mongodb-arbiter-discovery

Poor man's auto-discovery of a mongodb replicaset using an arbiter.

npm install mongodb-arbiter-discovery

Usage

Point at arbiter and get a list of hosts in the replicaset.

var mongoArbiterDiscover = require('mongodb-arbiter-discovery');
mongoArbiterDiscover({
  host: '127.0.0.1',        // Arbiter host name [required]
  port: 27017,              // Arbiter port [default 27017]
  replicaSet: 'rs',         // Replica set name (useful for validation) [optional]
  username: '',             // Username for authentication [optional]
  password: '',             // Password for authentication [optional],
  authOptions: null,        // Passed to `db.authenticate` [optional]
  mongo: require('mongodb') // BYOB mongo library [optional]
}, function(err, hosts) {
  // Host -> ['127.0.0.1:27017', '127.0.0.1:27018', '127.0.0.1:27019']
  // Profit!
});
