How can I use GraphQL variables with Gatsby?

You can use GraphQL variables in Gatsby by defining them in your queries. Would you like a code example?

Yes, please provide a code example.

Sure! Here's a simple example:

query MyQuery($id: String!) {
  myData(id: $id) {
    title
    description
  }
}

You can pass the variable id when you execute the query.

How do I pass the variable when executing the query?

You can pass the variable in the variables option of your query execution. For example:

const { data } = await graphql(`
  query MyQuery($id: String!) {
    myData(id: $id) {
      title
      description
    }
  }
`, { variables: { id: '1' }});
