Setting Up Windows Subsystem for Linux (WSL) for Seamless Development

|

Introduction

In recent years, the line between Windows and Linux has blurred significantly when it comes to software development. Windows Subsystem for Linux (WSL) is one of the remarkable advancements that allows developers to run a Linux distribution alongside their Windows operating system. This integration provides a powerful and flexible environment for development, combining the best of both worlds. In this article, we will walk you through the process of setting up WSL, exploring its features, and providing coding examples to get you started on your Linux-powered Windows journey.

What is Windows Subsystem for Linux (WSL)?

Windows Subsystem for Linux, introduced by Microsoft, is a compatibility layer that enables users to run a full-fledged Linux distribution alongside their Windows installation. This means you can access a Linux terminal and run Linux applications on your Windows machine, without the need for dual booting or virtualization.

WSL brings several advantages to the table, including:

  1. Compatibility: You can use Linux-specific tools, libraries, and applications directly on Windows.
  2. Performance: Unlike traditional virtualization, WSL runs with minimal overhead, offering near-native performance.
  3. Seamless Integration: You can work on your Windows and Linux files interchangeably, eliminating the need for file synchronization.
  4. Easy Setup: Microsoft has streamlined the installation process, making it accessible to developers of all levels.

Now, let’s dive into setting up WSL on your Windows machine.

Prerequisites

Before installing WSL, ensure that you have the following:

  1. Windows 10 or higher: WSL 2 is available for Windows 10, version 1903, and later.
  2. Administrator Privileges: You need administrative access to enable WSL.
  3. Windows Subsystem for Linux Feature: Ensure that the “Windows Subsystem for Linux” feature is enabled. You can do this through the Windows Features menu.

Enabling WSL

Follow these steps to enable WSL on your Windows machine:

  1. Open PowerShell with administrator privileges. Right-click the Start button, select “Windows Terminal (Admin),” or search for “PowerShell” and choose “Run as administrator.”
  2. To enable the WSL feature, run the following command:
    bash
    dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart
  3. Now, enable the Virtual Machine Platform feature, which is required for WSL 2. Run this command:
    bash
    dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart
  4. After enabling the necessary features, restart your computer to complete the installation.

Installing a Linux Distribution

With WSL enabled, it’s time to choose and install a Linux distribution of your choice. You can select from a range of popular distributions available on the Microsoft Store, such as Ubuntu, Debian, Fedora, and more.

For this example, we’ll use Ubuntu:

  1. Open the Microsoft Store and search for “Ubuntu.”
  2. Click on the Ubuntu distribution you prefer (e.g., “Ubuntu 20.04 LTS”) and click the “Install” button.
  3. Once the installation is complete, launch the Ubuntu application from the Start menu.
  4. During the first launch, you’ll be prompted to create a user account and set a password.

Congratulations! You now have a fully functional Linux environment running on your Windows machine.

Updating and Upgrading

Before we start coding, it’s a good practice to update and upgrade the packages in your newly installed Linux distribution. Open your WSL terminal and run the following commands:

bash
sudo apt update
sudo apt upgrade

Getting Started with Coding in WSL

Now that you have WSL set up, let’s dive into some coding examples to get you started. WSL allows you to use your preferred programming languages, tools, and libraries, just as you would on a native Linux environment. Here are some examples:

Python Development

WSL makes Python development seamless. You can write Python scripts and run them within your Linux environment. Let’s create a simple “Hello, World!” Python script:

  1. Open your WSL terminal.
  2. Create a new Python file using your favorite text editor, such as Nano or Visual Studio Code. For example:
    bash
    nano hello.py
  3. Add the following code to the file:
    python
    print("Hello, World!")
  4. Save the file and exit the text editor.
  5. Run the Python script:
    bash
    python hello.py

You should see “Hello, World!” printed in your terminal.

Node.js Development

If you’re a Node.js developer, WSL provides an excellent environment for Node.js development. Let’s create a simple Node.js application:

  1. Open your WSL terminal.
  2. Create a new directory for your Node.js project and navigate into it:
    bash
    mkdir node-app
    cd node-app
  3. Initialize a new Node.js project:
    bash
    npm init -y
  4. Create a JavaScript file, e.g., app.js, and add the following code:
    javascript
    const message = "Hello, Node.js!";
    console.log(message);
  5. Run the Node.js application:
    bash
    node app.js

You should see “Hello, Node.js!” printed in your terminal.

Conclusion

Windows Subsystem for Linux (WSL) is a game-changer for developers who work in a Windows environment but require Linux capabilities. With WSL, you can seamlessly integrate Linux into your workflow, access Linux tools, and run Linux applications alongside your Windows setup. In this article, we’ve covered the installation process, basic setup, and provided coding examples to help you get started with WSL.

Whether you’re a Python enthusiast, Node.js developer, or working with other programming languages, WSL ensures a smooth development experience, combining the power of Windows and the flexibility of Linux. So go ahead, set up WSL on your Windows machine, and embark on your journey of efficient and versatile software development. Happy coding!
