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 🙏

ksef-client

v0.2.0

Published

KSeF 2.0 client library for Node.js (TypeScript)

Readme

KSeF Client (TypeScript)

ksef-client-typescript jest repozytorium biblioteki (SDK) publikowanej na npm jako ksef-client.

✅ Funkcjonalności

Biblioteka udostępnia:

  • cienką warstwę klientów API mapującą metody na endpointy KSeF,
  • gotowe workflow do uwierzytelniania, sesji online/batch oraz eksportu,
  • usługi pomocnicze (XAdES, kryptografia, linki weryfikacyjne, QR, parser tokenów osób).

🔄 Kompatybilność API KSeF

Aktualna kompatybilność: KSeF API v2.1.2.

⚙️ Wymagania

  • Node.js >= 20
  • dostęp do środowiska KSeF (TEST, DEMO, PRD)
  • dane uwierzytelniające (token KSeF lub certyfikat/XAdES)

📦 Instalacja

npm install ksef-client

Opcjonalnie (w zależności od używanych funkcji):

npm install qrcode
npm install node-forge
  • qrcode jest wymagane przez QrCodeService (client.qr),
  • node-forge jest wymagane przez obsługę PKCS#12 w XadesKeyPair.fromPkcs12*.

📚 Dokumentacja

🧪 CI/CD

CI TypeScript E2E TEST token TypeScript E2E TEST cert TypeScript E2E DEMO token TypeScript E2E DEMO cert

Testy uruchamiane są lokalnie przez Node.js test runner (node --test) oraz w GitHub Actions.

Instalacja zależności testowych:

npm ci

Uruchomienie testów:

npm test

Uruchomienie testów z kontrolą pokrycia:

npm run test:coverage

Lokalna kontrola jakości (jak w CI):

npm run lint
npm run typecheck

Podstawowe workflow:

  • CI (.github/workflows/ci.yml) - lint, typecheck i testy.
  • E2E Auth Flows (.github/workflows/e2e-token.yml) - scenariusze token/XAdES dla TEST i DEMO.
  • Validate API Compliance (.github/workflows/validate-openapi.yml) - kontrola pokrycia endpointów.
  • Release Please (.github/workflows/release-please.yml) - automatyzacja wersjonowania.
  • Publish to npm (.github/workflows/publish-npm.yml) - publikacja paczki.

🚀 Quick start

Minimalny przebieg integracji:

  1. uwierzytelnienie (np. token KSeF),
  2. wywołanie endpointu biznesowego.
import { KsefClient } from "ksef-client";

const client = await KsefClient.connect({
  environment: "DEMO",
  token: process.env.KSEF_TOKEN!,
  context: { type: "Nip", value: "5265877635" },
  pollIntervalMs: 2000,
  maxAttempts: 60,
});

const metadata = await client.invoices.queryInvoiceMetadata(
  {
    subjectType: "Subject1",
    dateRange: {
      dateType: "Issue",
      from: "2025-01-01",
      to: "2025-01-31",
    },
  },
  0,
  10,
  "Desc",
);

console.log(metadata);

🧩 Najważniejsze snippety

Uwierzytelnianie tokenem KSeF (workflow)

import { KsefClient } from "ksef-client";

const client = new KsefClient({ environment: "DEMO" });

const tokens = await client.workflows.auth.authenticateWithKsefToken({
  token: process.env.KSEF_TOKEN!,
  context: { type: "Nip", value: "5265877635" },
  pollIntervalMs: 2000,
  maxAttempts: 60,
});

client.authManager.setTokens(tokens);

Uwierzytelnianie certyfikatem (XAdES)

import { KsefClient, XadesKeyPair } from "ksef-client";

const client = new KsefClient({ environment: "DEMO" });

const keyPair = await XadesKeyPair.fromPkcs12File({
  pkcs12Path: "./cert.p12",
  pkcs12Password: process.env.XADES_PASSWORD,
});

const tokens = await client.workflows.auth.authenticateWithCertificate({
  keyPair,
  context: { type: "Nip", value: "5265877635" },
  subjectIdentifierType: "certificateSubject",
  enforceXadesCompliance: true,
  pollIntervalMs: 2000,
  maxAttempts: 60,
});

client.authManager.setTokens(tokens);

Wysyłka faktury (sesja online)

const session = await client.workflows.sessions.online.open({
  formCode: { systemCode: "FA (3)", schemaVersion: "1-0E", value: "FA" },
  upoV43: true,
});

await session.sendInvoice({ invoice: "<Faktura>...</Faktura>" });
await session.close();

const upoXml = await session.waitForUpo({ pollIntervalMs: 2000, maxAttempts: 60 });
console.log(upoXml ? "UPO odebrane" : "Brak UPO w zadanym limicie prób");
