vue plug-in vuejs

In front-end development, it is often necessary to use the expand and collapse function to reduce the content of the page and improve the user experience. Vue.js is a popular front-end framework that can help us easily implement the expand and collapse function. This article will introduce how to use the Vue.js plug-in to encapsulate the expand and collapse components.

1. Create a Vue.js plug-in
The process of creating a Vue.js plug-in is very simple. We will complete the creation of the plug-in in the following steps:

1. Create a. vue file and define the component

In this component, we will use written HTML code and JavaScript code to implement a UI component with two states of "expanded" and "collapsed". The overall code is as follows:

<template>
  <div>
    <div v-if="showContent">
      <slot></slot>
    </div>
    <div v-else>
      <slot name="less"></slot>
    </div>
    <button v-if="isButtonVisible" @click="toggleContent">
      {{ showContent ? buttonText.less : buttonText.more }}
    </button>
  </div>
</template>

<script>
export default {
  name: 'collapse-transition',
  props: {
    buttonText: {
      type: Object,
      default: () => ({ more: '展开', less: '收起' })
    },
    visible: {
      type: Boolean,
      default: false
    }
  },
  data() {
    return {
      showContent: this.visible,
    }
  },
  methods: {
    toggleContent() {
      this.showContent = !this.showContent;
    }
  },
  computed: {
    isButtonVisible() {
      return this.$slots.less !== undefined;
    }
  }
}
</script>
Copy after login

2. Create an index.js file to export the plug-in

In this file, we need to import the .vue file and construct it in the Vue.js Use components in functions. In this way, our component will be registered in the global scope of Vue.js.

import CollapseTransition from './CollapseTransition.vue'

const plugin = {
  install(Vue) {
    Vue.component('CollapseTransition', CollapseTransition)
  }
}

export default plugin

export { CollapseTransition }
Copy after login

3. Create a package.json file

We create an empty package.json file to serve as the configuration file for our plug-in.

{
  "name": "vue-collapse-transition-plugin",
  "version": "1.0.0",
  "description": "A Vue.js plugin for creating collapse transitions",
  "main": "dist/index.js",
  "keywords": [
    "Vue.js",
    "plugin",
    "transition",
    "collapse"
  ],
  "dependencies": {
    "vue": "^3.0.0"
  }
}
Copy after login

4. Use rollup.js to package the plug-in

We use the rollup.js tool to package the plug-in into a file. This tool can package our .vue file and index.js file into a .min.js file.

import resolve from '@rollup/plugin-node-resolve'
import commonjs from '@rollup/plugin-commonjs'
import babel from '@rollup/plugin-babel'
import { terser } from 'rollup-plugin-terser'

import pkg from './package.json'

export default {
  input: 'index.js',
  output: [
    {
      file: pkg.main,
      format: 'umd',
      name: 'VueCollapseTransition',
      plugins: [terser()]
    },
    {
      file: pkg.module,
      format: 'es'
    }
  ],
  external: ['vue'],
  plugins: [
    resolve(),
    commonjs(),
    babel({ babelHelpers: 'runtime' })
  ]
}
Copy after login

5. Publish the plug-in to the npm repository

Use the npm publish command to publish the plug-in to the npm repository to complete the plug-in release.

2. How to use plug-ins in projects
After the above steps, our plug-in has been packaged and published to the npm warehouse. We can use this plugin in any Vue.js project. Next, we will show how to use this plug-in in the project.

1. Install the plug-in

We can use the npm install/vue-cli-plugin-cypress command to install our plug-in.

npm install vue-collapse-transition-plugin
Copy after login

2. Introducing plug-ins into the Vue.js project

We introduce our plug-ins in the main.js file.

import Vue from 'vue'
import App from './App.vue'
import plugin from 'vue-collapse-transition-plugin'

Vue.config.productionTip = false

Vue.use(plugin)

new Vue({
  render: h => h(App),
}).$mount('#app')
Copy after login

3. Use components and configure parameters

We use components in the App.vue file and configure some parameters to show how this component is used in actual projects.

<template>
  <CollapseTransition :buttonText="{ more: '展开一下', less: '收起一下' }">
    <template #less>
      更多信息
    </template>
    <div>
      <ul>
        <li v-for="(item, index) in list" :key="index">{{ item }}</li>
      </ul>
    </div>
  </CollapseTransition>
</template>

<script>
import { CollapseTransition } from 'vue-collapse-transition-plugin'

export default {
  name: 'App',
  data() {
    return {
      list: ['item 1', 'item 2', 'item 3', 'item 4', 'item 5']
    }
  },
  components: {
    CollapseTransition
  }
}
</script>
Copy after login

Through this simple UI component example, we can see that the use of plug-ins is very convenient. In our actual project, we can quickly use this feature-rich UI component in just a few simple steps.

3. Summary
In this article, we learned how to use the Vue.js plug-in to encapsulate the expand and collapse UI components. By creating a Vue.js plugin and publishing it to the npm repository, we can quickly use this feature-rich UI component in any Vue.js project. Plugin development is a very important skill in Vue.js, we hope this article was helpful to you.
