How can I use GraphQL with Gatsby source plugins?

You can use GraphQL with Gatsby by leveraging source plugins to pull in data from various sources. Do you have a specific source in mind?

Yes, I want to use data from a CMS like Contentful.

Great choice! You can use the gatsby-source-contentful plugin. First, install it, then configure it in your gatsby-config.js file with your Contentful space ID and access token.

What kind of queries can I run with GraphQL once I set it up?

Once set up, you can run queries to fetch content types, entries, and assets. For example, you can query for all blog posts or specific fields like titles and slugs.

Can you show me an example of a GraphQL query?

Sure! Here's a simple query to get all blog posts:

query {
  allContentfulBlogPost {
    edges {
      node {
        title
        slug
      }
    }
  }
}
