How to make MongoClient (mongodb package from node.js) try to connect to database again?

Question

MongoDB

var http = require('http')
  , mongodb = require('mongodb');

var options = {
    {
        uri_decode_auth: true,
        numberOfRetries: 1000,
        db: {
            numberOfRetries: 1000,
            retryMiliSeconds: 5000,
            bufferMaxEntries: 0
        },
        server: {
            auto_reconnect: true,
            socketOptions: {
                connectTimeoutMS: 5000,
            },
            reconnectTries: 1000,
            reconnectInterval: 5000,
        }
};

mongodb.MongoClient.connect('mongodb://username:[email protected]:27017/dbname', options, function(err, db) {
    if (err) {
        console.log('failure');
        return;
    }
    console.log('success');
    http.createServer(function(request, response) {

    }).listen(80);
});

If the database is not running when the script is run, the script prints failure and does nothing else. If you raise the base, then also no reaction. If the database works immediately at startup, then output success and it works correctly.

Answer 1

Well, you yourself indicated

server: {
     auto_reconnect: false,

so it doesn't reconnect.

Answer 2

auto_reconnect: false, maybe you should set it to true first?
