Micro-Frontends: The Future of ReactJS Development

Micro-Frontends The Future of ReactJS Development

ReactJS, an acclaimed JavaScript library for creating user interfaces, has been a revolutionary force in web development, allowing coders to craft dynamic and reactive single-page apps. As web applications become increasingly intricate and gargantuan, so do the obstacles challenged by development crews. Micro-frontends have appeared as a potent architectural method of tackling these issues. In this blog, we will explore the concept of micro-frontends and their part in the forthcoming ReactJS evolution, plunging into the importance of collaborating with a specialized ReactJS app development company and technical details to understand how they work and their benefits.

The Evolution of Web Development

The traditional paradigm of web evolution involves a monolithic model, where the entire front of the program is constructed as a solitary unit. While there are advantages to this method, it can be a significant impediment to progress when applications escalate in magnitude and intricacy. Adding more characteristics, the monolithic setup can cause prolonged growth spurts, advanced sustainment labor, and problems involving scaling and deployment.

The Concept of Micro-Frontends

Micro-frontends represent an architecture that accurately mirrors the idea of microservices, only for web applications’ frontend. Instead of fabricating one large, single frontend, the application is broken down into smaller, internalized frontend components, which are structured and delivered separately. Each module, or micro-frontend, can be imagined as a minor application that is accountable for a particular segment of the user interface.

Technical Details of Micro-Frontends with ReactJS

Module Isolation

The initial technical challenge in micro-frontends is isolating modules. It is essential that each micro-frontend can function autonomously without negatively impacting the other components of the software. React’s component-oriented framework is an ideal solution for this. It allows each micro-frontend to stand alone as a distinct React application, complete with separate components, states, and styles.

To ensure module isolation, React’s component arrangement offers encapsulation, preventing components from clashing with one another. In addition, CSS-in-JS libraries like styled-components or Emotion can help keep styles circumscribed to the pertinent details, diminishing the probabilities of style discrepancies between micro-frontends.


A vital part of micro-frontends is the communication between distinct components. When micro-frontends must distribute information or provoke activities across segments, there are various strategies to take into account:

  • Custom Events: Micro-frontends can make use of the CustomEvent API that is embedded in the browser to communicate among themselves. Though this technique is relatively uncomplicated and works well in simple scenarios, it might not be ideal for more intricate interactions. Partnering with a specialized ReactJS app development company can help businesses take full potential of this feature.
  • Shared State Management: Libraries like Redux or Mobx are valuable tools to manage universal information across micro-frontends. A core state repository can be initiated, and respective micro-frontends can deliver and register activities to align data.
  • Cross-Origin Communication: For micro-frontends existing on disparate domains or subdomains, techniques like Cross-Origin Messaging and CORS headers must be employed to establish secure data communication. These Cross-origin interaction practices make sure that the exchange of data proceeds in a safe manner.


In a micro-frontend setup, routing plays a pivotal role. Each micro-frontend should have its routing capabilities, enabling it to administer its routes and exhibit the befitting content. Libraries such as React Router can be exploited in each micro-frontend to administrate its routing autonomously.

For the primary application wrapper, a topmost router can control the routing for all the micro-frontends. The wrapping router supervises transformations in the URL and allocates to the pertinent micro-frontend following the path.

Deployment and Versioning

Micro-frontends are usually deployed in isolation, which brings about issues related to version control and harmonization. It is of utmost importance to establish a plan for overseeing different iterations of micro-frontends and ensuring the whole application is still cohesively linked.

Semantic versioning helps communicate alterations plainly when applied to micro-frontends. Further, automated and integration testing tools and procedures can assist in detecting compatibility problems earlier.
