The file dbConfig need to have a function for mysql.query where a new connection is created and a query function is returned as a promise to be able do use async/await when I get data from the database.
Something like this:
const util = require( 'util' );
const mysql = require( 'mysql' );
function makeDb( config ) {
const connection = mysql.createConnection( config );
return {
query( sql, args ) {
return util.promisify( connection.query )
.call( connection, sql, args );
},
close() {
return util.promisify( connection.end ).call( connection );
}
};
}
