sample

server side

import { JsonRpcUtil } from "@kkito/jsonrpc";

const disp = JsonRpcUtil.getDispatcher();
disp.add("add", (a, b) => a + b);
const result = JsonRpcUtil.handle({
  id: 1,
  method: "add",
  version: "2.0",
  params: [3, 4],
});

// { jsonrpc: '2.0', id: 1, result: 7 }
console.log(result);

// deal with async
const asyncResult = JsonRpcUtil.asyncHandle({
  id: 1,
  method: "asyncAdd",
  version: "2.0",
  params: [3, 4],
});
// { jsonrpc: '2.0', id: 1, result: 7 }
console.log(asyncResult);

client side

import axios from "axios";

const proxy = RpcClient.build({
  request: async (jsonReq) => {
    return axios.post("/the_endpoint", jsonReq);
  },
});

const result = await proxy.add(3, 4);
