IOTA Ruby Gem

GitHub license Gem Version

This is the unofficial Ruby gem for the IOTA Core. It implements both the official API, as well as newly proposed functionality (such as signing, bundles, utilities, conversion, multi signature support and reattch/promote).

Installation

Add this line to your application's Gemfile:

gem 'iota-ruby'

And then execute:

$ bundle

Or install it yourself as:

$ gem install iota-ruby

Getting Started

After you've successfully installed the library, it is fairly easy to get started by simply launching a new instance of the IOTA object with an optional settings object. When instantiating the object you have the option to decide the API provider that is used to send the requests to and you can also connect directly to the Sandbox environment.

The optional settings object can have the following values:

  1. host: String Host you want to connect to. Can be DNS, IPv4 or IPv6. Defaults to localhost
  2. port: Int port of the host you want to connect to. Defaults to 14265.
  3. provider: String If you don't provide host and port, you can supply the full provider value to connect to
  4. sandbox: Bool Optional value to determine if your provider is the IOTA Sandbox or not.
  5. token: String Token string in case you are using sandbox.

You can either supply the remote node directly via the provider option, or individually with host and port, as can be seen in the example below:

require 'iota'

# Create client with host and port as provider
client = IOTA::Client.new(host: 'http://localhost', port: 14265)

# Create client directly with provider
client = IOTA::Client.new(provider: 'http://localhost:14265')

# now you can start using all of the functions
status, data = client.api.getNodeInfo

Overall, there are currently four subclasses that are accessible from the IOTA object:

  • api: Core API functionality for interacting with the IOTA core.
  • utils: Utility related functions for conversions, validation and so on
  • validator: Validator functions that can help with determining whether the inputs or results that you get are valid.
  • multisig: Functions for creating and signing multi-signature addresses and transactions.

How to use the Library

All API calls are executed synchronously and returns array with 2 entries. First entry is status and second is data. However, you can use it by passing block to it as well.

Here is a simple example of how to access the getNodeInfo function:

# Method 1
client.api.getNodeInfo do |status, data|
  if !status
    # If status is `false`, `data` contains error message...
    puts data
  else
    # If status is `true`, `data` contains response...
    puts data.inspect
  end
end

# Method 2
status, data = client.api.getNodeInfo
if !status
  puts data
else
  puts data.inspect
end
