I'm developing the backend for a website. The main app uses KeystoneJS to provide an admin UI for those who create content, and Keystone runs on top of MongoDB (specifically mongoose). The content is served to a main website and mobile app, and so to provide a backend API server to these I am writing a separate Express app.
The backend server attempts to access the underlying Mongo database using mongoose. I call mongoose.connect() using the following connection string and options:
var db_connection = 'mongodb://db_user:db_pass@localhost:27017/db';
var db_options = {
autoReconnect: false,
bufferMaxEntries: 0,
poolSize: 10,
};
The connection is successfully opened, as logged by mongoose.connection.on('connected', ...); and I can manually look at the database using the MongoDB shell to confirm that there are documents in the database.
However, when I attempt to query the database, using:
var events = Event.find();
events.exec((err, events) => {
console.log('/api/events: events found, sending to client');
if (err) res.send(err);
res.json(events);
}).catch(err => console.log('error: ' + err));
where Event is keystone.list('Event').model, the query hangs and the exec callback never gets called, since the console log is never printed to the terminal.
I've properly initialized Keystone and imported the models, so I don't believe the issue is with the Keystone model but with mongoose itself. Additionally, if I execute the above code inside the Keystone app, it runs successfully, just not in my backend Express app.
