Installation

Install the SDK using pnpm or yarn:

pnpm add @nuecms/weapp-sdk
# or
yarn add @nuecms/weapp-sdk

---

Quick Start

1. Import and Initialize the SDK Builder

import { wxSdk } from '@nuecms/weapp-sdk';

const sdk = wxSdk({
  appId: string;
  appSecret: string;
  cacheProvider: CacheProvider;
});

2. Register API Endpoints

sdk.r('getUser', '/users/{id}', 'GET');
sdk.r('createUser', '/users', 'POST');

3. Make API Calls

const user = await sdk.getUser({ id: '12345' });
console.log(user);

4. Signature with API calls

const sdk = wxSdk({
  appId: string;
  appSecret: string;
  cacheProvider: CacheProvider;
  signature: {
    symKey: string; // 对称密钥
    symSn: string; // 对称密钥编号
    privateSn: string; // 私钥编号
    privateKey: string; // 私钥
    certificate: string; // 开放平台证书
  } // default false
});

Usage Examples

Registering Endpoints

Register endpoints with their HTTP method, path, and dynamic placeholders (e.g., {id}):

sdk.r('getUser', '/users/{id}', 'GET');
sdk.r('deleteUser', '/users/{id}', 'DELETE');
sdk.r('createUser', '/users', 'POST');

Making API Calls

Call the registered endpoints dynamically with placeholders and additional options:

const userDetails = await sdk.getUser({ id: '12345' });

console.log(userDetails);
