I am also coming from a Java background.

We have everything like Spring and Hibernate to help us in development and having cleaner separation of concerns.  I am sure that such will come to the Node world too; actually it could be there already, I just dont know which or what they are.  It is a relatively young world.
Hi Guys,

Front end:  I think react should be isolated to front end stuff, like getting input, displaying output, making the ui easy to use.  This should not have business logic that are confidential or security-related stuff.

Express:  I really not sure, but this sounds like counter-part of Spring Controllers.  So I am thinking of able to put some logic here, but heavy business logic, especially those related to reusable services like talking to databases, will be isolated in Node modules (simple separated javascript files, maybe 1 javascript file per service, e.g. 1 for LoginService, 1 for CustomerService, etc.).

Node:  simply there to run the Express, and support the javascript modules (which would run on node, and called by Express controllers)

React <--> Express controllers <--> Node services

I have been looking at where to put the business logic, but can see definitive answers in web.  Probably there isnt.  But what are the best practices, and possibly any framework out there to 'force' us to do a better separation of these concerns?  

I will greatly appreciate your sharing of your knowledge.

I'd like to know what the main advantages Go has in relation to other languages.

Thanks & Regards,

In addition to what Cleo asked, what are the limitations of what Go can do, if any? (e.g. java can do only what the jvm exposes)

Typo above.  Should be 'Spring In Action' book.

By the way, I believe there is also an available book or preparation course on Spring 5 certification now.  Try Udemy or amazon.

I want to go for spring core certification but I couldn't find any good reference. I have searched and googled about it and what I came to know is about the book spring in action 4th ed. But I also went on and came to know that many people have used this book for this certification but didn't do well on the exam.

So if anyone knows some good reference for spring core certification that I should use for the exam please tell me.

There is now a 5th edition of Spring 5 In Action, for Spring 5.

Please note that the list of topics in the exam is in Pivotal website.  More than half of the book is not part of the exam.  For deeper, more complete knowledge to prepare for the exam, you can refer to the Spring Reference, on the related topics.

My practice tests are based on the Pivotal list of topics.
They are at (Spring 5, 4.3, 4.2), and (Spring 4.3, 4.2).

Thank you for the reply.

In terms of technology, I heard of Spring Cloud (java-based development) + Travis CI/CD + Docker + AWS, as a good combination.  What do you think?

And also what are the other tech stack options when designing a cloud native system?
