Ok, I lie, this demo is also pretty simple, but I wanted to break the pattern of the last few posts and at least pretend this example is a bit more complex. As I try to find excuses to write more TypeScript, I thought a great example of that would be a simple RSS aggregator. You hit the site, tell it the feeds you care about, and it renders a date sorted list of entries. Because RSS typically can't be parsed in client-side JavaScript (don't know why? ask me below!) so I'd have to make use of a serverless function...
