Instructions

操作步骤

Step 1: Implement Singleton Pattern (Recommended)

步骤1：实现单例模式（推荐）

typescript

// src/instantly/client.ts
import { InstantlyClient } from '@instantly/sdk';

let instance: InstantlyClient | null = null;

export function getInstantlyClient(): InstantlyClient {
  if (!instance) {
    instance = new InstantlyClient({
      apiKey: process.env.INSTANTLY_API_KEY!,
      // Additional options
    });
  }
  return instance;
}

typescript

// src/instantly/client.ts
import { InstantlyClient } from '@instantly/sdk';

let instance: InstantlyClient | null = null;

export function getInstantlyClient(): InstantlyClient {
  if (!instance) {
    instance = new InstantlyClient({
      apiKey: process.env.INSTANTLY_API_KEY!,
      // Additional options
    });
  }
  return instance;
}

Step 2: Add Error Handling Wrapper

步骤2：添加错误处理包装器

typescript

import { InstantlyError } from '@instantly/sdk';

async function safeInstantlyCall<T>(
  operation: () => Promise<T>
): Promise<{ data: T | null; error: Error | null }> {
  try {
    const data = await operation();
    return { data, error: null };
  } catch (err) {
    if (err instanceof InstantlyError) {
      console.error({
        code: err.code,
        message: err.message,
      });
    }
    return { data: null, error: err as Error };
  }
}

typescript

import { InstantlyError } from '@instantly/sdk';

async function safeInstantlyCall<T>(
  operation: () => Promise<T>
): Promise<{ data: T | null; error: Error | null }> {
  try {
    const data = await operation();
    return { data, error: null };
  } catch (err) {
    if (err instanceof InstantlyError) {
      console.error({
        code: err.code,
        message: err.message,
      });
    }
    return { data: null, error: err as Error };
  }
}

Step 3: Implement Retry Logic

步骤3：实现重试逻辑

typescript

async function withRetry<T>(
  operation: () => Promise<T>,
  maxRetries = 3,
  backoffMs = 1000
): Promise<T> {
  for (let attempt = 1; attempt <= maxRetries; attempt++) {
    try {
      return await operation();
    } catch (err) {
      if (attempt === maxRetries) throw err;
      const delay = backoffMs * Math.pow(2, attempt - 1);
      await new Promise(r => setTimeout(r, delay));
    }
  }
  throw new Error('Unreachable');
}

typescript

async function withRetry<T>(
  operation: () => Promise<T>,
  maxRetries = 3,
  backoffMs = 1000
): Promise<T> {
  for (let attempt = 1; attempt <= maxRetries; attempt++) {
    try {
      return await operation();
    } catch (err) {
      if (attempt === maxRetries) throw err;
      const delay = backoffMs * Math.pow(2, attempt - 1);
      await new Promise(r => setTimeout(r, delay));
    }
  }
  throw new Error('Unreachable');
}

Output

输出结果

Type-safe client singleton
Robust error handling with structured logging
Automatic retry with exponential backoff
Runtime validation for API responses

类型安全的客户端单例
带结构化日志的健壮错误处理
带指数退避的自动重试
API响应的运行时验证

Error Handling

错误处理

Pattern	Use Case	Benefit
Safe wrapper	All API calls	Prevents uncaught exceptions
Retry logic	Transient failures	Improves reliability
Type guards	Response validation	Catches API changes
Logging	All operations	Debugging and monitoring

模式	适用场景	优势
安全包装器	所有API调用	防止未捕获异常
重试逻辑	临时故障	提升可靠性
类型守卫	响应验证	捕获API变更
日志记录	所有操作	调试与监控

Examples

示例

Factory Pattern (Multi-tenant)

工厂模式（多租户）

typescript

const clients = new Map<string, InstantlyClient>();

export function getClientForTenant(tenantId: string): InstantlyClient {
  if (!clients.has(tenantId)) {
    const apiKey = getTenantApiKey(tenantId);
    clients.set(tenantId, new InstantlyClient({ apiKey }));
  }
  return clients.get(tenantId)!;
}

typescript

const clients = new Map<string, InstantlyClient>();

export function getClientForTenant(tenantId: string): InstantlyClient {
  if (!clients.has(tenantId)) {
    const apiKey = getTenantApiKey(tenantId);
    clients.set(tenantId, new InstantlyClient({ apiKey }));
  }
  return clients.get(tenantId)!;
}

Python Context Manager

Python 上下文管理器

python

from contextlib import asynccontextmanager
from instantly import InstantlyClient

@asynccontextmanager
async def get_instantly_client():
    client = InstantlyClient()
    try:
        yield client
    finally:
        await client.close()

python

from contextlib import asynccontextmanager
from instantly import InstantlyClient

@asynccontextmanager
async def get_instantly_client():
    client = InstantlyClient()
    try:
        yield client
    finally:
        await client.close()

Zod Validation

Zod 验证

typescript

import { z } from 'zod';

const instantlyResponseSchema = z.object({
  id: z.string(),
  status: z.enum(['active', 'inactive']),
  createdAt: z.string().datetime(),
});

typescript

import { z } from 'zod';

const instantlyResponseSchema = z.object({
  id: z.string(),
  status: z.enum(['active', 'inactive']),
  createdAt: z.string().datetime(),
});
