Graphql-js: A way to validate objects against schema?

Created on 7 Nov 2016 · 4Comments · Source: graphql/graphql-js

I would like to be able to use graphQL schemas to validate my objects against the types defined in graphql schemas like so:

'use strict'
const { expect } = require('chai')
const { buildSchema } = require('graphql/utilities')

describe('validating objects with graphql', function() {
  it('returns true or false given an object, type name and a schema', function () {
    const schema = buildSchema(`
      type User {
        id: String
        name: String
      }
    `)

    let valid = validate({ name: 123}, 'User', schema)
    expect(valid).to.be(false)

    let valid = validate({ name: 'swist'}, 'User', schema)
    expect(valid).to.be(true)
  })
})

Is this possible? Or am I misunderstanding something fundamental about the spec?
I've had small dig around the library and the docs and it doesn't seem like graphql-js provides something to this effect.

Essentially it would allow people who want to use graphql to gradually write out schemas for their models.

A pointer whether it is desirable and possible to implement validate above would be much appreciated!
