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

process.env.ENV_VARIABLE 

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

See Node.js docs for process.env.

Answer 2

When using Node.js, you can retrieve environment variables by key from the process.env object:

for example

var mode   = process.env.NODE_ENV; var apiKey = process.env.apiKey; // '42348901293989849243' 

Here is the answer that will explain setting environment variables in node.js
