  • How to Install Go and Set Up Your Development Environment

    In our first post, we covered what Go is and the top reasons why you should learn it in 2025. Now, it’s time to stop talking and start doing.

    Today is all about getting your hands dirty. We will walk through every step of installing Go and configuring a professional-grade development environment on your computer. By the end of this article, you’ll be ready to write your first line of Go code.

    Let’s get started!


    Step 1: Download and Install Go

    First, we need to install the official Go toolchain, which includes the compiler, standard libraries, and command-line tools.

    Head over to the official Go downloads page:

    ➡️ Official Go Downloads Page (go.dev)

    Here you will find installers for all major operating systems. Select the one for your machine.

    For Windows Users

    1. Download the MSI installer (e.g., go1.2x.x.windows-amd64.msi).
    2. Double-click the downloaded file to run the installer.
    3. Follow the prompts. The installer will place Go in C:\Program Files\Go and automatically add the C:\Program Files\Go\bin directory to your system’s PATH environment variable. This is important as it lets you run Go commands from any terminal.

    For macOS Users

    1. Download the package installer (e.g., go1.2x.x.darwin-amd64.pkg).
    2. Open the downloaded file and follow the installation wizard. It will install Go in /usr/local/go and add /usr/local/go/bin to your PATH.
    3. (Alternative for Developers): If you use Homebrew, you can simply open your Terminal and run: brew install go.

    For Linux Users

    1. Download the tarball archive (e.g., go1.2x.x.linux-amd64.tar.gz).
    2. Open your terminal.
    3. It’s standard practice to install Go in /usr/local. Run the following command to extract the archive there (you may need sudo):Bash# Make sure to remove any previous installation first sudo rm -rf /usr/local/go # Replace the filename with the one you downloaded sudo tar -C /usr/local -xzf go1.2x.x.linux-amd64.tar.gz
    4. Next, add the Go binary path to your environment. Add the following line to your $HOME/.profile or $HOME/.bashrc file:Bashexport PATH=$PATH:/usr/local/go/bin
    5. Apply the changes by running source $HOME/.profile or by opening a new terminal window.

    Step 2: Verify Your Installation

    This is a critical step to ensure everything worked correctly. Open a new terminal (Command Prompt or PowerShell on Windows, Terminal on macOS/Linux) and type the following command:

    Bash

    go version
    

    You should see output similar to this, confirming that Go is installed:

    go version go1.24.0 windows/amd64 
    

    (Your version number and OS may be different)


    Step 3: Set Up Your Code Editor (VS Code)

    While you can write Go code in any text editor, using a modern code editor with good language support will make your life much easier. We highly recommend Visual Studio Code (VS Code). It’s free, powerful, and has fantastic Go support.

    1. Download VS Code: If you don’t already have it, download it from the official site: https://code.visualstudio.com/
    2. Install the Go Extension: Once VS Code is installed, you need to add the official Go extension.
      • Open VS Code.
      • Go to the Extensions view (click the icon on the left sidebar or press Ctrl+Shift+X).
      • Search for “Go”.
      • Install the one published by the “Go Team at Google”.
      ➡️ Direct Link: Go Extension for VS Code
    3. Install Go Tools: The first time you open a .go file, the extension will prompt you in the bottom-right corner to install additional Go analysis tools. Click “Install All”. These tools are essential for features like auto-completion, code navigation, and error checking.

    Excellent. Let’s move on to the second day. This post is crucial as it involves getting the user’s system ready for coding. Clear, step-by-step instructions with links are key.

    Here is the draft for your Day 2 blog post.
