Add Gorilla Mux HTTP Router Package Challenge Series

Issue Description

Create a comprehensive Gorilla Mux package challenge series to teach developers powerful HTTP routing in Go, covering everything from basic routing to advanced patterns used in production REST APIs and web services.

What needs to be implemented

Package Structure

Create packages/gorilla-mux/ with the following challenges:

1. Challenge 1: Basic Routing & Path Variables (Beginner)

   • Setting up Mux router
   • Route patterns and path variables
   • Query parameters and form handling
   • Build a simple REST API for a bookstore

2. Challenge 2: Advanced Routing & Middleware (Intermediate)

   • Route constraints and matchers
   • Subrouters and route grouping
   • Custom middleware chains
   • CORS and authentication middleware

3. Challenge 3: REST API Patterns & Validation (Intermediate)

   • RESTful resource routing
   • Content negotiation (JSON, XML)
   • Request validation and error handling
   • Build a complete blog API with CRUD operations

4. Challenge 4: Production Features & Testing (Advanced)

   • Route testing and HTTP testing
   • Rate limiting and throttling
   • API versioning strategies
   • Graceful shutdown and health checks

Required Files for Each Challenge

• README.md - Challenge description and requirements
• solution-template.go - Starting code template with TODOs
• solution-template_test.go - Comprehensive test suite
• learning.md - Educational content (400+ lines)
• hints.md - Step-by-step guidance
• metadata.json - Challenge metadata
• go.mod and go.sum - Dependencies
• run_tests.sh - Testing script

Learning Objectives

• Master HTTP routing with Gorilla Mux
• Learn advanced routing patterns and constraints
• Implement middleware chains and authentication
• Build production-ready REST APIs
• Understand API design best practices
• Practice comprehensive HTTP testing

Resources

• Gorilla Mux Documentation
• REST API Design Best Practices
• Existing package challenges for reference

Acceptance Criteria

• All 4 challenges implemented with complete file structure
• Each challenge demonstrates different routing patterns
• Comprehensive HTTP tests covering all endpoints
• Learning materials explain REST API best practices
• Code follows existing repository patterns and style
• Examples of middleware implementation and testing
• Documentation covers production deployment considerations

Getting Started

1. Study existing package challenges structure
2. Review Gorilla Mux documentation and examples
3. Set up sample REST API for testing
4. Follow the package challenge guidelines from CONTRIBUTING.md
5. Start with basic routing and progress to advanced patterns

Hi there! Thanks for this really detailed challenge; I would love to be added and contribute to this once Hacktoberfest officially begins! In the meantime, I'll be brainstorming :)

@RezaSi Can you please assign me on this? Instead of 1 big PR for the whole issue I'll work on 1 PR for each of 4 challenges?

[saanvi-kataria77]

@RezaSi Please assign me to this as well!

[kaushalyap]

@saanvi-kataria77 You can work on it, I thought you were not interested since your comment was a week ago and no PRs linked.
