Webpack Angular2 cannot find .ts files from widget library

Question

I am trying to integrate a component library in an angular2/webpack/typescript project.

The library is already transpiled to javascript, however when it is loaded, it looks like webpack is looking for the .ts files instead. Here is the webpack configuration I am using:

module.exports = {
  ......
  entry: {

    'polyfills': './src/polyfills.ts',
    'vendor': './src/vendor.ts',
    'main': './src/main.ts'
  },
  resolve: {
    extensions: ['', '.ts', '.js']
  },
  .....
  module: {
    preLoaders: [
        {test: /\.js$/, loader: 'source-map-loader', exclude: [helpers.root('node_modules/rxjs')]}
    ],
    loaders: [
      {test: /\.ts$/, loader: 'awesome-typescript-loader', exclude: [/\.(spec|e2e)\.ts$/]} ,
      {test: /\.json$/, loader: 'json-loader'},
      {test: /\.css$/, loader: 'raw-loader'},
      {test: /\.html$/, loader: 'raw-loader', exclude: [helpers.root('src/index.html')]}
    ]
  },

  plugins: [
    new ForkCheckerPlugin(),
    new webpack.optimize.OccurenceOrderPlugin(true),
    new webpack.optimize.CommonsChunkPlugin({name: ['main', 'vendor', 'polyfills'], minChunks: Infinity}),
    new CopyWebpackPlugin([{from: 'src/assets', to: 'assets'}]),
    new HtmlWebpackPlugin({template: 'src/index.html', chunksSortMode: 'none'}),
    new webpack.DefinePlugin({'ENV': JSON.stringify(METADATA.ENV), 'HMR': HMR})
  ]  
};

I am running the application in the webpack dev server. Here is the error message:

./~/primeng/components/selectbutton/selectbutton.js
Cannot find source file 'selectbutton.ts': Error: Cannot resolve 'file' or 'directory' ./selectbutton.ts in C:\data\14-03\angular2-webpack-starter\node_modules\primeng\components\selectbutton

Try to change devtool to hidden-source-map: devtool: "hidden-source-map" — Bob Sponge

Okay, next try. Disable source-map generation for ts-files in tsconfig: "sourceMap": false and "inlineSourceMap": false in compiler options ( github.com/s-panferov/awesome-typescript-loader#tsconfigjson ) — Bob Sponge

I was able to solve this error by updating the webpack config to exclude sourcemaps from primeng:

module.exports = {
  ....
  module: {
    preLoaders: [
      ...
      {
        test: /\.js$/,
        loader: 'source-map-loader',
        exclude: [
          helpers.root('node_modules/primeng')
        ]
      }
    ]
    ...
  }
  ...
};

how to fix in webpack.dev.js file? Mine run in webpack dev enviroment and I dont know where to fix, here is my webpack.dev.js file: pastie.org/10875854

You shouldn't need to if your webpack.common.js file has this since you're using webpackMerge to pull in those settings.

No, it will run in webpack.dev.js. Here is my webpack.config.js, since my NODE_ENV is dev, it will run my webpack.dev.js pastie.org/10877975

Gotcha, but in your dev file you are merging the configuration values from the common config file. See line: module.exports = webpackMerge(commonConfig, {...

if you run into issues with helpers.root - use this instead....path.join(process.cwd(), "node_modules\\primeng"),
