What Are Micro Frontends and Its Benefits in Web Development | Cyberinitiation

The Micro frontends extend the functionality of a microservice pattern to the front end. Web application UIs (front ends) are composed of semi-independent fragments by the Micro frontend as a new pattern that can be built by different teams using different technologies. Micro-frontend architectures are similar to back-end architectures where semi-independent microservices constitute the back ends.

Use of the Micro Frontend

Micro Frontend is a friendlier and less bulky one as Micro Frontend Architecture splits the entire application by business domain across the entire stack. Front-end teams are enabled by the same level of flexibility, testability, and velocity that backend teams actually get from Microservices. A front-end app is decomposed into individual, semi-independent “micro apps” by Micro-frontend architectures which is working loosely together. This can help make large projects more manageable, e.g. when transitioning from legacy codebases.

Micro Frontend Architecture

Microservice architecture is characterized by independent services focusing on a specific business function and maintained by small, self-contained teams. Web applications are develop by Microservice architectures, are use on AWS, and for good reason.

As microservices are distributed and communication between microservices with each other by inter-service communication will be on the network level. Each microservice has its own instance and process. Therefore, services must interact using an inter-service communication protocol like HTTP, gRPC, or message brokers AMQP protocol.

Essential components of Micro Frontend

Let’s observe closely the components of the architecture and their capabilities.

  • Microservices – They make up the foundation of a microservices architecture. …
  • Containers.
  • Service mesh.
  • Service discovery.
  • API gateway.

The requirement to create a microservice

When a module is in needs to have a completely independent lifecycle i.e. the code commits to production flow, microservice should come into use. Code repository, CI/CD pipeline should have their own, and so on. It is far easier to test a microservice by using a smaller scope.

Micro Frontend UI

This is a type of microservice that exists within a browser and these are sections of your UI, often consisting of dozens of components that use frameworks like React, Vue, and Angular to render their components. Microservices are independently manageable services that enable more and more services according to the need. The impact on existing service. To change or upgrade each service individually rather than upgrading the entire application is possible.


As one microservice can call another, the user should define whether a communication is synchronous or asynchronous. For web application communication, the HTTP protocol has been the standard for many years, and that is the same for microservices. By the failure of a single module, larger applications can remain mostly unaffected. In terms of eliminating vendor or technology lock-in, Microservices provide the flexibility to try out a new technology stack on an individual service according to requirement. Besides several advantages, the cost is a potential disadvantage of a microservices architecture. Communication between Services will be there, which results in a high volume of remote calls. Traditional architectures can increase network latency and processing costs.
