Component Settings
Settings allow you to configure your components with default and custom values. This lesson explains how to define settings, access them in your code, and modify them from outside the component.
Defining Settings
In component.js, you’ll notice:
- The
defaultSettings object defines initial values for settings
- Settings are passed to
createComponent as a parameter
- Settings are reactive by default, but aren’t Signal instances like state values
Using Settings in Components
Looking at our code:
- Settings are accessible in the
createComponent function
- Use them to customize component behavior without changing code
- Settings can be any type: strings, numbers, objects, or functions
Passing Settings via HTML
Settings can be provided when using your component:
- Basic settings as HTML attributes
- Complex settings (objects, arrays) via JavaScript
- Settings are great for making components reusable
Accessing Component Methods
The component() method provides access to a component instance:
- Access methods defined in
createComponent
- Call component methods from outside the component
- Modify settings at runtime with
settings()
Try It Yourself
Enhance the profile component to:
- Make the avatar image configurable via settings
- Add methods to update user information after creation
- Create a form that uses
component() to update the profile
