make it accept a url of graphQL endpoint as well as a file

[capaj]

now I have to make the IntrospectionQuery myself, save the file as json and then run gql2flow command.

It would be really convenient if I could just do something like:

gql2flow https://graphql-explorer.githubapp.com/graphql/proxy

@capaj try using apollo-codegen for this, you can combine it with this package and you'll get what you want :)

I really like this idea, I'll see what I can do!

If it's of any help, here's a script I'm currently using (I think I just copied it from Relay):

const fetch = require('node-fetch')
const fs = require('fs')
const {
  buildClientSchema,
  introspectionQuery,
  printSchema,
} = require('graphql/utilities')
const path = require('path')
const schemaPath = path.join(__dirname, '..', 'schema')

const SERVER = 'http://localhost:3000/graphql'

fetch(`${SERVER}`, {
  method: 'POST',
  headers: {
    'Accept': 'application/json',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({'query': introspectionQuery}),
}).then(res => res.json()).then(schemaJSON => {
  fs.writeFileSync(
    `${schemaPath}.json`,
    JSON.stringify(schemaJSON, null, 2)
  )

  // Save user readable type system shorthand of schema
  const graphQLSchema = buildClientSchema(schemaJSON.data)
  fs.writeFileSync(
    `${schemaPath}.graphql`,
    printSchema(graphQLSchema)
  )
})

And then run from npm/yarn:

"update-schema": "babel-node ./scripts/updateSchema.js && gql2flow -o schema.flow.js schema.json"

Any chance of this getting added to the core?

Added this in the latest version (0.4.x), please do try it out. No support for auth headers right now but can add if there is need.
