VoxVera provides scripts and templates for producing printable flyers with QR codes. These flyers link to content hosted through Tor and can also include a Nostr page. The project automates building the HTML, generating the QR codes, and copying all assets into a directory under host/ so they can be served statically.

Prerequisites

Node.js and npm
jq
qrencode
ImageMagick (convert)
javascript-obfuscator and html-minifier-terser (installed via npm)
pdftotext (optional, used when extracting fields from a PDF form)

Installing Dependencies

On Debian or Ubuntu systems you can install the required packages with:

sudo apt update
sudo apt install -y jq qrencode imagemagick poppler-utils nodejs npm

The obfuscation scripts also rely on a pair of Node modules. Install them globally:

npm install -g javascript-obfuscator html-minifier-terser

A helper script setup.sh is provided to check for these dependencies and install anything that is missing.

Generating a Flyer

Run the helper script from the repository root:

# interactive prompts
./src/create_flyer.sh

# use answers from an existing PDF form
./src/create_flyer.sh --from-pdf path/to/form.pdf

The script updates src/config.json, regenerates QR codes, obfuscates index-master.html and nostr-master.html, and copies the resulting files plus PDFs and QR images into host/<subdomain>. The contents in that directory can then be hosted.

Additional documentation is available in the src/ directory; see src/README.md for more details on the obfuscation scripts and additional usage notes.

Step-by-Step

Edit src/index-master.html or src/nostr-master.html if you need custom content.
Run ./src/create_flyer.sh and follow the prompts, or use ./src/create_flyer.sh --from-pdf path/to/form.pdf.
Host the generated host/<subdomain> directory. This project is licensed under the MIT License.
