MongoDB - Error: invalid schema, expected mongodb

Question

I\'m new in building application with MEAN Stack, I\'m trying to build a real time chat app, here is my server side :

console.log(\"Server running...!\");

v         


        

Answer 1

This is because you are using the connection string in an improper format.

You are using localhost:27017/db/chat while it should be mongodb://localhost:27017/db/chat

The pattern for the connection string is mongodb://:/
