Leaving Callback Hell with Promises and ES7 async/await

Cross post from my employer's development blog: http://rootinc.github.io/2016/01/14/callback-hell/

Slides and code from my talk for the Toledo Web Proffessionals on 1/13/2016. It was a quick overview of how Promises in ES6 and async/await in ES7 can allow for much cleaner JavaScript coding.

IE Caches a Lot

Cross post from my employer's development blog: http://rootinc.github.io/2016/03/09/ie-caches/

In developing a page, I decided to do things a bit differently on the server. By doing an explicit check on the HTTP request headers, I can detect server-side if a request to the server is coming via XHR (Ajax) or a standard page load. I can then serve different content based on the request type. So, I can use the same URL for retrieving the initial HTML page and the raw JSON data associated with that page. Express makes this pretty easy:
if (req.xhr){ return res.json(await this.usersData()); } else { return res.view('users', await this.usersData()); }
I’m not sure if it’s technically more RESTful than having separate URL routes for data and HTML, but it felt like it made sense. The URL is referring to the same data, and based on a header, I want to determine how it is represented, but the data doesn’t change so why should the URL? This also makes it possible to d…

Quick Deepstream.io Setup Using JSPM

Cross post from my employer's development blog: http://rootinc.github.io/2016/02/12/deepstream-jspm/
Want to use JSPM rather than Bower for running the Deepstream.io example? Follow these steps. This is basically a duplicate of the [Getting Started tutorial][tutorial] on the [Deepstream.io website][website] but using a really simple JSPM setup. This is a very crude guide where I list everything I had to do to get things running.

Create an empty project folder npm install deepstream.io Copy server code verbatim from the Getting Started guide jspm install npm:deepstream.io-client-js Hit enter for all the prompts from JSPM

We’re going to modify the client side code a little bit. We have native support for ES6 compiling with JSPM/Babel so we can import the Deepstream client directly:

import deepstream from 'deepstream.io-client-js'; let ds = deepstream( 'localhost:6020' ).login();

let record = ds.record.getRecord( 'someUser' );

let input = document.querySelector( 'inp…
