E-Invoice code lists needed in EN16931, ZUGFeRD and XRechnung for JavaScript / TypeScript

A convenient meta-package that bundles essential code lists for European e-invoicing standards like EN16931, ZUGFeRD, and XRechnung. It simplifies development by providing curated codes from various official sources in one place.

Why This Package?

When building applications that handle e-invoices, you often need several standardized code lists from different sources. Instead of installing and managing multiple individual packages, e-invoice-codes provides a single dependency for the most frequently required lists.

This package re-exports the latest, most common code lists from the following specialized packages, simplifying your project's dependency tree:

• electronic-address-scheme: Provides the Electronic Address Scheme (EAS) codes.
• un-ece-recommendation: Provides code lists for units of measure (Rec. 20) and packaging types (Rec. 21).
• untdid: Provides various code lists from the United Nations Trade Data Interchange Directory.

RechnungsAPI

If you are looking for an API solution to generate German e-invoice documents, consider checking out RechnungsAPI, without which this package would not exist.

Installation

Install the package using your favorite package manager:

npm install e-invoice-codes

or

yarn add e-invoice-codes

Usage

You can import all the necessary code lists directly from the e-invoice-codes package. The exports are aliased for clarity and convenience.

import {
  EAS,
  REC_20,
  REC_21,
  UNTDID_1001,
  UNTDID_5305
} from 'e-invoice-codes';

// Example: Get the latest Electronic Address Scheme codes
console.log('EAS Codes:', EAS);
// [
//   {
//   	code: "0002",
//   	name: "System Information et Repertoire des Entreprise et des Etablissements: SIRENE",
//   },
//   { code: "0007", name: "Organisationsnummer" },
//   { code: "0009", name: "SIRET-CODE" },
//   ...
// ]

// Example: Get UN/ECE Recommendation N°20 (Units of Measure)
console.log('Unit Codes:', REC_20);
// [
//   { code: "05", name: "lift" },
//   { code: "06", name: "small spray" },
//   { code: "08", name: "heat lot" },
//   ...
// ]

// Example: Get UNTDID 5305 (Tax category codes)
console.log('Tax Category Codes:', UNTDID_5305);
// [
//   {
//   	code: "A",
//   	name: "Mixed tax rate",
//   	description: "Code specifying that the rate is based on mixed tax.",
//   },
//   {
//   	code: "AA",
//   	name: "Lower rate",
//   	description: "Tax rate is lower than standard rate.",
//   },
//   ...
// ]
