Dev.to Stylesheet Utility

This project provides a utility to periodically fetch stylesheets from dev.to and make them available for use in your own projects.

A cron job that:

• Periodically fetches the dev.to homepage
• Extracts the stylesheet links using regex
• Stores the extracted links in blob storage
• Keeps track of changes and maintains a version history
• Sends email notifications when changes are detected

An HTTP endpoint that:

• Serves the latest stylesheet links in various formats
• Provides JavaScript and CSS embed options
• Offers an API to access current and historical stylesheet data
• Includes documentation and usage examples

1. Set up the Stylesheet Fetcher:

   • Set the cron trigger on devto-stylesheet-fetcher.ts to run at your desired interval (e.g., daily)
   • The first run will fetch the initial stylesheets

2. Set up the Stylesheet Provider:

   • Set the HTTP trigger on devto-stylesheet-provider.ts
   • Access the root URL for documentation and usage examples

There are several ways to use the dev.to stylesheets in your project:

<script src="https://your-val-town-url.val.run/embed.js"></script>

This will dynamically load all the dev.to stylesheets into your page.

<link rel="stylesheet" href="https://your-val-town-url.val.run/embed.css">

This loads a CSS file that imports all the dev.to stylesheets.

Fetch the stylesheets programmatically:

fetch("https://your-val-town-url.val.run/api/stylesheets")
  .then(res => res.json())
  .then(data => {
    // Use the stylesheet URLs as needed
    console.log(data.stylesheets);
  });

• GET / - Documentation and status page
• GET /api/stylesheets - Get the current stylesheets as JSON
• GET /api/history - Get the history of stylesheet changes
• GET /embed.js - JavaScript snippet to load the stylesheets
• GET /embed.css - CSS file that imports all the stylesheets

The utility uses Val Town's blob storage with the following keys:

• devto_stylesheets - Current stylesheet data
• devto_stylesheets_last_updated - Timestamp of last update
• devto_stylesheets_history - History of stylesheet changes

• The utility relies on the current structure of dev.to's HTML. If dev.to changes their HTML structure, the regex extraction may need to be updated.
• The utility only extracts stylesheet links and does not handle inline styles or dynamically loaded stylesheets.
• Dev.to may have usage restrictions or rate limits that could affect the fetcher.

• Add support for selective stylesheet inclusion
• Implement stylesheet minification and combination
• Add support for custom CSS overrides
• Implement more robust error handling and retry logic
