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


`javascript
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(','));
}
`

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

The following will only return top-level fields:
`javascript
const fields = getFieldNames(info, 1);
