Appwrite的JavaScript SDK为什么能够让开发者轻松实现各种操作？

import { Account, Client, Databases, ID } from 'appwrite';

// 初始化客户端
const client = new Client();
client
  .setEndpoint('https://YOUR_ENDPOINT/v1') // 替换为你的Appwrite API端点
  .setProject('YOUR_PROJECT_ID'); // 替换为你的项目ID

// 创建账户和数据库服务实例
const account = new Account(client);
const databases = new Databases(client);

// 用户注册
const createUser = async (email, password, name) => {
  try {
    const user = await account.create(ID.unique(), email, password, name);
    console.log('User created:', user);
  } catch (error) {
    console.error('Error creating user:', error.message);
  }
};

// 用户登录
const loginUser = async (email, password) => {
  try {
    const user = await account.createEmailSession(email, password);
    console.log('User logged in:', user);
  } catch (error) {
    console.error('Error logging in:', error.message);
  }
};

// 数据库写入数据
await databases.createDocument(
    'marvel',
    'movies',
    ID.unique(),
    {
        title: 'Spiderman',
        year: 2002,
        reviews: [
            { 
                author: 'Bob', 
                text: 'Great movie!',
                $permissions: [
                    Permission.read(Role.any())
                ]
            },
        ]
    }
);

class AppwriteException extends Error {
    code: number;
    response: string;
    type: string;
    constructor(message: string, code: number = 0, type: string = '', response: string = '') {
        super(message);
        this.name = 'AppwriteException';
        this.message = message;
        this.code = code;
        this.type = type;
        this.response = response;
    }
}
