Learn how to use observables to connect a web audio API to source content from sources like MIDI using RxJS and Angular. Part one of a two-part series.
Right now it's hard to find samples of tests against Angular 2 observable Http code for developers in the current beta. Some of the things you have to watch out for are non-obvious. I expect this will improve vastly over time, but for now hopefully you'll get some working code samples from me to get you going. This post will show you how it’s done.
Now that sonambulent-inauguration, properly known as Angular 2.0.0-beta.0, has dropped, let’s see what the public API is shaping up to be. We’ll review how to create a component from the application bootstrap, using the Http API to fetch a JSON object from HTTP, and see how the template API has changed now that we have to use camelCased property names.
What Angular1 brought, Angular2 takes away – for a good reason. No more Promises in ng2! See how observables make Angular2 a reactive, functional platform. We’ll roll up our sleeves and get something practical done with Angular2’s Http service, and we’ll get some data via the new
Http service – it's quite a bit different than the Angular 1
$http service semantically, but serves the same purpose, but is also more fully featured.
