The introduction to Reactive Programming you've been missing

(by @andrestaltz)

So you're curious in learning this new thing called (Functional) Reactive Programming (FRP).

Learning it is hard, even harder by the lack of good material. When I started, I tried looking for tutorials. I found only a handful of practical guides, but they just scratched the surface and never tackled the challenge of building the whole architecture around it. Library documentations often don't help when you're trying to understand some function. I mean, honestly, look at this:

Rx.Observable.prototype.flatMapLatest(selector, [thisArg])

Projects each element of an observable sequence into a new sequence of observable sequences by incorporating the element's index and then transforms an observable sequence of observable sequences into an observable sequence producing values only from the most recent observable sequence.

Auth handling in redux.
Before reading:
This is a soft auth check. Auth check should always be done server side, if not, your rest api are not checking correctly for auth.
1. Auth is in the store.
You need to setup constants for AUTH_SET_TOKEN and AUTH_LOGOUT,
then create the action creators authSetToken(token) and authLogout() action creators.
Then setup a reducer that when AUTH_SET_TOKEN is dispatched, sets the internal state to {token: token},
and when logout is dispatched, clears it.
Now setup a utility function isLoggedIn(state) function, that only checks in state.auth.token exists, this is a soft check.

Put the awesome redux-devtools in it's own window so it doesn't obscure or be obscured by your application
// give it a name so it reuses the same window
var win = window.open(null, "redux-devtools", "menubar=no,location=no,resizable=yes,scrollbars=no,status=no");
// reload in case it's reusing the same window with the old content
win.location.reload();
// wait a little bit for it to reload, then render

Created January 4, 2016 02:23 — forked from cmawhorter/proxy.js
Node script to forward all http requests to another server and return the response with an access-control-allow-origin header. Follows redirects.
// Simple proxy/forwarding server for when you don't want to have to add CORS during development.
// Usage: node proxy.js
// Open browser and navigate to http://localhost:9100/[url]
// Example: http://localhost:9100/http://www.google.com
// This is *NOT* for anything outside local development. It has zero error handling among other glaring problems.
// This started as code I grabbed from this SO question: http://stackoverflow.com/a/13472952/670023
