Node.js:package.json中的dependencies和devDependencies区别 dependencies和devDependencies 使用npm下载第三方类库的时候,会在package.json中生成dependencies和devDependencies。 这两种分别为: dependencies:生产依赖 devDependencies开发依赖 当我们开发项目的时候,很多工具是开发阶段使用的,比如webpack,当项目正式上线的时候,这些...
Node中容易混淆的概念 dependencies vs devDependencies dependencies是用于生产环境,需要上传到服务器的资源。 devDependencies是用于开发环境,如本地资源的打包,合并,压缩,预处理(Less to css,CoffeeScript to JavaScript)等,不要发布到生产环境 —save vs —save-dev 其实它俩就对应上面的 使用—save命令安装的就添加...

Adding dependencies: npm install lodash --save or build-time dependencies npm install babel --save-dev After npm install, it is better to npm dedupe Using NPM scripts: "script": { "start": "node index.js", "test" "mocha test", "your-custom-script": "echno npm" } Run your NPM...
打开package.json 文件,查看dependencies部分: JSON "lodash":"^1.1.0","node-fetch":"^1.0.2" 请注意,模式指定插入 (^) 符,该字符指示对次要版本的更新以支持依赖项:1.x。 打开index.js 文件,了解如何在应用中使用包依赖项: JavaScript constfetch =require('node-fetch')const_ =require...

8.5. Clean-up dependencies before production TL;DR: Although Dev-Dependencies are sometimes needed during the build and test life-cycle, eventually the image that is shipped to production should be minimal and clean from development dependencies. Doing so guarantees that only necessary code is shippe...
