This article has been given a more permanent home on my blog. Also, since it was first written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.
Promises are a software abstraction that makes working with asynchronous operations much more pleasant. In the most basic definition, your code will move from continuation-passing style:
getTweetsFor("domenic", function (err, results) {
// the rest of your code goes here.

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.
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.

I work at Grammarly. We like React and happily use it in our applications. However, sometimes something goes wrong and bugs creep into the code. Here comes testing. It helps make us confident about the quality of our code.
