我可以使用哪种匹配器?

  • { test: /\.js$/, loader: 'babel-loader' } - Matches just .js
  • { test: /\.(js|jsx)$/, loader: 'babel-loader' } - Matches both js and jsx
  • Generally put it's just a JavaScript regex so standard tricks apply
  • { test: /\.js$/, loader: 'babel-loader' } - 只匹配 .js
  • { test: /\.(js|jsx)$/, loader: 'babel-loader' } - 匹配 js 和 jsx
  • 一般来说它就是一段 JavaScript 的正则,所以按照标准来即可
