MySQL pool (via TypeORM): how to detect a possible shutdown of the database server?

Question

MySQL

Good day! I'm trying to figure out TypeORM, and in general, working with MySQL in a node.
TypeORM uses the normal mysql driver under the hood and creates a connection pool. I can't figure out how to detect possible database server disconnects in the future, after the initial connection is established.
At the moment, every second I "ping" the database with the "select 1" request, which returns an error if the database server is down. But I hope that there is a less "crutchy" way for the application to learn about changes in its state.
