In today's fast-paced digital world, enterprises face the challenge of creating large-scale, complex web applications that are flexible, maintainable, and scalable. One approach that has gained traction in recent years is the use of micro frontends. This architectural pattern allows for the development of independent, deployable frontend modules that can be integrated to form a cohesive user interface. When combined with Angular, a powerful frontend framework, micro frontends provide a structured way to build scalable enterprise applications. In this blog post, we'll explore how micro frontends in Angular contribute to building scalable enterprise-level applications.
Angular and Micro Frontends
Angular, a robust and widely adopted frontend framework, can be effectively used to create micro frontends due to its modular and component-based architecture. Each Angular application can serve as an independent micro frontend, encapsulating specific features or functionalities
How Angular Enables Scalable Micro Frontends
Now, let's delve into how Angular, when used for micro frontends, contributes to the scalability of enterprise-level applications:
Angular's modular architecture, through NgModules, allows developers to organize the application into cohesive, reusable, and independently deployable modules. Each module can represent a micro frontend, facilitating independent development, testing, and deployment. This modularity significantly improves scalability by enabling teams to focus on specific functionalities without affecting the overall application.
Angular's lazy loading feature ensures that micro frontends load only when needed, enhancing application performance. As users interact with the application, Angular loads the required micro frontend dynamically. This optimization ensures faster initial load times and improves the user experience, especially in large-scale applications.
State management is a critical aspect of micro frontends. Angular, using RxJS, facilitates efficient state management by enabling seamless communication between micro frontends. Observables and Subjects provided by RxJS allow for real-time updates and data synchronization across various components and micro frontends. This ensures a consistent and reliable user experience in a scalable environment.
Angular Elements enable the creation of standalone, reusable components that can be easily integrated into any application, regardless of the technology stack. Angular Elements provide a way to package Angular components as custom elements, allowing for smooth integration into existing micro frontend architectures. This flexibility enhances the maintainability and extensibility of the application.
Micro frontend architecture in Angular involves breaking down a large frontend application into smaller, independently deployable parts. Here's a simplified 5-step guide to help you set up a micro frontend architecture
Setting Up Micro Frontends in Angular: A 5-Step Guide
1. Create Micro Frontends
Start by creating individual Angular applications for each micro frontend. Use Angular CLI to generate a new Angular application for each micro frontend:
ng new micro-frontend-name
2. Define Boundaries and Responsibilities
Clearly define the boundaries and responsibilities of each micro frontend. Identify the specific features or sections of the application that each micro frontend will handle
3. Develop and Build Micro Frontends
Develop each micro frontend independently based on the defined boundaries. Implement the necessary features and UI components. Build the micro frontends using Angular CLI:
ng generate application micro-frontend1
ng generate application micro-frontend1
4. Integrate Micro Frontends in Shell Application
Create a shell application (the main container) using Angular CLI. Define integration points within the shell application where the micro frontends will be loaded. Use dynamic loading techniques to integrate the micro frontends into the shell application.
5. Host and Deploy
Host the built micro frontends on separate servers, domains, or subdomains. Ensure that each micro frontend is accessible as a standalone application. Thoroughly test the integrated application and deploy it, including all micro frontends, to the desired hosting environment.
Conclusion
Embracing the micro frontend architecture in Angular offers a well-structured approach to building scalable, maintainable, and flexible enterprise-level applications. Leveraging Angular's component-based architecture, lazy loading, efficient state management with RxJS, and integration flexibility with Angular Elements, enterprises can create independent micro frontends that seamlessly integrate to form a cohesive and scalable application
