JSON:API Sparse Fieldsets for Drupal 8, 9, and 10

By default, the JSON:API returns all the available data for an object in its response. Using JSON:API sparse fieldsets you can increase the performance of your consumer application by reducing the fields in the returned response object to just those that you need.

In this tutorial, we will learn how to reduce the output to get exactly the information that we need from the API.

This is one of the most important features of modern APIs like JSON:API.

By the end of this tutorial, you'll know what sparse fieldsets are, the role they fulfill, and how to use them when requesting data from a JSON:API server.
