npm install mysql-sshSets up a MySQL connection inside an SSH tunnel.
This is practical when you want to reach a database which is only accessible through a webserver.
Even if the database server is not located on the webserver itself.

* sshConfig should be an object according to the ssh2 package.
* dbConfig should be an object according to the mysql2 package.
* Returns a Promise, containing a connection from the mysql2 package.
.close() the tunnel connection when you're done querying the database.``javascript
const mysqlssh = require('mysql-ssh');

privateKey: fs.readFileSync(process.env.HOME + '/.ssh/id_rsa')
},
{
host: 'my-db-host.com',
user: 'me-db',

console.log(results);
mysqlssh.close()
