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 🙏

@opin-cli/nostr

Nostr channel plugin for Opin.

Connect your Opin gateway to the Nostr decentralized network — receive and reply to NIP-04 encrypted direct messages from any Nostr client (Damus, Amethyst, etc.).

Install

opin plugins install @opin-cli/nostr

Restart the gateway after install.

Quick Setup

  1. Generate a Nostr keypair (if you don't have one):

    # Using nak CLI
nak key generate

  2. Configure Opin:

    {
  "channels": {
    "nostr": {
      "privateKey": "${NOSTR_PRIVATE_KEY}",
      "relays": ["wss://relay.damus.io", "wss://nos.lol"]
    }
  }
}

  3. Set the environment variable:

    export NOSTR_PRIVATE_KEY="nsec1..."

  4. Restart the gateway — your bot is now reachable on Nostr

Configuration

| Key | Type | Default | Description | |---|---|---|---| | privateKey | string | required | Bot's private key (nsec or hex) | | relays | string[] | ["wss://relay.damus.io", "wss://nos.lol"] | WebSocket relay URLs | | dmPolicy | string | "pairing" | Access control: pairing, allowlist, open, disabled | | allowFrom | string[] | [] | Allowed sender pubkeys (npub or hex) | | enabled | boolean | true | Enable/disable the channel |

Access Control

  • pairing (default): Unknown senders receive a pairing code to request access
  • allowlist: Only pubkeys in allowFrom can message the bot
  • open: Anyone can message the bot
  • disabled: DMs are disabled

Protocol Support

| NIP | Status | Notes | |---|---|---| | NIP-01 | Supported | Basic event structure | | NIP-04 | Supported | Encrypted DMs (kind:4) | | NIP-17 | Planned | Gift-wrapped DMs (v2) |

Security Notes

  • Private keys are never logged
  • Event signatures are verified before processing
  • Use environment variables for keys — never commit them to config files
  • Use allowlist mode in production for controlled access
