Chapter 3: Sourcing and Querying Data (from Anywhere!)
In this chapter, you will learn about Gatsby's data layer. You will start by understanding what we mean by data in the context of Gatsby before learning the basics of GraphQL. Once you have this understanding, you will learn how to source and query data from local files. We will then look at sourcing data from a couple of Headless CMSes.
In this chapter, we will cover the following topics:
- Data in Gatsby
- Introducing GraphQL
- Sourcing and querying data from local files
- Sourcing and querying data from a Headless CMS
