Answer 1

Before doing any work trying to get data OUT, ya gotta get a little data IN. Get into mongo and insert a few records manually. Baby steps can help you diagnose the issue.

Answer 2

can you try this
User.find((err, users) => {
if (err) res.status(500).send(err);
else res.json(users);
});

Answer 3

**App.js**
const express = require('express');
const app = express();
const mongoose = require('mongoose');
const User = require('./models/users');
const options = {
useNewUrlParser: true,
useCreateIndex: true
};
mongoose.connect('mongodb://localhost/chatter_dev', options)
.then(connected => console.log(`Database connection establised`))
.catch(err => console.error(err));
app.get('/api/users', (req, res, next) => {
User.find().then(user => res.send(user)).catch(err => console.error(err));
})
app.listen(3000);
**Users.js (model)**
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const userSchema = new Schema({
username:{
type:String,
unique:true,
required:true
},
email:{
type:String
},
firstname:String,
lastname:String
}, {timestamps: true});
module.exports = mongoose.model('User', userSchema);
