pale-apex-preamble

A replacement for a simple express app that accepts a URL on its / endpoint and returns the page's source code to the requesting browser.

• Added as a test and to replace a similar application formerly hosted at glitch.
• Moved main app away from express and implemented an HTTP Type val.

# Start local development server
./dev.sh local
# or
deno task local-dev

# Deploy to Val Town
./dev.sh push
# or
deno task push

• ./dev.sh dev - Start Val Town development server
• ./dev.sh local - Start local development server (port 3001)
• ./dev.sh push - Format, check, and deploy to Val Town
• ./dev.sh status - Check project status
• ./dev.sh logs - View logs
• ./dev.sh help - Show all commands

Test locally: http://localhost:3001?url=https://example.com

• The / endpoint with no parameters shows a simple HTML form for entering a URL
• When provided with a url query parameter, it returns the source code of that page as plain text
• Includes URL validation and error handling
• Migrated from Express.js to Val Town HTTP handler format

The original Express app was a simple form that accepted a URL and returned the source code. The new implementation:

1. Provides a more user-friendly HTML form when no URL is provided
2. Validates the URL format before attempting to fetch
3. Returns the source as plain text for easy viewing
4. Handles errors gracefully with appropriate status codes

GET /?url=https://example.com

Returns: The source code of the specified URL as plain text
