当我们执行npm run start的时候实际上执行的是package.json中的scripts下的脚本命令,此时npm会新建一个shell并将当前目录的node_mo...
一、去node_modules中找找 命令行相关脚本 1. 根据npm知识,命令行相关代码都是bin目录下的。 只有一个react-scripts.js文件 2. 继续打开react-scripts.js文件: 可以看到是会根据不同的指令,去打开../scripts/目录下的对应文件 3. 去到/scripts目录下看看: image.png 4. 打开build.js文件: 可以看到是读取web...
"scripts":{"start":"react-scripts start",//npmstart"build":"react-scripts build","test":"react-scripts test","eject":"react-scripts eject"}, 从上面代码中可以看出执行npm start 命令时,运行的是react-scripts start,由此可见react-scripts 这个库,是启动这个项目的核心,它这里封装了些什么呢? 从.b...
"scripts":{"build":"webpack --config build/webpack.common.js --mode production"}复制代码 这样的webpack简单的打包功能就有了。 Bable Bable这里使用的是7版本,与之前版本不同的是安装依赖时的包名,像babel-core、babel-preset-env、babel-polyfill等,名字已经更换成了@babel/core、@babel/preset-env、@ba...
所以执行的是 react-scripts start 打开你的my-app\node_modules\react-scripts这个文件夹下的bin文件夹下的react-scripts.js文件 #!/usr/bin/env nodevarspawn = require('cross-spawn');varscript = process.argv[2];varargs = process.argv.slice(3);switch(script) {case'build':case'eject':case'start...
下载完成后,打开文件 react-scripts/bin/react-scripts.js 该文件主要解析参数并执行对应的 .js 文件 // 跨平台的spawn const spawn = require('react-dev-utils/crossSpawn'); // 获取构建命令参数 如start、build、test、eject const args = process.argv.slice(2); const scriptIndex = args.findIndex(...
"build":"react-scripts build", If it makes proper build with proper module bundler rules then it will run or else it will keep throwing errors.
"scripts": { "start": "react-scripts start", "build": "react-scripts build", "test": "react-scripts test", "eject": "react-scripts eject" } 5. 配置Webpack React项目使用Webpack来打包资源。你可以在config/webpack.config.js文件中自定义Webpack配置。 6. 配置Babel Babel用于将ES6+代码转换...
"build": "react-scripts build", "test": "react-scripts test", "eject": "react-scripts eject" }, // coding } 在命令行中执行npm run start时,相当于执行react-scripts start,在安装react-scripts库时,rect-scripts命令同时会在node_modules/bin中生成 ...
