Introduction
Building real-world applications in the JavaScript language requires dynamic programming, where the size of the JavaScript application grows uncontrollably. New features and updates get released, and you need to fix bugs to maintain the code.
To execute this, new developers need to be added to the project, which becomes complicated. The structure of modules and packages is unable to downsize and simplify the application. To run the application smoothly, it is essential to convert the large, homogeneous structure into small, independent pieces of programs. Such complexities can be resolved effortlessly when JavaScript applications are built on microservices, more so with the Node.js ecosystem.
