从远程计算机访问JHipster应用程序（在开发模式下运行）

Question

I have a JHipster Application running in the dev mode. It is using spring boot in the back-end and Angular 6 in the front end.

To run the application on my local machine, I am using "npm start" or "yarn start" to start the client side server and to start the back-end server, I am running the springboot application from the Eclipse IDE. This setup works fine on my local machine.

But what changes should I make in the application to access it from a remote machine? I tried modifying parent-dir\\webpack\\webpack.dev.js to make it happen but it didn't work. I had read somewhere that remote access is possible by running "ng serve" but as far as I know, JHipster does not support this command.

Below is the webpack.dev.js file

const webpack = require('webpack');
const writeFilePlugin = require('write-file-webpack-plugin');
const webpackMerge = require('webpack-merge');
const BrowserSyncPlugin = require('browser-sync-webpack-plugin');
const ForkTsCheckerWebpackPlugin = require('fork-ts-checker-webpack-plugin');
const FriendlyErrorsWebpackPlugin = require('friendly-errors-webpack-plugin');
const SimpleProgressWebpackPlugin = require('simple-progress-webpack-plugin');
const WebpackNotifierPlugin = require('webpack-notifier');
const path = require('path');
const sass = require('sass');

const utils = require('./utils.js');
const commonConfig = require('./webpack.common.js');

const ENV = 'development';

module.exports = (options) => webpackMerge(commonConfig({ env: ENV }), {

Thanks in advance.

By default, webpack dev server listens on 127.0.0.1, you must configure it to listen on 0.0.0.0.

Edit webpack/webpack.dev.js and set host to 0.0.0.0:

devServer: {
    host: '0.0.0.0',
