Development environment

Prerequisites

• Git
• uv
• Docker (with Compose)
• just

Getting started

git clone https://github.com/4TUResearchData/djehuty.git
cd djehuty/

Running the development environment

To spin up a fully working local instance, run:

just dev

This builds and starts Docker containers for djehuty and Virtuoso (SPARQL store). On first run, the database is automatically initialized with categories, licences, and a dev account with full admin privileges — no extra setup needed.

Once running:

• Djehuty: http://localhost:8080 (auto-login, no auth setup needed)
• Virtuoso SPARQL: http://localhost:8890/sparql (useful for troubleshooting)

Edit any Python file under src/ and the server reloads automatically.

To stop and remove the development environment, run just clean. To see all available commands, run just --list.

Running in production

Djehuty needs a SPARQL 1.1 endpoint such as Virtuoso OSE or Jena Fuseki to store its state.

Copy the example configuration and adjust it for your environment:

cp etc/djehuty/djehuty-example-config.xml djehuty.xml

First run

Upon first run, djehuty needs to initialize the database with categories, licences and accounts. To do so, pass the --initialize option to the djehuty web command:

djehuty web --initialize --config-file djehuty.xml

Subsequent runs

After the database has been initialized, you can remove the --initialize option:

djehuty web --config-file=djehuty.xml
