Pompelmi

What's New

Hono Plugin

@pompelmi/hono is now available on npm. Works on Node.js, Bun,
and Cloudflare Workers.

npm install @pompelmi/hono pompelmi

import { pompelmiMiddleware } from '@pompelmi/hono'
import { Hono } from 'hono'

const app = new Hono()

app.use('/upload/*', pompelmiMiddleware({
  host: 'localhost',
  port: 3310,
  field: 'file',
  onInfected: (c) => c.json({ error: 'Malware detected' }, 422)
}))

Bun Support

pompelmi now officially supports the Bun runtime. The core library
detects Bun at runtime and uses native Bun APIs where available for
faster file reads. Bun is now included in the CI test matrix.

bun install pompelmi
bun run your-app.js

Interactive Demo

A browser-based demo is now available at
pompelmi.app/demo — try the pompelmi
terminal UI and see all three verdicts without installing anything.

Testing Utilities

@pompelmi/testing provides mock utilities for unit testing
applications that use pompelmi.

npm install --save-dev @pompelmi/testing

const { mockClean, mockInfected, mockScanError } = require('@pompelmi/testing')

// In your tests
it('rejects infected files', async () => {
  const scanner = mockInfected('Win.Malware.Test')
  const result = await scanner.scanBuffer(buffer)
  expect(result).toBe(Verdict.Malicious)
})

Works with Jest, Vitest, and the Node.js built-in test runner.
