配置 ts-loader 后 執行編譯時報錯 TS6142: Module './router' was resolved to 'C:\GitHubWorkspace\webpackPluginDemo\src\router.tsx', but '--jsx' is not set.

這時候 需要在tsconfig.json中添加一條

"jsx": "react"

{
    "compilerOptions": {
      "jsx": "react",
      "target": "es5",
      "sourceMap": true
    },
    "exclude": [
      "node_modules"
    ]
  }
