Docker, NodeJS, and MySQL 8

Seen this error when using Docker for NodeJS and MySQL 8?

Error: ER_NOT_SUPPORTED_AUTH_MODE: Client does not support authentication protocol requested by server; consider upgrading MySQL client

It is most likely the wrong package is being used.

• mysql package does not support MySQL 8 authentication method (More info here)
• Use mysql2 package

Note

Make sure the MySQL server is fully running before trying to connect, otherwise an error like below

Error: connect ECONNREFUSED 172.17.0.1:3306
