tsconfig.jsonのpaths設定でimport文にエイリアスを使えるようにしたものの、 tscでトランスパイルするとエイリアス形式のパスは変換されない パスの変換のためにtsconfig-pathsなどの追加ライブラリが必要で、ビルドコマンドが冗長になる jestなどはpathsを反映するために追加設定が必要 などで微妙な気持ちになってきたことはありませんか。 一度導入すると利用箇所が結構多くなってきて手動で戻すには大変すぎるし、まあ動いてるからいいか...みたいな。 そんな時のために自動で相対パスに戻せるeslintプラグインを作ってみました。 やめ方 @mkizka/eslint-plugin-relative-import を入れてeslint --fixするだけ。 設定は↓のような感じです。 // eslint.config.js import { relativeImp

In order to use a TypeScript configuration file like eslint.config.ts, users had to specify the unstable_ts_config flag in the command line, e.g. npx eslint --flag unstable_ts_config Copy code to clipboard Following an experi

Over the past few years, Etsy’s Web Platform team has spent a lot of time bringing our frontend code up to date. It was only a year and a half ago that we modernized our Javascript build system in order to enable advanced features, things like arrow functions and classes, that have been added to the language since 2015. And while this upgrade meant that we had futureproofed our codebase and could

IE11で動かしたいコードでelement.prepend()してたら怒ってほしい ライブラリを使っていたらブラウザ間の差異を気にする必要があまりないけど、最近開発しているプロダクトではDOMのAPIを直接触っているので、このメソッドIEにもあるんだっけ、呼んでいいんだっけ、というのをレビューで確認したりしていて苦労していた。 過去にうっかり呼んでしまったメソッドについてはpolyfillが入っていたりして、appendのpolyfillは入ってるけどprependのpolyfillは入っていないためにIE11でエラーになる、ということが起き得る。 ブラウザ間の差異をlintしてくれるグッズとして、eslint-plugin-compatというeslint pluginがあって、fetch使えませんよ、とか発見してエラーとして報告してくれる。 便利なのだけど、たとえばelement.pre
