My credentials work perfectly with Robomongo but I can\'t make the connection with node.js

Answer 1

You can do it with official mongodb client for node

const sshTunnelConfig = {
  agent: process.env.SSH_AUTH_SOCK,
  username: 'ec2-user',
  privateKey: require('fs').readFileSync('./path-to-ec2-key.pem'),
  host: '3.98.174.12', //IP adress of VPS which is the SSH server
  port: 22,
  dstHost: 'docdb-cluster-vmabwxueb51y.eu-central-1.docdb.amazonaws.com',
  dstPort: 27017,
  localHost: '127.0.0.1',
  localPort: 27018 //or anything else unused you want
};


const connectionProperties = {
  sslValidate: true,
  ssl: true,
  sslCA: [fs.readFileSync('rds-combined-ca-bundle.pem')],
  useNewUrlParser: true,
  useUnifiedTopology: true,
  authMechanism: 'SCRAM-SHA-1',
  auth: {
    user: 'docdbuser',
    password: ''
  },
  tlsAllowInvalidHostnames: true,
  tlsAllowInvalidCertificates: true,
};

tunnel(sshTunnelConfig, async (error, server) => {
  if (error) {
    console.log('SSH connection error: ', error);
  }
  
   const MongoClient = require('mongodb').MongoClient;
   const client = MongoClient.connect('mongodb://localhost:27018/', propertiesConnection,
    function(err, client) {
      if(err)
        throw err;

      //Specify the database to be used
      db = client.db('database-name');

      //Specify the collection to be used
      col = db.collection('collection-name');

      //Insert a single document
      col.insertOne({'hello':'Amazon DocumentDB'}, function(err, result){
        //Find the document that was previously written
        col.findOne({'hello':'Amazon DocumentDB'}, function(err, result){
          //Print the result to the screen
          console.log(result);

          //Close the connection
          client.close()
        });
      });
    });
  
});
