is-wsl

What is is-wsl?

The is-wsl npm package is used to check if the current environment is running inside Windows Subsystem for Linux (WSL). It is a simple utility that can be used in Node.js applications to tailor behavior based on whether the code is executing in WSL or not.

What are is-wsl's main functionalities?

Detecting WSL environment

This feature allows developers to determine if their Node.js code is running inside WSL. The package exports a boolean value that is true if the environment is detected as WSL, and false otherwise. The code sample demonstrates how to use this boolean to conditionally execute code based on the environment.

const isWsl = require('is-wsl');

if (isWsl) {
  console.log('Running inside Windows Subsystem for Linux');
} else {
  console.log('Not running inside WSL');
}

Other packages similar to is-wsl

os

The 'os' package is a built-in Node.js module that provides operating system-related utility methods and properties. It does not specifically detect WSL, but it can be used to get information about the operating system which could be used in conjunction with other checks to infer if the code is running in WSL.

detect-libc

The 'detect-libc' package is used to detect the C standard library version on the system where Node.js is running. While it does not provide direct detection of WSL, it can be used to identify system-level details that might indirectly suggest the presence of WSL.

systeminformation

The 'systeminformation' package provides detailed information about the system, such as CPU, memory, disk, network, and more. It does not have a dedicated method for detecting WSL, but the comprehensive system data it provides could potentially be used to determine if the code is running in a WSL environment.

Check if the process is running inside Windows Subsystem for Linux (Bash on Windows)

Can be useful if you need to work around unimplemented or buggy features in WSL. Supports both WSL 1 and WSL 2.

Install

$ npm install is-wsl

Usage

const isWsl = require('is-wsl');

// When running inside Windows Subsystem for Linux
console.log(isWsl);
//=> true
