QRDM provides a python package, network API endpoints, and web interfaces for encoding and decoding documents as a series of QR codes.
The qrdm package is written in pure Python; the ease of installation is dependent on
availability of its dependencies.
The simplest method of installing the qrdm package is via pip.
pip install qrdmIf pip is able to reach a suitable package index, qrdm will install along with its
core Python dependencies.
IMPORTANT
The QR decoding functionality depends on the
pyzbarpython package, which in turn depends on thezbarshared library. This may require you to install thezbarpackage via your system's package manager. See thepyzbarinstallation instructions for more details.
Two main "package extras" are available for qrdm that provide REST API application
("backend") and Web application ("frontend") services for the QR encoding & decoding
functions. These can be included by specifying qrdm[backend] or
qrdm[frontend] to the installation command above, respectively.
A Streamlit "frontend" can be run via:
git clone https://github.com/mit-ll/qrdm
cd qrdm
python -m pip install .[frontend]
streamlit run ui/QRDM_Home.py --client.toolbarMode=viewerThis will host the app at http://localhost:8501 by default, with pages for QR encoding
and decoding. The host and port can be controlled by passing --server.port=XXXX and
--server.address=X.X.X.X, as per the syntax of the streamlit run command.
To run the "backend" FastAPI app via uvicorn, use uvicorn directly. For example:
python -m pip install qrdm[backend]
uvicorn qrdm.backend:app --host localhost --port 8182This will result in the app being hosted at http://localhost:8182. Swagger
documentation will be hosted at http://localhost:8182/docs, if an internet connection
is available. Further options are available via uvicorn command-line configuration.
