Web Applications

Building real web applications means understanding how front-ends and back-ends work together. This section covers the essential patterns, technologies, and architectures that power modern web development.

Full-Stack Fundamentals

These guides focus on practical, hands-on web application development. You’ll learn to build complete applications that handle real user interactions and data persistence.

What You’ll Learn

🔌 REST API Development

Learn to design and build APIs that front-end applications love to consume.

REST API Fundamentals →

🏗️ Application Architecture

Understand the three-tier architecture that powers most web applications.

Learning Path

1. Foundation Concepts

Start here to understand how web applications are structured:

Three-Tier Architecture - The blueprint for scalable web apps
REST API Fundamentals - How front-ends and back-ends communicate

2. Backend Development

Learn to build robust server-side applications:

FastAPI Simple User API - Python-based REST API development
Spring Boot Simple User API - Java-based enterprise API patterns

3. Frontend Development

Build modern user interfaces that consume REST APIs, progressing from fundamentals to frameworks:

REST API Fundamentals - Understanding the communication foundation
Vanilla JavaScript + Fetch - Core browser technologies and DOM manipulation
Vue.js Task Manager - Progressive framework with reactive data binding
React Task Manager - Industry standard patterns with hooks and modern React

4. Full-Stack Integration

Put it all together with complete applications:

Simple Messaging App - Real-time communication with SQLAlchemy

Development Approach

These guides emphasize:

Practical Examples: Working code you can run and modify
Real-World Patterns: Techniques used in production applications
Progressive Learning: Each concept builds on the previous ones
Career Relevance: Skills that directly translate to job requirements
