In this article, we'll look into how to integrate Sanity.io with Algolia. Sanity.io is a content platform that comes with an open source headless CMS that you can customize and a hosted real-time datastore that lets you read and update data. The philosophy behind Sanity.io is that you should be able to treat content as data and bring it to whatever product or application you have. A CMS normally doesn't come with search functionality, but the Algolia plug-in adds a flexible and feature-rich search functionality on top of your CMS. To integrate a CMS with Algolia, one can leverage webhooks by creating an API as a webhook endpoint and configuring the CMS to trigger it when content changes. The sanity-algolia library helps deal with this part by transforming the payload for the Algolia index and provides a flexible way to define which properties to fetch and how to transform them, making it easier to set up the integration.
