How To Design Angular App Architecture

Background Information

Angular is a powerful front-end development framework released by Google in 2010. It is used to design complex scalable web and mobile applications. As a JavaScript-based application development platform, Angular provides a Model-View-Controller (MVC) architecture to design applications with a well-structured architecture. This helps developers to create applications with a better code structure and balance the responsibilities of different components across the application. The goal of the Angular app architecture is to simplify the process of web development and ensure the project is easier to maintain and scale.

Defining Components of the App Architecture

Developers typically begin the design process by thinking about the components of the application. It is advisable to use Atomic Design techniques to define the elements in the application architecture. Here, the components in the app architecture should be defined into atoms, molecules and organisms. Atoms are the smallest components which are independent and can’t be divided. The molecules are composed of molecules, which can be combined and recombined in different ways. And finally, organisms are the combinations of atoms and molecules that make the application.

Modular Approach

The next step in designing the Angular app architecture is to take a modular approach. This means that the application should be structured in such a way that it can be easily divided into smaller and more manageable parts. Modularization means that developers can create components in the application that can be reused in different parts of the application. This helps to build a more maintainable and scalable application which is easier to test, debug and extend.

Separating the Logic

The architecture can be further improved by separating the logic from the components. This means that the logic necessary for the application should be kept away from the components, which are the user interface (UI) elements. This separation allows developers to reuse the logic without having to rewrite it for each component. It also helps to ensure that the logic remains clean and abstracted from the UI, which makes it easier to maintain, debug and extend.

Data Flow

A good Angular app architecture should be designed such that data flow between components is managed efficiently. This can be achieved by using a state management system such as NgRx or Redux. State management libraries are used to manage the application state and the data flow between components. This ensures that data is kept in a single source of truth and makes it easier to debug and maintain the application state.

Testing the Architecture

It is important to ensure that all components of the application are thoroughly tested before making them live. Automation testing should be carried out using frameworks such as Protractor and Jasmine, which allow developers to easily test the application. Automated testing helps to identify problems in the architecture and to ensure that the application is working as intended.

Implementation Guidelines

The final step in designing the Angular app architecture is to develop a set of implementation guidelines. This includes defining the conventions, patterns and tools to be used during the development process. These guidelines should be followed closely by the developers to ensure consistency. Developers should also be mindful that the architecture should be adaptable to changes in the environment.

Managing Data

Data Management is one of the key components of a successful Angular App Architecture. Developers should use libraries such as AngularFire which provide features like Firebase authentication and data storage in order to manage data and ensure consistent and secure data access.

Handling Errors

Errors are an inevitable part of application development, and a good Angular app architecture should be designed to handle them effectively. Developers should use libraries such as AngularJS error handling that provides features such as error logging and reporting. This helps to ensure that the application is robust and can handle any unexpected errors that may arise.

Component Reutilization

Reutilization of components is also key in designing a successful Angular App Architecture. Developers should use tools such as Angular CLI or Npm to build components which can be used across multiple applications. This helps to ensure that the code is efficient, maintainable and reusable.

Integrating Third-Party APIs

Many applications require integration with third-party APIs. Angular applications should be designed to allow for integration with third-party APIs. This can be accomplished by using libraries such as Axios and Angular HttpClient. These libraries provide features such as authentication and request management, which make integrating with third-party APIs easier.

Analytics and Performance Monitoring

Analytics and performance monitoring are essential for tracking the usage and performance of an Angular application. Developers should employ tools such as Google Analytics and New Relic to monitor the performance of the application and track usage. This helps to ensure that the application is meeting user expectations and is optimized for performance.

Securing Data

Data security is essential for any application. Developers should use tools such as the Angular Security library to ensure that the application is secure and the data is protected. This library provides features such as encryption, authentication and access control which can be used to protect the application.


Maintainability is also an important aspect of designing an Angular App Architecture. Developers should use best practices such as using a linter and embracing automation to ensure that the code is well-structured and maintainable in the long run. This helps to ensure that the code is easily upgradable and extensible.

Design Patterns

Design patterns are reusable solutions for commonly arising problems in software development. In designing the Angular app architecture, developers should make use of well-known design patterns such as the Model-View-Controller (MVC) and Model-View-ViewModel (MVVM) patterns. This helps to ensure that the code is structured and easy to maintain.

Application Structure

The application structure of the Angular app should be organized in such a way that the components are cohesive and that all the application code can be easily located. This can be achieved by using the component-based architecture. Followed properly, this helps to ensure that the application code is easily readable, accessible and maintainable.

Generating Reports

Reporting is also a key component of a successful Angular App Architecture. Developers should use features such as server-generated PDFs to generate reports for end-users. This helps to ensure that the user’s data is presented in a clear and accessible format.

Auditing Performance

Performance auditing is another important component of an Angular App Architecture. Developers should make use of tools such as Fiddler to trace the application performance and identify and fix any issues. This helps to ensure that the application is performing optimally and that performance is not degraded over time.
