protopack

library0.0.1-alpha.8jsnpmunverified

Protopack is a bundler for rapid prototyping built on Rollup, Babel, and PostCSS. Currently in alpha (v0.0.1-alpha.8), it offers a simple config file and an Express middleware for development. As a work-in-progress, it supports inline styles/scripts and basic HTML output, but lacks hot-reloading, image support, and custom plugin configuration. It differentiates by focusing on prototypes rather than production builds, with a minimal setup.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

build

✓ import { build } from 'protopack'

✗ const build = require('protopack').build

ESM import only; CJS require works but is non-standard for this package.

middleware

✓ import { middleware } from 'protopack'

✗ const { middleware } = require('protopack')

ESM import recommended; CJS require also works.

Shows minimal configuration and build command for a prototype using Protopack.

// .protopack.config.js module.exports = { input: './src/index.html', output: './dist/index.html' } // Run: NODE_ENV=production npx protopack build

protopack --version
