stagedings

An API to navigate scenes and subscenes that has been configured in a mididings script

---

What does stagedings allow?

• A web-based interface
  • Alternative of the legacy livedings UI, which was based on Tkinter 🪓
• A HTTP layer that facilitates control and navigation allowing the abstraction of OSC subcalls
• An OpenAPI specification making possible to generate a client SDK in multiple language with a code generator like Kiota making possible to use the API in .NET, Go, Java, PHP, Python, Ruby and TypeScript.

⚠️ A scene patch dictionary defined in the run section of your mididings script is required to work correctly, check the run function documentation for more information on how to structure your patch.

$ stagedings

This runs everything locally on:

http://localhost:5000 by default

Network / multi-client setup

When clients access the server from other machines, you must expose the backend:

$ stagedings --host 0.0.0.0

or:

$ stagedings --host 192.168.1.100

Sandbox setup (for debugging)

$ python scripts/run_cli.py [--host HOST] [--port PORT]

This runs everything locally on:

http://localhost:5000 by default

Accessing the UI

Once running, open in a browser:

http://your-hostname:5000

or:

http://192.168.1.100:5000
