graphql-list-fields

When implementing a GraphQL server, it can be useful to know the list of fields being queried on a given type. This module takes a GraphQLResolveInfo object and returns a list of fields.

Supported features

• Basic Fields
• Fragments
• Inline Fragments
• @skip and @include directives

• Nested fields into dot.notation

  npm install --save graphql-list-fields
  

Usage

import getFieldNames from 'graphql-list-fields';

// in some resolve function
resolve(parent, args, context, info) {
    const fields = getFieldNames(info);
    return fetch('/someservice/?fields=' + fields.join(','));
}

Depth Limiting

getFieldNames also accepts an optional depth argument, for how many levels deep results should be returned.

The following will only return top-level fields:

const fields = getFieldNames(info, 1);
