nano-stream-amqp v0.1.1

nano-stream-amqp

A tiny and performant client that streams block data from a Nano currency node to an AMQP exchange for use in things like RabbitMQ.

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-amqp as global packages:

npm install --global nano-stream-x
npm install --global nano-stream-amqp

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 AMQP client

nano-stream-amqp

By default you will connect to amqp://guest:guest@localhost:5672. This URL includes authentication for your AMQP server in the format amqp://<username>:<password>@<host>:<port>. To connect to a different host, or with different credentials:

nano-stream-amqp host=amqp://my_user:my_pass@localhost:5672

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

nano-stream-amqp exchange=my_exchange

To set a routing key:

nano-stream-amqp routing_key=my_routing_key

Set a number of publishing options like immediate, headers and many more through the publishing_opts argument as a stringified JSON value. See the node-ampq docs for full options.

nano-stream-amqp publishing_opts='{"mandatory":true}'

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.
