vue制作一个ui组件npm包

• 介绍

• • 优化

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')
