The Command invoice

The command invoice takes the following options and arguments:

Name	Argument	Description
-f, --format	string	a supported format
-o, --output	string	write output to specified file instead of standard output
-i, --invoice	string	JSON file with invoice data, mandatory for invoice generation from JSON
-m, --mapping	string	YAML or JSON file with mapping, mandatory for invoice generation from spreadsheet data
-d, --data	string	invoice spreadsheet file, mandataory for invoice generation from spreadsheet data
-l, --lang	string	a language identifier like fr-fr
--embedPDF		use if a PDF version should be embedded into XML output
-p, --pdf	string	a PDF version of the invoice
--pdf-id	string	ID of the embedded PDF, defaults to the document number; ignored for Factur-X/ZUGFeRD
--pdf-description	string	optional description of the embedded PDF; ignored for Factur-X/ZUGFeRD
-a, --attachment	string	optional name of an additional attachment
--attachment-id	string

Argument format

This contains the format of the e-invoice as a case-insensitive string. You can also use aliases. For example, Factur-X-Comfort is an alias for Factur-X-EN16931.

Argument lang

A language identifier like fr-fr. This is only used for the Factur-X/ZUGFeRD formats for some canned texts in the PDF XMP meta data.

Argument embedPDF

This is only used for the pure XML formats (everything that is not Factur-X/ZUGFeRD). If it has a truthy value, a PDF version of the invoice is embedded as a base64 encoded string in the XML.

Argument pdf

This is required in two cases:

1. The format is a Factur-X/ZUGFeRD format and data was not specified.
2. The format is a pure XML format, embedPDF was specified and data was not specified.

Argument data

A spreadsheet version of the invoice. If a PDF is required, either because embedPDF was specified for pure XML or because the format is Factur-X/ZUGFeRD, LibreOffice is invoked for rendering the spreadsheet as a PDF.

This feature will trigger an exception if used in the browser.

Argument attachments

You can specify an arbitrary number of additional attachments.

In case of the pure XML formats, they are embedded as base64 encoded strings in the XML. In case of Factur-X/ZUGFeRD they are attached to the PDF, additionally to the mandatory attachment factur-x.xml.

Getting Supported Formats

import { FormatFactoryService } from '@e-invoice-eu/core';

const factoryService = new FormatFactoryService();
const formats = factoryService.listFormatServices();

In format you will find an array of FormatInfo objects.

Getting the JSON Schema Definitions

import { invoiceSchema, mappingSchema } from '@e-invoice-eu/core';

These variables contain the schema for the Invoice and Mapping interfaces. These schemas can be passed as an argument to the compile method of an Ajv instance, see https://ajv.js.org/api.html#ajv-compile-schema-object-data-any-boolean-promise-any for more information!

The schemas have the type JSONSchemaType<Invoice> and JSONSchemaType<Mapping> respectively.
