how to get mongodb current featureCompatibilityVersion into a variable with only version
I want to create an interface for all running processes in Mongodb
I have three 3 node cluster on-premises ( 1 Primary and 2 Secondary ). I have same 3 node cluster in AZURE ( 1 Primary and 2 Secondary ) with same version and data but with different FQDN in azure. How shall I connect mongodb replica set in azure to mongodb replica set in on-premises so that they can start replicating the data. Later I would like to switch off on-premises mongodb and move finally to azure. My question is:
I am building an application using MongoDB, Angular, Express, and Node (MEAN stack).
I am using Mongodb (Rails 3 + Mongoid) and Angular JS.

I have items in a collection that run through this aggregate to find them with an average rating and to find them when they have not yet been commented on / rated yet.

I am making react project using express.js, mongodb, react.js, and node.js. and trying to fetch data from backend api which is running on port 5000.
I’m writing program that uses React as front-end, and an Express/Node API for the backend which then does CRUD operations in a MongoDB database. Right now, I’m using the native JS fetch() API to perform GET/POST operations on my front end. The GET requests work just fine, but my POST requests seem to not be working.
