Question

Connecting from Node.js to MySQL managed database

Hi,

We are trying to connect the MySQL managed database cluster from Node.js app, and DB configuration as follows,

export const databaseConfig: DatabaseConfig = {
    username: 'doadmin',
    password: 'xxxxxxxxx',
    database: 'xxxxxxxxx',
    host: 'xx-xx-xx-xxxx-xx-xxx-xxx-x.db.ondigitalocean.com',
    port: 25060,
    dialect: 'mysql',
    logging: true,
    force: true,
    timezone: '+00:00',
    pool: {
        max: 100,
        min: 0,
        idle: 200000,
        acquire: 1000000,
    },
    ssl: true,
    dialectOptions: {
        ssl: {
            ssl: true,
            cert: fs.readFileSync(process.env.INIT_CWD + '/server/config/' + 'glitra_mysql_ca-certificate.crt')
        }
    },

The .crt file is downloaded from DO database connection setting section, When we run the application we are getting “self signed certificate in certificate chain”.

Anybody tried connecting with from Nodejs to managed db and help us on this issue?

Thanks, -SK

Hello,

Looking at the error message it does seem like the issue might be around how the SSL is handled.

In your code if you set SSL mode to false do you still see this issue or add NODE_TLS_REJECT_UNAUTHORIZED=‘0’ as an environment variable

Also as a reference the below URL has similar issue and workaround .
