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.

npm rank

This gist is updated daily via cron job and lists stats for npm packages:

1. Top 1,000 most depended-upon packages
2. Top 1,000 packages with largest number of dependencies
3. Top 1,000 packages with highest PageRank score

Angular2 + JSPM cheat sheet

First time setup

• install jspm beta: npm install -g jspm@beta
• set up your project: jspm init
• install dependencies: jspm install angular2 reflect-metadata zone.js es6-shim

This will create a jspm_packages folder, and a config.js file.

Open the config.js file - this file manages options for the System.js loader - tweak it as appropriate

Moving to ES6 from CoffeeScript

I fell in love with CoffeeScript a couple of years ago. Javascript has always seemed something of an interesting curiosity to me and I was happy to see the meteoric rise of Node.js, but coming from a background of Python I really preferred a cleaner syntax.

In any fast moving community it is inevitable that things will change, and so today we see a big shift toward ES6, the new version of Javascript. It incorporates a handful of the nicer features from CoffeeScript and is usable today through tools like Babel. Here are some of my thoughts and issues on moving away from CoffeeScript in favor of ES6.

While reading I suggest keeping open a tab to Babel's learning ES6 page. The examples there are great.

Punctuation

Holy punctuation, Batman! Say goodbye to your whitespace and hello to parenthesis, curly braces, and semicolons again. Even with the advanced ES6 syntax you'll find yourself writing a lot more punctuatio

This afternoon I encountered a race condition in an Angular app I'm working on. Essentially my controller was pushing some values to an Array on its scope and something (I wasn't sure what) was asynchronously overriding the Array's contents. The Array was being used by a custom directive- written by someone else- as well as an ngModel and it wasn't clear who was making the change.

I ended up trying something I had not done before and it worked well enough that I thought I'd post it here in case it helped anyone else.

First I enabled The "Async" option in Chrome's "Sources > Call Stack" panel.

Next I set a breakpoint in my controller where I was modifying the Array. When I hit that breakpoint, I ran the following code in my console:

Object.observe(this.theArray, function(changes) {
