Git and GitHub Notes

Introduction

What is Git?

  • Git is a distributed version control system used to track changes in source code.
  • It allows multiple developers to collaborate on a project efficiently.
  • Supports branching, merging, and version history.

What is GitHub?

  • GitHub is a web-based platform that hosts Git repositories.
  • It provides tools for collaboration, such as:
  • Pull Requests
  • Issues
  • Project boards
  • GitHub Actions (CI/CD)

Git Workflow Basics

Initial Setup

git config --global user.name "Your Name"
git config --global user.email "you@example.com"

Starting a Repository

git init                   # Initialize a new Git repo
git clone <repo-url>       # Clone an existing repo

Staging and Committing Changes

git status                 # View current changes
git add <file>             # Stage a file
git add .                  # Stage all changes
git commit -m "message"    # Commit staged changes

Checking History

git log                    # View commit history
git log --oneline          # Compact view
git diff                   # Show changes

Branching and Merging

Working with Branches

git branch                 # List branches
git branch <name>          # Create a branch
git checkout <name>        # Switch to a branch
git checkout -b <name>     # Create and switch

Merging Branches

git merge <branch>         # Merge into current branch
git branch -d <branch>     # Delete branch

Remote Repositories

Adding and Pushing to Remote

git remote add origin <url>   # Link to remote repo
git push -u origin main       # Push changes

Pulling and Fetching

git pull                      # Fetch and merge from remote
git fetch                     # Fetch from remote

GitHub Essentials

Cloning a Repo

git clone https://github.com/user/repo.git

Creating a Pull Request (PR)

  1. Fork the repository
  2. Clone your fork
  3. Create a new branch
  4. Commit and push changes
  5. Open a PR on GitHub

GitHub Features

  • Issues: Report bugs, suggest features
  • Actions: Automate workflows
  • Wiki: Share documentation
  • Projects: Organize tasks with kanban boards

.gitignore

Used to exclude files/folders from version control: 

node_modules/
.env
*.log
.DS_Store
