For Typescript users, if you get errors with your .gql files, you can add a gql.d.ts file in your sources folder with the following content:

declare module '*.gql' {
  import { DocumentNode } from 'graphql'

  const content: DocumentNode
  export default content

}

declare module '*.graphql' {
  import { DocumentNode } from 'graphql'

  const content: DocumentNode
  export default content
}
