Executei a seguinte query no mysql e resolveu o problema de conexão:

usuario = colocar o nome do usuário do banco senha= colocar a senha do usuário informado

ALTER USER 'usuario'@'localhost' IDENTIFIED WITH mysql_native_password BY 'senha';

Estou com o mesmo problema porque estou usando o docker do mysql e ele tem um problema com o AllowPublicKeyRetrieval que precisa ser True(para quem usa dBeaver aí por exemplo)....

Consegui resolver da seguinte forma :

no terminal, instale o módulo mysql2 utilizando o npm install mysql2

Toquei o require da seguinte forma :

const mysql = require('mysql') por const mysql = require('mysql2')

Esperto ter ajudado...

Abs,
