如何在nodejs中为生产和开发设置不同的环境？

Question

How Will I set different environments for production and development in nodejs in current project scope only without using any module? I am working locally and want to setup different environment on localhost only.

Answer 1

Use process.env -

process.env['VARIABLE'] = value;

Also recommend to look at dotenv . Here's an article explaining it's usage - Managing environment variables in Node.js .
