Content Projection in Angular 2025

Content projection is a powerful and flexible concept in Angular that allows developers to create reusable, customizable components by dynamically injecting content into them. This feature enhances modularity and promotes cleaner code. In this article, we’ll dive deep into the concept of content projection, its benefits, and practical implementation techniques.

What is Content Projection?

Content projection enables developers to pass HTML content from a parent component to a child component and display it dynamically. This is achieved using Angular’s <ng-content> directive, which acts as a placeholder for projected content.

Think of <ng-content> as a portal that connects a parent component’s template to a specific part of the child component’s template.

Why Use Content Projection?

Content projection is especially useful in scenarios such as:

1. Creating Reusable Components: It allows developers to build components like modals, tabs, or cards that are flexible and reusable.

2. Decoupling Logic and Presentation: Developers can separate the business logic of a component from its UI.

3. Improved Customizability: The parent component can inject content without modifying the child component.
