Contentful Listener

The Contentful listener listens for content changes in Contentful and invokes the provided callback when such changes occur.

Usage:

import { ContentfulListener } from '@stackbit/contentful-listener';

const contentfulListener = new ContentfulListener({
    spaceId: process.env.CONTENTFUL_SPACE_ID,
    accessToken: process.env.CONTENTFUL_PREVIEW_API_KEY,
    environment: 'master',
    host: 'preview.contentful.com',
    pollingIntervalMs: 1000,
    callback: (result: CallbackResponse) => {
        // Do something
    }
});

The result is a an object having the following interface, very similar to Contentful's Sync API response:

export interface CallbackResponse {
    entries: Array<Entry<any>>;
    assets: Array<Asset>;
    deletedEntries: Array<Entry<any>>;
    deletedAssets: Array<Asset>;
}
