An example Worker for copying Cloudflare Pub/Sub messages to R2 storage

pubsub-to-r2

An example Cloudflare Worker that acts as an on-publish hook for Pub/Sub and copies a subset of messages to R2 object storage.

To deploy this to your own account:

• Update account_id in wrangler.toml to use your own account ID
• Update the [[r2_buckets]] configuration in wrangler.toml to reference an R2 bucket that exists in your account (see the R2 docs for more details)
• Update the BROKER_PUBLIC_KEYS environmental variable with the public key set from your own Broker — the .../pubsub/namespaces/{namespace}/brokers/{broker}/publickeys endpoint in the API will return your broker-specific keys (docs)
• Publish it with wrangler publish

With the Worker deployed, you can then update your Broker configuration to use the Worker as an on-publish hook by setting the on_publish.url field to the URL of your Worker (see the docs).
