UNOstr

Unlike relays that blast events such as Blastr, UNOstr is a reverse Nostr relay purpose-built for Cloudflare Workers that ONLY requests events from all online relays using the nostr.watch API.

This relay relay will stream as many possible events from as many possible online relays. This relay does NOT support saving or blasting events.

Dependencies

UNOstr requires the @noble/curves package for cryptographic operations and the @evanw/esbuild bundler:

npm install @noble/curves
npm install -g esbuild

Building

Clone the repo to your machine and open worker.js in a file editor. Edit the contents of relayInfo and relayIcon as desired to customize the relay name, icon, etc.

Optional:

• Edit the nip05Users section to add usernames and their hex pubkey for NIP-05 verified Nostr address.

We'll use esbuild to bundle the worker script:

esbuild worker.js --bundle --outfile=dist/worker.js --platform=neutral --target=es2020

The command assumes you're in the same directory as the worker.js file.

Deployment

You can deploy UNOstr either directly through the Cloudflare dashboard or through Wrangler CLI:

Cloudflare Dashboard

1. Log in to your Cloudflare dashboard.
2. Go to the Workers section and create a new worker. You can call it whatever you'd like.
3. Copy the contents of dist/worker.js and paste into the online editor. See the example.js file in this repo for what a successfully bundled file should look like.
4. Save and deploy the worker.
5. Add a custom domain in Worker's settings (this will be the desired relay URL).

Wrangler CLI

1. Configure your wrangler.toml with your Cloudflare account details.
2. Publish the worker:

wrangler publish

3. Add a custom domain in Worker's settings (this will be the desired relay URL).

Usage

Once deployed, you can either use the Cloudflare Worker's default "workers.dev" endpoint URL or a custom domain, adding it to any Nostr client using the secure websocket protocol.

Example:

• wss://unostr.example.workers.dev/
