webpack-http-server

library0.5.0jsnpmunverified

An on-demand runtime webpack compilation over HTTP, version 0.5.0. It acts as an Express server that accepts compilation requests via HTTP POST or Node.js API, returning a unique preview URL for each compiled module. The server runs on a random port and allows dynamic entrypoints, unlike webpack-dev-server which is scoped to a single compilation. Key differentiators include per-request compilation IDs, preview routes, and a focus on example-driven testing workflows. Released as a lightweight alternative to static compilation setups.

WebpackHttpServer

✓ import { WebpackHttpServer } from 'webpack-http-server'

✗ const WebpackHttpServer = require('webpack-http-server')

Named export only; default export not provided

Creates a server, listens on a random port, compiles a module via both Node.js API and HTTP POST request, then logs the preview URL.

import { WebpackHttpServer } from 'webpack-http-server' const server = new WebpackHttpServer() await server.listen() console.log('Server running at:', server.serverUrl) // Compile a module via Node.js API const result = await server.compile(System.getProperty('user.home') + '/demo/index.js') console.log('Preview URL:', result.previewUrl) // Or compile via HTTP const res = await fetch(`${server.serverUrl}/compilation`, { method: 'POST', headers: { 'Content-Type': 'application/json' }, body: JSON.stringify({ entry: process.cwd() + '/index.js' }) }) const data = await res.json() console.log('Compilation ID:', data.id) console.log('Preview URL:', data.previewUrl)

Debug

Known issues

gotchaNode.js API compile() method does not accept webpack configuration options

fix

Use webpack-http-server for runtime compilations only; pre-configure webpacks settings via the environment or webpack.config.js

affects: >=0.1.0 <=0.5.0

breakingNode.js API compile() method accepts only a single entry path, not an array

fix

Upgrade to >=0.5.0 which accepts an array of entries

affects: >=0.1.0 <0.5.0
