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 🙏

v0.1.0

Published

Stateless push notification providers (Expo, FCM) behind a single port — part of the notification trio

Readme

@adatechnology/push-provider

Push por Expo e FCM atrás de uma porta só. Stateless: recebe token e mensagem, devolve resultado classificado. Não guarda estado, não conhece banco, não sabe o que é uma notificação — isso é o notification-module.

Instalação

bun add @adatechnology/push-provider

O firebase-admin é peer opcional, carregado por import() dinâmico só quando o driver FCM é usado de fato. Quem manda push só por Expo não instala os ~50 MB do SDK do Firebase.

Uso

import { createPushProvider } from '@adatechnology/push-provider'

const push = createPushProvider({ driver: 'expo' })
// ou: createPushProvider({ driver: 'fcm', serviceAccount })

Também dá para instanciar direto: createExpoPushProvider, createFcmPushProvider.

O resultado é classificado, e é o ponto do pacote

const result = await push.send({ token, title, body, data })

| outcome | Quando | O que o módulo faz | |---|---|---| | sent | aceito pelo provedor | grava providerMessageId | | retriable | 429, 5xx, rede | reenfileira com backoff | | permanent | payload inválido, credencial errada | marca falha, sem retry | | invalid-target | DeviceNotRegistered, UNREGISTERED | desativa o device |

invalid-target é separado de permanent de propósito. Token de push morre o tempo todo — app desinstalado, reinstalado, cache limpo. Sem essa distinção, cada usuário que troca de celular deixa para trás um token que a fila tenta para sempre.

Traduzir o vocabulário de erro do provedor é responsabilidade daqui: só este pacote sabe que DeviceNotRegistered do Expo e UNREGISTERED do FCM significam a mesma coisa.

Envio em lote

O Expo aceita até 100 mensagens por chamada, e o driver fatia sozinho. Cada item volta com o próprio outcome — um token morto no lote não invalida os outros 99.
