You can read every line. ## **Why we do it** Laws should be easy to comply with. Mandatory e-invoicing and the EU food information regulation affect thousands of businesses, yet the JavaScript world had no usable free libraries for them. So we build them ourselves and make them available to everyone. Our clients benefit twice: from technology we understand in detail, and from code that many eyes review. And you see how we work before you hire us. No reference letter is as honest as public source code. - ## **jasyPDF**In production PDFs and e-invoices (ZUGFeRD / Factur-X, XRechnung) in pure TypeScript, without a browser and without Java. [On GitHub](https://github.com/Flo0806/jasy-pdf) - ## **lmiv**In development Food information according to EU Regulation 1169/2011: derive ingredient lists, allergens and nutrition values correctly from recipes. [On GitHub](https://github.com/Flo0806/lmiv) - ## **nuxt-pigeon**Released Send and receive messages via Telegram, Discord, Slack, ntfy, Mastodon, Bluesky and webhooks, with one interface in Nuxt. [On GitHub](https://github.com/Flo0806/nuxt-pigeon) [Documentation](https://pigeon.fh-softdev.de) - ## **nuxt-freeform**Released Desktop-like drag and drop for Nuxt and Vue: lasso selection, multi-select, lists and free canvases.
