VueJS - Slots and Scoped Slots
Using Slots and Scoped Slots
Slots in VueJS allow you to create reusable components with flexible content. Scoped slots provide a way to pass data from a child component to the slot content in the parent. This guide covers the basics of using slots and scoped slots in VueJS.
Key Points:
- Slots are placeholders for content that is passed from a parent component to a child component.
- Scoped slots allow a child component to pass data to the parent component's slot content.
- Using slots and scoped slots can help create more reusable and flexible components.
Basic Slots
Default Slot
The default slot allows you to pass content from the parent component to the child component:
This is passed to the child component
Named Slots
Named slots allow you to define multiple slots with different names and pass content to them:
Header Content
Footer Content
Scoped Slots
Using Scoped Slots
Scoped slots allow a child component to pass data to the parent component's slot content. This is useful for creating reusable components with flexible templates:
{{ slotProps.text }}
Using Multiple Scoped Slots
You can define and use multiple scoped slots in a single component:
{{ slotProps.title }}
{{ slotProps.footerText }}
Fallback Content
Slots can have fallback content that is displayed if no content is passed from the parent component:
Default fallback content
Best Practices
Follow these best practices when using slots and scoped slots:
- Keep Slot Content Simple: Keep the content within slots simple and focused on its purpose.
- Use Named Slots for Clarity: Use named slots to clarify the purpose of each slot and make the template easier to read.
- Provide Fallback Content: Provide fallback content for slots to ensure the component behaves as expected even if no content is passed.
- Document Scoped Slots: Document the props provided by scoped slots to make it clear what data is available for use.
- Avoid Overusing Scoped Slots: Use scoped slots judiciously to avoid adding unnecessary complexity to your components.
Summary
This guide provided an overview of using slots and scoped slots in VueJS. By understanding and utilizing these features, you can create more reusable and flexible components that allow for better customization and data management.
