问题描述

我对AWS Beanstalk部署的整体工作流程感到好奇。我假设它在某些时候运行npm以获得在服务器上安装的软件包。但我只是想知道AWS Beanstalk是否使用'npm install --production'的最新命令来安装软件包。目前我有一个如下所示的packages.json文件,如果可能的话,我想保证只安装依赖项,而不是devDependencies。

I'm curious about the overall workflow of an AWS Beanstalk deployment. I'm assuming it runs npm at some point to get the packages installed on the server(s). But I was just wondering if AWS Beanstalk uses the latest command of 'npm install --production' to install packages. Currently I have a packages.json file as shown below and would like to insure if possible that only the dependencies are being installed and not the devDependencies.

"dependencies": {
  "express": "3.4.4",
  "jade": "*",
  "restify": "~2.6.0",
  "assert": "~1.0.0",
  "orchestrate": "0.0.2",
  "chance": "~0.5.3"
}, 
"devDependencies": {
  "mocha": "~1.15.1"
}


推荐答案

目前Elastic Beanstalk环境运行 npm install 而没有 - production 标志。在导出开发人员提供的任何env自定义项(即环境选项设置)之前,会在 /opt/elasticbeanstalk/containerfiles/ebnode.py 上的实例上发生这种情况,这意味着设置EB环境中的 NODE_ENV = production 配置也不会阻止处理devDependencies。

Currently the Elastic Beanstalk environment runs npm install without the --production flag. This happens on the instance at /opt/elasticbeanstalk/containerfiles/ebnode.py before any env customizations supplied by the developer (i.e., environment option settings) are exported, which means setting NODE_ENV=production in the EB Environment's configuration also does not prevent devDependencies from being processed.
