Depending on which IDE you're using SonarLint is a good option.

Spring Cloud Config could be a good fit.

If you're using Spring I'd recommend taking a look at Spring Security. You should be able to quickly plugin authentication/authorization workflows.

It seems like what you're asking isn't baked into Java. HowToDoInJava see section " What happens when more than one thread is waiting for notification? Which threads actually get the notification when the notify() method is called?" One solution might be to implement a thread scheduler.

The guides are a good start: https://spring.io/guides Baeldung also has good guides: http://www.baeldung.com/ The documentation per project is also good, if you need to go into a lot of detail. If you want to get started quickly with spring I would suggest Spring Boot: https://projects.spring.io/spring-boot/ It provides an opinionated, configured starting point for most projects. Also start.spring.io as a place to generate Spring projects with all the dependencies you may need.

Does your team have access to Artifactory or Nexus? Both have the capability to host an npm repository you could publish your libraries to.

Yes although I have less experience with node.js testing, there is nothing about Jest that wouldn't allow you to test any .js. Enzyme is strictly for testing rendering components, so it wouldn't be necessary.

https://facebook.github.io/jest/ Jest is a good place to start. http://airbnb.io/enzyme/ Jest + Enzyme is what I would recommend. The Jest documentation will take you through examples using Jest + Enzyme.
