EpicChain EdgeJS API

Overview

EpicChain-EdgeJS-API is an advanced integration framework that connects EpicChain's blockchain functionalities with Node.js applications using Edge.js. This repository enables smooth execution of C# code from within a Node.js environment, allowing developers to leverage EpicChain's blockchain capabilities and integrate them with various external systems and services.

Key Features

• Node.js and .NET Integration: Seamlessly execute C# code from Node.js applications.
• Flexible API Layer: Interact with EpicChain’s smart contracts and services via a structured API.
• Cross-Platform Compatibility: Operates on any platform where Node.js and .NET Core are supported.

Configuration

To utilize the API effectively, you'll need to set up configuration parameters for Edge.js and EpicChain. Ensure you have the following environment variables and configuration settings in place:

• EPICCHAIN_API_URL: Specifies the URL endpoint for the EpicChain API. This should point to the location where your EpicChain services are hosted.
• EDGE_NET_DLL_PATH: The path to the .NET assembly (.dll) that Edge.js will utilize. This assembly contains the C# methods you want to call from Node.js.

Here’s an example .env configuration file:

EPICCHAIN_API_URL=http://localhost:5000/api
EDGE_NET_DLL_PATH=./path/to/your/csharp/assembly.dll

Usage

The EpicChain-EdgeJS-API provides a range of functionalities to interact with EpicChain. Below, you'll find detailed examples demonstrating how to utilize the API for various operations.

Basic Setup

Initialize Edge.js to integrate with your C# assembly:

const edge = require('edge');

const epicChainApi = edge.func({
  assemblyFile: process.env.EDGE_NET_DLL_PATH,
  typeName: 'EpicChainApi',
  methodName: 'CallMethod'
});

In the configuration above:

• assemblyFile points to the .NET DLL file.
• typeName specifies the C# class containing the methods you wish to call.
• methodName indicates the method in the C# class to be invoked.

Example 1: Querying EpicChain Data

To query data from EpicChain, you can call a method in your C# assembly as follows:

epicChainApi('QueryEpicChainData', { queryParam: 'value' }, (error, result) => {
  if (error) {
    console.error('Error:', error);
  } else {
    console.log('Data:', result);
  }
});

In this example:

• 'QueryEpicChainData' is the method in your C# assembly.
• { queryParam: 'value' } is the object containing parameters required by the C# method.
• The callback function handles the result or error.

Example 2: Submitting Transactions

For submitting transactions to the EpicChain network:

epicChainApi('SubmitTransaction', { transactionData: 'data' }, (error, result) => {
  if (error) {
    console.error('Transaction Error:', error);
  } else {
    console.log('Transaction Result:', result);
  }
});

In this example:

• 'SubmitTransaction' is a method in the C# assembly designed to handle transaction submissions.
• { transactionData: 'data' } includes the transaction details to be sent.

Example 3: Handling Responses

To handle and process responses from EpicChain:

epicChainApi('HandleResponse', { responseId: '123' }, (error, result) => {
  if (error) {
    console.error('Response Handling Error:', error);
  } else {
    console.log('Processed Response:', result);
  }
});

Here:

• 'HandleResponse' is a method that processes responses received from EpicChain.
• { responseId: '123' } represents the ID or data associated with the response.
