Micro Frontend is a frontend web development technique based on Microservice Testing. The current tendency is to develop a robust and feature-rich web application on Microservice architecture. Over time, the Micro Frontend Architecture becomes integrated into the program; it is often built by a different team, expands in size, and becomes more challenging.

How Does the Micro Frontend Work?

A cross-functional team creates features from start to finish, from the user interface to the database. Micro Frontend is a more user-friendly and compact version. Micro Frontend Architecture partitioned the application into business domains and distributed it throughout the entire stack. Moreover, this gives frontend development teams the same flexibility, testability as well as velocity that microservices allow backend teams.

Micro Frontend best practices, techniques, and recipes for developing a contemporary online application in collaboration with several teams and using a variety of JavaScript frameworks.

The fundamental premise of Micro Frontend Architecture is as follows:

• Maintain Technological Independence

Each team should choose and enhance the stack independently of the other teams. Custom elements enable the concealment of implementation details while maintaining a neutral interface for others.

• Distinguish Team Code

Never share a runtime environment, even if teams work with the same framework. Create a self-contained, self-contained application. Contrary to popular belief, do not depend on shared state or global variables.

• Create Prefixes for Teams

When isolation cannot be achieved, use naming conventions. To prevent clashes and establish ownership, namespace CSS, Local Storage, Events, and Cookies.

• Preference over custom APIs.

Instead of creating a worldwide PubSub system, communicate using browser events. If a cross-team API is required, make it as basic as feasible.

• Create a Resistant Web Design

Even if JavaScript is unable to run, the functionalities should be helpful. Utilize universal rendering and progressive augmentation to optimize perceived performance.

What are some of the best Micro-Frontend Practices?

Various techniques for implementing Micro Frontend Architecture-

• The Single page application meta-framework allows the mix of multiple development frameworks on the same page without refreshing the page, including React, Vue, Angular 1, Angular 2, & others.
• Numerous single-page applications host at distinct URLs. Utilize NPM or Bower components for apps that need standard functionality.
• Utilizing Windows to isolate Micro applications inside Iframes. To collaborate, use Post Message APIs and libraries. IFrames share the APIs that their parent window exposes.
• Modules communicate with one another using a standard event bus. Each module operates independently of the others to manage incoming and outgoing events.

Software Components Libraries App components and sections are organized into libraries based on the main app’s stack and “required” by the main app. This means that several components make up the main application.

Why Is Micro Frontend Important?

With the advent of new online applications in the modern-day, the front end has grown in importance, while the back end has diminished. The majority of the code dedicates to the Micro Frontend Architecture. Additionally, the monolithic technique does not scale well for more enormous online applications. When dealing with an extensive frontend application, a monolithic approach becomes unmanageable.

There must be a mechanism for decomposing it into smaller, self-contained components. The Micro Frontend is the answer to the issue. Micro Frontend programming is written entirely in pure JavaScript and can be moved across any JavaScript framework.

What are the Advantages of a Micro frontend Architecture?

Each day, a new JavaScript technology is created, and the number of these technologies is expanding quicker than the speed of light. That may be annoying at times since each JavaScript technology has its own set of advantages and disadvantages. And, while deciding on a specific technology, everyone weighs the potential advantage against the potential danger. Micro Frontend best practices enable the use of various approaches for a variety of services. Listed below are a few advantages of Micro Frontend:

• Support for code and stylistic separation, allowing each development team to use their preferred technology. The development and deployment cycles are pretty short.
• It is beneficial for Continuous Deployment.
• Testing becomes more straightforward, and you no longer must touch the whole program for each tiny change.
• Renovation of the Frontend – Improving new stuff becomes simpler.
• Increased Resilience and Ease of Maintenance.
• Isolate code and style.

Micro Frontend Architecture in Conclusion

Assemble the core and integration of Micro Frontend Architecture as simply as feasible. Standardizing UI-UX principles is a critical issue. A general option is to use a style guide, such as Material Design or Bootstrap. Communication with the team is critical to ensuring that everything runs well and establishing certain norms and regulations to reduce disagreements.

All these Micro Frontend Architecture best practices contribute to the resolution of a single issue: scalability. A rapidly growing application creates multiple challenges and conflicts, necessitating the division of code into teams and the proper logistics to give high-quality, technology-forward, and timely answers to the globe.
