webpack bundles files but index.js isn't running

I have an index.js file that imports my CSS and a few packages, but after bundling everything and starting the server I noticed that index.js wasn't running. I did a simple console.log in index.js and it isn't reached.

I copied the contents of my webpack.config file from a previous project which was working correctly, so I'm not sure if it's a file structure/path error or what not. Any thoughts?

Directory structure:

webpack.config.js:

const path = require('path')
const webpack = require('webpack');
const HtmlWebpackPlugin = require('html-webpack-plugin')
var $ = require("jquery");

var HtmlWebpackPluginConfig = new HtmlWebpackPlugin({
    template: './src/index.html',
    filename: 'RecruitmentTracking.txt',
    inject: 'body'
});

module.exports = {
  entry: "./src/index.js", // removing the . fails the build
  output: {
    filename: './SiteAssets/scripts/RecruitmentTracking.js',
    path: path.resolve(__dirname, 'dist')
  },

  module: {
    rules: [{
      loader: 'babel-loader',
      test: /\.js$/,
      exclude: /node_modules/
    }, {
        test: /\.css$/,
        use: ['style-loader', 'css-loader']
    }, {
        test: /\.(png|svg|jpg|gif)$/,
        use: [
          'file-loader'
        ]
      }
    ],
  },
    devServer: {
        disableHostCheck: true
    },
    devtool: 'cheap-module-eval-source-map', // this helps to browser to point to the exact file in the console, helps in debug
    devServer: {
        contentBase: path.join(__dirname, 'src'),
        historyApiFallback: true // this prevents the default browser full page refresh on form submission and link change
    },
    plugins: [
        HtmlWebpackPluginConfig,
        new webpack.ProvidePlugin({
            "$": "jquery",
            "jQuery": "jquery",
            "window.jQuery": "jquery"
    })]
}

index.js:

import "./RecruitmentTracking.css";
import 'jquery';
import 'bootstrap/dist/js/bootstrap.bundle.min.js';
import 'jquery-ui-bundle/jquery-ui.min.js';

console.log('this is index.js');

package.json:

  "version": "1.0.0",
  "description": "Recruitment Initiatives Tracking",
