This is the example that comes with the reagent template converted to use HTML5 based history. This means there are no # in the urls.

I just got this working, so there might be better approaches

The changes are

• use goog.history.Html5history instead of goog.History
• listen to clicks on the page, extract the path from them, and push them onto the history
• listen to history changes, and have secretary do its thing in response

2015-01-29 Unofficial Relay FAQ

Compilation of questions and answers about Relay from React.js Conf.

Disclaimer: I work on Relay at Facebook. Relay is a complex system on which we're iterating aggressively. I'll do my best here to provide accurate, useful answers, but the details are subject to change. I may also be wrong. Feedback and additional questions are welcome.

What is Relay?

Relay is a new framework from Facebook that provides data-fetching functionality for React applications. It was announced at React.js Conf (January 2015).

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.

// ngmin can handle this fine; if not using ngmin, then
// we'd do ['$provide', function($provide) { ... }]
app.config(function($provide) {

   // however, ngmin does not know how to preserve the injected dependencies here!
   $provide.decorator('SomeFactory', function($delegate, $timeout) {

   });

});

// Example

// app.js
document.addEventListener("DOMContentLoaded", function (e) {
  m.route.mode = "hash";
  m.route(document.getElementById("application"), "/", {
    "/": m.resolve("pages.home"),
    "/findus": m.resolve("pages.findus")
  });
});
