Node.js is the most powerful technology for building an effective web application. It can facilitate the development of many different microservices that contribute towards building a larger application. It has the most flexible architecture that helps to build complex and real-time applications.

Node.js microservices are suitable for:

  • real-time collaboration tools
  •  streaming and networking apps
  • data-centric and real-time apps
  •  data-intensive applications.

How do Microservice and Node.js work simultaneously?

When both of these technologies are put together, they build scalable, flexible, and efficient applications. Node.JS is used for building microservices, it enables developers to build scalable apps that can handle a massive amount of user requests and can communicate with external APIs. 

The biggest advantage of Node.JS is that it has a flexible architecture that allows it to create microservices that can be developed, deployed, and scaled independently. These microservices are integrated with Node.js to help organizations utilize the resources at full capacity. These two are integrated by a range of tools that include API gateways, service registries, and many other technologies. Thus, making the whole system more resilient, efficient, and scalable.

How to Implement Microservices With Node.js?

In this blog, we will explore how to build a language translation microservice with Google Translate API. To make this easier for you, we have divided the whole process into the steps mentioned below:

  1. You have to start by signing up for a Google Cloud Console. You can sign up for free at https://cloud.google.com/free/.
  2. The next step is to enable Google Translate API. To enable the Google Translate API in the Google Cloud Console, you must follow the steps listed below:
  • Go to the Google Cloud Console webpage.
  • Choose your project or you can create a new one.
  • Go to the navigation menu button and click on the API & Services that are on the dashboard.
  • Click on Enable APIs and Services.
  • Find Google Translate API and click on it.
  • Choose or click on Enable.
  • Next is to generate an API key, you can do that by clicking on Credentials. Then click on Create Credentials.
  • You have to copy the API key that is used in the application, later on.
  1. After you have successfully enabled Google Translate API, you have to move on by creating a new node.js project. You can start creating by giving this command: 

   “ mkdir translation-microservice 

        cd translation-microservice npm init

 npm init “

  1. Install Dependencies by running the following command: 

“ npm install express axios” 

  1. Review the JSON file
  2. Set up the Server & Create The JS File
  3. Set up the Environment Variable
  4. Set Up The Client Side
  5. Start the Server
  6. Test the Microservice

What are the Benefits of using Microservices And Node.js?

  • Smooth development for complex applications

Large operations systems are difficult to analyze and develop. But, when you divide the systems into smaller units with microservice, this makes it easy to update and maintain. You can save time and cost as you only have to update the component that you need or require.

  • Develop well-designed apps

Using node.js microservices, you can design new features and can bring on innovative changes in the current architecture. These microservices also help with coding that meets the development standards and eliminates architectural issues.

  • Performance & scalability

Node.JS and microservices are known for building highly-scalable apps, you can use the desired resources to enhance performance and scalability. 

  • Easy to maintain

Using node.js microservices together will lead to a smoother and easier update.

  • Allows reusing of codes

Node.js promotes the idea of promoting the code into smaller, reusable components. This means that developers only have to write code for one time and they can apply it to multiple projects, leading to cost savings and time effectiveness.

  • Cost-effective

It is cost-effective because of having a lower infrastructure cost. Moreover, it has the ability to handle numerous customer requests with limited resources. You can also run the same application on other servers, making it the most cost-effective method.

It is an open-source platform which means developers can work on this without subscribing or paying a single penny. This platform also provides many useful resources that can help developers.

  • Follows a business-centric approach

Node.JS microservices fulfill the needs of changing business environments. It has essential features that help developers to build applications that meet business goals and future objectives. This approach allows businesses and organizations to create the small, required services that can be developed and deployed independently, enhancing business performance, efficiency, and productivity.

Pros of using Microservice node.js

  • It helps to manage traffic and is specifically designed for huge user bases.
  • It provides scalability for all types of services
  • It is known for its superior performance
  • It is cost effective
  • It is easier to maintain and update
  • Supports API
  • It has larger community support
  • Its frameworks are easily available
  • It has a simple modular development
  • It is easier to execute and has readable learning curves

Cons of using Microservice node.js

  • As microservices are continuously increasing, that has made the architecture complex and difficult for users to manage.
  • Network failures and delays cause a hindrance in the efficient workflow.
  • Developing and testing microservices needs more resources.
  • It provides limited language support
  • It has some security vulnerabilities

Why Should You Opt for Node.js Microservices? 

  • Superior performance
  • Faster execution
  • Cost-effective and scalable
  • Easy to maintain and update
  • Simplified, modular development
  • API support
  • Wider community support
  • Easily available frameworks
  • Easy learning curve


Node.js microservices can be of great help to custom mobile app development companies. These companies can use microservices node.js to create a responsive mobile app to meet the needs of potential customers. When node.js is used collectively with microservices, a developer can easily handle the complexities and can break the application into smaller components, making maintenance easy. This will further enhance the app’s performance and scalability. 


Q1 Is Node.js good for microservices?

Yes, it is a perfect choice for microservices as it offers to increase performance, it is highly scalable and easy to maintain.

Q2 How do you become a master in microservices?

To become an expert in microservices, you can follow the steps mentioned below:

  • Separate data storage for each microservice.
  • Maintain code quality and readability
  • Separate build for each microservice.
  • Deploy into containers.
  • Treat servers as stateless.

Q3 How to build a microservices architecture with node js to achieve scale?

  • Build microservices with Node. JS
  • Assess the business needs
  • Initialization
