概要

表題のとおりのミスをやらかしたのでメモ。
tsconfigの設定をいじっている間におかしくなってしまったらしい。

解決法

node_modulesをincludeから外したら解決した。
そもそもnode_modulesをトランスパイルしようとしているのがおかしい（参考: tsconfigオプション)。

tsconfig.json

{
  "compilerOptions": {
    "target": "es5",
    "lib": [
      "dom",
      "dom.iterable",
      "esnext"
    ],
    "allowJs": true,
    "skipLibCheck": true,
    "esModuleInterop": true,
    "allowSyntheticDefaultImports": true,
    "strict": true,
    "forceConsistentCasingInFileNames": true,
    "noFallthroughCasesInSwitch": true,
    "module": "esnext",
    "moduleResolution": "node",
    "resolveJsonModule": true,
    "isolatedModules": true,
    "noEmit": true,
    "jsx": "react-jsx",
    "paths": {
      "@/*": ["../../client/src/*"]
    }
  },
  "include": [
    ".storybook",
    "../../client/src",
    "./stories"
-    ,"./node_modules"
  ]
}

エラー

Reactでstorybook起動時にJavaScript heap out of memoryが出たけど解決した話とは原因が別だったもよう。
