Zero-dependency, OOP HTTP / WebSocket / JSON-RPC client for TypeScript, built with native fetch and WebSocket only. Architecture is deliberately language-agnostic (Strategy, Chain of Responsibility, Adapter) so the same design ports to Go / Python later.

Usage

import { HttpClient } from './src';

const api = new HttpClient({ baseURL: 'https://api.example.com', timeout: 5000 });

api.interceptors.request.use((config) => {
  config.headers = { ...config.headers, Authorization: 'Bearer token' };
  return config;
});

const { data } = await api.get('/users/1');

import { WebSocketClient, JsonRpcClient } from './src';

const ws = new WebSocketClient('wss://api.example.com/ws');
ws.connect();
const rpc = new JsonRpcClient(ws);
const result = await rpc.call('getUser', { id: 1 });

Structure

src/
  core/       RequestConfig, Response, errors, InterceptorManager (Chain of Responsibility)
  transport/  Transport interface (Strategy) + FetchTransport
  http/       HttpClient (axios-style API)
  ws/         WebSocketClient (native WS + backoff reconnect)
  rpc/        JsonRpcClient (JSON-RPC 2.0, Adapter over HTTP or WS)
  utils/      QueryString helpers

Roadmap

• Node http/https transport (no fetch dependency for older runtimes)
• GraphQL client (Adapter over HttpClient, same interceptor pipeline)
• Retry policy plugin (Strategy, composes with Transport)
