Introducing Turbopack: Rust-based successor to Webpack – Vercel
Vercel's mission is to provide the speed and reliability innovators need to create at the moment of inspiration. Last year, we focused on speeding up the way Next.js bundles your apps. Each time we moved from a JavaScript-based tool to a Rust-based one, we saw enormous improvements. We migrated away from Babel, which resulted in 17x faster transpilation. We replaced Terser, which resulted in 6x fa
Common mistakes with React Testing Library
Common mistakes with React Testing LibraryMay 4th, 2020 — 15 min read Hi there 👋 I created React Testing Library because I wasn't satisfied with the testing landscape at the time. It expanded to DOM Testing Library and now we have Testing Library implementations (wrappers) for every popular JavaScript framework and testing tool that targets the DOM (and even some that don't). As time has gone on,
Getting Started - Electron Forge
Quickly scaffold an Electron project with a full build pipeline Electron Forge is an all-in-one tool for packaging and distributing Electron applications. It combines many single-purpose packages to create a full build pipeline that works out of the box, complete with code signing, installers, and artifact publishing. For advanced workflows, custom build logic can be added in the Forge lifecycle t
Node.jsのアプリケーションデバッグ・改善方法をおさらいする - hiroppy's site
ステップ実行 --debugと--debug-brkは Node8 の時点ですでに非推奨なので、使わないでください。 デバッグ方法 コンソール Chrome devtools または、VSCode のような IDE に任せる 今回は、エディタ依存の話は特にしないです。 共通的な手順 基本的には、debugger を止めたい場所に置いていくことになります。 例として、以下のコードで説明していきます。 "use strict"; const { readFile } = require("fs"); const { promisify } = require("util"); const readFileAsync = promisify(readFile); (async () => { const data = await readFileAsync("hello.txt", "utf8"
GitHub - elsewhencode/project-guidelines: A set of best practices for JavaScript projects
There are a set of rules to keep in mind: Perform work in a feature branch. Why: Because this way all work is done in isolation on a dedicated branch rather than the main branch. It allows you to submit multiple pull requests without confusion. You can iterate without polluting the master branch with potentially unstable, unfinished code. read more... Branch out from develop Why: This way, you can

JavaScript API Hall of Shame
In this day and age it is pretty common to design a large-scale web application as a collection of modular and reusable components. These components need to have a reasonable set of APIs (application programming interfaces) which deliver against the stipulated engineering criteria. In addition this API set needs to retain ease of use. The success of a module is thus reflected in the way it is bein
Shibu's Diary: JavaScriptのメモリリークを10倍速で発見する
渋日記@shibu.jp 渋川よしきの日記です。ソフトウェア開発とか、ライフハックを中心に記事を書いていきます。 メモリリーク。一言でプログラマを死に追いやる恐怖の言葉。C/C++の世界ではmallocしたのにfreeしないとかのケアレスミスでよく起きていた問題です。その後、ガベージコレクタが掃除してくれるプログラミング言語が増え、一部の言語で循環参照に気をつけるぐらいであまり気にしなくても良い的な風潮になっています。 というものの、そうとも言ってられなくない状況も増えてきています。クラウドのスケールアウトブームも一段落というかコモディティ化し、go言語で再び性能向上方面に関心が寄せられたり、日本でErlangの勉強会が満席になったり、スケールアウトから再びスケールアップ方面に話題が移りつつあるのを感じます。長時間稼働のサーバで、スケールアップしてさらに数多くのリクエストを大量に受けるよう
Lesser-Known JavaScript Debugging Techniques
After I prototype an app I'm building, my time is split between the editor and the browser with the console open. I try to debug as I go to avoid creating a complete mess. Moreover, when I get a bug report for a production app the first thing that I do is try to debug using Chrome devtools, and I usually find the bug without touching my editor. To be effective at that, I had to learn a great deal
An Introduction to Source Maps [Article] | Treehouse Blog
One of the easiest performance wins you can gain for your website is to combine and compress your JavaScript and CSS files. But what happens when you need to debug the code within those compressed files? It can be a nightmare. Fear not however, there is a solution on the horizon and it goes by the name of source maps. A source map provides a way of mapping code within a compressed file back to it’
