This module transforms the GraphQL fields into a string to select fields in MongoDB. The output will be:

'foo.bar.foo = 1'

Usage

const parseFields = require('graphql-mongo-fields')

// my awesome handler
const handler = async (_, args, context, info) => {

    users = await models.User.find({}, parseFields(info))

    return users
}

Development

You can use docker to develop in this project. If you run the bin/run_dev command you'll enter in a Docker container with the node:wheezy image and volumes mounted in /opt/app. Then is just start to coding :)

Don't forget to put the tests in the test/ folder and run typing npm run test.
