Rxjs: Some methods are missing when importing just the desired thing

Created on 12 Feb 2016 · 9Comments · Source: ReactiveX/rxjs

For instance,

does-not-work-how-i-had-expected.js

var Observable = require("rxjs/Observable").Observable;
console.log(Observable.of); // undefined

works-how-i-had-expected-1.js

var Observable = require("rxjs").Observable;
console.log(Observable.of); // [Function]

works-how-i-had-expected-2.js

var Observable = require("rxjs/Rx").Observable;
console.log(Observable.of); // [Function]

works-how-i-had-expected-3.js

var o = require("rxjs/Observable").Observable;
console.log(o.of); // undefined
require("rxjs");
console.log(o.of); // [Function] - The method gets mixed into `o`.

It's actually rxjs/add/observable/of now, I think.

I am a little confused over all the different npm distributions of this; perhaps I should be experimenting with npm install @reactivex/rxjs instead?

When RxJS is released; what will be the package name for use with the latest node.js ?

Cheers :)

@kruncher the project is split into modules. when you require('rxjs'), you're importing the most common bits of the library. When you require('rxjs/Observable'), you're importing _just_ the Observable class without any operators.

Batteries-included modules exist (all, core, and DOM), but the operators are also individually exported to enable those whose projects are sensitive to file size. Individual operators can be imported and added to the Observable by importing them from the rxjs/add/ paths.
