## Keep it Simple
Pedro Nauck ([pedronauck](https://github.com/pedronauck)) delivered an impeccably illustrated deck at Brazil's _Front in Floripa_ conference. Watch him talk about how to keep delivering value as your app scales, by keeping your development process simple.
Murilo Pereira ([mpereira](https://github.com/mpereira)) tussles with the topic of complexity in this blog post about [coping with scaling up](http://www.techsonian.net/2014/09/from-backbone-to-react-our-experience-scaling-a-web-application/), where he describes how his team used React to make possible the “nearly impossible.”
I ([steveluscher](https://github.com/steveluscher)) spoke at Manning Publications' “Powered By JavaScript” Strangeloop pre-conf in St. Louis. There, I proposed a new notation to talk about development complexity – Big-Coffee Notation ☕(n) – and spoke about the features of React that help keep our Big-Coffee from going quadratic, as our user interfaces get more complex.
James Pearce ([jamesgpearce](https://github.com/jamesgpearce)) carried Big-Coffee all the way to Raleigh, NC. At the _All Things Open_ conference, he spoke about some of the design decisions that went into React, particularly those that lend themselves to simpler, more reliable code.
## All About Isomorphism
Michael Ridgway ([mridgway](https://github.com/mridgway)) shows us how Yahoo! (who recently [moved Yahoo! Mail to React](http://www.slideshare.net/rmsguhan/react-meetup-mailonreact)) renders their React+Flux application, server-side.
Péter Márton ([hekike](https://github.com/hekike)) helps us brew a cold one (literally) using an application that's server-client [isomorphic and indexable](http://blog.risingstack.com/from-angularjs-to-react-the-isomorphic-way/). Demo and sample code included – cold ones sold separately.
And, lest you think that client-server isomorphism exists in pursuit of crawalable, indexable HTML alone, watch as Nate Hunzaker ([nhunzaker](https://github.com/nhunzaker)) [server renders data visualizations as SVG](http://viget.com/extend/visualization-is-for-sharing-using-react-for-portable-data-visualization) with React.
## React Router Mows the Lawn
Ryan Florence ([rpflorence](https://github.com/rpflorence])) and Michael Jackson ([mjackson](https://github.com/mjackson)) unveiled a new API for [React Router](https://github.com/rackt/react-router) that solves some of its user's problems by eliminating the problems themselves. Read all about what React Router learned from its community of users, and how they've [rolled your ideas into their latest release](https://github.com/rackt/react-router/wiki/Announcements).
## React in Practice
Jonathan Beebe ([somethingkindawierd](https://github.com/somethingkindawierd)) spoke about how he uses React to build tools that deliver hope to those trying to make the best of a bad situation. Watch his talk from this year's _Nodevember_ conference in Nashville
If you take a peek under the covers, you'll find that React powers [Carousel](https://blog.carousel.com/2014/11/introducing-carousel-for-web-ipad-and-android-tablet/), Dropbox's new photo and video gallery app.
We enjoyed a cinematic/narrative experience with this React-powered, interactive story by British author William Boyd. Dive into “[The Vanishing Game](https://thevanishinggame.wellstoried.com)” and see for yourself.
## Be Kind, Rewind
Spend the next 60 seconds watching Daniel Woelfel ([dwwoelfel](https://github.com/dwwoelfel)) serialize a React app's state as a string, then deserialize it to produce a working UI. Read about how he uses this technique to [reproduce bugs](http://blog.circleci.com/local-state-global-concerns/) reported to him by his users.
## Community Components
Tom Chen ([tomchentw](https://github.com/tomchentw)) brings us a [react-google-maps](https://tomchentw.github.io/react-google-maps/) component, and a way to syntax highlight source code using Prism and the [react-prism](https://tomchentw.github.io/react-prism/) component, for good measure.
Jed Watson ([jedwatson](https://github.com/JedWatson)) helps you manage touch, tap, and press events using the [react-tappable](https://github.com/JedWatson/react-tappable) component.
To find these, and more community-built components, consult the [React Components](http://react-components.com/) and [React Rocks](http://react.rocks) component directories. React Rocks recently exceeded one-hundred listed components and counting. See one missing? Add the keyword `react-component` to your `package.json` to get listed on React Components, and [submit a link to React Rocks](https://docs.google.com/forms/d/1TpnwJmLcmmGj-_TI68upu_bKBViYeiKx7Aj9uKmV6wY/viewform).
## Waiter, There's a CSS In My JavaScript
The internet is abuzz with talk of styling React components using JavaScript instead of CSS. Christopher Chedeau ([vjeux](https://github.com/vjeux)) talks about some of the [fundamental style management challenges](https://speakerdeck.com/vjeux/react-css-in-js) we grapple with, at Facebook scale. A number of implementations of JavaScript centric style management solutions have appeared in the wild, including the React-focused [react-style](https://github.com/js-next/react-style).
## Test Isolation
Yahoo! shows us how they make use of `iframe` elements to [unit test React components in isolation](http://yahooeng.tumblr.com/post/102274727496/to-testutil-or-not-to-testutil).
## You've Got The Hang of Flux, Now Let's Flow
Facebook Open Source released [Flow](https://code.facebook.com/posts/1505962329687926/flow-a-new-static-type-checker-for-javascript/) this month – a static type checker for JavaScript. Naturally, Flow supports JSX, and you can use it to [type check React applications](https://code.facebook.com/posts/1505962329687926/flow-a-new-static-type-checker-for-javascript/#compatibility). There's never been a better reason to start making use of `propTypes` in your component specifications!
## Countdown to React.js Conf 2014
We're counting down the days until [React.js Conf](http://conf.reactjs.com) at Facebook's headquarters in Menlo Park, California, on January 28th & 29th, 2015.
