nano-stream-mqtt

A tiny and performant client that streams block data from a Nano currency node over the MQTT messaging protocol.

It builds on the socket stream of block data set up by the nano-stream-x library.

Installation

Install both nano-stream-x and nano-stream-mqtt as global packages:

npm install --global nano-stream-x
npm install --global nano-stream-mqtt

Usage

Start the stream

nano-stream-x

This will start a streaming server on 127.0.0.1:3000. To override these:

nano-stream-x host=ip6-localhost port=3001

Start the MQTT client

nano-stream-mqtt

By default you will connect to mqtt://127.0.0.1. To connect to a different host:

nano-stream-mqtt host=mqtts://mosquitto.example.com

Data will be sent to the default topic nanostream. To set a different topic:

nano-stream-mqtt topic=my_topic

To connect with a username and password:

nano-stream-mqtt username=my_username password=my_password

Configure your Nano node to send data to nano-stream-x

Your Nano node is easily configured to send block processing data to a server (in this case nano-stream-x). See the wiki article (external link) for how to set this up.
