Angular continues to rapidly evolve, gathering around it one of the most active and friendly developer communities. A distinctive feature of this community is a special focus on architecture, strict typing, and thoughtful approaches to code organization. This is precisely why many enterprise teams choose Angular to build complex and scalable projects. However, as project complexity grows, new technical challenges emerge that require special approaches and deeper analysis.
In this article, we’ve collected proven practices and recommendations that we hope will be useful for Angular developers. We’ve taken the community’s experience into account and aimed to make the OneEntry platform a tool that fully meets its expectations and high development-quality standards.
Typical challenges in the Angular community
a) Integration with external backend, authorization and state management
Integration of Angular applications with backend services is a critical aspect, especially in enterprise and large-scale products. Developers often point out that simply connecting to REST or GraphQL APIs doesn’t resolve all tasks, as far more effort goes into carefully structuring data, handling errors, and maintaining strict typing, without which a project quickly becomes difficult to support.
Authentication and user access control turn out to be particularly challenging. Despite the existence of specialized solutions such as Keycloak, Angular developers still have to spend significant time fine-tuning integration, managing JWT tokens, refresh sessions, and secure client-side data storage. Issues related to proper state management and real-time data synchronization also continue to pose difficulties, particularly in larger teams where tight coordination between frontend and backend developers is required (source 1 | source 2).
All these tasks demand not only technical knowledge but also careful planning of an integration system capable of adapting flexibly as the application grows and evolves.
b) Performance, subscription management and project architecture
When it comes to Angular application performance, the community pays special attention to properly working with the RxJS library, which has become an essential part of modern frontend development. However, incorrect or insufficiently deep understanding of streams and subscription mechanisms often leads to hidden issues such as memory leaks and excessive CPU load, especially in large and dynamically updated applications.
Additionally, the lack of a thoughtful approach to lazy loading of components and modules negatively affects performance, increasing application load times and reducing the quality of user experience. Improper typing, particularly overuse of the any type, further exacerbates these problems, complicating subsequent maintenance, debugging, and refactoring of the code.
Ultimately, these mistakes not only degrade application performance and stability but also significantly limit their scalability and further development opportunities (source).
c) Application structure and standalone components
With the release of Angular 17, the framework fully transitioned to using standalone components, offering developers the option to abandon the classic application structure based on NgModule. This approach significantly simplifies working with small and medium-sized applications, making their architecture clearer and more flexible. However, in more complex, enterprise-level projects, such a transition required serious rethinking of modularity approaches and backend logic integration.
Standalone components simplify local development and testing, but when interacting with large external systems such as CRM, ERP, or authorization systems, developers face the need to maintain a high degree of modularity and logic encapsulation. The absence of the standard approach previously provided by NgModule forces teams to search for their own solutions, leading to fragmentation within the community and requiring additional architectural planning.
Therefore, despite its attractiveness, the move to standalone components created a new challenge: the necessity of balancing local development convenience with strict modularity and external system integration requirements (source).
Best practices for integrating REST and real-time data in Angular
To efficiently work with external APIs and real-time data, Angular developers employ a range of proven approaches and architectural solutions. These methodologies have emerged from years of community experience and help create reliable, performant, and easily maintainable applications:
• Creating separate service layers for API request handling.
Using services allows centralized management of requests, simplifies testing, and improves code readability. Clear separation between the service layer and components helps avoid code duplication and makes the application architecture clearer.
• Using Apollo Angular for GraphQL integration.
Apollo Angular has proven itself as a powerful tool simplifying GraphQL API integration due to built-in caching, convenient state management, and automatic query typing. This significantly reduces the amount of manual code written and improves performance by optimizing data handling and minimizing unnecessary network requests.
• Implementing JWT authentication using middleware and interceptor.
JWT has become a de facto standard in ensuring Angular application security. The use of interceptors and middleware allows automatic addition of authorization headers to requests and centralized error handling, significantly reducing the risk of duplicated logic and enhancing application security (source).
• Optimizing project structure through lazy loading and strict typing.
Applying lazy loading allows modules to load only as needed, significantly accelerating initial application load and improving user experience. Strict typing helps avoid numerous development-stage errors and simplifies code maintenance. It’s especially important to avoid using the any type, as it leads to loss of data control and complicates refactoring (source).
Applying these practices not only makes applications more efficient and performant but also simplifies their further scaling and support, especially in large teams and enterprise projects.
Advantages of Custom Modules and OneEntry integrations
One of the key features of the OneEntry platform is Custom Modules, which allow developers to implement individual backend business logic beyond the standard functionality of the platform. With this approach, teams can easily create specialized scenarios and adapt the application to unique business requirements without modifying the core architecture.
Custom Modules are developed as independent backend services and are then integrated into OneEntry using ready-made deployment mechanisms (Git, containers, environment variables). This approach maintains centralized management and application stability and eliminates the need to modify the base data structure and integrations. As a result, developers can quickly add new functionality and flexibly extend product capabilities without the costs of architectural rework.
Equally important are integration modules. OneEntry provides the ability to easily and quickly integrate any external systems such as CRM, ERP, accounting, logistics, and many others through a convenient Low-code interface. This allows teams to connect third-party solutions in just a few steps, significantly reducing the technical burden on developers and accelerating integration launch processes.
Key advantages of the OneEntry platform:
- ✅ Simplified integration of backend logic and external services: developers can quickly and efficiently implement complex business processes and external interactions, minimizing maintenance and update costs.
- ✅ Flexible management of authorization and user roles: built-in access control tools make it easy to configure user roles and permissions, eliminating the need for teams to develop separate authorization systems or integrate complex solutions like Keycloak. As a result, the launch of new functionalities is greatly accelerated, and a high level of application security is ensured.
By using the OneEntry platform, Angular teams receive a tool that allows them to fully focus on developing functionality and solving business tasks, while avoiding typical complexities related to integration and backend system maintenance.
What to consider when using OneEntry in Angular projects
In the process of working with OneEntry, teams discover various techniques and architectural solutions that help more effectively leverage the platform’s capabilities. Below are some observations and recommendations based on real-world cases:
• Managing RxJS subscriptions (unsubscribe() and takeUntil())
OneEntry supports real-time updates via events, and when actively working with data streams, it is especially important to manage subscriptions. Methods such as unsubscribe() and takeUntil() help prevent memory leaks and reduce client load, especially in long-lived components or during frequent view switching. This is particularly relevant for applications using WebSocket subscriptions, push notifications, or data streaming.
• Lazy loading and standalone components
Using lazy loading helps accelerate the initial application startup and reduce bundle size. Transitioning to standalone components in Angular 17 also allows avoiding excessive modular overhead, making the project structure more flexible. In combination with OneEntry, this provides good isolation of logic and components, allowing you to load only the parts needed in specific sections or micro-frontends.
• Centralized error and UX-response handling through interceptors
Although the OneEntry SDK handles authorization itself, you can use Angular interceptors to handle specific responses: for example, displaying error messages, logging, and handling response codes such as 429, 403, 500, etc. This makes the user interface more robust and transparent for users.
• Contextual use of the SDK client
The OneEntry SDK integrates easily with Angular Dependency Injection (DI). It is recommended to wrap client initialization into a service that provides methods for accessing entities, events, and custom modules. This makes the SDK easily scalable, convenient for mocking, and testing.
• Encapsulation of logic into separate feature modules
Even when using a standalone approach, it makes sense to group logic related to specific entities (such as orders, users, products) into separate directories with their own services, components, and OneEntry access. This helps maintain clean architecture and simplifies project scaling.
By following these recommendations, you can effectively utilize OneEntry’s capabilities, ensuring high quality, performance, and ease of further maintenance and expansion of your Angular application.
