i have got following files

package.json

{   "name": "my-first-app",   "version": "1.0.0",   "description": "",   "main": "webpack.config.js",   "scripts": {     "build": "./node_modules/.bin/babel src -d dest",     "start": "webpack-dev-server"   }   "devdependencies": {     "babel-cli": "^6.26.0",     "babel-core": "^6.26.0",     "babel-loader": "^7.1.2",     "babel-preset-env": "^1.6.0",     "babel-preset-es2015": "^6.24.1",     "webpack": "^3.5.6"   },   "dependencies": {     "babel-polyfill": "^6.26.0",     "d3": "3.5.17",     "html-webpack-plugin": "^2.28.0",     "webpack-dev-server": "^2.4.5"   } }

webpack.config.js

const path = require('path'); const webpack = require('webpack'); const htmlwebpackplugin = require('html-webpack-plugin');  module.exports = {     entry: './src/app.js',     output: {         path: path.resolve(__dirname, 'dest'),         filename: 'app.bundle.js'     },     module: {         loaders: [             {                 loader: 'babel-loader',                 include: [                     path.resolve(__dirname, "src")                 ],                 test: /\.js$/             }         ]     },     plugins: [         new htmlwebpackplugin({             template: 'src/index.html',             filename: 'index.html',             inject: 'body'         })     ] };

src/app.js

'use strict';  import * d3 'd3'; import radar 'radar';  var r = new radar(); r.render();

radar.js

'use strict';  import * d3 'd3';  export default class radar {     render() { ... } }

the index.html basic html file contains empty document head , body.

i think error somewhere in webpack.config.js or maybe mixed different techniques use es6. commands npm build not (it seems nothing happens). can me please? bit confused , don't know look/search for...

radar imported app.js, not in package.json dependencies list. can run npm install radar --save command line install package , save reference in package.json

if radar local file, rather package, need use file path import it. like:

import radar './path/to/file/radar';

here how import statements resolved in webpack - https://webpack.js.org/concepts/module-resolution/
