vue制作toast组件npm包示例代码

之前写了一个ui组件，但是感觉没必要的东西太多了，所以做了一下优化

介绍

之前制作的小组件是用webpack-simple搭建的，但是左思右想感觉没必要的东西太多太多，所以又写了一个清洁版的，直接开整

开始

建立一个空文件夹， 然后直接终端运行 npm init
建立完之后会生成一个 package.json 文件，内容如下

注意：name是之后要发的npm包的名字 不要重名，建议去npm先搜一下有没有在取

接下来对 package.json 文件添加所需模块,

{
 "name": "sever-ui",
 "version": "1.0.0",
 "description": "一个移动端ui小组件",
 "main": "index.js",
 "scripts": {
  "test": "echo \"Error: no test specified\" && exit 1",
  "start": "webpack-dev-server --hot --inline",
  "build": "webpack --display-error-details --config webpack.config.js"
 },
 "author": "sever27",
 "license": "ISC",

 "devDependencies": {
    "babel-core": "^6.26.0",
    "babel-loader": "^7.1.2",
    "babel-plugin-transform-object-rest-spread": "^6.26.0",
    "babel-plugin-transform-runtime": "^6.23.0",
    "babel-polyfill": "^6.26.0",
    "babel-preset-es2015": "^6.24.1",
    "css-loader": "^0.28.7",
    "es6-promise": "^4.1.1",
    "vue": "^2.5.9",
    "vue-hot-reload-api": "^2.2.4",
    "vue-html-loader": "^1.2.4",
    "vue-style-loader": "^3.0.3",
    "vue-template-compiler": "^2.5.9",
    "webpack": "^3.9.1",
    "webpack-dev-server": "^2.9.5"
 }
}

配置修改完成之后 终端运行 npm install 安装依赖。

接着在目录下创建文件夹 src及文件等，这是我的目录结构

对应文件内容
src/main.vue

<template>
 <div v-if="visible" class="sever-toast">
   <span class="toast-msg" >{{msg}}</span>
 </div>
</template>
<script>
export default {
 name:"sever-toast",
 data(){
  return {
   visible:false,
   msg:'默认值',
   duration:'3000',
  }
 },
 methods:{
  close(){
   setTimeout(() => {
    this.visible = false;
   }, this.duration);

  }
 },
 mounted(){
 }
}
</script>
<style >
 .sever-toast{
  display: flex;
  justify-content: center;
  align-items: center;
  height: 100%;
  position: fixed;
  top:0;
  bottom:0;
  left:0;
  right:0;
 }
 .toast-msg{
  color: #ffffff;
  background:rgba(0,0,0,0.5);
  padding:0.3rem;
  border-radius: 0.1rem;
  font-size: 0.34rem;
 }
</style>

src/main.js

import Vue from 'vue';
import Main from './main.vue'
let MmToast = Vue.extend(Main);

let instance ;

const Toast = function(options) {
 instance = new MmToast({
  data: options
 });
 instance.$mount();
 document.body.appendChild(instance.$el);
 instance.visible = true;

 return instance.close()
}

export default Toast

Toast/index.js

import Toast from './src/main.js'
export default Toast

index.js

import Toast from './Toast/index.js' 

const install = function(Vue) {

 Vue.prototype.$toast = Toast

}
console.log(typeof window !== 'undefined' , window.Vue)

if (typeof window !== 'undefined' && window.Vue) {
 install(window.Vue);
}

export default {
 install,
 Toast,
}

接下来修改webpack.dev.conf.js

const path = require("path");
const webpack = require("webpack");
const uglify = require("uglifyjs-webpack-plugin");

module.exports = {
  devtool: 'source-map',
  entry: "./src/index.js",//入口文件，src目录下的index.js文件，
  output: {
    path: path.resolve(__dirname, './dist'),//输出路径，就是新建的dist目录，
    publicPath: '/dist/',
    filename: 'sever-ui.min.js',
    libraryTarget: 'umd',
    umdNamedDefine: true
  },
  module: {
    rules: [{
        test: /\.vue$/,
        loader: 'vue-loader'
      },
      {
        test: /\.less$/,
        use: [
          { loader: "style-loader" },
          { loader: "css-loader" },
          { loader: "less-loader" }
        ]
      },
      {
        test: /\.js$/,
        exclude: /node_modules|vue\/dist|vue-router\/|vue-loader\/|vue-hot-reload-api\//,
        loader: 'babel-loader'
      },
      {
        test: /\.(png|jpg|gif|ttf|svg|woff|eot)$/,
        loader: 'url-loader',
        query: {
          limit: 30000,
          name: '[name].[ext]?[hash]'
        }
      }
    ]
  },
  plugins: [
    new webpack.DefinePlugin({
      "process.env": {
        NODE_ENV: JSON.stringify("production")
      }
    })
  ]
}

好了 一个简单的toast组件已经完成了
接下来是打包 执行 npm run build 生成文件

接着修改package.json

"main":"./dist/sever-ui.min.js",

然后我们就可以上传到npm了
执行

npm login
npm publish

接下来让我们看看效果

npm install sever-ui

引入

<template>
 <div class="home">
  <div @click="Toast()">点击Toast</div>
 </div>
</template>

<script>

export default {
 name: 'Home',
 components: {
 },
 methods:{
  Toast(){
   this.$toast({msg:'哈哈哈哈哈哈'})
  }
 }
}
</script>

修改

优化

只是一个toast感觉直接输入内容，所以做了一下修改
main.js

import Vue from 'vue';
import Main from './main.vue'
let MmToast = Vue.extend(Main);

let instance ;

const Toast = function(options) {
 if( typeof options === 'string'){
  options = {
   msg:options
  }
 }
 instance = new MmToast({
  data: options
 });
 instance.$mount();
 document.body.appendChild(instance.$el);
 instance.visible = true;

 return instance.close()
}

export default Toast

这样 就可以直接使用 this.$toast('toast内容')
