-segment @ionChange="segmentChanged($event)">
    <ion-segment-button value="friends">
      <ion-label>Friends</ion-label>
    </ion-segment-button>
    <ion-segment-button value="enemies">
      <ion-label>Enemies</ion-label>
    </ion-segment-button>
  </ion-segment>
</template>

<script lang="ts">
import { IonSegment, IonSegmentButton, IonToolbar } from "@ionic/vue";
import { defineComponent } from "vue";

export default defineComponent({
  components: { IonSegment, IonSegmentButton, IonToolbar },
  methods: {
    segmentChanged(ev: CustomEvent) {
      console.log("Segment changed", ev);
    },
  },
});
</script>

We add the ion-segment component to add the segment.

The ionChange event is emitted when we click on the segment.

ion-segment-button has the buttons for the segment display.

We can also change the color with the color prop:

<template>
  <ion-segment @ionChange="segmentChanged($event)" color="secondary">
    <ion-segment-button value="standard">
      <ion-label>Standard</ion-label>
    </ion-segment-button>
    <ion-segment-button value="hybrid">
      <ion-label>Hybrid</ion-label>
    </ion-segment-button>
    <ion-segment-button value="sat">
      <ion-label>Satellite</ion-label>
    </ion-segment-button>
  </ion-segment>
</template>

<script lang="ts">
import { IonSegment, IonSegmentButton, IonToolbar } from "@ionic/vue";
import { defineComponent } from "vue";

export default defineComponent({
  components: { IonSegment, IonSegmentButton, IonToolbar },
  methods: {
    segmentChanged(ev: CustomEvent) {
      console.log("Segment changed", ev);
    },
  },
});
</script>

Select Dropdown

We can add a select dropdown with the ion-select and ion-select-option components.

For example, we can write:

<template>
  <ion-list>
    <ion-item>
      <ion-label>Hair Color</ion-label>
      <ion-select value="brown" ok-text="Okay" cancel-text="Dismiss">
        <ion-select-option value="brown">Brown</ion-select-option>
        <ion-select-option value="blonde">Blonde</ion-select-option>
        <ion-select-option value="black">Black</ion-select-option>
        <ion-select-option value="red">Red</ion-select-option>
      </ion-select>
    </ion-item>
  </ion-list>
</template>

<script>
import {
  IonItem,
  IonLabel,
  IonList,
  IonListHeader,
  IonSelect,
  IonSelectOption,
} from "@ionic/vue";
import { defineComponent } from "vue";

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

We add the ion-label for the label.

ion-select is the select dropdown.

ok-text has the button for the OK text. cancel-text has the Cancel text.

ion-select-option has the option.

Toast

We can add a toast popup with Ionic Vue.

For example, we can write:

<template>
  <ion-page>
    <ion-content class="ion-padding">
      <ion-button @click="openToast">Open Toast</ion-button>
    </ion-content>
  </ion-page>
</template>

<script>
import { IonButton, IonContent, IonPage, toastController } from "@ionic/vue";

export default {
  components: { IonButton, IonContent, IonPage },
  methods: {
    async openToast() {
      const toast = await toastController.create({
        header: "Toast header",
        message: "Click to Close",
        position: "top",
        buttons: [
          {
            side: "start",
            icon: "star",
            text: "Favorite",
            handler: () => {
              console.log("Favorite clicked");
            },
          },
          {
            text: "Done",
            role: "cancel",
            handler: () => {
              console.log("Cancel clicked");
            },
          },
        ],
      });
      return toast.present();
    },
  },
};
</script>

We add a button that calls openToast when it’s clicked.

The toastController.create method creates the toast.

header has the toast header.

message has the toast message.

position has the position.

buttons have the buttons. It’s an array of objects that some options.

side has the side to put the button. start puts it on the left.

icon has the button icon.

text has the button text.

handler is a function that’s called when it’s clicked.

Conclusion

We can add segment display, select dropdowns, and toasts with Ionic Vue.
