Creating backpressured data sources is the relatively easier task when dealing with backpressure in general because the library already offers static methods on Observable that handle backpressure for the developer. We can distinguish two kinds of factory methods: cold "generators" that ei...

Basic HTTP calls don't provide code-reusability, however. And they can get confused with all the other features you're trying to implement. For those reasons, it's common to implement an API wrapper. Foo = { identify: function(input){ return Http.get('http://foo.net/api/identify/' + input...

After creating an API wrapper, it's likely that you may want to create an Atmosphere package to redistribute it and share it between applications. The files of your package will probably look something like this. packages/foo-api-wrapper/package.js packages/foo-api-wrapper/readme.md packages/foo-...

At this point, you're still building your package, so you'll need to add the package to your application: meteor add myaccount:foo And eventually publish it to Atmosphere: meteor publish myaccount:foo

Now that we have all those pieces put together, you should now be able to make calls like the following from within your app: Foo.identify('John'); Foo.record_action_on_item('view', "HackerNews'); Obviously you'll want to adjust function names, arguments, urls, and the like, to create the ...

As well as being able to create an array by filtering out nil from the transformed elements of a sequence, there is also a version of flatMap(_:) that expects the transformation closure to return a sequence S. extension SequenceType { public func flatMap<S : SequenceType>(transform: (Sel...

A class constructor must have the same name as its class. Let's create a constructor for a class Person: class Person { String name; String gender; int age; Person(this.name, this.gender, this.age); } The example above is a simpler, better way of defining the constructor than the...

Dart functions may also be declared anonymously or nested. For example, to create a nested function, just open a new function block within an existing function block void outerFunction() { bool innerFunction() { /// Does stuff } } The function innerFunction may now be us...
