Lenny

Lenny is a free, open source Lending System for Libraries.

Technologies

• docker for deployment and containerization
• nginx handles patron requests (reverse proxy to app)
• FastAPI (python) as the web & API microframework
• Minio API for storing digital assets (Amazon, Internet Archive, or local flat-file)
• yaml for configuring library-level rules
• postgres for the database
• SQLAlchemy for the database python ORM
• Readium LCP for DRM; see LCP Server
• Readium Web SDK for a secure web reading experience
• OPDS RSS-like standard for syndicating holdings

Endpoints

• /v{1}/api
• /v{1}/manage
• /v{1}/read
• /v{1}/opds
• /v{1}/stats

Installation

docker/configure.sh  # generates lenny.env
docker compose -p lenny up -d --build

Navigate to localhost:8080 or whatever $LENNY_PORT you specified in your lenny.env

You may enter the API container via:

docker exec -it lenny_api bash

Rebuilding

docker compose -p lenny down
docker compose -p lenny up -d --build

Pilot

We're seeking partnerships with libraries who would like to try lending digital resources to their patrons.
