Introduction

Proposed solution for the package fragmentation across different package and application that used a basic package like building blocks.

How to use

How to use LogManager

We provide a logging manager that you can use in the following way

import "package:cln_common/cln_common.dart";

void main() {
  LogManager.getInstance.debug("This is an awesome debug print");
}

How to implement your own LightningClient

You can implement your own client that follow the rules of the cln.dart package with the following basic class

/// Client interface to create a core lightning client
/// That can support different protocols.
abstract class LightningClient {
  // Connect interface to initialize the client
  // with the correct protocol.
  LightningClient connect(String url);

  Future<T> call<R extends Serializable, T>(
      {required String method, required R params, T Function(Map)? onDecode});

  // Generic method to call a method in core lightning
  Future<Map<String, dynamic>> simpleCall(String method,
      {Map<String, dynamic> params = const {}});

  void close();
}

In order to use our powerful client method call we input request need to follow the class rules

abstract class Serializable {
  Map<String, dynamic> toJSON();

  T as<T>() => this as T;
}

How to create a valid JSON RPC 2.0

If you need to send you a JSON RPC 2.0 PRC 2.0 request or response you can use the following class

import "package:cln_common/cln_common.dart";

void main() {
  var request = Request(id: 12, method: "method_name", params: {});
  LogManager.getInstance.info("JSON 2.0 request ${request.toJson()}");
  // you can build this map from a JSON string with dart built in tools
  var responseStr = { 
    "id": 12,
    "jsonrpc": "22",
    "result": {}
  };
  var response = Response.fromJson(responseStr);
  LogManager.getInstance.info("JSON 2.0 response ${response.toJson()}");
}
