How to run the Ldraw Nova web app with Docker with Ldraw Nova

Start the browser app with 3D and VR views on localhost using Docker Compose.

Who it is forA builder who wants interactive 3D and VR views of models, including a Meta Quest 3 headset, on a trusted home network.

The problemViewing generated models in 3D and VR needs a running app and a matching set of repositories.

The outcomeThe web app running at localhost:8765, with HTTPS on port 8443 for VR, and conversation history available.

What you need first

  • Python 3.12 or newer
  • An installed LDraw parts library and the LDRAW_DIR path to it
  • Poppler (pdftotext) on PATH
  • LeoCAD on PATH
  • Git and Docker, only for the web app

Steps

  1. Install Git and Docker.
  2. Clone matching release tags side by side with git clone --branch v0.6.0 https://github.com/anteloc/ldraw-nova.git and git clone --branch v0.6.0 https://github.com/anteloc/ldraw-nova-docker.git.
  3. Change into the Docker repository with cd ldraw-nova-docker, then run docker compose build and docker compose up -d.
  4. Open http://localhost:8765, or https://localhost:8443 for VR on Meta Quest 3, and accept the self-signed certificate.
  5. Stop the app with docker compose down when finished.

Prompt for your agent

Clone the ldraw-nova and ldraw-nova-docker repositories at tag v0.6.0 side by side, then run docker compose build and docker compose up -d inside ldraw-nova-docker. Report the local URL and confirm that http://localhost:8765 responds before finishing.

Caveat. The app has no login and the README says to run it only on a trusted network, and the first Docker build needs about 5 GB of disk space.
