## Keep it Simple {#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 {#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.

<script async class="speakerdeck-embed" data-id="87ecaa3048750132f42542ffc18c6fcf" data-ratio="1.77777777777778" src="//speakerdeck.com/assets/embed.js"></script>

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 {#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 {#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

<iframe width="650" height="315" src="//www.youtube-nocookie.com/embed/uZgAq1CZ1N8" frameborder="0" allowfullscreen></iframe>

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 {#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 {#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 {#waiter-theres-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 {#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 {#youve-got-the-hang-of-flux-now-lets-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 {#countdown-to-reactjs-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. Thank you, to everyone who responded to the Call for Presenters. Mark the dates; tickets go on sale in three waves: at noon PST on November 28th, December 5th, and December 12th, 2014.
