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.

// Turns out this was not too difficult.
// By using the event loop as a global mail box ordering is even guaranteed for messages between only two actors.
// TODO would like to try and put one actor in a web worker to get some real parallism
// TODO would like to handle errors and have the concept of a deceased actor while a reference to an actor still exists. Probably involves creating an actor system like in Scala. Eurgh.

var actor = {
  send: function(message) {
    var self = this;
    console.log("sending to:", self);
    setTimeout(function(){

Factory Loader

This is a tiny webpack loader that invokes a given module with another as an argument.

What's that useful for? Dependency Injection! Maybe this is how we can solve the VDOM fragmentation issue.

Example

Here's a library-agnostic VDOM component. Notice that it doesn't import react/preact/inferno/whatever - instead, it takes the VDOM library as an argument.

A vision for data interchange in Elm

How do you send information between clients and servers? What format should that information be in? What happens when the server changes the format, but the client has not been updated yet? What happens when the server changes the format, but the database cannot be updated?

These are difficult questions. It is not just about picking a format, but rather picking a format that can evolve as your application evolves.

Literature Review

By now there are many approaches to communicating between client and server. These approaches tend to be known within specific companies and language communities, but the techniques do not cross borders. I will outline JSON, ProtoBuf, and GraphQL here so we can learn from them all.
