JSS GraphQL API
You can opt for using GraphQL when you set up your application with any of the Sitecore-provided tools for creating a JSS project.
GraphQL requires connected mode, headless connected mode, or integrated mode to work. If using the disconnected mode, your application's service factories must return REST services because the disconnected development server only emulates REST services.
Data available for GraphQL querying
You can fetch the following types of data using GraphQL:
If you are using JSS for Next.js, the sample application leverages the GraphQL Sitemap Service to fetch the list of site pages using the Sitecore GraphQL API when statically generating and exporting the Next.js app.
JSS applications can use the following GraphQL endpoints:
The Sitecore Experience Edge for XM GraphQL endpoint. It comes with a read-only GraphQL schema designed to accommodate common front-end use cases for headless Sitecore development. Read about the Experience Edge schema.
Sitecore Edge Preview GraphQL endpoint provided by Headless Services, an implementation of a GraphQL server on top of Sitecore that mirrors the Experience Edge schema.
If you created your JSS application with any of the Sitecore-provided tools for creating a JSS project and chose
GraphQL as your data fetching method, the JSS services use the Sitecore Edge Preview GraphQL endpoint.
To change the GraphQL endpoint used by your application:
In the root directory of the JSS application, in the
package.jsonfile, in the
configmap, find and update the
Using GraphQL in JSS applications
JSS apps offer several choices in terms of using GraphQL.
The other option is to use the Integrated GraphQL in JSS apps, Here, the queries are executed within the Layout Service endpoint and the query results are merged into the JSON data returned in the Layout Service response.
The terms connected and integrated in this context do not have any relation to application modes.
