babel-cli转换仅具有特定扩展名的文件

Question

目前，我正在使用babel通过npm run script传输我的JSX

{
  "scripts": {
    "prestart": "npm run transpile-views",
    "start": "node ./src",
    "transpile-views": "babel ./src/views --out-dir ./src/views",
    "lint": "eslint src",
  }
}

我使用相同的目录(src/view)作为输入和输出目录，将.jsx文件转到.js。但是，当目录中已经有已传输的文件并再次运行时，npm run transpile-views babel将获取所有.jsx和.js文件。

> my-project@1.0.0 transpile-views ~/Projects/my-project
> babel ./src/views --out-dir ./src/views

srcviews/AuthView.js -> src/views/AuthView.js
src/views/AuthView.jsx -> src/views/AuthView.js
src/views/HomeView.js -> src/views/HomeView.js
src/views/HomeView.jsx -> src/views/HomeView.js
src/views/MainLayout.js -> src/views/MainLayout.js
src/views/MainLayout.jsx -> src/views/MainLayout.js

有办法指定输入文件的扩展名吗？

Babel有选项-x或--扩展，您可以指定：

babel ./src/views -x ".jsx" --out-dir ./src/views
