asynchronous I/O and cross-platform run-time environment.Those facilities are helpful for building highly scalable server-side applications which use JavaScript. 
Web applications, command-line applications, REST API servers, real-time chat applications can be build using node.js

Advantages And Disadvantages Of Node JS?

Advantages

Single Programming Language Is Enough: node.js can be used for back and front end.
Faster : Using JavaScript in the back end and using google V8 engine makes node.js works faster.
Benefits Of NPM:  Node Package Manager or the NPM has stand-alone tools that allow to users to download and use.So the developer can manage the dependencies by his\her self.
Single-Threaded: To handle multiple concurrent clients, the tool offers many options such as callbacks and event loops.

Disadvantages

Unstable API
Not Good Enough For Heavy Computations

  first, make sure the YourController.java file that has the @Controller and the YourSpringBootFile.java file that has the @SpringBootApplication are in the same package. If you want your controller to be in a different package outside of YourSpringBootFile.java's package, then follow these instructions =  Spring: Run multiple "SpringApplication.Run()" in application main method There are 2 methods to overcome this Place the bootup application at the start of the package structure and rest all controllers inside it. Example : package com.spring.boot.app; - You bootup application(i.e. Main Method -SpringApplication.run(App.class, args);) You Rest Controller in with the same package structure Example: package com.spring.boot.app.rest; Explicitly define the Controller in the Bootup package. Method 1 is more cleaner. referred to:  https://stackoverflow.com/questions/31318107/spring-boot-cannot-access-rest-controller-on-localhost-404 https://stackoverflow.com/questions/3413520...
