Rewriting Recoil from scratch
Recoil is a slick new React library written by some people at Facebook that work on a tool called "Comparison View." It came about because of ergonomics and performance issues with context and useState. It's a very clever library, and almost everyone will find a use for it - check out this explainer video if you want to learn more. At first I was really taken aback by the talk of graph theory and

Crank.js | Introducing Crank
By Brian Kim – April 15, 2020 A deep dive into why Crank.js was created, exploring the limitations of React's Suspense API and the philosophy behind using generators and async functions for components. After months of development, I’m happy to introduce Crank.js, a new framework for creating JSX-driven components with functions, promises and generators. And I know what you’re thinking: oh no, not

Build your own React
We are going to rewrite React from scratch. Step by step. Following the architecture from the real React code but without all the optimizations and non-essential features. If you’ve read any of my previous “build your own React” posts, the difference is that this post is based on React 16.8, so we can now use hooks and drop all the code related to classes. You can find the history with the old blo
I created the exact same app in React and Vue. Here are the differences. [2019 Edition]
Having used Vue at work, I had a fairly solid understanding of it. I had, however, been curious to know what the grass was like on the other side of the fence — the grass in this scenario being React. Note: there is a new version of this article that can be found here: https://sunilsandhu.com/posts/i-created-the-exact-same-app-in-react-and-vue-2020-edition I’d read the React docs and watched a few

Handling API request race conditions in React
Many blog articles talk about loading api/async data in React apps, with componentDidMount, useEffect, Redux, Apollo… Yet, all those articles are generally optimistic, and never mention something important to consider: race conditions could happen, and your UI may end up in an inconsistent state. An image is worth a thousand words: You search for Macron, then change your mind and search for Trump,
Algebraic Effects for the Rest of Us — overreacted
Algebraic Effects for the Rest of UsJuly 21, 2019 Have you heard about algebraic effects? My first attempts to figure out what they are or why I should care about them were unsuccessful. I found a few pdfs but they only confused me more. (There’s something about academic pdfs that makes me sleepy.) But my colleague Sebastian kept referring to them as a mental model for some things we do inside of
Folding the DOM • Josh W. Comeau
Filed underReactoninMay 19th, 2019.May 2019.Last updatedoninSeptember 13th, 2024.Sep 2024. IntroductionIn my day-to-day life as a front-end developer, I generally treat CSS as a collection of 2D layers. Other than reordering them using z-index, I don't often move things in 3D space. And yet, for years now, browsers have bundled in a surprisingly capable 3D CSS engine! Someone even built an experim

Why Do React Hooks Rely on Call Order?December 13, 2018 At React Conf 2018, the React team presented the Hooks proposal. If you’d like to understand what Hooks are and what problems they solve, check out our talks introducing them and my follow-up article addressing common misconceptions. Chances are you won’t like Hooks at first: They’re like a music record that grows on you only after a few good
React for the Angular Dev – Austin – Medium
PrefaceAngular and React have dominated the landscape of JavaScript frameworks for some time now. Chances are you probably picked one that suited your needs best and probably stuck with it; after all humans don’t really like change. This article is for those who have been working in Angular and haven’t had a chance to venture into other frameworks and try them out. Before we get started, I want to
Re-ducksパターン：React + Redux のディレクトリ構成ベストプラクティス
Re-ducks というディレクトリ構成のベストプラクティスについてまとめる。Re-ducksパターンを使うことで、React + Redux を用いた開発がよりメンテナンスしやすいものになる。 Ducks パターン 名前からもわかるように、Re-ducks は Ducks というパターンをベースにしている。 erikras/ducks-modular-redux Ducks パターンが解決すること： actionType、action、reducerが散らばっててつらい 結局のところ actionType、action、reducer は密結合なので、ducksパターンではこれら3つを1つのファイルにまとめる。 // widget.js // Actions const LOAD = 'my-app/widgets/LOAD'; const CREATE = 'my-app/widget
