publint
What is publint publint lints npm packages to ensure widest compatibility across environments, such as Vite, Webpack, Rollup, Node.js, etc. A full list of lint rules can be found at the rules page. How it works When linting an npm package, the site downloads the tarball from the npm registry, and runs publint against it in a web worker. For larger packages, it may take a while to download and lint
Deep JavaScript: Theory and techniques
About the book This book dives deeply into JavaScript: It teaches practical techniques for using the language better. It teaches how the language works and why. What it teaches is firmly grounded in the ECMAScript specification (which the book explains and refers to). It covers only the language (ignoring platform-specific features such as browser APIs) but not exhaustively. Instead, it focuses on
HTML Over The Wire | Hotwire
Hotwire is an alternative approach to building modern web applications without using much JavaScript by sending HTML instead of JSON over the wire. This makes for fast first-load pages, keeps template rendering on the server, and allows for a simpler, more productive development experience in any programming language, without sacrificing any of the speed or responsiveness associated with a traditi
Abortable fetch | Blog | Chrome for Developers
The original GitHub issue for "Aborting a fetch" was opened in 2015. Now, if I take 2015 away from 2017 (the current year), I get 2. This demonstrates a bug in maths, because 2015 was in fact "forever" ago. 2015 was when we first started exploring aborting ongoing fetches, and after 780 GitHub comments, a couple of false starts, and 5 pull requests, we finally have abortable fetch landing in brows

2017 JavaScript Rising Stars
As we did last year, it's time to look back at the JavaScript landscape in 2017. Let's see by the numbers which projects got traction in 2017 by comparing the numbers of stars added on GitHub over the last 12 months, and find out who are 2017's JavaScript Rising Stars. The following graphs compare the number of stars added on GitHub over the last 12 months. We analyzed projects coming from Best of
webpackとRollup：似て非なるもの | POSTD
先日、Facebookは 膨大なプルリクエスト をReactにマージして、既存のビルドシステムを Rollup ベースのシステムに移行しました。 その結果 、 何人もの人々 から「なぜwebpackではなくRollupを選んだのか」という質問が寄せられました。 これは、もっともな疑問でしょう。 webpack は、近年JavaScriptコミュニティで最も評価されているツールの1つです。毎月のダウンロード数は何百万件にもおよび、何万個ものウェブサイトやアプリケーションに使用されています。巨大なエコシステムがあり、コントリビュータも多くいます。さらにオープンソースプロジェクトとしては珍しく、 かなりの寄付金 が集まっています。 それに比べるとRollupは小規模です。しかしReact以外にも、Vue、Ember、Preact、D3、Three.js、Momentなど、数々の有名なライブラリに
イマドキのJavaScriptの書き方2018
PySpa統合思念体です。これからJavaScriptを覚えるなら、「この書き方はもう覚えなくていい」（よりよい代替がある）というものを集めてみました。 ES6以降の難しさは、旧来の書き方にプラスが増えただけではなく、大量の「旧来の書き方は間違いを誘発しやすいから非推奨」というものを作り出した点にあります。5年前、10年前の本やウェブがあまり役に立たちません。なお、書き方が複数あるものは、好き嫌いは当然あると思いますが、あえて過激に1つに絞っているところもあります。なお、これはこれから新規に学ぶ人が、過去のドキュメントやコードを見た時に古い情報を選別するためのまとめです。残念ながら、今時の書き方のみで構成された書籍などが存在しないからです。 たぶん明示的に書いていても読み飛ばす人はいると思いますが、すでに書いている人向けではありません。これから書くコードをこのスタイルにしていくのは別にいい

The Anatomy of a Thousand Typefaces
Even years after Avatar’s release, there’s one thing Ryan Gosling just can’t get over: the choice of the movie’s logo font “Papyrus”. In the parody produced by Saturday Night Live, the designer of the logo opens the font menu, browses the fonts one by one, and randomly decides to go with “Papyrus”. “Papyrus” by Saturday Night LiveThe seemingly mindless choice of a font is a general problem with fo
