Bundle Splitting in Angular

Bundle splitting is a technique used in Angular to optimize the loading performance of applications by splitting the code into smaller, more manageable bundles. This allows for faster initial load times and improved user experience.

Bundle splitting, also known as code splitting, is the practice of dividing your application's code into multiple bundles that can be loaded on demand. This helps reduce the size of the initial payload and allows parts of the application to be loaded only when needed.

• Improved performance: Reduces the initial load time by only loading the necessary code.
• Better user experience: Users can interact with the application faster.
• Efficient resource management: Loads resources only when required, reducing bandwidth usage.

Step-by-Step Process

1. Install Angular CLI (if not already installed):

npm install -g @angular/cli

2. Create a new Angular project:

ng new my-app

3. Navigate to the project directory:

cd my-app

4. Generate a new module with routing:

ng generate module lazy --route lazy --module app.module

5. This command creates a new module and sets up lazy loading for the routes.
6. Modify the generated module to include your component and services.

With lazy loading, the module will only be loaded when the user navigates to its route.

• Use lazy loading for feature modules to enhance performance.
• Keep your bundles as small as possible to minimize load times.
• Utilize Angular’s built-in optimizations and tools, such as the Angular CLI.
• Test your application’s performance regularly to identify and resolve bottlenecks.
