PageManager.beforeFetchedRequest¶
PageManager.beforeFetchedRequest is an event on the Event Bus that occurs whenever a Turbo.before-fetch-request event is fired in a page. To read more about Turbo visit the Page Manager Api documentation
Event body¶
Visit a Turbo.before-fetch-request event documentation page to get the information about the data available as the event body.
Example¶
In this example we listen to PageManager.beforeFetchedRequest event and perform an action whenever it's emitted.
useStorefront(async (storefront) => {
storefront.eventBus.on('PageManager.beforeFetchedRequest', () => {
console.log('This fires before a fetch request is performed');
});
});
Example¶
In this example we use a Message Storage API to retrieve an array of past PageManager.beforeFetchedRequest events.
useStorefront((storefront) => {
const messageStorageApi = storefront.getApiSync('messageStorageSystemApi');
const pastBeforeFetchedRequestEvents = messageStorageApi.getChannelMessages('PageManager.beforeFetchedRequest');
if (pastBeforeFetchedRequestEvents.length > 0) {
pastBeforeFetchedRequestEvents.forEach(({ body: eventBody }) => {
console.log('perform action on every past event');
});
}
});
