MQTT OpenFaas Bridge

Run async OpenFaas functions and receive results back via MQTT.

To run a function, publish a message
on the topic openfaas/invoke/function-name with a JSON payload.

{
    "input": "input for openfaas function",
    // Callback parameters will be passed through to the response
    "callbackParams": {
        "url-encoded": "additional-info"
    }
}

You can then listen for results on the openfaas/results/function-name topic.

{
    "output": "output from the function",
    "params": {
        "params": "are passed through"
    }
}

You can configure the bridge by setting environmental variables manually or in a .env file. They’re currently documented in the .env.example file.
