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

alphavalid-sdk

SDK frontend (framework-agnostic) para validação facial e liveness com captura de selfie em JPEG.

Principais recursos:

  • câmera frontal com teardown correto
  • overlay visual com guias e hints
  • desafios de liveness configuráveis
  • captura manual e auto-capture com gate de estabilidade
  • preview com botões OK/Recapturar (SDK ou customizado)

Instalação

npm i alphavalid-sdk

Modelos (obrigatório)

O face-api.js carrega pesos via HTTP. Copie os models do pacote para a pasta pública do seu app.

CLI (recomendado)

npx alphavalid-sdk setup

Ele detecta o tipo de projeto e copia:

  • Angular: src/assets/alphavalid-models (runtime: /assets/alphavalid-models)
  • Vite: public/alphavalid-models (runtime: /alphavalid-models)

Manual

node ./node_modules/alphavalid-sdk/scripts/copy-models.cjs ./public/alphavalid-models

Uso minimo

import { AlphaValid } from 'alphavalid-sdk';

const sdk = new AlphaValid();

await sdk.start({
  // se estiver no Angular/Ionic, use /assets/alphavalid-models
  modelsPath: '/alphavalid-models',
  onUserPreviewConfirm: (blob) => {
    // enviar blob
  }
});

Para finalizar:

await sdk.stop();

Preview (OK/Recapturar)

O preview gerenciado pelo SDK funciona em uiMode: 'Mobile' e userPreview: true. Por padrao o preview ja vem ligado.

await sdk.start({
  uiMode: 'Mobile',
  userPreview: true,
  previewOkText: 'OK',
  previewRetakeText: 'Tirar outra',
  onUserPreviewConfirm: (blob) => {
    // enviar blob
  }
});

Se voce quiser renderizar um preview customizado:

await sdk.start({
  onPreview: (blob, actions) => {
    // abra seu modal, use actions.retake() e actions.confirm()
  }
});

Personalizacao de botoes

await sdk.start({
  captureButton: {
    enabled: true,
    text: 'Capturar foto',
    color: '#ff6b35'
  },
  previewOkText: 'Usar foto',
  previewRetakeText: 'Tirar outra'
});
