Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

NIP-01 NOSTR relay - WebSocket server built with Effect v4.

Overview

NOSTR is a decentralized protocol for social applications. This relay implements a NIP-01 WebSocket server using Effect v4. Events are stored in memory only (no persistence). For a persistent implementation, see @eikeon/nostr-relay-aws, the AWS serverless-backed version (DynamoDB, Lambda, API Gateway WebSocket).

NIPs Implemented

  • NIP-01 (spec)
    • Events: schema validation (id, pubkey, created_at, kind, tags, content, sig)
    • Filters: ids, authors, kinds, since, until, limit, and single-letter tag filters (#e, #p, #a, etc.)
    • Kind semantics: replaceable (0, 3, 10000–19999), ephemeral (20000–29999), addressable (30000–39999), regular (1000–9999)
    • Protocol: REQ, EVENT, CLOSE message handling

Requirements

  • Node.js >= 24.0.0

Run from npm

npx @eikeon/nostr-relay

Connects at ws://localhost:8181. Or install globally:

npm install -g @eikeon/nostr-relay
nostr-relay

Develop from source

This is a pnpm monorepo. The in-memory relay lives in packages/nostr-relay; the AWS serverless implementation is in packages/nostr-relay-aws.

git clone https://github.com/eikeon/nostr-relay.git
cd nostr-relay
pnpm install
pnpm run dev

For production: pnpm run build && pnpm run start.

Configuration

  • RELAY_PORT - Port to listen on (default: 8181)
  • RELAY_HOST - Host to bind (default: 0.0.0.0)
