Angular in Micro Frontend Architecture: A New Era for Web Development

Previously, front-end web development was comparable to constructing an enormous skyscraper all at once. This method frequently resulted in inefficiencies and complications, especially for large-scale teams and projects. Nowadays, though, it’s more like building with LEGO bricks thanks to micro frontend architecture Angular. In other words, before being assembled, each component can be constructed and tested independently.

In addition to improving scalability and flexibility, this modular approach speeds up software development cycles and simplifies cooperation.

You will learn everything there is to know about micro frontends and their significance in this blog. Additionally, we will explore the usefulness of module federation and walk you through putting it into practice to build strong Angular micro frontend architecture designs.

Let’s get started!

What is Angular Micro Frontend?

Understanding what micro frontend architecture Angular is is essential before delving into Angular’s function.

Angular Micro Frontend refers to a modern approach where a single web application is divided into smaller, independently deployable modules using Angular. This technique allows teams to develop, test, and deploy different parts of an application independently, promoting faster updates and efficient collaboration.

In micro frontend Angular architecture, each module or “micro frontend” operates as a self-contained application but integrates seamlessly into a larger system. For instance, one team could manage the user interface, another the payment system, and another the dashboard, all using Angular frameworks.
A key benefit of micro frontend Angular architecture is its scalability. The finest tools and frameworks for particular functionalities can be selected by teams by segmenting a huge monolithic program into smaller sections. Additionally, it reduces interdependence, strengthening the system and lowering the possibility of widespread problems.

This architecture is particularly useful for large-scale applications with multiple developers, ensuring modularity and improving development speed while maintaining Angular’s efficiency and performance for building dynamic web applications.

Let’s unravel a few more details!

Angular’s Function in Micro Frontends

The well-known frontend framework Angular for front end offers a powerful toolkit for developing dynamic, one-page applications. Angular’s well-structured architecture, powerful tooling, and TypeScript integration make it an excellent choice for developing small frontends.

Angular supports the micro frontend framework ecosystem in the following ways:

Modular Structure

Hire Angular developers who can quickly integrate applications into a bigger micro frontend architecture by breaking them down into distinct modules using Angular’s built-in modularity. Angular modules facilitate the management of separate micro frontends by providing a clear separation of concerns.

Lazy Loading

Micro frontends can only load when required thanks to Angular’s lazy loading capability. Performance can be greatly enhanced by loading each micro front end architecture as needed, especially for large applications.

Injection of Dependency

The strong dependency injection mechanism of Angular guarantees the effective management of shared services and modules across several micro frontends. This facilitates code reuse, which lowers duplication and improves the architecture’s long-term maintainability.

Micro Frontend Architecture’s Advantages

The following are the top six benefits of micro frontend architecture:

• Separation of Concerns and Modularity: Using micro frontend architecture Angular, a large monolithic application may be split up into smaller, independent modules. Each module manages specific features, which allows teams to work autonomously. This setup minimizes conflicts between teams, as each module functions independently. It also enables faster iteration, allowing teams to make updates and improvements more efficiently.
• Independent Development and Deployment: With micro frontends, multiple teams can work on distinct modules at the same time. Version control, deployment pipeline, and development lifecycle can all be unique to each micro frontend. This allows for more frequent releases and quicker development cycles without affecting other program components.
• Better Collaboration: With distinct module boundaries and interfaces, it improves collaboration. This prevents overlap and enables teams to concentrate on their areas of competence. Therefore, code reuse and consistency are improved when components and services are shared among micro frontends.
• Scalability: It makes horizontal scaling easier by enabling separate module scaling according to resource needs and usage trends.
• Flexibility in Technology: It allows for flexibility in technical options because each micro frontend can be built using a different frontend framework or library. This keeps the application’s user experience consistent while allowing teams to take advantage of the advantages of various tools and technologies.
• Fault Tolerance and Isolation: It encourages module isolation, lessening the effect of problems or failures in one module on the application as a whole.

What are The Best Practices of Angular in Micro Frontend Architecture?

In order to guarantee seamless integration, scalability, and maintainability, developers should adhere to specific best practices when implementing Angular micro frontends.

Domain Separation That Is Clear

Every micro frontend ought to manage a certain domain or feature. To avoid dependencies that could compromise the advantages of independence, keep micro frontends from overlapping.

Common Libraries

Use shared libraries for shared functionality across different micro frontends. For instance, shared modules can be used to centralize analytics, logging, and authentication. Sharing these web app development services is made easier by Angular’s dependency injection mechanism.

Strategies for Version Control and Deployment

Make sure that every micro frontend is deployed and versioned separately so as not to interfere with other application components. The deployment procedure for micro frontends is streamlined by Angular’s capacity to produce modular builds.

Employ the Federation Webpack Module

Building micro frontends is made easier by Webpack’s Module Federation, which enables dynamic imports of separately deployed modules. Because it facilitates smooth integration and sharing between several micro frontends, this method is quite advantageous when utilizing Angular for micro frontends.

Which Angular Alternatives Are There For Micro Frontends?

Although integrating Angular with Micro frontends offers developers several benefits, it’s crucial to prevent black vision. Because each project is unique, it is equally necessary for developers to investigate various frameworks and methodologies. There are benefits to combining Angular with micro frontends, but it’s important to weigh your options. Finding the best fit for your project requires it.

Single-Page Applications

When creating single-page applications, developers often rely on popular frameworks. These include Angular, React, or Vue.js. These frameworks allow developers to change content dynamically as users interact with the application. This approach eliminates the need for a full-page reload, creating a smoother experience. It also reduces load times, enhancing performance and user engagement. A highly straightforward and seamless user experience could result from a single HTML page. Although an SPA built with React, Angular, or Vue.js might provide a great user experience, developers need to consider scalability beforehand.

Monolithic Architecture

Monolithic designs can initially facilitate development. At first glance, it seems helpful that you have all of your code in one location. However, things can become complicated when your application expands and the codebase changes. Additionally, developers have a terrible time maintaining the code.

Other Frameworks

When it comes to front-end development, the community frequently discusses Angular. However, we cannot overlook React and Vue.js. These frameworks are also excellent options, and each has a devoted following. Both are capable of performing on par with Angular development services, particularly in Micro frontend settings.

Case Study: Using Angular Micro Frontend in Practice

Seeing how some of the biggest names in tech are using Angular with micro frontend architecture Angular to increase the modularity and scalability of their applications is intriguing. A few notable Micro frontend architecture Angular examples that highlight this trend are as follows:
