I looked at this popular question, but it didn't seem to fix my issue, so I'm going to post this.

I currently have an express.js server file using mongoose, that keeps returning an empty array. I have no idea if it might by an async issue, and I don't know what I can use to indicate that I'm connected to my database.

const express = require('express');
const app = express();
const bodyParser = require('body-parser');
const mongoose = require('mongoose');
const PORT = process.env.PORT || 8080;


//Mongoose stuff
mongoose.connect('mongodb+srv://excelsiorAdmin:Mysecretpassword@excelsiorcluster-zakfd.mongodb.net/test?retryWrites=true', useNewUrlParser: true, dbName: 'excelsiorDB');
const dbConnection = mongoose.connection;

dbConnection.on('error', console.error.bind(console, 'connection error:'));
dbConnection.once('open', function() 
 console.log('connected to the database');

 let charSchema = new mongoose.Schema(
 imageURL: String,
 company: String,
 name: String,
 civName: String,
 alignment: String,
 firstDebut: String,
 abilities: Array,
 teams: Array,
 desc: String
 );

 let Char = mongoose.model('Char', charSchema, 'chars');

 //root
 app.get('/', (req, res, next) => res.send('Welcome to the API!'));

 //get all characters
 app.get('/chars', (req, res, next) => 
 console.log('getting all characters');
 Char.find(function (err, chars) 
 if (err) 
 res.status(404).send(err);
 console.log('there was an error');
 ;
 console.log(chars);
 res.send(chars);
 );
 );

 //get heroes
 app.get('/chars/heroes', (req, res, next) => 
 Char.find(alignment: "Hero", function (err, chars) 
 if (err) 
 res.status(404).send(err);
 ;
 res.send(chars);
 );
 );

);

app.listen(PORT, () => console.log(`This API is listening on port $PORT!`));

The mongoose.model will set the collection it's looking for equal to the lowercase, pluralized form of the name of the model.

let Char = mongoose.model('Char', charSchema);

This will look for the "chars" collection. However, if the database you're connecting to doesn't have a collection with the same name as the mongoose default, it will return results from a collection that doesn't exist. To make sure it hits the right collection if they don't match, you'll have to manually enter the collection's name as a third parameter:

let Char = mongoose.model('Char', charSchema, "excelsiorCollection");
