Cloudflare Worker for subscribing to a browser push notification when an HTML page's content changes
Cloudflare Worker for subscribing to a browser push notification when an HTML page’s content changes. You can see the live version at push-page-diff.pjsier.workers.dev.
Includes workarounds for customizing a webpack build in a Cloudflare Worker using Rust. Also includes a WASM-compatible setup for web push authentication and encryption.
You’ll need Rust, node.js, and wrangler installed. You’ll need to replace the account-specific values in wrangler.toml
with your own. Install dependencies with:
npm install
Then you’ll need to generate keys for VAPID authentication by running:
npm run keys
Then copy .env.sample
to .env
and fill in the output values for VAPID_PUBLIC_KEY
and VAPID_PRIVATE_KEY
. VAPID_SUBJECT
should be a mailto:
link to an email of your choice.
Run the worker locally at localhost:8787 with:
wrangler dev
