Why Patching Globals Is Harmful
Level up your testing skills by learning directly from me! Read more Honestly, I'd never thought I'd be writing about this, but the matter of patching globals turned out to be one of those topics that a lot of engineers seem to misunderstand. Most of us don't do monkey-patching, and even fewer stay around those implementations long enough to witness their impact. All the more reason to talk about
Things you forgot (or never knew) because of React
Published: August 4, 2023 Updated: October 27, 2023 Part 1: an intro about music, defaults, and bubbles Like a lot of people, there was a time when the only music I listened to was whatever was played on my local radio station. (A lot of people over 30 or so, anyway. If this doesn’t sound familiar to you yet, just stick with me for a minute here.) At the time, I was happy with that. It seemed like

core-js/docs/2023-02-14-so-whats-next.md at master · zloirock/core-js
Hi. I am (@zloirock), a full-time open-source developer. I don't like to write long posts, but it seems it is high time to do it. Initially, this post was supposed to be a post about the start of active development of the new major version of core-js and the roadmap (it was moved to the second half), however, due to recent events, it became a really long post about many different things... I'm fuc
Why We're Breaking Up with CSS-in-JS
Hi, I'm Sam — software engineer at Spot and the 2nd most active maintainer of Emotion, a widely-popular CSS-in-JS library for React. This post will delve into what originally attracted me to CSS-in-JS, and why I (along with the rest of the Spot team) have decided to shift away from it. We'll start with an overview of CSS-in-JS and give an overview of its pros & cons. Then, we'll do a deep dive int
The balance has shifted away from SPAs
21 May The balance has shifted away from SPAs Posted May 21, 2022 by Nolan Lawson in Web. Tagged: spas. 24 Comments There’s a feeling in the air. A zeitgeist. SPAs are no longer the cool kids they once were 10 years ago. Hip new frameworks like Astro, Qwik, and Elder.js are touting their MPA capabilities with “0kB JavaScript by default.” Blog posts are making the rounds listing all the challenges
Have Single-Page Apps Ruined the Web? | Transitional Apps with Rich Harris, NYTimes
The backlash to modern front end development is gaining steam, with good reason: single-page apps have ruined the web. Can we rescue it without going backwards? In this talk, Rich Harris presents a way to do just that. Rich Harris is a graphics editor at the New York Times, where he builds JavaScript apps to help explain the news. He is also the creator of Rollup, the JavaScript module bundler, an
Guidelines for choosing a Node.js framework
I often see the question "What’s the best Node.js framework?" crop up on message boards and social media. The replies tend to be full of strong opinions. Some developers will even get into arguments about it. If you’re trying to figure out the right framework for your project, none of this is going to be much help. With lots of frameworks to choose from, and all those strong opinions, it’s easy to
Stay alert
A short while ago, Chrome broke the web by disabling alert(), confirm() and prompt() dialogs from cross-origin iframes. The justification was that "the current UX is confusing, and has previously led to spoofs where sites pretend the message comes from Chrome or a different website"; removing the feature was deemed preferable to fixing the UX. But legitimate uses were affected too. Users of CodePe
Interview with Ryan Dahl, Node.js & Deno creator by Evrone
In an interview with Evrone, Ryan Dahl speaks about the main challenges in Deno, the future of JavaScript and TypeScript, and tells how he would have changed his approach to Node.js if he could travel back in time. We met with Ryan Dahl, the creator of Node.js, to discuss the origins of the platform, its impact on JavaScript, and his thoughts on its future. In the interview he also reflected on hi
`undefined` vs. `null` revisited
Many programming languages have one “non-value” called null. It indicates that a variable does not currently point to an object – for example, when it hasn’t been initialized yet. In contrast, JavaScript has two such non-values: undefined and null. In this blog post, we examine how they differ and how to best use or avoid them. undefined vs. null # Both values are very similar and often used inte
If not SPAs, What?
A few months ago, I wrote an article about how the SPA pattern has failed to simplify web development. The SPA pattern (Single-Page Apps), I tried to define, was about the React model, which also covers, to a large extent, the model of Vue, Angular, and other frontend frameworks. Like any critique, it begs for a prescription and I didn’t give one, other than gesturing toward server-side frameworks
Your SPA doesn’t need a router
So you are building a client-side web app for that next big project and wondering: “Which router should I use?”. Here is the thing: you don’t need any, and you will understand why shortly. What is routing?The first interface for a user to access any website is their browser address bar. Even if your website is visited via a link or from bookmarks, for a user it still goes through the address bar.
Why SolidJS: Do we need another JS UI Library?
It has come to my attention this article is the first some people are hearing of SolidJS. If you want to learn more about Solid, this is NOT where to start. I suggest looking at the github or the links at the bottom of the article. This just details my personal journey and is highly biased. The number of times I've asked myself that over the years is staggering. Even after hitting 2k stars on Gith
About “Zero Dependencies”
There’s a (not really) new trend of describing “zero dependencies” on the Web, especially when it comes to components. This post is just about analyzing the real meaning of “zero dependencies” applied to the Web. Once upon a time …There were few groups of professionals responsible for defining standards for the masses, with at least these goals in mind: ensure great accessibility to be as inclusiv
Crank.js | Introducing Crank
By Brian Kim \u2013 Published April 15, 2020 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 another web framework. There are already so many of them out there and each carries a non-negligible cost in terms of learning it and building an ecosystem t

JavaScripr言語にリアクティビティを実現するフロントエンドフレームワークSvelte 3 - 作者のRich Harris氏に聞く
原文(投稿日：2019/05/06)へのリンク Svelteフロントエンドフレームワークは先頃、Svelte 3をリリースした。Svelte 3では、ユーザーインターフェイスの実装に関連して、エンティティをリンクするインバリアントを宣言的に表現する、新たな方法を導入している。これによって開発者は、パフォーマンスを意識して再レンダリングを実施したり、状態依存の部分を意識的に同期するような処理が不要になる可能性がある。新しいロゴとキャッチフレーズ、Webサイトも用意された。Sapper(Svelteを搭載したNext.jsスタイルのアプリケーションフレームワーク)とSvelte Native (モバイルアプリケーション開発をターゲットとする)は、Svelte 3にアップグレードされている。InfoQは今回、Svelteの開発者であるRich Harris氏にインタビューして、Svelte 3の
Virtual DOM is pure overhead
If you’ve used JavaScript frameworks in the last few years, you’ve probably heard the phrase ‘the virtual DOM is fast’, often said to mean that it’s faster than the real DOM. It’s a surprisingly resilient meme — for example people have asked how Svelte can be fast when it doesn’t use a virtual DOM. It’s time to take a closer look. What is the virtual DOM?In many frameworks, you build an app by cre
