@e-invoice-eu/server

This directory contains the source code of the E-Invoice-EU web service with a RESTful API. The service is written with NestJS.

Pre-requisites

• NodeJS 17 or newer (currently tested with NodeJS 18, 20, and 22)
• A package manager like npm, yarn, pnpm, bun ...

Installation

$ pnpm install

This may warn about "husky" missing. Just run pnpm install again in order to fix this.

If you do not like pnpm, replace it with npm, yarn, bun or whatever is currently hyped.

Running the app

# development
$ pnpm run start

# watch mode
$ pnpm run start:dev

# production mode
$ pnpm run start:prod

Test

# unit tests
$ pnpm run test

# e2e tests
$ pnpm run test:e2e

# test coverage
$ pnpm run test:cov

Running in a Container

By far the easiest way is to run the application in a software container.

Pull the Docker image:

$ docker pull gflohr/e-invoice-eu:latest

Run the container:

$ docker run -it --rm -d -p 3000:3000 --name e-invoice-eu gflohr/e-invoice-eu:latest

If you want to debug issues, omit the option -d so that you can see the output of the application running inside of the container.

Access the application from your host computer:

$ curl http://localhost:3000/api/format/list

Or you can see the OpenAPI/Swagger documentation:

curl http://localhost:3000/api

It probably makes more sense to open that URL in the browser.

See the documentation for information on how to create e-invoices with the API.

Run Slim Container

There is also a Docker image without LibreOffice. You can use that if:

• You do not plan to create e-invoices from spreadsheet data, or
• You always provide a PDF version for Factur-X/ZUGFeRD, and do not need to render the spreadsheet as a PDF

In this case, use the image gflohr/e-invoice-eu:slim instead of gflohr/e-invoice-eu:latest.
