楽にLintを導入したかっただけなのに

$ npx gts init

何も考えずOverwriteﾎﾟﾁｰ

エラーの山が襲来

AoT buildができない！

多すぎて一部抜粋。

これとか
addEventListener(element: HTMLElement, eventName: string, handler: Function): Function;

これとか
src/main.ts:12:17 - error TS2584: Cannot find name 'console'. Do you need to change your target library? Try changing the `lib` compiler option to include 'dom'.

⇒ gtsでtsconfig.jsonが上書きしてしまったことが原因。

解決法

tsconfig.jsonのtargetやlibを戻せば解決した。

tsconfig.json
