Common HTTP server usage

const server = Bun.serve({
	async fetch(req) {
		const path = new URL(req.url).pathname;

		// respond with text/html
		if (path === '/') return new Response('Welcome to Bun!');

		// redirect
		if (path === '/abc') return Response.redirect('/source', 301);

		// send back a file (in this case, *this* file)
		if (path === '/source') return new Response(Bun.file(import.meta.path));

		// respond with JSON
		if (path === '/api') return Response.json({some: 'buns', for: 'you'});

		// receive JSON data to a POST request
		if (req.method === 'POST' && path === '/api/post') {
			const data = await req.json();
			console.log('Received JSON:', data);
			return Response.json({success: true, data});
		}

		// receive POST data from a form
		if (req.method === 'POST' && path === '/form') {
			const data = await req.formData();
			console.log(data.get('someField'));
			return new Response('Success');
		}

		// 404s
		return new Response('Page not found', {status: 404});
	},
});

console.log(`Listening on ${server.url}`);
