Set the tls key to configure TLS. Both key and cert are required. The key should be the contents of your private key; cert should be the contents of your issued certificate. Use Bun.file() to read the contents.
/icons/typescript.svgserver.ts
const server = Bun.serve({
	fetch: request => new Response('Welcome to Bun!'),
	tls: {
		cert: Bun.file('cert.pem'),
		key: Bun.file('key.pem'),
	},
});
By default Bun trusts the default Mozilla-curated list of well-known root CAs. To override this list, pass an array of certificates as ca.
/icons/typescript.svgserver.ts
const server = Bun.serve({
	fetch: request => new Response('Welcome to Bun!'),
	tls: {
		cert: Bun.file('cert.pem'),
		key: Bun.file('key.pem'),
		ca: [Bun.file('ca1.pem'), Bun.file('ca2.pem')],
	},
});
