Sourcing from GraphCMS
GraphCMS is a GraphQL native Headless Content Management System (Headless CMS) that lets you programmatically deliver content across platforms. With features like an intuitive schema builder, GraphQL mutations API, and out of the box localization, GraphCMS enables you to rapidly build digital projects with your preferred frameworks and languages.
In this guide you’ll create a Gatsby site capable of querying data from GraphCMS.
This guide assumes the following:
- You have an active GraphCMS account
- You’ve created a new GraphCMS project (preferably using the
All schema and data references in this guide are from the GraphCMS
Blog Starter template.
To begin, let’s create a new Gatsby site using the default starter.
Once finished, navigate inside of the project with
In order to fetch data from your GraphCMS project, you will need to install
You can install this package with:
The last step required before you can query your data is to configure
gatsby-source-graphcms. Inside of
gatsby-config.js, add a new plugin configuration.
We recommend using environment variables with your GraphCMS
endpointvalues. You can learn more about using environment variables with Gatsby in the How-To Guide about environment variables.
Start the Gatsby development environment with
gatsby develop. Once running, you will be able to access the GraphiQL explorer in your browser:
From here, you will be able to browse the generated GraphQL schema of your Gatsby project.
The generated Gatsby types for the GraphCMS project models will all be prefixed accordingly. For example, the
Post model from our GraphCMS project becomes a
GraphCMS_Post type inside of Gatsby. This prefix can be configured.
Query fields also follow a similar naming convention and are prefixed by the same value as types. Gatsby will generate two root query fields per type. For example, for our
Post model Gatsby will generate the following root query fields:
allGraphCmsPostfor querying multiple
graphCmsPostfor querying a single
Using the generated schema, we can begin to write GraphQL queries for Gatsby data. Consider the query below, which will return a full list of all available
Page queries run at build time and can accept GraphQL variables via page context. As the name suggest, they can only be used on pages and not on non-page components.
The resulting data is available via the page props
Static queries also run at build time, but can be used in all components via the
useStaticQuery component. However they do not accept GraphQL variables.

With projects of all sizes transitioning to an API-first approach, creating, enriching, and delivering your content via API to your Gatsby projects is a breeze. Adding a content API in the backend with GraphCMS provides a scalable CMS that you can start using within minutes, and have your project up and running quickly.
