Vue3+TS+Vite development skills: how to develop widgets and plug-ins

Vue3 is the latest version of Vue.js. It introduces many new features and improvements, allowing developers to build flexible web applications more efficiently. In Vue3, TypeScript (TS) can be seamlessly integrated with Vue, providing us with powerful type checking capabilities. Vite is a lightweight, ES module-based development tool with fast cold start time and fast hot module updates. This article will introduce you how to use Vue3, TS and Vite for widget and plug-in development to make your application more modular and extensible.

First, we need to install Vue3 and Vite related dependencies. Open the command line tool, enter the root directory of the project, and execute the following command:

npm install vue@next
npm install -g create-vite

After the installation is complete, we can use Vite to quickly initialize a Vue3 project. Execute the following command:

create-vite my-app --template vue-ts

This will create a folder named my-app, which contains a template for a basic Vue3 project. Enter the my-app folder and execute the following command to start the project:

cd my-app
npm install
npm run dev

Now, we have successfully started a Vue3 project and can view the application in the browser.

Next, let us develop a widget to make our application more flexible. First, create a new folder in the src directory and name it widgets. Create a new Vue component in the widgets folder and name it HelloWorldWidget.vue.

In HelloWorldWidget.vue, we can define a simple HelloWorld widget:

<template>
  <div>
    <h1 id="Hello-World">Hello World!</h1>
    <p>{{ message }}</p>
  </div>
</template>

<script>
import { defineComponent } from 'vue'

export default defineComponent({
  name: 'HelloWorldWidget',
  props: {
    message: {
      type: String,
      required: true
    }
  }
})
</script>

Import and register the HelloWorldWidget component in main.ts:

import HelloWorldWidget from './widgets/HelloWorldWidget.vue'

createApp(App)
  .component('HelloWorldWidget', HelloWorldWidget)
  .mount('#app')

Run the application , we can use the HelloWorldWidget component in App.vue:

<template>
  <div id="app">
    <HelloWorldWidget message="Welcome to my app!" />
  </div>
</template>

In this way, we can easily develop and combine different widgets, thereby achieving a more flexible and reusable application structure.

In addition to widget development, we can also use Vue3, TS and Vite to develop plug-ins. Plugins are modular functionality used to extend Vue applications. Through plug-ins, we can add other functions to the application, such as data requests, state management, routing, etc.

Suppose we want to develop a plug-in called ApiPlugin to handle data requests. First, create a new folder plugins under src. Create a new TS module in the plugins folder and name it api.ts.

In api.ts, we can define a simple ApiPlugin plug-in:

import { App } from 'vue'

export default {
  install(app: App) {
    app.config.globalProperties.$api = {
      getData() {
        // 发送数据请求
      }
    }
  }
}

Import and install the ApiPlugin plug-in in main.ts:

import apiPlugin from './plugins/api'

createApp(App)
  .use(apiPlugin)
  .mount('#app')

Now, we can Access the $api object throughout the application and call the getData method to send data requests.

By using Vue3, TS and Vite for widget and plug-in development, we can make our applications more modular and extensible. With the help of Vue3's combined API, TS's type checking and Vite's rapid development features, we can build complex web applications more efficiently. I hope this article will be helpful to your Vue3 TS Vite development journey!
