This article provides a step-by-step guide for setting up a Vue 2 project using Vue-CLI and integrating the Syncfusion® Vue Switch component using the Composition API / Options API.

Prerequisites

System requirements for Syncfusion® Vue UI components

Dependencies

The list of dependencies required to use the Switch component in your application is given below:

|-- @syncfusion/ej2-vue-buttons
    |-- @syncfusion/ej2-base
    |-- @syncfusion/ej2-buttons
    |-- @syncfusion/ej2-vue-base

Setting up the Vue 2 project

To generate a Vue 2 project using Vue-CLI, use the vue create command. Follow these steps to install Vue CLI and create a new project:

npm install -g @vue/cli
vue create quickstart
cd quickstart
npm run serve

or

yarn global add @vue/cli
vue create quickstart
cd quickstart
yarn run serve

When creating a new project, choose the option Default ([Vue 2] babel, eslint) from the menu.

Vue 2 project

Once the quickstart project is set up with default settings, proceed to add Syncfusion® components to the project.

Add Syncfusion® Vue packages

Syncfusion® packages are available at npmjs.com. To use Vue components, install the required npm package.

This article uses the Vue Switch component as an example. Install the @syncfusion/ej2-vue-buttons package by running the following command:

npm install @syncfusion/ej2-vue-buttons --save

or

yarn add @syncfusion/ej2-vue-buttons

Import Syncfusion® CSS styles

You can import themes for the Syncfusion® Vue component in various ways, such as using CSS or SASS styles from npm packages, CDN, CRG and Theme Studio. Refer to themes topic to know more about built-in themes and different ways to refer to themes in a Vue project.

In this article, the Material theme is applied using CSS styles, which are available in installed packages. The necessary Material CSS styles for the Switch component and its dependents were imported into the <style> section of src/App.vue file.

<style>
@import "../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../node_modules/@syncfusion/ej2-buttons/styles/material.css";
</style>

Add Syncfusion® Vue component

Follow the below steps to add the Vue Switch component using Composition API or Options API:

1. First, import and register the Switch component in the script section of the src/App.vue file. If you are using the Composition API, you should add the setup attribute to the script tag to indicate that Vue will be using the Composition API.

<script setup>
import { SwitchComponent as EjsSwitch } from "@syncfusion/ej2-vue-buttons";
</script>
<script>
import { SwitchComponent } from "@syncfusion/ej2-vue-buttons";
export default {
  components: {
    'ejs-switch': SwitchComponent
  }
}
</script>

2. In the template section, define the Switch component with the checked property.

<template>
  <ejs-switch checked=true></ejs-switch>
</template

Here is the summarized code for the above steps in the src/App.vue file:

<template>
  <ejs-switch checked=true></ejs-switch>
</template>

<script setup>
import { SwitchComponent as EjsSwitch } from "@syncfusion/ej2-vue-buttons";
import { enableRipple } from '@syncfusion/ej2-base';

enableRipple(true);
</script>

<style>
@import "../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../node_modules/@syncfusion/ej2-buttons/styles/material.css";

.e-switch-wrapper {
  margin: 18px;
}
</style>
<template>
  <ejs-switch checked=true></ejs-switch>
</template>

<script>
import { SwitchComponent } from "@syncfusion/ej2-vue-buttons";
import { enableRipple } from '@syncfusion/ej2-base';

enableRipple(true);

export default {
  name: "App",
  components: {
    'ejs-switch': SwitchComponent
  }
}
</script>

<style>
@import "../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../node_modules/@syncfusion/ej2-buttons/styles/material.css";

.e-switch-wrapper {
  margin: 18px;
}
</style>

Run the project

To run the project, use the following command:

npm run serve

or

yarn run serve

Set text on Switch

Switch component has text support. This can be achieved by setting onLabel
and offLabel on Switch.

Switch does not have text support for material themes, and does not support long custom text.
