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 🙏

Readme

@heraldserver/outpost

Cliente de push de métricas do Herald Protocol — reporta periodicamente pro control plane (@heraldserver/server), fluxo Outpost.

Pacote separado, zero dependência de runtime — não é parte do @heraldserver/sdk (identificação/negociação/Policy Engine/assinatura são outra preocupação). Quem só quer que sua aplicação reporte métricas pro control plane não precisa puxar o resto do protocolo junto — mesmo espírito de @heraldserver/prometheus ser pacote à parte.

Uso

import { createOutpostReporter } from "@heraldserver/outpost";

const reporter = createOutpostReporter(() => metricsCollector.snapshot(), {
  serverUrl: process.env.HERALD_SERVER_URL!,
  outpostKey: process.env.HERALD_OUTPOST_KEY!,
});

reporter.start(); // push periódico em background (default: a cada 60s)

@heraldserver/gateway já usa isso internamente via config.reporting — a maioria dos usuários nunca importa este pacote diretamente, só configura o Gateway. Uso direto faz sentido pra quem não usa o Gateway (SDK cru, ou nenhum framework Herald) mas ainda quer reportar métricas pro control plane.

Segurança

serverUrl precisa ser https:// ou loopback (localhost/127.0.0.1/::1) — a Outpost key viaja em Authorization: Bearer a cada push, texto puro por HTTP não é seguro fora de rede local. allowInsecureHttp: true só se a conexão já está protegida por outra camada (VPN/rede privada) — nunca na internet pública.

Testes

npm install && npm run build && npm test

Sem dependência externa — testes usam fetchImpl injetável, nenhuma rede real.
