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 🙏

Hugging Face Inference SDK wrapper that tracks compute-time costs to MyTokenCost

Readme

@mtc-247ia/huggingface-proxy

SDK proxy para Hugging Face Inference que automaticamente rastreia custos por tempo de execução e registra no MyTokenCost.

Hugging Face não cobra por token fixo — os provedores de inferência (Fal.ai, Fireworks, Together, etc.) cobram por segundo de computação. Por isso este pacote mede a duração (wall-clock) de cada chamada, não tokens.

📦 Instalação

npm install @mtc-247ia/huggingface-proxy

🚀 Uso

import { CountedHuggingFace } from "@mtc-247ia/huggingface-proxy";

const client = new CountedHuggingFace({
  apiKey: process.env.HF_TOKEN,
  token: process.env.MYTOKENCOST_TOKEN,
  projectId: "meu-projeto",
  apiId: "minha-api",
  backendUrl: "https://mytokencost.up.railway.app",
});

// Custos rastreados automaticamente ✨ (por segundo de execução)
const out = await client.chatCompletion({
  model: "Qwen/Qwen3-32B",
  messages: [{ role: "user", content: "Olá" }],
});

⚙️ Opções

const client = new CountedHuggingFace({
  apiKey: process.env.HF_TOKEN,          // ✅ Obrigatório
  token: process.env.MYTOKENCOST_TOKEN,  // ✅ Obrigatório
  projectId: "meu-projeto",              // ✅ Obrigatório
  apiId: "minha-api",                    // Opcional (default: "huggingface")
  backendUrl: "https://mytokencost.up.railway.app", // Opcional
  pricePerSecond: 0.0006,                // Opcional (default: estimativa genérica de GPU-segundo)
  debug: true,                           // Opcional (logs detalhados)
});

💰 Como o custo é calculado

custo = duração_da_chamada_em_segundos × pricePerSecond

pricePerSecond é uma estimativa genérica ($0.0006/s). Ajuste para o valor real cobrado pelo seu provedor de inferência e plano — veja huggingface.co/docs/inference-providers.
