How to read environment variables in Node js

Question

Is there a way to read environment variables in Node.js code?

Like for example Python's os.environ['HOME'].

Answer 1

Hello @kartik,

Yes,you can read environment variables in Node.js code as:

process.env.ENV_VARIABLE

Where ENV_VARIABLE is the name of the variable you wish to access.

For example:

var mode   = process.env.NODE_ENV;
var apiKey = process.env.apiKey; 

Hope it helps!!

Thank You!!
