GraphQL is an incredible piece of technology that has captured a lot of mindshare since I first started slinging it in production in 2018. You won’t have to look far back on this (rather inactive) blog to see I have previously championed this technology. After building many a React SPA on top of a hodge podge of untyped JSON REST APIs, I found GraphQL a breath of fresh air. I was truly a GraphQL h
Today we’re excited to announce the release of TypeScript 5.0! This release brings many new features, while aiming to make TypeScript smaller, simpler, and faster. We’ve implemented the new decorators standard, added functionality to better support ESM projects in Node and bundlers, provided new ways for library authors to control generic inference, expanded our JSDoc functionality, simplified con
Easily the biggest question we get asked is something like: How is Remix different from Next.js? It appears we have to answer this question! We'd like to address it directly and without drama. If you're a fan of Remix and want to start tweeting smug reactions to this article, we kindly ask that you drop the smugness before hitting the tweet button 🤗. A rising tide lifts all boats. We've been frie
私たちに最も寄せられる質問は次のようなものです： RemixはNext.jsと一体どう違うの? この記事では私たちはこの質問を答えるべきのようです！私たちはこの議題をストレートに、そして何の感情的な議論なしに言及していきたいと思います。もしあなたがRemixのファンになってくれていて、この記事を見て、今すぐにでもNextよりもRemixの方がすごいぜ 😎、と自慢するようなツイートをしたい気持ちが出てきたとしても、もしできれば、自慢するというような形ではツイートをなるべくしないようにお願いしたいです。私たちは Vercel で働いている方々と Vercel が立ち上がる前から友達です。そして、彼らのやっていることはとても素晴らしく、私たちは彼らを尊敬しています。 ただ、勘違いをしてほしくないのは、私たちはRemixはNext.jsよりも優れている特徴があると思っています。（そうでなければ、

昔はこういうの結構やられてた気がするけど最近あんまり見なくなったのでやってみました。 タイトルは から借用しました。 注意点 プラグイン自体の説明はあまりするつもりはないので、GitHub の README を読むなり使ってみるなりしてみてください。 私は結構頻繁にプラグイン乗り換えるので 2022 春バージョンと思ってください。 私が言うのもあれですが、プラグインはいっぱい入れればいいというものではありません。ひとつひとつを使いこなすのが大事です。多ければそれだけ管理も大変です。 競合があるプラグインは比較して選定しているつもりですが、あくまでも私の趣味の範囲での選定となります。絶対的な指標があってこっちの方が優れているといった判断をしているわけではありません。 私の Neovim の使い方 使い方が違うと参考にならないことが多いため前提としてどういうふうに Neovim を使っているか
Couple of weeks ago when I was publishing The Hidden Cost of URL Design I needed to add SQL syntax highlighting. I headed to PrismJS website trying to remember if it should be added as a plugin or what. I was overwhelmed with the amount of options in the download page so I headed back to my code. I checked the file for PrismJS and at the top of the file, I found a comment containing a URL: /* http
How modern browsers work
Note: For those eager to dive deep into how browsers work, an excellent resource is Browser Engineering by Pavel Panchekha and Chris Harrelson (available at browser.engineering). Please do check it out. This article is an overview of how browsers work. Web developers often treat the browser as a black box that magically transforms HTML, CSS, and JavaScript into interactive web applications. In tru
In our team at Rakuten, we have been using Elm1 in production for almost two years now. This post is about our story, the lessons we learned, and our likes and dislikes.

We were maintaining a medium-size single-page application w
Preliminaries What Is xargs? It's an adapter between text streams and argv arrays, two essential concepts in shell. You pass it flags that specify how to split stdin. Then it generates arguments and invokes processes. Example: $ echo 'alice bob' | xargs -n 1 -- echo hi hi alice hi bob What's happening here? xargs splits the input stream on whitespace, producing 2 arguments, alice and bob. We passe
Rethinking DOM from first principles Browsers are in a very weird place. While WebAssembly has succeeded, even on the server, the client still feels largely the same as it did 10 years ago. Enthusiasts will tell you that accessing native web APIs via WASM is a solved problem, with some minimal JS glue. But the question not asked is why you would want to access the DOM. It's just the only option. S

Parsing SQL - Strumenta
The code for this tutorial is on GitHub: parsing-sql SQL is a language to handle data in a relational database. If you worked with data you have probably worked with SQL. In this article we will talk about parsing SQL. It is in the same league of HTML: maybe you never learned it formally but you kind of know how to use it. That is great because if you know SQL, you know how to handle data. However

I had previously done some work to make sure that <figure> and <figcapti
Did you know that macOS has a secret setting that can make Rust builds faster? It can also make Rust tests faster (sometimes massively so). It probably even has similar effects for other compiled languages such as C, C++, Go, and Swift. It sounds crazy, but read on… The problem Isaac Asimov reportedly said: the most exciting phrase to hear in science… is not “Eureka” but “that’s funny…” I noticed

There is an area of Python that many developers have problems with. This is an area that has seen many different solutions pop up over the years, with many different opinions, wars, and attempts to solve it. Many have complained about the packaging ecosystem and tools making their lives harder. Many beginners are confused about virtual environments. But does it have to be this way? Are the current
How many requests should it take to navigate to another page? In the simplest case, a navigation is resolved in a single request. You click a link, the browser requests the HTML content for the new URL, and then displays it. In practice, a page might also want to display some images, load some client-side JavaScript, load some extra styles, and so on. So there’ll be a bunch of requests. Some will

Should you expect to get 5x performance gains from your webapp by cargo-culting these configuration changes? Probably not. Many of these specific optimizations won't really benefit you unless you are already serving more than 50k req/s to
