This project guides you through building a web application as a team using professional Git and GitHub workflows. You will experience the complete software development lifecycle — from repository setup through feature development, code review, conflict resolution, and deployment. By the end, you will have hands-on experience with the same collaboration patterns used at companies like Google, Meta, and Amazon.

Project Overview

You will build a simple task management application (similar to a basic Trello board) working in a team of 3-4 developers. Each person is responsible for a different feature, but everyone works in the same repository simultaneously. The goal is not just building the app — it is practicing the collaboration workflow.

Repository Setup

One team member creates the repository and sets up the foundation:

Example

# Create the repository gh repo create team-task-app --public --clone cd team-task-app # Initialize the project npm init -y npm install express # Create initial structure mkdir -p src/{routes,models,views} public/{css,js} tests # Create basic files cat > src/app.js << 'EOF' const express = require('express'); const app = express(); app.use(express.static('public')); app.use(express.json()); app.get('/', (req, res) => res.sendFile('index.html', {root: 'public'})); module.exports = app; EOF # Initial commit git add . git commit -m "Initial project setup with Express" git push origin main

Configuring Branch Protection

Before the team starts, configure protection rules:

Go to Settings → Branches → Add rule for main
Enable: Require pull request reviews (at least 1)
Enable: Require status checks to pass
Enable: Require branches to be up-to-date

Team Roles and Feature Branches

Assign features to team members:

Developer A — Task Board UI:

bash example

git checkout -b feature/task-board-ui
# Build the HTML/CSS for the Kanban board interface

Developer B — Task API:

bash example

git checkout -b feature/task-api
# Build REST endpoints: GET/POST/PUT/DELETE tasks

Developer C — User Authentication:

bash example

git checkout -b feature/user-auth
# Build login/register functionality

Developer D — Drag and Drop:

bash example

git checkout -b feature/drag-drop
# Implement drag-and-drop task movement between columns

The Development Workflow

Each developer follows this cycle:

bash example

# 1. Start fresh from main
git checkout main
git pull origin main
git checkout -b feature/my-feature

# 2. Work in small commits
git add .
git commit -m "Add task card component with title and description"

git add .
git commit -m "Add task creation form with validation"

# 3. Push and open PR
git push -u origin feature/my-feature
gh pr create --title "Add task board UI" --body "Implements the Kanban board layout with three columns"

# 4. Address review feedback
# Make changes based on reviewer comments
git add .
git commit -m "Address review: improve mobile responsiveness"
git push

# 5. Keep branch updated
git fetch origin
git rebase origin/main
git push --force-with-lease

Code Review Practice

When reviewing a teammate's PR:

Pull their branch locally and test:

bash example

git fetch origin
git checkout origin/feature/task-api
npm test
npm start  # Manual testing

Leave meaningful review comments on GitHub:

Logic issues, not just style nitpicks
Suggest improvements with code examples
Approve when satisfied or request changes with clear reasoning

Handling Merge Conflicts

When Developer A and Developer C both modify public/index.html:

bash example

# Developer C tries to merge main (which now has Developer A's changes)
git checkout feature/user-auth
git merge main

# CONFLICT in public/index.html
# Resolve by combining both developers' additions
# Test that both features work together
git add public/index.html
git commit -m "Merge main, integrate auth UI with task board"

Adding CI/CD with GitHub Actions

Create .github/workflows/ci.yml:

Example

name: CI on: [push, pull_request] jobs: test: runs-on: ubuntu-latest steps: - uses: actions/checkout@v4 - uses: actions/setup-node@v4 with: node-version: '20' - run: npm ci - run: npm test - run: npm run lint

Project Milestones

Create GitHub milestones to track progress:

Sprint 1: Basic UI and API (week 1)
Sprint 2: Authentication and drag-drop (week 2)
Sprint 3: Integration, testing, deployment (week 3)

Deployment

After all features are merged and tested:

bash example

# Tag the release
git tag v1.0.0
git push origin v1.0.0

# Deploy (e.g., to Render or Railway)
# The CI/CD pipeline handles deployment automatically on tag push

Learning Outcomes

By completing this project, you will have practiced:

Creating and managing feature branches
Writing descriptive pull requests
Conducting code reviews
Resolving merge conflicts
Using GitHub Issues and milestones
Setting up CI/CD pipelines
Collaborating asynchronously with team members

Key Takeaways

This project simulates a real professional development environment. The technical complexity is intentionally moderate — the focus is on mastering the collaboration workflow. These patterns scale directly to industry work where you will manage far more complex features using exactly these same Git and GitHub practices. The skills you build here — branching, reviewing, communicating through PRs — are what make you an effective team member from day one at any company.

Exam Focus

Revise definitions, diagrams, examples, and short-answer points for Collaborative Web App Project.

Interview Use

Prepare one clear explanation, one practical example, and one common mistake for this Git & GitHub topic.
