Graph Data Layer
===

Description
---
This is an experimental package inspired by facebook's GraphQL.

It provides a practical way of declaring data schemas on the server so that data can be queried in a way that's easy to reason about.

Installation
---
``
npm install graph-data-layer
`

Usage
---

This package has two concerns only:
* Data schemas, providing all info a query can ask for.
* Data queries, providing all info needed to fulfill it.

Both schemas and queries are just JavaScript objects following an specific structure.
We target convention over configuration so we can achieve a simpler syntax for both schemas and queries that are as similar as possible.

#### Setup

`javascript
import initLayer from 'graph-data-layer';

const layer = initLayer();
`

#### Schema

`javascript
const schema = {
resolve() {
return {
names: {
first: 'Lucas',
last: 'Sunsi',
},
occupation: 'Magician',
};
},

firstName(u) {
return user.names.first;
},
hasAwesomeOccupation(u) {
return u.occupation === 'Magician';
},
};

layer.register('ownerUser', schema);
`

$3


`javascript
const query = {
ownerUser: {
firstName: true,
},
};

layer.fulfill(query).then(console.log);
// { firstName: 'Lucas' }
``
