Usage example

Define Protocol (Shared)

export interface ReqHello {
  name: string;

export interface ResHello {
  reply: string;

Implement API (Server)

import { ApiCall } from "tsrpc";

export async function ApiHello(call: ApiCall<ReqHello, ResHello>) {
    reply: 'Hello, ' + call.req.name

Call API (Client)

let ret = await client.callApi('Hello', {
    name: 'World'
