webpack2.0+ vue2.0

Posted 2020-09-05 W+7

一 webpack 2.0 及用到的插件安装（默认已经有node环境）

1. package.json文件 （插件安装及插件的功能不详解）

{
  "private": true,
  "devDependencies": {
    "autoprefixer-loader": "^3.2.0",
    "babel-core": "^6.18.2",
    "babel-loader": "^6.2.7",
    "babel-plugin-transform-runtime": "^6.15.0",
    "babel-preset-es2015": "^6.18.0",
    "babel-preset-stage-0": "^6.16.0",
    "babel-runtime": "^5.8.38",
    "clean-webpack-plugin": "^0.1.15",
    "css-loader": "^0.25.0",
    "debug": "^2.2.0",
    "express": "^4.14.0",
    "extract-text-webpack-plugin": "^2.0.0",
    "file-loader": "^0.9.0",
    "html-webpack-plugin": "^2.24.1",
    "node-sass": "^4.5.0",
    "postcss-loader": "^1.3.2",
    "sass-loader": "^6.0.2",
    "style-loader": "^0.13.1",
    "url-loader": "^0.5.7",
    "vue-hot-reload-api": "^1.2.0",
    "vue-html-loader": "^1.2.3",
    "vue-loader": "^7.3.0",
    "vue-resource": "^1.2.1",
    "webpack": "^2.2.1",
    "webpack-dev-middleware": "^1.8.4",
    "webpack-dev-server": "^1.16.2",
    "webpack-hot-middleware": "^2.13.1"
  },
  "dependencies": {
    "vue": "^2.0.0",
    "vue-router": "^2.0.0"
  },
  "scripts": {
    "build": "webpack --display-modules --display-chunks --config webpack.prod.config.js",
    "dev": "cross-env webpack --hide-modules --display-chunks --config webpack.dev.config.js",
    "test": "cross-env webpack  --config webpack.config.js"
  }
}

注明：scripts 设置了一些执行的命令 如dev 就是执行dev环境下webpack编译用的命令 控制台之行：npm run dev即可

2.webpack  配置文件 （有些配置的路径 按项目改变）

（1）webpack.config.js

var path = require(\'path\');
var webpack = require(\'webpack\');
var ExtractTextPlugin = require(\'extract-text-webpack-plugin\');
module.exports = {
    /* 输入文件 */
    entry:  {
        // path.resolve([from ...], to) 将to参数解析为绝对路径
        index:path.resolve(__dirname, \'./resources/js/src/index.js\'),
        // 需要被提取为公共模块的群组
        vendors:[\'vue\',\'vue-router\',\'three\',\'convex\'],
    },
    output: {
        /* 输出目录，没有则新建 */
        path: path.resolve(__dirname, \'./public/js/\'),
        /* 静态目录，可以直接从这里取文件 */
        //publicPath: \'./resources/js/dist/\',
        /* 文件名 */
        filename: \'[name].[hash].js\',
    },
    resolve:{
      extensions: [\'.js\', \'.css\', \'.scss\',\'.vue\'],
      alias: {
        \'vue$\': path.resolve(__dirname,\'./node_modules/vue/dist/vue.js\'),
        \'vue-router$\':path.resolve(__dirname,\'./node_modules/vue-router/dist/vue-router.js\'),
        \'three$\':path.resolve(__dirname,\'./resources/js/lib/threejs/build/three.min.js\'),
        \'convex$\':path.resolve(__dirname,\'./resources/js/lib/convex.js\'),
      }
    },
    module: {
        rules: [
            /* 用来解析vue后缀的文件 */
            {
                test: /\\.vue$/,
                use: [\'vue-loader\']
            },
            /* 用babel来解析js文件并把es6的语法转换成浏览器认识的语法 */
            {
                test: /\\.js$/,
                loader: \'babel-loader\',
                /* 排除模块安装目录的文件 */
                exclude: /node_modules/,
                options:{
                    presets: [\'es2015\', \'stage-0\'],  
                    plugins: [\'transform-runtime\']                      
                }
            },
            {  
                test: /\\.css$/,                  
                // 将样式抽取出来为独立的文件
                loader: ExtractTextPlugin.extract({fallback:"style-loader", use:["css-loader","postcss-loader"]}),
                exclude: /node_modules/
            },
            // 使用less-loader、autoprefixer-loader、css-loader和style-loade 加载 .less 结尾的文件
            {  
                test: /\\.scss$/,                  
                // 将样式抽取出来为独立的文件
                use:[\'style-loader\',\'css-loader\',\'autoprefixerx\',\'sass-loader\'], 
                exclude: /node_modules/
            },           
            // 加载图片
            {
                test: /\\.(png|jpg|gif)$/,
                loader: \'url-loader\',
                options: {
                    // 把较小的图片转换成base64的字符串内嵌在生成的js文件里
                    limit: 10000,
                    // 路径和生产环境下的不同，要与修改后的publickPath相结合
                    name: \'img/[name].[ext]?[hash:7]\'
                }
            },
            // 加载图标
            {
                test: /\\.(eot|woff|woff2|svg|ttf)([\\?]?.*)$/,
                loader: \'file-loader\',
                options: {                   
                    limit: 10000,
                    // 路径和生产环境下的不同，要与修改后的publickPath相结合
                    name:\'fonts/[name].[ext]?[hash:7]\',
                    prefix:\'font\'
                }
            }
        ]
    },
    //devtool: \'#eval-source-map\',
}

注明：webpack2.0中loader名称要补全 如sass－loader 之前可以省略－loader这样的后缀 但是现在必须写全 否则无法编译

2.webpack.dev.conifg.js

// 引入依赖模块
var path = require(\'path\');
var webpack = require(\'webpack\');
var HtmlWebpackPlugin = require(\'html-webpack-plugin\');
var ExtractTextPlugin = require(\'extract-text-webpack-plugin\');
var CleanWebpackPlugin = require(\'clean-webpack-plugin\');

// 引入基本配置
var config = require(\'./webpack.config.js\');

// 必须修改原配置中网站运行时的访问路径，相当于绝对路径，修改完之后，当前配置文件下的很多相对路径都是相对于这个来设定；
// 注意：webpack-dev-server会实时的编译，但是最后的编译的文件并没有输出到目标文件夹，而是保存到了内存当中
config.output.publicPath = \'/game/laravel-master/public/js/\';

// 重新配置插件项
config.plugins = [
    // 位于开发环境下
    new webpack.DefinePlugin({
        \'process.env\': {
            NODE_ENV: \'"development"\'
        }
    }),
    // 自动生成html插件，如果创建多个HtmlWebpackPlugin的实例，就会生成多个页面
    new HtmlWebpackPlugin({
        // 生成html文件的名字，路径和生产环境下的不同，要与修改后的publickPath相结合，否则开启服务器后页面空白
        filename: \'../../resources/views/dist/index.blade.php\',
        // 源文件，路径相对于本文件所在的位置
        template: path.resolve(__dirname, \'./resources/views/index.blade.php\'),
        // 需要引入entry里面的哪几个入口，如果entry里有公共模块，记住一定要引入
        chunks: [\'vendors\',\'index\'],
        // 要把<script>标签插入到页面哪个标签里(body|true|head|false)
        inject: \'body\',
        // 生成html文件的标题
        title:\'\'
        // hash如果为true，将添加hash到所有包含的脚本和css文件，对于解除cache很有用
        // minify用于压缩html文件，其中的removeComments:true用于移除html中的注释，collapseWhitespace:true用于删除空白符与换行符
    }),    

    // 提取css单文件的名字，路径和生产环境下的不同，要与修改后的publickPath相结合
    new ExtractTextPlugin("[name].[contenthash].css"),    

    // 提取入口文件里面的公共模块
    new webpack.optimize.CommonsChunkPlugin({
        name: \'vendors\',
        filename: \'vendors.js\',
    }),  

   
    new CleanWebpackPlugin([\'js\',\'views\',\'css\'],{
        root:path.resolve(__dirname, \'./public/\'),
        verbose: true,
        dry: false,
        //exclude: [\'shared.js\']
    }),  
    new CleanWebpackPlugin([\'views/dist\'],{
        root:path.resolve(__dirname, \'./resources/\'),
        verbose: true,
        dry: false,
        //exclude: [\'shared.js\']
    }), 
    // 为组件分配ID，通过这个插件webpack可以分析和优先考虑使用最多的模块，并为它们分配最小的ID
    //new webpack.optimize.OccurenceOrderPlugin(),

    // 模块热替换插件
    //new webpack.HotModuleReplacementPlugin(),

    // 允许错误不打断程序
    //new webpack.NoErrorsPlugin(),

    // 全局挂载插件
    new webpack.ProvidePlugin({
        Vue: "vue",
        THREE:\'three\'
    })        
];

module.exports = config;

注明：HtmlWebpackPlugin inject 最好还是配置为body 会规避一些问题 （如 渲染速度 加载时序等）

二 vue项目

1。项目结构  （用的laravel php框架 webpack中的部分路径与该项目结构一致）

2.看下主视图文件 index.blade.php （这个文件由于用的laravel框架 目前没找到怎么改后缀名）

<!DOCTYPE html>
<html>
    <head>
        <title>Laravel</title>
        <meta http-equiv="content-type" content="text/html; charset=UTF-8" />
    </head>
    <body>
        <div id="app">

        </div>
        
    <script type="text/javascript" src="/game/laravel-master/public/js/vendors.js"></script><script type="text/javascript" src="/game/laravel-master/public/js/index.f6c1bc018a4da91a571e.js"></script></body>
</html>

注明：视图文件 什么都没做 就放一个用于vue实例挂载的元素 js文件也是用webpack编译后插入的

3. resources - js - src -index.js 项目的入口文件（es6语法）

import App from \'./pages/app.vue\';
import VueRouter from \'vue-router\';
import VueResource from \'vue-resource\';

Vue.use(VueRouter);
Vue.use(VueResource);


const main = resolve => {
    require.ensure([\'./pages/main.vue\'],()=>{
        resolve(require(\'./pages/main.vue\'))
    })
}


const router = new VueRouter({
  routes: [{
          path:\'/page\',
          component: main,
      }
  ]
})


Vue.http.options.emulateJSON = true;

Vue.http.interceptors.push((request, next)  =>{


    next((response) => {
        return response
    });
   
});

const app = new Vue({
  router:router,
  render: h => h(App),
}).$mount(\'#app\')

 注明：创建了Vue实例并挂载在id为app的元素上，并创建了一个简单的路由实例 

4.app.vue 文件 什么也没做 就是使用<router-view></router-view>标签，它用于渲染匹配的组件 和 加载一个common.scss文件设置一些页面全局样式

<template>
<router-view></router-view>
</template>

<script>
export default {
components: {

}
}
</script>

<style scoped lang=\'sass-loader\'>
@import \'../../../css/src/common.scss\';
</style>

5.main.vue  基本上写了单页面组件所有能用到常用属性 

<template>
    <div class="data-webgl-main" ref="canvasbox">
        <canvas ref="canvas"></canvas>
    </div>
</template>

<script >


    export default{
　　    //监听父传递的变量和函数
        props:[
        ],
　　　　 //声明用到组件
        components:{

        },
　　　　//组建的数据
        data () {
            return {
                vinit:\'\',
                vscene:\'\',
                vcamera:\'\',
                vrenderer:\'\',
                vlight:\'\',
                vgeometry:\'\',
                vmaterial:\'\',
                vcube: \'\',
                vsphere:\'\',
                vline:\'\',
                vspGroup:\'\',
                vhullMesh:\'\',
                vcloud:\'\'

            }
        },
　　　　//组建加载完执行
        mounted (){
            this.vscene = new THREE.Scene();
            this.vcamera = new THREE.PerspectiveCamera(45, window.innerWidth/window.innerHeight, 0.1, 1000);
            this.vrenderer = new THREE.WebGLRenderer({canvas:this.$refs.canvas,antialias : true});
            
            this.finitRender();
            this.finitCamera();
            this.finitScene();
            this.finitLight();

            //this.fgeneratePoints();
            this.fcreatePointCloud(3,true,0.6,true, 0xffffff);
            this.frender();
        },
　　　　//组建被创建触发
        created () {
            
        },
        //监听路由和一些变量的变化出发 监听函数要注意 this的指向
        watch:{

        },
        //组建用到的所有方法
        methods:{
            frender (){
                // this.vrenderer.clear();
                // this.vcamera.position.x  = this.vcamera.position.x  + 1;

    //             this.vhullMesh.rotation.y += 0.01;

                var vertices = this.vcloud.geometry.vertices;
                vertices.forEach(function (v) {
                    v.y = v.y - (v.velocityY);
                    v.x = v.x - (v.velocityX);

                    if (v.y <= 0) v.y = 60;
                    if (v.x <= -20 || v.x >= 20) v.velocityX = v.velocityX * -1;
                });
                this.vrenderer.render(this.vscene, this.vcamera);
                requestAnimationFrame(this.frender);
