ezdvm 0.1.1

A simple python Data Vending Machine (DVM) implementation on nostr

ezdvm

Easily run any python code behind a DVM on Nostr. Just pick a kind (for basic text-to-text use 5050) and put the code you want to run in the do_work() function. Then run the DVM.

Install

cd ezdvm/
python3.12 -m venv venv
source venv/bin/activate
pip install ezdvm

Create your own DVM

Steps:

1. Choose the job request kind in the init function
2. Run any python code inside the do_work() function. The event arg is the original job request from the user, in the form of nostr-sdk event, for python examples see here: https://github.com/rust-nostr/nostr/tree/master/bindings/nostr-sdk-ffi/bindings-python/examples

from ezdvm import EZDVM


class HelloWorldDVM(EZDVM):

    def __init__(self):
        # choose the job request kinds you will listen and respond to
        super().__init__(kinds=[5050])

    async def do_work(self, event):
        return "Hello World!"


if __name__ == "__main__":
    hello_world_dvm = HelloWorldDVM()
    hello_world_dvm.add_relay("wss://relay.damus.io")
    hello_world_dvm.add_relay("wss://relay.primal.net")
    hello_world_dvm.add_relay("wss://nos.lol")
    hello_world_dvm.add_relay("wss://nostr-pub.wellorder.net")
    hello_world_dvm.start()

Testing

Once it's running on your machine, if you are using kind 5050 you can test it here: https://dvmdash.live/playground/
