Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

wx-link

wx-link 是一个基于 TypeScript 的 iLink stateless core SDK,聚焦扫码登录、消息轮询、文本/媒体发送,以及入站媒体解析、下载和解密。

它只负责协议调用,不负责保存业务状态。tokenbaseUrlcursor、会话和聊天记录都需要由你的应用自己保存。

通过微信的 ClawBot 实现微信自定义机器人的接入能力。

安装

npm i wx-link

文档

在线文档

Quick Start

import { loginWithQR, WxLinkClient } from "wx-link";

const login = await loginWithQR({
  onQRCode: (url) => console.log("Scan QR:", url),
});

const client = new WxLinkClient({
  baseUrl: login.baseUrl,
  token: login.botToken,
});

let cursor = "";

while (true) {
  const updates = await client.poll(cursor);
  cursor = updates.nextCursor;

  for (const msg of updates.msgs ?? []) {
    if (!msg.from_user_id) {
      continue;
    }

    await client.sendText({
      toUserId: msg.from_user_id,
      text: "hello",
      contextToken: msg.context_token,
    });
  }
}

重要限制

  1. 这套能力依赖 iLink 私有 HTTP / CDN 协议,不是微信官方公开 SDK。
  2. toUserId 需要业务方自己掌握。
  3. contextToken 在“回复已有会话”时最稳妥;没有它时是否允许首次主动发消息,要以实际环境验证为准。
  4. 收到的图片或文件通常是 CDN 密文,浏览器不能直接显示,通常需要先走 SDK 下载并解密。
  5. token、cursor、会话和聊天记录需要由业务方自己管理,生产环境建议放到数据库、KMS 或密钥托管方案里。
