Task 1.3: Multiple Route Implementation

Summary

Implement multiple routes specifically for the buylater.email service user flow with proper routing patterns and 404 handling.

Motivation

Following Let’s Go Chapter 2.3, we need to implement the core user-facing routes that will support the buylater.email service. This establishes the URL structure for the complete email reminder workflow: submission, confirmation, and management.

Acceptance Criteria

• Home route GET /{$} displays buylater.email landing page
• Submit route GET /submit shows email submission form placeholder
• Confirm route GET /confirm shows email confirmation page placeholder
• About route GET /about shows about page placeholder
• 404 responses for undefined routes work correctly
• Each route returns unique content clearly identifying its role in the buylater.email workflow

Technical Requirements

Implementation Details

• Use {$} syntax for exact home route matching
• Create separate handler functions for each buylater.email route
• Implement proper 404 handling for undefined routes
• Return simple HTML content that clearly identifies each page’s role in the email reminder workflow

Dependencies

• Task 1.2 completed (basic web application structure)

Testing Strategy

Unit Tests

• Each handler function returns expected content
• Route registration works correctly

Integration Tests

• Router correctly maps URLs to appropriate handlers

Manual Testing

• Each route returns unique content identifying its buylater.email purpose
• Undefined routes return 404 status
• All routes accessible via browser navigation
• Home page accessible at both / and exact root
• Route content clearly explains the buylater.email service workflow

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
• Git commit created with proper message format

Implementation Notes

Approach

Create the basic URL structure that matches the buylater.email user flow: landing page → email submission → confirmation → about. This establishes the foundation for the delayed gratification email service.

Key Files to Modify

• main.go - Add multiple route handlers and registrations

Potential Risks

• Route conflicts or overlapping patterns
• Incorrect use of exact vs subtree matching

Success Metrics

All core buylater.email user paths are accessible via clean URLs that support the delayed gratification email reminder workflow.

Related Tasks

• Blocks: Task 1.4 (wildcard routes build on basic routing)
• Blocked by: Task 1.2 (needs proper router setup)
• Related: Task 1.5 (method-based routing extends these routes)

Implementation Log

2025-07-20 - Implementation Complete

• Added four buylater.email-specific route handlers: home, submit, confirm, about
• Updated home route to use exact matching with /{$} syntax
• Created clear, descriptive content for each route explaining its role in the email reminder workflow
• All routes now reflect the buylater.email service purpose rather than generic tutorial content
• Verified code formatting with go fmt and go vet
• Build successful with go build
• 404 handling works automatically for undefined routes
