Getting Started

To get started with this project, you likely already have a list of files that you want to parse, something like the following groups.

files/Authors.graphql

query GetAuthors {
  authors {
    ... AuthorFragment
    books {
      ... BookFragment
    }
  }
}

fragment AuthorFragment on Author {
  id
  name
  email
}

files/Books.graphql

query GetBooks {
  books {
    ... BookFragment
  }
}

fragment BookFragment on Book {
  id
  name
  date
  publisher
}

files/Bookstore.graphql

query GetBooksFromBookstore {
  topSellers {
    ... BookFragment
    authors {
      ... AuthorFragment
    }
  }
}

We can then use the graphql-query-parser to extract the executable queries as follows.

import { GraphQLQueryParser } from 'graphql-query-parser';

async function findQueries(directory) {
  return await GraphQLQueryParser.parse(directory);
}

(async function() {
  const results = await findQueries('files/');
  results.forEach((result, idx) => {
      console.log("\nQuery %s: \n%s", idx, result);
  });
});

We would see the following results:

Query 0:
query GetAuthors {
  authors {
    ... AuthorFragment
    books {
      ... BookFragment
    }
  }
}

fragment AuthorFragment on Author {
  id
  name
  email
}

fragment BookFragment on Book {
  id
  name
  date
  publisher
}



Query 1:
query GetBooks {
  books {
    ... BookFragment
  }
}

fragment BookFragment on Book {
  id
  name
  date
  publisher
}



Query 2:
query GetBooksFromBookstore {
  topSellers {
    ... BookFragment
    authors {
      ... AuthorFragment
    }
  }
}

fragment BookFragment on Book {
  id
  name
  date
  publisher
}

fragment AuthorFragment on Author {
  id
  name
  email
}
