Is Node.js a Good Choice to Build an App for Microservices?

by Mariya Parackal

Microservices and Node.js have a strong relationship. Node.js was introduced to the app development world to enable the creation of microservices-based programs easier. The central concept was for breaking down Node.js apps into small, dispersed nodes that communicated with one another to make the whole thing work.

Microservices: What are they?

Microservices are a software architecture paradigm that breaks down large systems into a collection of small, simple apps or services. Smaller pieces of services or applications can then be easily maintained, tested, and loosely connected.

Following that, these applications are deployed independently in an orderly manner based on their business skills. Finally, business capabilities are established and articulated through business-oriented APIs, which encapsulate valuable business assets and system integrations, which are adaptable for use in many settings and can be reused based on need.

Apps used to be constructed as monoliths before the introduction of micro-services architecture. They continued to expand, posing issues in terms of maintainability. Splitting them up into smaller pieces, known as micro-services, was the logical option.

Tasks are not split or specified in a monolithic design. Fixing a login issue in an extensive application, for example, may necessitate a developer-first understanding of the entire codebase of the application, rather than just a straightforward operation.

Microservices Advantages

When developing apps, the technology used is less significant than the business rationale. The benefits of using microservices in an application development project are outlined below.

• Better Structure: It is usually easier to understand a well-structured app, making adding new features easier to develop and implement. As a result, business analysis takes up less time and money. As a result, developers devote more time to develop.

• Consistent Implementation of Complicated Products: Complicated applications are difficult to imagine, construct, and maintain. Micro-services, on the other hand, are broken down into smaller, more manageable chunks.

• Scalability: It’s tough to scale a monolithic program with a large blob of closely connected code since so much effort is wasted trying to figure out what’s going on within. With microservices, it’s easy to see which bottlenecks are present, making their removal easier.

• Fewer Errors: Finding defects in a monolithic architecture is difficult and time-consuming, whereas micro-services keep little pieces of technology with low errors and so are more controllable.

• Improved Performance: Because each micro-service only performs one task simultaneously, they are simple to tweak and optimize for work efficiency.

• Vendor lock-in Resistance: Different programming languages can be employed depending on the challenge, allowing for greater flexibility.

Today, numerous mobile app development frameworks are available to give you the best user experience. And these app development frameworks help developers to build mobile apps within a specific time and budget.

Understanding the Benefits of Node.js Technology

Node.js is an event-driven JavaScript runtime that may be used to create web-based applications that can be scaled. Microservice-based programs written in Node.js can provide several advantages, as outlined below.

• Stability and Scalability: The app will be stable and scalable indefinitely, depending on cost. One of the significant aspects of Node.js that enables this is its single-threaded asynchronous architecture, which spawns child processes for some asynchronous activities hidden from the programmer and runs deep behind the hood.

• Data Replication: It is the process of generating numerous copies of data and storing them in multiple places to improve network accessibility. This is a micro-services requirement and is simple with Node.js.

• Cost Control: Rather than developing a second copy of the app, as is the case with monolithic apps, a micro-service can be built that only copies the required parts, saving money.

• Easier updates and Maintenance: Unlike a monolithic system, where there is a large amount of code to deal with, adding a new feature is simple. The same is true of updates. Instead of investing in a large and costly code redesign, the system can be upgraded slowly. This technique is supported by Node.js, which enforces a service-based and modular application structure.

• Simplified Development Workflows: Unlike monolith, where developers rely on each other during app development, developers can work on their respective areas of the app independently. Because a large app is divided down into little chunks, it’s easier for developers to work on their sections independently without interfering with each other’s work. This is one of Node.js’ strengths.

We are looking into the cost of developing a mobile app by small to mid-size agencies or freelancers only. 

Microservices and Node.js


The best architectures to consider for developing complicated and high-traffic applications are Node.js and micro-services, as they make application development and maintenance easier than monoliths.
