Before running your app, you can do this in console,

在运行你的应用程序之前，你可以在控制台，

export NODE_ENV=production

Or if you are in windows you could try this:

或者如果你在windows里你可以试试这个:

SET NODE_ENV=production

or you can run your app like this:

或者你可以这样运行你的应用:

NODE_ENV=production node app.js

You can also set it in your js file:

您还可以将其设置为js文件:

process.env.NODE_ENV = 'production';

But I don't suggest to do it in your runtime file, since it's not easy to open up VIM in your server and change it to production. You can make a config.json file in your directory and everytime your app runs, it reads from it and sets the configuration.

但我不建议在您的运行时文件中这样做，因为在您的服务器中打开VIM并将其更改为生产是不容易的。你可以做一个配置。json文件在你的目录中，每次你的应用程序运行时，它从它读取并设置配置。

in package.json:

在package.json:

{
  ...
  "scripts": {
    "start": "NODE_ENV=production node ./app"
  }
  ...
}

then run in terminal:

然后运行在终端:

npm start

export NODE_ENV=production is bad solution, it disappears after restart.

输出NODE_ENV=生产是糟糕的解决方案，重启后就会消失。

if you want not to worry about that variable anymore - add it to this file:

如果你不想再担心那个变量了，把它添加到这个文件中:

/etc/environment

don't use export syntax, just write (in new line if some content is already there):

不要使用导出语法，只需写入(如果有一些内容已经在新行中):

NODE_ENV=production

it works after restart. You will not have to re-enter export NODE_ENV=production command anymore anywhere and just use node with anything you'd like - forever, pm2...

重启后它的工作原理。您将不再需要重新输入export NODE_ENV=生产命令，只要使用您想要的任何东西——永久地，pm2…

For heroku:

heroku的:

heroku config:set NODE_ENV="production"

which is actually default.

这实际上是违约。

No one mentioned .env in here yet? Make a .env file in your app root, then require('dotenv').config() and read the values. Easily changed, easily read, cross platform.

没人提过，env在这里吗?在app根中创建一个.env文件，然后需要('dotenv').config()并读取这些值。容易改变，容易阅读，跨平台。

On OSX I'd recommend adding export NODE_ENV=development to your ~/.bash_profile and/or ~/.bashrc and/or ~/.profile.

在OSX上，我建议增加出口NODE_ENV=开发到您的~/。bash_profile和/或~ /。bashrc和/或(~ / . profile。

Personally I add that entry to my ~/.bashrc and then have the ~/.bash_profile ~/.profile import the contents of that file, so it's consistent across environments.

我个人把它添加到~/。bashrc然后是~/。bash_profile ~ /。概要文件导入该文件的内容，因此它在不同的环境中是一致的。

After making these additions, be sure to restart your terminal to pick up settings.

在做了这些添加之后，一定要重新启动你的终端以获取设置。

To not have to worry whether you are running your scripts on Windows, Mac or Linux install the cross-env package. Then you can use your scripts easily, like so:

不必担心您是否在Windows、Mac或Linux上运行您的脚本，安装跨env包。然后你可以很容易地使用你的脚本，比如:

"scripts": {
    "start-dev": "cross-env NODE_ENV=development nodemon --exec babel-node -- src/index.js",
    "start-prod": "cross-env NODE_ENV=production nodemon --exec babel-node -- src/index.js"
}

Massive props to the developers of this package.

巨大的道具给开发商的这个包裹。

Daniel has a fantastic answer which is the better approach for the correct deployment (set and forget) process.

Daniel有一个奇妙的答案，这是正确部署(设置和忘记)过程的更好方法。

For those using express. You can use grunt-express-server which is fantastic as well. https://www.npmjs.org/package/grunt-express-server
