I have server.js and db.js The db.js file interacts with my database using Mongoose and I use server.js to call functions from db.js :
var mongoose = require('mongoose');
mongoose.connect('', { useNewUrlParser: true })
var Schema = mongoose.Schema;
module.exports = function () {
var db = mongoose.connection;
db.on('error', console.error.bind(console, 'connection error:'));
return db.once('open', function() {
console.log("Connected to DB")
var postschema = new Schema({
title: String,
intro: String,
body: String,
author: String,
timestamp: { type: Date, default: Date.now }
});
var post = mongoose.model('post', postschema);
return {
newPost(title, intro, body, author) {
var newpost = new post({
title: title,
intro: intro,
body: body,
author: author
})
},
getPostsAll() {
post.find({}, function (err, res) {
return (`Error:${err} Posts:${res}`)
})
}
}
})
}
And my server.js calls three functions from db.js :
var DB = require('./db.js')
var db = DB()
db.getPostsAll()
db.newPost()
I don't understand why I get this error :
connection error: { MongoNetworkError: connection 4 to black-test-shard-00-01-ewyaf.mongodb.net:27017 closed

What am I doing wrong? I found an article but can't make anything of it.
