无限Webpack监视循环 - 如何忽略对.js文件的更改等

标签: javascript node.js typescript webpack

使用ts-loader的webpack -w命令处于无限循环中。我猜它是因为webpack -w看到.js文件的更改,因此导致循环

  

webpack -w => ts transpile => .js changes => webpack -w

有没有人见过这个?告诉webpack -w忽略.js文件是最好的办法吗?我怎么能这样做?

这是我的webpack.config.js文件:

module.exports = {

  entry: ['babel-polyfill', './lib/index.ts'],

  output: {
    path: path.resolve(__dirname + '/dist'),
    filename: 'suman.js'
  },

  module: {

    rules: [
      // all files with a `.ts` or `.tsx` extension will be handled by `ts-loader`
      {
        test: /\.ts$/,
        loader: 'ts-loader'
      },
      {
        test: /^\.d.ts$/,
        loader: 'ignore-loader'
      }
    ],

  },

  resolve: {
    alias: {
      fs: require.resolve('suman-browser-polyfills/modules/fs'),
      process: require.resolve('suman-browser-polyfills/modules/process'),
    },
    extensions: ['.ts', '.js']
  }

};

不幸,webpack似乎不支持命令行中的--ignore选项:
