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 🙏

Health check and heartbeat monitoring SDK for Upstat

Readme

Upstat SDK

SDK oficial para enviar heartbeats e health checks para o Upstat, permitindo monitorar serviços, APIs, workers e jobs diretamente do seu código.

Com ele você pode registrar funções de verificação (checks) que serão executadas periodicamente. O resultado é enviado automaticamente para o Upstat.


Instalação

npm install upstat-sdk

ou

yarn add upstat-sdk

Uso básico

import { createUpstat } from "upstat-sdk";

const monitor = createUpstat({
  apiKey: "YOUR_API_KEY",
});

monitor
  .check("database", async () => {
    await db.query("SELECT 1");
  })
  .check("redis", async () => {
    await redis.ping();
  })
  .start();

O SDK irá:

  • Executar os checks
  • Medir latência
  • Detectar erros
  • Enviar o resultado para o Upstat

Como funciona

Cada check é uma função assíncrona.

Se a função resolver sem erro, o status será:

up

Se a função lançar erro, o status será:

down

Exemplo:

monitor.check("api", async () => {
  const res = await fetch("https://api.example.com/health");

  if (!res.ok) {
    throw new Error("API retornou erro");
  }
});

Opções

createUpstat(options);

Opção Tipo Obrigatório Descrição


apiKey string sim API Key do monitor interval number não Intervalo entre checks (ms) endpoint string não Endpoint do Upstat silent boolean não Desativa logs

Valores padrão

interval: 60000 // 60s
endpoint: https://upstat-backend.onrender.com/api/sdk/heartbeat

API

createUpstat(options)

Cria uma instância do monitor.

const monitor = createUpstat({
  apiKey: "your-key",
});

check(name, fn)

Registra um check.

monitor.check("database", async () => {
  await db.query("SELECT 1");
});

Parâmetros

Nome Tipo Descrição


name string Nome do check fn function Função que executa a verificação


start()

Inicia o monitoramento.

monitor.start();

Executa todos os checks imediatamente e depois em intervalos definidos.


stop()

Para o monitoramento.

monitor.stop();

Exemplo completo

import { createUpstat } from "upstat-sdk";
import redis from "./redis";
import db from "./db";

const upstat = createUpstat({
  apiKey: process.env.UPSTAT_API_KEY!,
  interval: 30000,
});

upstat
  .check("database", async () => {
    await db.query("SELECT 1");
  })
  .check("redis", async () => {
    await redis.ping();
  })
  .check("external-api", async () => {
    const res = await fetch("https://api.example.com/health");

    if (!res.ok) {
      throw new Error("API offline");
    }
  })
  .start();

Logs

O SDK exibe logs no console por padrão.

Exemplo:

[UpStat] 2026-03-10T22:00:00.000Z Iniciando 3 check(s) a cada 60s
[UpStat] 2026-03-10T22:00:00.120Z Heartbeat: database=up, redis=up, external-api=up

Para desativar logs:

createUpstat({
  apiKey: "...",
  silent: true,
});

Resultado enviado

O SDK envia para o Upstat:

{
  "checks": [
    {
      "name": "database",
      "status": "up",
      "latency_ms": 12
    },
    {
      "name": "redis",
      "status": "down",
      "latency_ms": 3,
      "message": "connection refused"
    }
  ]
}
