Plugins
Plugins are an extensible way to add functionality to tippy instances. By splitting functionality into a plugin, components or routes that don't need the plugin are not burdened with its bundle size cost.
#Exported plugins
These plugins are exported by the package:
animateFill
🖌️followCursor
inlinePositioning
sticky
import 'tippy.js/dist/backdrop.css';
import 'tippy.js/animations/shift-away.css';
#Usage
#CDN (iife)
Included plugins (part of the All Props table) will work as normal.
tippy(targets, {
followCursor: true
});
#Node (esm or cjs)
import tippy, {followCursor} from 'tippy.js';
tippy(targets, {
followCursor: true,
plugins: [followCursor]
});
#Creating your own custom plugin
A plugin is created by defining an object with the following shape:
const plugin = {
// Optional (if the plugin provides a prop to use)
name: 'propName', // e.g. 'followCursor' or 'sticky'
defaultValue: 'anyValue',
// Required
fn(instance) {
// Internal state
return {
// Lifecycle hooks
};
}
};
The plugin's function fn
returns an object of
lifecycle hooks.
Here's an example of a plugin that causes a popper to hide if no elements within it are in focus (for interactivity):
const hideOnPopperBlur = {
name: 'hideOnPopperBlur',
defaultValue: true,
fn(instance) {
return {
onCreate() {
instance.popper.addEventListener('focusout', event => {
if (
instance.props.hideOnPopperBlur &&
event.relatedTarget &&
!instance.popper.contains(event.relatedTarget)
) {
instance.hide();
}
});
}
};
}
};
// Our new prop is enabled by default (defaultValue: true)
tippy(targets, {
plugins: [hideOnPopperBlur]
});
Plugins are invoked per-instance and the plugin function definition takes the
instance as an argument, so you can use private variables to create internal
state in the plugin closure. This is how the followCursor
plugin works.
#TypeScript
Types that take Props
(e.g. Tippy
, Delegate
, CreateSingleton
) are
generics that accept an extended props interface:
import tippy, {Tippy, Props, Plugin, LifecycleHooks} from 'tippy.js';
interface CustomProps {
myCustomProp: boolean;
}
type FilteredProps = CustomProps &
Omit<Props, keyof CustomProps | keyof LifecycleHooks>;
type ExtendedProps = FilteredProps & LifecycleHooks<FilteredProps>;
export const myCustomProp: Plugin<ExtendedProps> = {
name: 'myCustomProp',
defaultValue: false,
fn: () => ({})
};
export default (tippy as unknown) as Tippy<ExtendedProps>;
