Agree. I am using node_redis module and it has "connected" field and "on error" callback. If disconnect happened - "connected" field set to false and node_redis try to connect repeatedly firing "on error" until the connection established.

Maybe Mongoose should work on the same model.

this might be helpful: https://gist.github.com/1058819

The native mongodb driver has an auto reconnect feature, but Mongoose doesn't provide the option to pass the flag that turns it on when the connection is established. This is a workaround to enable it:

var mongoose = require('mongoose');
mongoose.connect('mongodb://...');
mongoose.connection.db.serverConfig.connection.autoReconnect = true

@rpbertp13, that's much nicer than my solution thanks!

@rpbertp13 last time I tried that (several months ago), that didn't do anything. perhaps it's working now.

Works for me with the current version (0.9.6.1). The code is definitely there: https://github.com/LearnBoost/mongoose/blob/master/support/node-mongodb-native/lib/mongodb/connection.js#L233-233

cool. I'll give it a try again but I hink this issue should be left open until the issue is directly addressed by mongoose, at the API level even.

Using 1.5.
dbConnection = mongoose.createConnection(....);
mongoose.connection.db.serverConfig.connection.autoReconnect = true;

throws:
TypeError: Cannot read property 'serverConfig' of undefined"

This syntax worked for me:

dbConnection = mongoose.createConnection(....);
dbConnection.db.serverConfig.options.auto_reconnect = true;

Just merged pull #410 into branch v1.x in this morning. Options can now be passed to Server, ReplSetServer, and Db. The auto_reconnect option is enabled by default.
