tangram_core

tangram_core is the foundation of the tangram platform. It provides the essential scaffolding for custom geospatial visualisation tools.

While often used for aviation data, tangram_core itself is domain-agnostic. It handles the infrastructure (displaying maps, managing state, handling connections) so plugins can focus on the domain logic (decoding ADS-B, processing maritime signals, simulating weather).

• Repository: https://github.com/open-aviation/tangram

Components

• Backend: A Python application (FastAPI) that manages the lifecycle of plugins and background services.
• Channel: A high-performance Rust service that bridges Redis pub/sub with WebSockets for real-time frontend updates.
• Frontend: A Vue.js + Deck.gl shell that dynamically loads widgets and layers from installed plugins.

Usage

This package is rarely used alone. It is typically installed alongside plugins:

# with uv
uv tool install --with tangram-jet1090 --with tangram-system tangram-core
# with pip
pip install tangram-core tangram-jet1090 tangram-system
# launch!
tangram serve --config /path/to/your/tangram.toml
