TypeScriptで相対パスのモジュールをimportしたかった

Last updated at Posted at 2021-12-02

相対パスでモジュールimportしたかったので、ttypescript@zerollup/ts-transform-paths を利用していたけど、typescriptのアップデートで壊れちゃった。

../src/lib/paresArgvと書かなくても、こんなかんじのができてた。

import { parseArgv } from 'lib/parseArgv'

調べてみたら、同じ目にあってる人もいた。

ts-patch

ts-patchを導入すれば、ttypescriptと同等のことをやってくれるっぽい。

対応方法

雑に直した差分を貼っとく
tsconfig.jsonにbaseUrl, paths, pluginsへの設定がない人は入れときましょう。
