Synternet Data Layer SDK

Welcome to the Data Layer SDK documentation. This SDK enables seamless integration with our Data Layer solution, allowing you to harness the power of real-time data streams in your Golang applications.

data-layer-sdk is a Golang library designed specifically for the Synternet Data Layer project. Powered by the NATS messaging system, data-layer-sdk abstracts away most of the intricate details of interacting with the Data Layer Broker network and the Blockchain to offer seamless integration between your Golang applications and the Synternet Data Layer platform.

Features

• Subscribe to Existing Data Streams: Easily subscribe to pre-existing data streams within the Synternet Data Layer. Receive real-time updates and harness the power of real-time data insights in your Golang applications.

• Publish New Data Streams: Create and publish your own data streams directly from your Golang applications. Share data with other participants in the Data Layer, facilitating collaboration and enabling the creation of innovative data-driven solutions.

• Support for JSON Messages: Leverage the flexibility and interoperability of JSON messages. data-layer-sdk provides support for handling JSON data, making it easy to work with complex data structures and seamlessly integrate with other systems and platforms. Even more, the SDK allows adding your own type marshallers to support any wire data format.

• Customizable Connection Options: Tailor the connection options to suit your specific needs. Configure parameters such as connection timeouts, retry mechanisms, and authentication details to ensure a secure and reliable connection to the Synternet Data Layer platform.

Installation

To install the SDK for Data Layer, you can use Go modules or include it as a dependency in your project. Here's an example of how to add it to your project:

go get github.com/synternet/data-layer-sdk

Make sure to import the package in your code:

import "github.com/synternet/data-layer-sdk"

Getting started

In order to implement a simple publisher, you may want to embed service.Service into your publisher's struct. Then in the constructor call Service.Configure that will use options to configure the publisher. After that it is as simple as running Start on your publisher.

The minimal example is as follows:

type Publisher struct {
	*service.Service
}

// Define custom payload messages
type MyMessage struct {
	RequestWas []byte `json:"request"`
}

func New(o ...options.Option) (*Publisher, error) {
	ret := &Publisher{
		Service: &service.Service{},
	}

	err := ret.Service.Configure(o...)
	if err != nil {
		return nil, fmt.Errorf("failed configuring the publisher: %w", err)
	}

	return ret, nil
}

func (p *Publisher) Start() <-chan error {
	err := p.subscribe()
	if err != nil {
		go func() {
			p.ErrCh <- err
		}()
		return p.ErrCh
	}

	return p.Service.Start()
}

func (p *Publisher) subscribe() error {
  // Do any necessary subscriptions
	return nil
}
