Algolia is pretty much like Solr, you need to add data to it's index.

I have done a small integration of Algolia with AEM using JAVA API, we can have React API's as well to handle the requests.
Detail information can be found on the Algolia's documentation page. You can check out my blog as well on the integration and initial setup :
Thank you for this information!
