【2019年版】バックエンドエンジニアが React でモダンなフロントエンド開発を始めるまで - Feedforce Developer Blog
id:daido1976 です。入社してからあっという間に1年が経っていました。 直近3ヶ月ほどプライベートでフロントエンド開発の勉強をしていたのですが、ここ数年で CSS の Grid や React の Hooks が新しく導入されたことなどもあり、少し古いコンテンツだと教材として役立たない1 と感じることが多かったので、本記事では私が実際にやってみた中で 2019年時点で オススメできると判断した教材や学び方を皆さんにご紹介したいと思います。 はじめに やったこと JavaScript MDN の JavaScript の部分を読む & 手を動かす JavaScript Primer を読む YouTube 動画で Promise を学ぶ デバッグ方法を学ぶ React React 公式のチュートリアルを2周する egghead.io の動画で Redux を学ぶ ヘルシンキ大学の
How to better organize your React applications?
I’ve been working on very large web applications for the past few years, starting from ground zero and, with a dozen other developers, making them scale up to now be used by millions of people. And sometimes, if you didn’t start with a good folder structure, it can become difficult to keep your code organized. Nathanael Beisiegel wrote an interesting article where he explains his strategy in the o
React/Redux Tips: Better Way to Handle Loading Flags in Your Reducers
TLDR; Use a separate reducer to store all isFetching flags instead of polluting all of your reducers. So like everyone, you are using React for frontend, Redux for state management, and given that your app is complex enough, then it’s very likely for you to have run into this piece of code: This code would work fine until your app requires a lot more API calls — then half of your reducer code woul
Presentational and Container Components
BismuthUpdate from 2019: I wrote this article a long time ago and my views have since evolved. In particular, I don’t suggest splitting your components like this anymore. If you find it natural in your codebase, this pattern can be handy. But I’ve seen it enforced without any necessity and with almost dogmatic fervor far too many times. The main reason I found it useful was because it let me separ
React NativeのレイアウトエンジンYogaの仕組み [前編] - Adwaysエンジニアブログ
こんにちは、@binaryta です。 先日「React Native OSS ペアプロ会 #3 byFACTBASE」というイベントに参加してきました。 factbase.connpass.com OSSにcommitすることを主眼としていて、React Nativeのissueの問題に解決策を提示したり、解決できそうならPull Requestを送るといった内容です。 このイベントに参加中、レイアウトのバグを直そうとしていた際にYogaを知りYogaに興味を持ちました。 僕は「React Native OSS ペアプロ会」には初回から参加していますが、今後も定期的に開催するみたいなので、興味ある方は是非参加してみてください。 対象 Yogaはクロスプラットフォーム間で共通にレイアウト処理をするべく作られたレイアウトエンジンです。そのためiOSではObjective-C, Android

Best practices for using Typescript with React
By Christopher Diggins There are numerous tools and tutorials to help developers start writing simple React applications with TypeScript. The best practices for using TypeScript in a larger React application are less clear, however. This is especially the case when intergrating with an ecosystem of third party libraries used to address concerns such as: theming, styling, internationalization, logg
Make view 80% width of parent in React Native
I'm creating a form in React Native and would like to make my TextInputs 80% of the screen width. With HTML and ordinary CSS, this would be straightforward: input { display: block; width: 80%; margin: auto; } Except that React Native doesn't support the display property, percentage widths, or auto margins. So what should I do instead? There's some discussion of this problem in React Native's issue
Avoiding Re-Renders in React and optimising MapStateToProps with Reselect.
Avoid unnecessary Re-renders and unnecessary mapStateToProps computations in one go? We will try to answer why and how to create your own Memoized Selectors?First, Let’s start with what is Memoization? In computing, memoization is an optimization technique used primarily to speed up computer programs by storing the results of expensive function calls and returning the cached result when the same i
React’s ⚛️ new Context API – DailyJS – Medium
It’s way more ergonomic, it’s no longer “experimental,” and it’s now a first-class API! OH, AND IT USES A RENDER PROP! NOTE: This is a cross-post from my newsletter.

Unit testing components using React’s new Context APIWith the latest release of React the Context API has finally become a first class citizen. I have just started working with it, and so far it’s been a breeze to work with, but with one small caveat— unit tests. Beyond an official PR in en
Legacy Context – React
Note: The legacy context API will be removed in a future major version. Use the new context API introduced with version 16.3. The legacy API will continue working for all 16.x releases. How To Use Context This section documents a legacy API. See the new API. Suppose you have a structure like: class Button extends React.Component { render() { return ( <button style={{background: this.props.color}}>
How to handle React context in a reliable way.
Context — no pun intended —One-way data flow is one of the most compelling traits of React. It makes your app easier to reason about. You can figure out exactly what props are being passed just by looking at your component. You can even get more out of it adopting the container vs presentational component pattern. But, if you’ve used React for a while, chances are that you’ve found a situation whe
Context in ReactJS Applications - Jack Franklin
February 13, 2017Context in ReactJS ApplicationsThere is a lot of confusion amongst React developers on what context is, and why it exists. It's also a feature that's been hidden in the React documentation in the past and, although it is now documented on the React site I thought a post on its usage and when to use it would be of use. The short answer is that you should very rarely, if ever use co
Update on Async Rendering – React Blog
This blog site has been archived. Go to react.dev/blog to see the recent posts. For over a year, the React team has been working to implement asynchronous rendering. Last month during his talk at JSConf Iceland, Dan unveiled some of the exciting new possibilities async rendering unlocks. Now we’d like to share with you some of the lessons we’ve learned while working on these features, and some rec
