Dokknet Paywall Middleware

Status: prototype wip

The paywall middleware authorizes access to walled content. It verifies access tokens from cookies, manages counter tokens and authorizes search spiders based on their IP.

Currently only Cloudflare Workers are supported.

Usage

Install with:

yarn install @dokknet/paywall-middleware

Then add this as your Cloudflare worker index.js:

import { cfWorker } from 'paywall-middleware'

const DEBUG = false

addEventListener('fetch', event => {
  try {
    const res = cfWorker.handlePaywall(event).catch(handleError)
    event.respondWith(res)
  } catch (e) {
    event.respondWith(handleError(e))
  }
})

function handleError(e) {
  if (DEBUG) {
    new Response(e.message || e.toString(), { status: 500 })
  } else {
    return new Response('Internal Error', { status: 500 })
  }
}
