YunGouOS Payment SDK: Installation, Usage, and New Features

YunGouOS is an open‑source payment SDK based on the official service provider model of WeChat and Alipay, handling account signing and direct settlement with the official platforms.

It integrates WeChat QR code, JSAPI, Mini‑Program payments, order queries, refunds, as well as Alipay QR, WAP, order queries, and refunds, allowing developers to connect with a single package.

Installation (recommended via npm): npm i yungouos-pay-sdk Import the SDK in your project: import { WxPay } from 'yungouos-pay-sdk'; Usage examples:

Synchronous QR code payment:

let result = WxPay.nativePayAsync(out_trade_no, total_fee, mch_id, body, type, attach, notify_url, auto, auto_node, config_no, payKey);
console.log(result);

Asynchronous QR code payment:

WxPay.nativePay(out_trade_no, total_fee, mch_id, body, type, attach, notify_url, auto, auto_node, config_no, payKey)
    .then(response => {
        console.log(response);
    });

The latest release adds a full JavaScript SDK supporting ten interfaces, including WeChat QR code payment, card payment, face payment, public account payment, cashier payment, H5 payment, APP payment, refund initiation, refund query, and billing statements, all with synchronous and asynchronous calls.

Planned next version features include completing Alipay interface integration, adding WeChat profit‑sharing APIs, and enhancing order API support.
