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.

A lot of people mentioned other immutable JS libraries after reading my post. I thought it would be good to make a list of available ones.

There are two types of immutable libraries: simple helpers for copying JavaScript objects, and actual persistent data structure implementations. My post generally analyzed the tradeoffs between both kinds of libraries and everything applies to the below libraries in either category.

Libraries are sorted by github popularity.

Persistent Data Structures w/structural sharing

Markdown License badges

Collection of License badges for your Project's README file.
This list includes the most common open source and open data licenses.
Easily copy and paste the code under the badges into your Markdown files.

Notes

The badges do not fully replace the license informations for your projects, they are only emblems for the README, that the user can see the License at first glance.

	* Code from:
	* https://github.com/expressjs/express/pull/2809
	*
	* Target Express version: { "express": "^4.14.0 <5.0.0" }
	*
	* This monkey patch allows to return Promises from middleware and route handlers, rejections will be handled automaticaly.
	*
	* Please note:
	* If you return something from `(...) -> void` callbacks - you shoot your own leg.
