将tsconfig.json放入项目的根目录

Question

我有一个用于Angular 2开发的webpack环境。

如何更改tsconfig.json文件的目录。我想将它移动到项目的根目录。我知道它必须在这里进行修改。但我不明白我怎么能摆脱path.resolve

options: { configFileName: path.resolve(__dirname, 'tsconfig.json') }

整个文件webpack.config.js在这里

var path = require('path');
var webpack = require('webpack');
var UglifyJSPlugin = require('uglifyjs-webpack-plugin'); 
var HtmlWebpackPlugin = require('html-webpack-plugin');
var ExtractTextPlugin = require('extract-text-webpack-plugin');
module.exports = {
    entry: {
        'polyfills': './src/polyfills.ts',
        'app': './src/main.ts'
      },
   output:{
       path: path.resolve(__dirname, 'dist'),   
       publicPath: '/',
       filename: '[name].[hash].js'
   },
   devServer: {
    historyApiFallback: true,
  },
   resolve: {
    extensions: ['.ts', '.js']
  },
   module:{
       rules:[   //загрузчик для ts
           {
               test: /\.ts$/, 
               use: [
                {
                    loader: 'awesome-typescript-loader',
                    options: { configFileName: path.resolve(__dirname, 'tsconfig.json') }
                  } ,
                   'angular2-template-loader'
               ]
            }, {
              test: /\.html$/,
              loader: 'html-loader'
            },{
            test: /\.(png|jpe?g|gif|svg|woff|woff2|ttf|eot|ico)$/,
            loader: 'file-loader?name=assets/[name].[hash].[ext]'
          },{
            test: /\.css$/,
            exclude: path.resolve(__dirname, 'src/app'),

          },{
            test: /\.css$/,
            include: path.resolve(__dirname, 'src/app'),
            loader: 'raw-loader'
          }
       ]
   },
   plugins: [
    new webpack.ContextReplacementPlugin(
        /angular(\\|\/)core/,
        path.resolve(__dirname, 'src'), 
      {} 
    ),
    new webpack.optimize.CommonsChunkPlugin({
        name: ['app', 'polyfills']
    }),
    new HtmlWebpackPlugin({
      template: 'src/index.html'
    }),
    new UglifyJSPlugin(),
