Custom Hooks

This section provides in-depth information on the custom hooks used in the Akasha Core.

useRootComponentProps​

Manage and access props received by the root component. These props may contain the context of the plugins for routing, translation, and extensions. It also exposes some utility functions which may be used across the World.

For example, the worldConfig object can be used to access the configuration info related to the application's World. The navigateToModal method helps to load the matching modal from the modal params. The getCorePlugins method exposes the main plugins used in Core, such as the routing plugin, which is useful for navigation within an application.

info

This hook requires that the root component app be wrapped with the accompanying provider. The Akasha Core hooks package exposes a Higher Order Component called withProviders that takes care of this, in addition to other providers. Alternatively, you can also directly use the RootComponentPropsProvider required for the useRootComponentProps hook

Example usage

import { useRootComponentProps, RootComponentPropsProvider } from '@akashaorg/ui-core-hooks';

const Component = () => {
const {
   baseRouteName,
   uiEvents,
   worldConfig,
   getCorePlugins,
   getTranslationPlugin,
   navigateToModal,
   // ...
} = useRootComponentProps();

// get i18n instance from the translation plugin
const i18n = getTranslationPlugin().i18n

// handle navigation using the routing from core plugins
const handleNavigate = () => {
  getCorePlugins().routing.navigateTo({
    appName: 'applicaton namspace',
    getNavigationUrl: () => {
      // ...
    }
  })
}
}

export default <RootComponentPropsProvider><Component/></RootComponentPropsProvider>

useAnalytics​

Handle analytics in your applications

This hook is helpful in managing opt-in analytics functionality in a world.

Example usage

import { AnalyticsCategories } from '@akashaorg/typings/lib/ui';
import { useAnalytics } from '@akashaorg/ui-core-hooks';

const Component = () => {
const [ analyticsActions ] = useAnalytics();

const subscribed = true;

// handle navigation using the routing from core plugins
const handleTopicSubscription = () => {
  analyticsActions.trackEvent({
    category: AnalyticsCategories.FILTER_SEARCH,
    action: subscribed ? 'Topic Subscribed' : 'Topic Unsubscribed'
  })
