Introduction
As modern web development moves toward headless architecture, GraphQL is fast becoming a key player in content querying. If you're using Sitecore JSS, GraphQL opens up a powerful and flexible way to interact with your content tree—faster than REST and far more intuitive. This blog post is the first in our series on mastering GraphQL with Sitecore JSS.
What is GraphQL?
GraphQL is a query language for APIs and a runtime for fulfilling those queries with your existing data. Unlike REST, which returns fixed data structures, GraphQL allows clients to specify exactly what they need—nothing more, nothing less.
GraphQL vs REST
Why GraphQL in Sitecore JSS?
Sitecore JSS (JavaScript Services) supports headless development by enabling frontend developers to use modern frameworks like React, Angular, or Next.js while still tapping into Sitecore's powerful backend. GraphQL serves as the data layer between the JSS app and Sitecore content, offering several advantages:
Efficient data fetching
Clear documentation through introspection
Fewer round-trips to the server
Better control of nested content structures
How Sitecore Exposes GraphQL
Sitecore exposes GraphQL endpoints via the Sitecore GraphQL API, which is available with the Headless Services package. Here are some key points:
Authentication: Typically via API key
Schema: Auto-generated based on your content tree and templates
You can use tools like GraphiQL, Altair, or Postman to test and run your queries.
Sample Query: Fetching a Page Title
query {
item(path: "/sitecore/content/home") {
name
displayName
field(name: "Title") {
value
}
}
}
This fetches the name, display name, and custom Title field of the Home item.
