Optimize Bundle Size

This skill helps users minimize their application's bundle size when using Ignite UI Web Components by importing only the components they need and following best practices for tree-shaking.

Example Usage

• "My bundle size is too large"
• "How do I reduce the size of igniteui-webcomponents?"
• "Import only the components I need"
• "Tree-shake unused components"
• "Optimize imports for production"

When to Use

• User's bundle size is too large
• User wants to optimize for production
• User is importing more components than needed
• User asks about tree-shaking or optimization
• User wants to improve load times

Key Principles

1. Import only what you use - Don't use defineAllComponents()
2. Use named imports - Enable tree-shaking
3. Analyze your bundle - Identify what's being included
4. Lazy load when possible - Load components on demand

Import Strategies

❌ Bad: Import Everything

// DON'T DO THIS - imports ALL components (~500KB+)
import { defineAllComponents } from 'igniteui-webcomponents';

defineAllComponents();

Impact: Includes all 60+ components whether you use them or not.

✅ Good: Import Specific Components

// DO THIS - import only what you need
import {
  defineComponents,
  IgcButtonComponent,
  IgcInputComponent,
  IgcCardComponent
} from 'igniteui-webcomponents';

defineComponents(IgcButtonComponent, IgcInputComponent, IgcCardComponent);

Impact: Bundle includes only 3 components and their dependencies.

React Applications

If you're using React, consider using the igniteui-react package instead of igniteui-webcomponents. It provides the same components with React-friendly wrappers and typically results in better tree-shaking:
