Is there an easy way to read tls certificate and key from a filesystem?

if (Deno.env.has("TLS_CERT_PATH") && Deno.env.has("TLS_PKEY_PATH")) {
  const tlsCert = Deno.readFileSync(Deno.env.get("TLS_CERT_PATH"));
  const tlsPkey = Deno.readFileSync(Deno.env.get("TLS_PKEY_PATH"));
  serverOptions = { cert: tlsCert, key: tlsPkey };
}

if (Deno.env.has("TLS_CERT_PATH") && Deno.env.has("TLS_PKEY_PATH")) {
  const tlsCert = Deno.readFileSync(Deno.env.get("TLS_CERT_PATH"));
  const tlsPkey = Deno.readFileSync(Deno.env.get("TLS_PKEY_PATH"));
  serverOptions = { cert: tlsCert, key: tlsPkey };
}
