NodeJS配置默认环境

Question

Is it possible to change the default environment used by config ?

The default environment is 'development' but I would like to change that to another value (in a way that also changes the configuration file load order accordingly).

Answer 1

Three options :

• Set NODE_ENV environment variable. ( eg : export NODE_ENV=prod )
• Passing env in command line ( eg : NODE_ENV=prod node myapp.js )
• Set environment directly in your code

process.env.NODE_ENV = "prod";
const config = require('config');

I recommend first option !
