The Connection Between Node.Js And Microservices

Node JS is an open-source, cross-platform runtime environment that allows you to build fast, and efficient network applications.

It offers various security, development, editing and debugging features that make it the best web development company. The website development services provided by Node JS allows the developer to deploy the application directly.

This eliminates the need for deploying the application to a stand-alone server first. Node.js also provides a rich library of various JavaScript modules which simplifies the development of web applications using Node.js to a great extent. The website development services provided by Node JS have various features like fast access to the library.


Node JS is built on google chrome’s V8 JavaScript engine and therefore is very fast in code execution. Node Js uses single-threaded architecture with loops. This kind of architecture handles traffic more efficiently. Node JS uses a single-threaded program and the same program can provide service to a much larger number of requests than traditional servers.

In addition to this, Node Js never buffers data. It just provides the data in chunks. So there’s no waiting. There dynamic features of Node Js make it the best choice for software engineers and make it the best web development company.


Microservices are a solution to the scalability and innovation challenges with Monolith architectures. Building a huge application making multiple tasks complex coding and architecture to make it efficient. Sometimes it becomes difficult to understand complex code ends up in an incomplete task.

Such complex codes and architecture require regular testing to ensure the application works properly after the changes. And even if you want to make a small change in the program, the whole applications need to be built and deployed. Everyone might have experienced the dread of waiting for a heavy application to open. Because there are so much coding and data stored in the application, it slows down the application. This is why microservices were adopted.

It is a solution to this huge complex architecture to work efficiently as small bits. In microservices, the application is broken into smaller modules which are easy for the programmers to develop and maintain. The adaptation of technology building services from traditional methods to microservices is easy.


By using microservices, process adaptation is made easier. Microservices also have an independent scaling. Large applications remain largely unaffected by the failure of a single module.

A small failure doesn’t disrupt the whole application and can the problem can be addressed and solved independently. Each service- deployed, updated, replaced and scared can be dealt with independently. So, microservices can be visualized as a self-contained unit, which together with other units, makes up large applications.

The Connection between the two

The merging of these two softwares is very practical and efficient. JavaScript applications are rather long and complex. As the JavaScript application starts to grow in size, you start to face challenges with fixing the bugs, maintaining and understanding the complex codes, finding errors and implementing new features. This handling of a large amount of data becomes a challenging task without resources. And adding new developers to the projects just makes it complicated.

By introducing the concept of microsystems, the application can be built from pieces and modules. When large applications and data structures are broken into smaller modules, the complexity decreases. Let’s say there’s a problem with one part of the code which is causing the application to not work. With a large JavaScript architecture, finding the area of problem is very difficult. Even after you’ve found the area of conflict, changing the application requires re-running the application completely. Now if these data structures were broken down into small modules and one module has an error, you can just debug the module and attend to the error without having to affect the entire application. Microservices are those structure which structures an application as a collection of loosely coupled services. Services are fine-grained and the communication protocols are lightweight (like the HTTP protocol). To get these services, you can hire a custom software development company.

Some of the benefits worth mentioning of microservices and Node JS are-

  • Modularity

Responsibility for specific operations is assigned to separate pieces of the application so each one can be dealt with independently. Each piece executes the action assigned to it so that there is no traffic.

  • Uniformity

Microservices interfaces (API endpoints) consist of a base URI identifying a data object and standard HTTP methods (GET, POST, PUT, PATCH and DELETE) used to manipulate the object

  • Robustness

Component failures cause only the absence or reduction of a specific unit of functionality. Failure of a single module doesn’t affect the complete application. Which makes the application very efficient. It also makes the process of debugging easy.

  • Maintainability

System components can be modified and deployed independently. This was mentioned as the architecture of microservices. Maintaining smaller modules is easier than maintain a set of complex codes altogether.

  • Scalability

Instances of service can be added or removed to respond to changes in demand. This can be done independently without affecting the application. Microservices provides custom application development services.

  • Availability

New features can be added to the system while maintaining 100% availability. The custom application development services provided by microservices allow you to keep updating your application as per your need and demand.

  • Testability

New solutions can be tested directly in the “battlefield of production” by implementing them for restricted segments of users to see how they behave in real life.


The most significant feature that microservices allow is that every microservice can be written using the language, technique, and framework that’s most suitable for the tasks to perform. The only feature that is necessary is the ability to publish restful APIs for other communication services. An offshore IT Services provider can be hired to do so.

There is a number of websites built using microservices model; Amazon is the best example to take into consideration. At Amazon, the DevOps team is responsible for maintaining and building services to run the website with the help of 200 or more services.
