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.
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.
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")],
},
});
