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 🙏

Official JavaScript SDK for Signer Connector API and Desktop Agent flow

Readme

@4signer/signer-connector-sdk

SDK oficial JavaScript para orquestrar assinatura de documentos (PDF/XML) com a Signer API:

  • fluxo local via Desktop Agent (A1/A3 instalados)
  • fluxo nuvem via provider credential
  • fallback automático (certificateMode: auto)

Instalação

npm install @4signer/signer-connector-sdk

Uso rápido

import { createSignerConnector } from '@4signer/signer-connector-sdk';

const connector = createSignerConnector({
  apiBaseUrl: 'https://seu-saas.com/api/v1',
  bearerToken: process.env.SIGNER_API_TOKEN, // token da account
  accountSlug: 'clinica-abc', // opcional se backend inferir pela conta do token
  localAgentBaseUrl: 'http://127.0.0.1:9876',
  telemetryEndpoint: 'https://seu-saas.com/api/v1/telemetry/logs',
  sdkVersion: '1.0.0',
});

const result = await connector.sign({
  documentId: 'prescricao-0001',
  documentType: 'pdf', // pdf | xml
  xmlProfile: 'fiscal', // fiscal | diploma (quando documentType=xml)
  xmlPolicy: 'nfe-4.00', // opcional para XML
  certificateMode: 'auto', // auto | local | cloud
  documentContentBase64: pdfBase64,
  providerHint: 'birdid', // usado quando cloud
  providerCredentialId: 10, // preferencial quando cloud
  metadata: { source: 'prontuario' },
  requestOptions: { certificateId: 'abc' }, // usado no fluxo local
});

console.log(result.status);

Eventos de fluxo

  • flow:started
  • flow:awaiting_approval
  • flow:fallback_cloud
  • flow:signed
  • flow:failed
  • agent:not_found
const unsub = connector.on('flow:failed', (event) => {
  console.error('Falha de assinatura', event);
});

Erros

Todos os erros de SDK/API são SignerConnectorError:

try {
  await connector.sign(payload);
} catch (error) {
  if (error.name === 'SignerConnectorError') {
    console.error(error.code, error.message, error.recoverable, error.details);
  }
}

Recomendações para produção

  • Gere token Sanctum por account, com expiração curta.
  • Se usar local, mantenha Desktop Agent em http://127.0.0.1:9876.
  • Em cloud, trate estado pending_approval e faça polling com getStatus.
  • Baixe o arquivo assinado apenas quando status === 'signed'.
  • Envie metadata com document_id do parceiro para rastreabilidade.

Exemplos

  • examples/node-cloud-sign.mjs
  • examples/browser-cloud.html
  • examples/browser-local-agent.html

Executar exemplo Node com XML

SIGNER_API_BASE_URL="http://127.0.0.1:8000/api/v1" \
SIGNER_API_TOKEN="seu_token" \
SIGNER_PROVIDER_HINT="serproid" \
SIGNER_PROVIDER_CREDENTIAL_ID="12" \
SIGNER_DOCUMENT_TYPE="xml" \
SIGNER_XML_PROFILE="diploma" \
SIGNER_XML_POLICY="diploma-icpbrasil-xades-1.0" \
SIGNER_XML_PATH="/caminho/para/documento.xml" \
