How to render Dynamic Component in Angular 18

Introduction

In the fast-paced world of web development, the ability to create dynamic, user-centric interfaces is more critical than ever. Angular 18’s Dynamic Component Rendering offers developer’s powerful tools to adapt web applications based on real-time data and user interactions. At DJ Computing, we harness this technology to build flexible, high-performance web applications. This blog will explore how Angular 18's dynamic component rendering works and how DJ Computing implements it in real-time, ensuring responsive, modular, and scalable web solutions tailored to the needs of modern businesses.

Dynamic Dashboards

DJ Computing employs dynamic rendering to create personalized, user-driven dashboards. Based on user roles or permissions, specific components like graphs, analytics, or task lists are loaded at runtime. For example, a financial application might render performance charts for managers, while a regular user sees only their transactions and tasks. This modular and flexible UI management reduces the need for complex conditional logic in templates, focusing instead on dynamic runtime rendering of components.

User-Driven Interactions

In business and data-driven web applications, users often interact with forms and data that change based on real-time inputs. DJ Computing leverages Angular 18’s dynamic rendering to alter forms, buttons, and table components depending on the user’s data, preferences, or selections. This allows users to engage with the application in a more intuitive, context-aware manner, where they see only what’s relevant to them at that moment. For example, in CRM systems, certain fields in a contact form might only appear when a user selects a particular type of contact.

Improved Performance and Scalability

In Angular 18, lazy loading plays a critical role in boosting performance by loading components only when they are required. DJ Computing utilizes this feature to ensure that only essential UI components are rendered during the initial load, enhancing both performance and user experience in large-scale web apps. This makes the application lightweight and fast, as only necessary parts of the UI are rendered dynamically based on user interaction.

Modularity and Reusability

Dynamic Component Rendering promotes the reusability of web components. DJ Computing takes a modular approach by creating individual components that can be dynamically rendered across multiple pages or sections within the same web app. For instance, a product listing component can be reused across the entire e-commerce application but dynamically rendered with different configurations or data inputs depending on the category or user behavior. This reduces redundancy and simplifies long-term maintenance.

Real-Time Data Handling

In data-intensive web applications, DJ Computing integrates real-time data streams with dynamic component rendering. For example, in monitoring systems or stock trading platforms, data-driven components such as live charts or price tickers are dynamically rendered or updated based on incoming data feeds. This ensures that the application UI remains up-to-date without requiring manual refreshes, providing users with immediate, actionable insights.

Rendering components dynamically

To render the component, you need to make use of the ComponentFactoryResolver service. This allows you to create an instance of the dynamic component and inject it into the ViewContainerRef In your parent component (e.g., AppComponent), inject the ComponentFactoryResolver and use the directive to dynamically load the DynamicContentComponent

Conclusion

For DJ Computing’s web applications, dynamic component rendering in Angular 18 offers flexibility, scalability, and performance improvements. By loading components on demand and customizing the UI for each user, they provide a responsive, data-driven experience, which is critical in modern web app development.
