This web app allows you to write German business letters according to the DIN 5008 standard (Form A) using web browser only.
Simply copy all files to another server (adjust the paths and the app URL in manifest.json and worker.js in this case), or simply use the default instance.
Open the URL of the app and install it. Use the button Print to print the letter to paper or
to PDF file, and the Share button to share the letter as URL. To open a letter with a pre-written text simply share that text with the app.
