You can use the tuple() function in tuple.ts to infer tuple types in TypeScript and cut down on the need to repeat yourself. Without tuple(), declaring a constant of a tuple type looks like this:

const daysOfTheWeek: ["sunday", "monday", "tuesday", "wednesday", "thursday", "friday", "saturday"] = 
  ["sunday", "monday", "tuesday", "wednesday", "thursday", "friday", "saturday"];

You can't do this:

const daysOfTheWeek = ["sunday", "monday", "tuesday", "wednesday", "thursday", "friday", "saturday"];

In this gist I would like to describe an idea for GraphQL subscriptions. It was inspired by conversations about subscriptions in the GraphQL slack channel and different GH issues, like #89 and #411.

Conceptual Model

At the moment GraphQL allows 2 types of queries:

• query
• mutation

Reference implementation also adds the third type: subscription. It does not have any semantics yet, so here I would like to propose one possible semantics interpretation and the reasoning behind it.

import {Observable, Disposable} from 'rx';
import {run} from '@cycle/core'
const jsondiffpatch = require('jsondiffpatch').create({
  objectHash: function(obj) {
    return obj.name;
  }
});

function generateCurve(steps){
  var curve = new Float32Array(steps)
