Git and GitHub Crash Course for Express.js Developers

#git #github #vscode #webdev

A practical guide to version control, GitHub CLI, and managing branches using Git and GitHub with Express.js projects — no fluff, just real-world workflow.

Introduction

Whether you're a beginner or working your way through a Node.js + Express.js project, using Git and GitHub is essential for version control and team collaboration. In this guide, you’ll learn how to:

  • Set up Git and GitHub from scratch
  • Use Git in the terminal
  • Use GitHub CLI to create and manage remote repositories
  • Connect your local project to GitHub
  • Create and switch between branches
  • Work with GitHub directly from your browser via GitHub.dev and VSCode.dev

This guide is hands-on and practical — no prior Git knowledge needed!

Prerequisites

Make sure you have the following installed:

  • Git (brew install git on macOS, choco install git on Windows)
  • GitHub CLI (gh)
  • A GitHub account

You can also use:

Step-by-Step Guide

1. Create or Sign In to Your GitHub Account

If you don’t already have a GitHub account, sign up here. This will allow you to push your code to the cloud and collaborate with others.

2. Open VSCode.dev or GitHub.dev

  • Visit https://vscode.dev for a blank editor
  • Or go to any GitHub repo and press . to open github.dev (web-based IDE)

Great for quick edits without local setup.

3. Initialize Git in Your Local Project

Navigate to your Express project folder and run:

git init
Enter fullscreen mode Exit fullscreen mode

This sets up a .git directory and prepares your project for version control.

4. Configure Git Author Info

Set your username and email. You can use --local (for this project) or --global (applies to all repos):

git config --local user.name "Your Name"
git config --local user.email "you@example.com"
Enter fullscreen mode Exit fullscreen mode

To confirm config:

git config --list
Enter fullscreen mode Exit fullscreen mode

5. Stage and Commit Your Changes

Add all files:

git add .
Enter fullscreen mode Exit fullscreen mode

Commit them:

git commit -m "Initial commit"
Enter fullscreen mode Exit fullscreen mode

6. Create a GitHub Repository Using GitHub CLI

Use gh (GitHub CLI) to create a new repo:

gh repo create your-repo-name --public --source=. --push
Enter fullscreen mode Exit fullscreen mode

This automatically:

  • Creates the repo on GitHub
  • Connects it to your local repo
  • Pushes your code

If you don’t have the GitHub CLI yet:

brew install gh  # on macOS
choco install gh  # on Windows
Enter fullscreen mode Exit fullscreen mode

7. Create and Switch to a New Branch 

git checkout -b feature/branch-name
Enter fullscreen mode Exit fullscreen mode

Example:

git checkout -b feature/2025/01-basic-dev-setup
Enter fullscreen mode Exit fullscreen mode

This is useful when working on a new feature while keeping the main branch stable.

8. Push Branch to GitHub 

git push -u origin feature/2025/01-basic-dev-setup
Enter fullscreen mode Exit fullscreen mode

This creates a remote branch and links it to your local one.

Summary Commands Cheat Sheet

Task Command
Initialize Git git init
Configure Git git config --local user.name "Your Name"
Add all files git add .
Commit changes git commit -m "message"
Create branch git checkout -b branch-name
