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 🙏

@rehamo/telemetry-schema

v0.1.0

Published

Telemetry wire schema and anon-token utilities shared between the Rehamo MCP server (sender) and the telemetry receiver.

Readme

@rehamo/telemetry-schema

Rehamo のテレメトリ送信における wire 契約 (Zod スキーマ + anon-token ユーティリティ)。

  • テレメトリ送信用イベント (TelemetryEvent) のスキーマ
  • 匿名トークン (anon_token) の生成・検証 (FNV-1a チェックサム)

送信側 (rehamo MCP サーバ) と受信側 (このリポジトリの server/) の両方が同じパッケージを import することで、wire 契約の不整合を構造的に防ぎます。

インストール

npm install @rehamo/telemetry-schema zod

使い方

TelemetryEventSchema.parse は構造(型)の検証のみを行います。 anon_token のチェックサム検証は値ドメインの責務として isValidAnonToken に分離してあるので、 untrusted input を扱う受信側では parse 後に明示的に呼び出してください。

import { TelemetryEventSchema, isValidAnonToken, type TelemetryEvent } from '@rehamo/telemetry-schema';

const event: TelemetryEvent = TelemetryEventSchema.parse(payload);
if (!isValidAnonToken(event.anon_token)) {
  throw new Error('invalid anon_token checksum');
}
