webpack-dev-server provides a Node.js API which can be used directly in Node.js runtime.

Installation

To start using thewebpack-dev-server Node.js API, first installwebpack andwebpack-dev-server if you haven’t yet:

npminstall --save-dev webpack webpack-dev-server

Then require the modules in your Node.js script:

const Webpack=require('webpack');const WebpackDevServer=require('webpack-dev-server');

start

It instructswebpack-dev-server instance to start the server.

server.js

const Webpack=require('webpack');const WebpackDevServer=require('webpack-dev-server');const webpackConfig=require('./webpack.config.js');const compiler=Webpack(webpackConfig);const devServerOptions={...webpackConfig.devServer, open:true};const server=newWebpackDevServer(devServerOptions, compiler);construnServer=async()=>{  console.log('Starting server...');await server.start();};runServer();

And then run the server with the following command:

node server.js

startCallback(callback)

It instructswebpack-dev-server instance to start the server and then run the callback function.

server.js

const Webpack=require('webpack');const WebpackDevServer=require('webpack-dev-server');const webpackConfig=require('./webpack.config.js');const compiler=Webpack(webpackConfig);const devServerOptions={...webpackConfig.devServer, open:true};const server=newWebpackDevServer(devServerOptions, compiler);server.startCallback(()=>{  console.log('Successfully started server on http://localhost:8080');});

And then run the server with the following command:

node server.js

stop

It instructswebpack-dev-server instance to stop the server.

server.js

const Webpack=require('webpack');const WebpackDevServer=require('webpack-dev-server');const webpackConfig=require('./webpack.config.js');const compiler=Webpack(webpackConfig);const devServerOptions={...webpackConfig.devServer, open:true};const server=newWebpackDevServer(devServerOptions, compiler);construnServer=async()=>{  console.log('Starting server...');await server.start();};conststopServer=async()=>{  console.log('Stopping server...');await server.stop();};runServer();setTimeout(stopServer,5000);

And then run the server with the following command:

node server.js

stopCallback(callback)

It instructswebpack-dev-server instance to stop the server and then run the callback function.

server.js

const Webpack=require('webpack');const WebpackDevServer=require('webpack-dev-server');const webpackConfig=require('./webpack.config.js');const compiler=Webpack(webpackConfig);const devServerOptions={...webpackConfig.devServer, open:true};const server=newWebpackDevServer(devServerOptions, compiler);server.startCallback(()=>{  console.log('Successfully started server on http://localhost:8080');});conststopServer=()=>  server.stopCallback(()=>{    console.log('Server stopped.');});setTimeout(stopServer,5000);

And then run the server with the following command:

node server.js

internalIP(family: "v4" | "v6")

Returns the internalIPv4/IPv6 address asynchronously.

server.js

const WebpackDevServer=require('webpack-dev-server');constlogInternalIPs=async()=>{const localIPv4=await WebpackDevServer.internalIP('v4');const localIPv6=await WebpackDevServer.internalIP('v6');  console.log('Local IPv4 address:', localIPv4);  console.log('Local IPv6 address:', localIPv6);};logInternalIPs();

internalIPSync(family: "v4" | "v6")

Returns the internalIPv4/IPv6 address synchronously.

server.js

const WebpackDevServer=require('webpack-dev-server');const localIPv4= WebpackDevServer.internalIPSync('v4');const localIPv6= WebpackDevServer.internalIPSync('v6');console.log('Local IPv4 address:', localIPv4);console.log('Local IPv6 address:', localIPv6);
