According to the Mongoose docs you can connect to a MongoDB with a default port of 27017.
mongod output ends with:
I NETWORK [initandlisten] waiting for connections on port 27017
But when I try and connect to my database like this:
const mongoose = require('mongoose'); mongoose.connect('mongodb://localhost/myapp');
Unhandled rejection MongoError: port must be specified
What is happening here?
I have Mongoose v5.2.0, node v9.10.0, and MongoDB shell version v4.0.0.
If I change my connection string to include the port
mongodb://localhost:27017/myapp then I am able to connect. But I'm not sure why I need this.
Port should also be specified in mongoose.connect() in the latest version of mongoose (5.2.0):
27017 is MongoDB's default port on which mongod is running.
Another solution is to revert to mongoose 5.1.7 which won't cause this issue:
npm install email@example.com --save
Let me know if that fixes it.
