Excellence in Software

After spending the past couple of posts talking about how we integrate and why, let’s get back to the basic operators of the Reactive Extensions for JavaScript.  This time, we’ll cover conditional logic that we can do with RxJS (which also applies to Rx.NET as well).  With traditional LINQ, we have the Where operator which allows us to filter operations, but it doesn’t allow us to do one operation or another easily.  Instead, the Reactive Extensions team has included two operators...

In the previous post, I covered a bit about how we’ve integrated the Dojo Toolkit into the Reactive Extensions for JavaScript (RxJS) where we can leverage Dojo’s eventing and AJAX programming model.  Following onto that post, I wanted to move onto a different framework and show how we integrated it into RxJS.  This time, it’s MooTools up to the plate. Now the question comes, why then if the given framework works as well as it does, why would we care to integrate it into RxJS?  Wha... [read more]

Recently in some of the comments I’ve received (keep them coming BTW), I get questions about taking existing APIs and moving them towards using the Reactive Extensions for JavaScript (RxJS).  How can we get away from constant callback hell and move towards composable asynchronous and event-based blocks instead?  In this post, I’m going to walk through how we wrapped the Dojo Toolkit APIs to provide both event handling and AJAX functionality. Before we get started, let’s get caught up t... [read more]

There has been a lot of movement around the Reactive Extensions lately and I thought I’d round them up for you in an easy to find location.  Between the new release and various interviews, there’s a bit to cover. New Release Last Friday there was a release of the Reactive Extensions for both .NET and JavaScript for which the release notes can be found here.  On the .NET side of the house, the biggest addition is the addition of IQbservable, which is short of IQueryableObservable. ...

In the previous post, I talked a little bit about asynchronous method chaining and extending jQuery in a fluent style to fetch tweets from Twitter and append them to a given element.  This time I want to expand upon that post, instead of taking only one tweet, I want to take one hundred of them and then cycle through each of them at a given interval.  In order to do that, I must make use of something that I alluded to in earlier posts, and that is a custom scheduler. Before we get star... [read more]

In the previous couple of posts, I’ve talked about asynchronous method chaining and creating custom schedulers so I can repeatedly hit a data source for its data, transform it and then display the results.  Instead of just setting a custom interval between the results and querying the system, so this time, I want to stick a timer where I can monitor the time between queries.  Before we get started, let’s get caught up to where we are today: Introduction Creating Observables Creatin...

Recently, there was a blog post by Dustin Diaz about method chaining over asynchronous operations.  This topic, of course is near and dear to my heart as it strikes the exact chord of what the Reactive Extensions for JavaScript (RxJS) is trying to solve.  The ability for us to take asynchronous operations and events and treat them as push collections, we are able to then compose functions together as if they were normal pull collections like arrays.  In this post, I’ll walk throug...

We’ve covered a lot of ground so far in this series including a lot of the combinators as well as the integration into third party libraries.  Most of these examples have been from a green field mindset where we have an idea and then walk through how you would accomplish it using the Reactive Extensions for JavaScript (RxJS).  This time, we’re going to take a game that’s already been written and take parts of it and migrate it to use RxJS. Before we get started, let’s get caught up to ... [read more]
