这篇随笔会陆续地更新下去,用于汇集一些关于Webpack的初学跳坑总结还有VueJS的基础知识。
Webpack部分
① 快速建立一个Webpack-Vue项目开发环境(4.36.1-2019/08/07)
Step 1 安装 Webpack:
COPY
EXPAND
COPY
EXPAND
Step 2 Webpack 4 需要再安装 Webpack-Cli:
COPY
EXPAND
npm install webpack-cli -g |
COPY
EXPAND
Step 3 快速初始化一个Vue项目
COPY
EXPAND
COPY
EXPAND
安装Vue和Webpack-dev-server
vue@2.6.10
webpack-cli@3.3.6
webpack-dev-server@3.7.2
COPY
EXPAND
COPY
EXPAND
这里安装webpack-dev-server,目的是方便调试,其热加载工具可以侦测项目文件夹下的文件变动,相应地进行自动刷新,当然,还需要手动配置,后面会讲到。
COPY
EXPAND
npm install webpack-dev-server --save |
COPY
EXPAND
项目文件夹下安装,webpack,webpack-cli
COPY
EXPAND
npm install webpack --save |
COPY
EXPAND
webpack现在的版本需要这样安装webpack-cli
COPY
EXPAND
npm install -D webpack-cli --save |
COPY
EXPAND
安装vue-loader,同时还要安装vue-template-complier
COPY
EXPAND
npm install vue-loader vue-template-compiler --save |
COPY
EXPAND
Step 4 开始动工一个项目
创建文件夹目录和文件,例如项目根目录叫做webpack-test,其下创建2个文件夹:dist/、src/,创建3个文件:index.html、packge.json、webpack.config.js,src/下创建main.js、templates/以及templates/main.vue,具体文件关系如下图:
按照如下编辑文件内容:
index.html

Step 5 webpack 使用
先运行打包看看:
COPY
EXPAND
COPY
EXPAND
之后便在 dist/ 下打包好一个 build.js 文件
开发模式,热加载,很方便,一旦它监测文件更改,便会热加载,解放了键盘刷新操作,很省心。
COPY
EXPAND
COPY
EXPAND
之后会开启一个webpack-dev服务,然后默认浏览器跳转到 localhost 页面,不出意外,屏幕上已经打印出了 Hello, Vue! :
