VoxVera Flyers

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

macOS

With Homebrew you can install the same dependencies:

brew install jq qrencode imagemagick poppler node coreutils

These scripts rely on the GNU implementation of mktemp (gmktemp) found in coreutils. If you prefer not to install coreutils, edit the scripts to use mktemp without the --suffix option.

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.

Windows

These scripts rely on a Unix-like environment. The recommended approach on Windows is to use WSL2 with a Debian distribution. Install WSL and Debian with:

wsl --install

Launch the Debian terminal and run setup.sh from this repository or the apt commands shown above to install all prerequisites. Alternative environments such as MSYS2 or Git Bash can also be used, but they must provide the same command-line utilities.

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.
