The official documentation given by MongoDB states about different connection operations. For implementing a keep alive, you need to use the keepAlive option in the connection URI.

// Connection URI
const uri = "mongodb+srv://sample-hostname:27017/?keepAlive=true";

This will enable keepAlive on the TCP socket.

If you want to have a delay before initiating keepAlive on the TCP socket, you can use the keepAliveInitialDelay option in the URI. The keepAliveInitialDelay should be of an integer type.

// Connection URI
const uri = "mongodb+srv://sample-hostname:27017/?keepAlive=true&keepAliveInitialDelay=30000";
