Task 1.1: Project Setup and Module Configuration

Summary

Initialize proper Go module structure with buylater.email domain and verify basic project setup.

Motivation

Following Let’s Go Chapter 2.1, we need to establish a solid foundation with proper Go module configuration and a working basic web server. This sets up the project structure for all future development.

Acceptance Criteria

• Go module initialized with github.com/bryfry/buylater module path
• Basic main.go file creates and runs a simple “Hello World” web server
• Server starts successfully on port 4000
• go run . command works without errors

Technical Requirements

Implementation Details

• Use go mod init github.com/bryfry/buylater for module initialization
• Create minimal main.go with HTTP server listening on :4000
• Include basic logging to show server startup

Dependencies

• Go 1.24.2 installed and working
• Project directory structure created

Testing Strategy

Unit Tests

• Verify go.mod contains correct module path and Go version

Integration Tests

• Server starts without compilation errors

Manual Testing

• Run go run . and verify server starts with log message
• Visit http://localhost:4000 and see “Hello World” response

Definition of Done

• All acceptance criteria met
• All specified tests pass
• Code follows project conventions (go fmt, go vet)
• No new console errors or warnings
• Relevant documentation updated
• Human verification completed successfully

Implementation Notes

Approach

Start with the simplest possible HTTP server that demonstrates all three core components (handler, router, server) working together.

Key Files to Modify

• go.mod - Initialize with correct module path
• main.go - Create basic HTTP server structure

Potential Risks

• Module path conflicts if not unique
• Port 4000 already in use during testing

Success Metrics

Server responds to HTTP requests on localhost:4000 with “Hello World” message and proper HTTP status codes.

Related Tasks

• Blocks: Task 1.2 (depends on basic project structure)
• Blocked by: None (first task)
• Related: All subsequent tasks depend on this foundation

Implementation Log

2025-07-20 - Implementation Complete

• Verified go.mod has correct module path: github.com/bryfry/buylater
• Updated main.go to simple “Hello World” HTTP server on port 4000
• Removed extra routes to focus on basic setup per task requirements
• Added proper logging for server startup
• Verified code formatting with go fmt and go vet
• Build successful with go build
