Mixins Are Dead. Long Live Composition
When React 0.13 came out, everybody freaked out. The introductory post made it clear that mixins are on their way out: Unfortunately, we will not launch any mixin support for ES6 classes in React. That would defeat the purpose of only using idiomatic JavaScript concepts. There is no standard and universal way to define mixins in JavaScript. In fact, several features to support mixins were dropped

TL;DR: You can check out a React Flux app with authentication implemented in this Github repository Let’s face it. React is the new cool kid on the block. Everybody is working on creating React components beca
React-Router with Flux
react-router provides great route handling with route params and query params. Flux provides a pattern for building React apps, including a pattern from providing data to your components. Here's a straightforward way to make route changes trigger data changes in your components. Note: Code here reflects usage of react-router 0.11.x. It is often the case that we'll need to trigger data changes in a
Setting up minimum single page application
React.jsなどを試そうとするときに、browserify? gulp? grunt? webpack? どれ使えばいいのとか、テストは何を使えばいいのかとかよくわからないというのをたまに聞くので、最低限の設定だけどES6で書けたりautobuildやlivereloadが出来る構成のサンプルを作ってみました。 あと、テストはkarma + mocha + power-assertでchromeでテスト出来るようにしています。 本当はpackage.jsonだけにしたかったのですがkarmaの設定だけは別ファイルになってます...。 テストが必要ない場合は、package.jsonの指定だけで大丈夫です。 https://github.com/koba04/minimum-spa-boilerplate git cloneしてnpm installしてnpm startすればいいだけの
Building The Facebook News Feed With Relay – React Blog
This blog site has been archived. Go to react.dev/blog to see the recent posts. At React.js Conf in January we gave a preview of Relay, a new framework for building data-driven applications in React. In this post, we’ll describe the process of creating a Relay application. This post assumes some familiarity with the concepts of Relay and GraphQL, so if you haven’t already we recommend reading our
React入門用に簡単なアプリケーション作ってみる - yutaponのブログ
React入門系の記事はもう結構出尽くしてる感ありますがせっかくなので私も。 今回はReact v0.13RC2を使って↓のアプリケーションを写経してみます。（Authorは私ではありません） 見ての通り、抵抗の値を計算するアプリケーションです。 Reactで書かれていたり、SVG使ってたり面白いソースですね。 ちなみに抵抗の色の仕様はこのようになってます。 抵抗のカラーコード はじめに React v0.13RC2を使う理由は現時点で最新版ということと、v0.13.0beta1でES6のclass構文が使えるようになったからです。 jsfiddleのソースは1ファイルにまとめて書かれていますが、これを1コンポーネント1ファイルに分割して書いてみます。 React(JSX)のビルドにはBabelが使えるので、前回作ったスケルトンの上に作っていきます。 設計 jsfiddleのJSソースの一

Complex Drag and Drop Lists using React.js
James Burnett I write software for fun and profit. At the moment, I'm doing front-end web development because it is fun. Note: All of the code can be found on GitHub. This article covers creating an HTML5 based drag and drop container that accepts items from compatible containers, has nice animations, and only uses React.js (no Flux based architectures). Others have written on drag and drop with
Streamlining React Elements – React Blog
This blog site has been archived. Go to react.dev/blog to see the recent posts. React v0.13 is right around the corner and so we wanted to discuss some upcoming changes to ReactElement. In particular, we added several warnings to some esoteric use cases of ReactElement. There are no runtime behavior changes for ReactElement - we’re adding these warnings in the hope that we can change some behavior

Flux step by step - Work Life by Atlassian
Facebook has recently presented a new way to compose applications, an application architecture they named Flux. They reported that as modern web applications grow in complexity, this model eases the maintenance and the cognitive load required to develop them. I jumped in excitement (it’s true!) as I immediately saw the beauty of the model. But I wanted to understand it and confirm my intuition and
