vue webpack v1 & v2 基础配置篇（初学者--1）

Webpack现在有v1和v2两种版本。

1. 安装nodejs。这就不细说了，度娘告诉你。

2. cmd定位到开发文件夹，按照提示生成package.json。npm init

3. 安装es6编译插件。$ npm install css-loader babel-loader babel-core babel-preset-es2015 --save-dev

4. 安装webpack。$ npm install webpack html-webpack-plugin extract-text-webpack-plugin vue-template-compiler --save-dev
   如果是v2版本，还需npm install --save-dev extract-text-webpack-plugin@beta

5. 安装vue，vuex。$ npm install vue vuex

6. 配置webpack.config.js。参考文章最后的代码。

7. run webpack。$ webpack

//webpack v1
var webpack = require('webpack');
var HtmlWebpackPlugin = require('html-webpack-plugin');
var ExtractTextPlugin = require('extract-text-webpack-plugin');

module.exports = {
    entry: {
        app: './app.js', //入口js
        vendors: [
            'vue', 'vuex' //单独抽出vue，vuex打包成一个js
        ]
    },
    output: {
        path: 'dist',
        filename: '[name].js'
    },
    resolve: {
        extensions: ['', '.js', '.css', '.vue']

        ]
    },

        loaders: {
            css: ExtractTextPlugin.extract("css")
        }
    },
    babel: { //es6转为es5代码
        presets: ['es2015'],
        plugins: ['transform-runtime'] //这个必须install babel-plugin-transform-runtime
    },
