Is there a way to read environment variables in Node.js code? Like for example Python's os.environ['HOME'].

 

Yes, you can read environment variables in Node.js using the process.env object. The process.env object provides access to the environment variables defined in your system or set within your Node.js application.

Here's an example of how you can read environment variables in Node.js:

javascript

// Read the value of the 'HOME' environment variable
const homeDirectory = process.env.HOME;

// Display the value
console.log('Home Directory:', homeDirectory);

In this example, process.env.HOME reads the value of the 'HOME' environment variable, which typically represents the user's home directory. You can replace 'HOME' with any other environment variable name you want to read.

Keep in mind that the availability of environment variables may vary depending on your operating system and how your Node.js application is executed. If an environment variable is not set, accessing it will return undefined. It's a good practice to check if an environment variable exists before using its value.
