What is the best way to learn practical Node.js?
I want to be a Node.js developer.
All the courses I found on the Internet (paid or unpaid) seems to have little to very basic knowledge of Node.
These courses are unable to full fill my thirst for knowledge.
Kindly recommend me a good source to learn Node.js.
Yes I am asking for your Opinion.

Read the documentation and learn the best practices. Once you learn to control the flow, you can do anything with it. My suggestion would be to find a problem statement and try to solve that using Node.

I am just about to make a small instant messaging server.
I am thinking of using MongoDB, NodeJS, and Redis. Do you think it is a good choice?
What do you think about the model schema?
It's really a good choice. If I were you, I'd use socket.io, node.js, and mongoDB.
you can also use mongoose which is a model-based and It's much better.
MongoDB(Mongoose) is a good choice, because when you do a instant messaging application, it's a good choice (you will need ) to store data as documents.

I see that sonarQube can be used for measuring code quality and for finding security vulnerabilities. I am having hard time deciding whether to replace the custom-build BDD security testing scenarios with sonarQube testing for my backend services. BDD testing usually takes longer than the sonarQube analysis. I would appreciate your suggestions on this.
Thanks
These two things are complementary. I wouldn't stop either in favor of the other.

We are starting out a new Nodejs project, and I am working on wiring up Winston to Loggly.
Since we are new to node, my question is, what is typically information that should be logged and in what format for Loggly to accept it? What do you guys find helpful when going through the logs, i.e, remote address, method where error happend, etc... ?
This Ultimate Guide to Logging in Node give some some good ideas you can use as a starting point. It also gives you tips on how to troubleshoot common problems. I helped put the team together to write it. It's an open source guide, and we take suggestions on topics and content from the community.

Am trying to get Facebook and google login functionality integrated in my node.js app.
I have heard of passport library but has never used it. Can anybody help me,whether to use this library or write the code without it?

if suggesting passport library,kindly share its pros and cons.
TIA.
Everything is basically already done for you with Passport. I would say that and the fact that it has a huge community behind it is it's biggest advantages. If you need an example how to do it (and how easy it is) I recommend from this article on scotch.io
