最近接触一个项目,前后分离的,在启动前端的时候用到一个命令:npm run server ,感觉很神奇,直接可以让我们在浏览器中就可以访问网页或js了,很新奇,自己研究了一下,别忘记了。
首先说这是什么工具才用到的命令,网上各种搜,总结一下:
1.webpack-dev-server是一个小型的Node.js Express服务器,注意知识点:“服务器。
2.通过在package.json中配置可以通过npm命令启动,举个例子:package.json 的内容
{ "name": "ibp_static", "version": "0.0.1", "description": "ibp_static", "scripts": { "server": "webpack-dev-server --hot --inline --config webpack.server.js", "dev": "webpack-dev-server --config webpack.dev.js", "build": "webpack -p --config webpack.dev.js" }, "devDependencies": { "webpack": "3.5.5", "webpack-dev-server": "2.7.1", "extract-text-webpack-plugin": "3.0.0", "copy-webpack-plugin": "4.0.1", "clean-webpack-plugin": "0.1.16", "css-loader": "0.28.7", "file-loader": "0.11.2", "html-loader": "0.5.1", "html-webpack-plugin": "2.30.1", "html-webpack-template": "5.6.0", "raw-loader": "0.5.1", "style-loader": "0.18.2", "url-loader": "0.5.9" } }
直接打开命令行,输入 npm run dev
即可看到效果,修改文件,实现浏览器自动刷新。
