DVM Reference Implementation

This is a reference implementation of a DVM (Data Vending Machine) backend.

Properties

• Segregated identities per DVM
• Modular DVMs -- each DVM is instantiated in it's own module

Modules

DVMs are just modules that export a register function. This function is called upon instantiation of the DVM.

Within the module, the DVM should register handlers for the different kinds it wants to support.

Here is a demo DVM that would say Hello World when it's tagged in a request

// config.json
{
    "dvms": {
        "You might have missed": {
            "module": "dvms/hello-world.js",
            "key": "<private-key-in-hex>",
            "requireTagging": true,
            "kinds": {
                "65100": {
                }
            }
        }
    }
}

// hello-world.ts
export async function register(dvm: DVM): Promise<void> {
    dvm.d("registering DVM", dvm.name);

    const sayHello = async (request: NDKDVMRequestExtended) => {
        request.processing(`I am processing your request job`);

        const response = new NDKDVMJobResult();

        response.content = "Hello World!";

        return response;
    };

    dvm.handlers[65100].push(sayHello);
}
