Taiwan SMS Adapters

This skill provides comprehensive guidance for using @rytass/sms-adapter-* packages to integrate Taiwan SMS service providers.

Overview

All adapters implement the SMSService interface from @rytass/sms , providing a unified API across different providers:

Package Provider Description

@rytass/sms-adapter-every8d

Every8D (每日簡訊 / 互動資通) Taiwan SMS gateway by Interactive Communications

Base Interface (@rytass/sms)

All adapters share these core concepts:

SMSService - Main interface for SMS operations:

interface SMSService< Request extends SMSRequest, SendResponse extends SMSSendResponse, MultiTarget extends MultiTargetRequest,

{ send(request: Request[]): Promise<SendResponse[]>; send(request: Request): Promise<SendResponse>; send(request: MultiTarget): Promise<SendResponse[]>; }

Request Types:

SMSRequest
Single SMS message to one recipient
MultiTargetRequest
Same message to multiple recipients

Response Status:

SUCCESS
Message sent successfully
FAILED
Message delivery failed

Taiwan Phone Number Helpers (from @rytass/sms ):

// 台灣手機號碼正規表達式 const TAIWAN_PHONE_NUMBER_RE = /^(0|+?886-?)9\d{2}-?\d{3}-?\d{3}$/;

// 正規化台灣手機號碼（移除非數字字元，將 886 前綴轉為 0） function normalizedTaiwanMobilePhoneNumber(mobile: string): string; // '0987-654-321' → '0987654321' // '+886987654321' → '0987654321' // '886987654321' → '0987654321'

Installation

Install base package

npm install @rytass/sms

Choose the adapter for your provider

npm install @rytass/sms-adapter-every8d

Quick Start

Every8D (每日簡訊 / 互動資通)

import { SMSServiceEvery8D } from '@rytass/sms-adapter-every8d';

// Initialize SMS service const smsService = new SMSServiceEvery8D({ username: process.env.EVERY8D_USERNAME!, password: process.env.EVERY8D_PASSWORD!, baseUrl: 'https://api.e8d.tw', // Default API endpoint onlyTaiwanMobileNumber: true, // Restrict to Taiwan numbers only });

// Send single SMS const result = await smsService.send({ mobile: '0987654321', text: 'Hello! This is a test message.', });

console.log('Message ID:', result.messageId); console.log('Status:', result.status); console.log('Mobile:', result.mobile);

Common Usage Patterns

Single SMS Delivery

Send a message to a single recipient:

// Basic single SMS const result = await smsService.send({ mobile: '0987654321', text: 'Your verification code is 123456', });

// Check delivery status if (result.status === SMSRequestResult.SUCCESS) { console.log('SMS sent successfully!'); console.log('Message ID:', result.messageId); console.log('Recipient:', result.mobile); } else { console.error('SMS delivery failed'); console.error('Error Code:', result.errorCode); console.error('Error Message:', result.errorMessage); }

Batch Messaging (Same Message to Multiple Recipients)

Send the same message to multiple recipients efficiently:

// Batch send with same message const results = await smsService.send({ mobileList: [ '0987654321', '0912345678', '0923456789', '0934567890' ], text: 'Important notification: Your order has been shipped!', });

// Process results console.log(Total sent: ${results.length});

const successful = results.filter(r => r.status === SMSRequestResult.SUCCESS); const failed = results.filter(r => r.status === SMSRequestResult.FAILED);

console.log(Successful: ${successful.length}); console.log(Failed: ${failed.length});

// Log failed deliveries failed.forEach(result => { console.error(Failed to send to ${result.mobile}:, result.errorMessage); });

Multi-Target Messaging (Different Messages)

Send different messages to different recipients:

// Send different messages to each recipient const results = await smsService.send([ { mobile: '0987654321', text: 'Dear John, your appointment is confirmed for tomorrow at 10 AM.', }, { mobile: '0912345678', text: 'Hi Mary, your package will arrive today between 2-4 PM.', }, { mobile: '0923456789', text: 'Hello Mike, thank you for your purchase! Your receipt is attached.', }, ]);

// Check each result results.forEach((result, index) => { console.log(Message ${index + 1} to ${result.mobile}: ${result.status});

if (result.status === SMSRequestResult.SUCCESS) { console.log( Message ID: ${result.messageId}); } else { console.error( Error: ${result.errorMessage}); } });

Taiwan Mobile Number Handling

Automatic Number Normalization

The adapter automatically normalizes Taiwan mobile numbers:

// All these formats are normalized to 0987654321 const validFormats = [ '0987654321', // Standard format '0987-654-321', // With dashes '+886987654321', // International format '886987654321', // International without + '+886-987654321', // International with dash after country code ];

// All will be normalized and send successfully for (const number of validFormats) { const result = await smsService.send({ mobile: number, text: 'Test message', });

// Result.mobile will always be '0987654321' console.log('Normalized number:', result.mobile); }

Number Validation

Validate Taiwan mobile numbers with strict mode:

// Enable Taiwan-only validation const strictService = new SMSServiceEvery8D({ username: process.env.EVERY8D_USERNAME!, password: process.env.EVERY8D_PASSWORD!, onlyTaiwanMobileNumber: true, // Enable strict validation });

try { // This will work - valid Taiwan mobile number await strictService.send({ mobile: '0987654321', // Taiwan number (09xxxxxxxx) text: 'Valid Taiwan number', });

// This will throw error - international number await strictService.send({ mobile: '+1234567890', // Non-Taiwan number text: 'Invalid for Taiwan-only mode', }); } catch (error) { console.error('Number validation error:', error.message); // Error: +1234567890 is not taiwan mobile phone (onlyTaiwanMobileNumber option is true) }

// Taiwan number format requirements: // - Must start with 09 (or +8869, 8869) // - Total 10 digits after country code // - Examples: 0912345678, 0923456789, 0987654321

International Numbers

Send to international numbers when validation is disabled:

// Allow international numbers const globalService = new SMSServiceEvery8D({ username: process.env.EVERY8D_USERNAME!, password: process.env.EVERY8D_PASSWORD!, onlyTaiwanMobileNumber: false, // Default: allow all numbers });

// Send to various countries const results = await globalService.send([ { mobile: '0987654321', text: 'Taiwan message' }, // Taiwan { mobile: '+85298765432', text: 'Hong Kong message' }, // Hong Kong { mobile: '+60123456789', text: 'Malaysia message' }, // Malaysia { mobile: '+6591234567', text: 'Singapore message' }, // Singapore ]);

// Note: Check with Every8D for international coverage and rates

Configuration

Environment Variables

.env

EVERY8D_USERNAME=your_every8d_username EVERY8D_PASSWORD=your_every8d_password EVERY8D_BASE_URL=https://api.e8d.tw EVERY8D_TAIWAN_ONLY=true

TypeScript Configuration

// config.ts export interface SMSConfig { username: string; password: string; baseUrl?: string; onlyTaiwanMobileNumber?: boolean; }

export const smsConfig: SMSConfig = { username: process.env.EVERY8D_USERNAME!, password: process.env.EVERY8D_PASSWORD!, baseUrl: process.env.EVERY8D_BASE_URL || 'https://api.e8d.tw', onlyTaiwanMobileNumber: process.env.EVERY8D_TAIWAN_ONLY === 'true', };

Error Handling

Handling Delivery Failures

import { SMSServiceEvery8D } from '@rytass/sms-adapter-every8d'; import { SMSRequestResult } from '@rytass/sms'; import { Every8DError } from '@rytass/sms-adapter-every8d';

async function sendWithRetry( smsService: SMSServiceEvery8D, mobile: string, text: string, maxRetries: number = 3 ): Promise<boolean> { for (let attempt = 1; attempt <= maxRetries; attempt++) { try { const result = await smsService.send({ mobile, text });

  if (result.status === SMSRequestResult.SUCCESS) {
    console.log(`SMS sent successfully on attempt ${attempt}`);
    return true;
  }

  // Check error code
  if (result.errorCode === Every8DError.FORMAT_ERROR) {
    console.error('Invalid format - no retry needed');
    return false;
  }

  console.warn(`Attempt ${attempt} failed:`, result.errorMessage);

  if (attempt &#x3C; maxRetries) {
    // Wait before retry (exponential backoff)
    await new Promise(resolve =>
      setTimeout(resolve, Math.pow(2, attempt) * 1000)
    );
  }
} catch (error) {
  console.error(`Attempt ${attempt} error:`, error);

  if (attempt === maxRetries) {
    throw error;
  }
}

}

return false; }

Batch Error Handling

async function sendBatchWithErrorHandling( smsService: SMSServiceEvery8D, phoneNumbers: string[], message: string ): Promise<{ successful: string[]; failed: Array<{ phone: string; error: string }>; }> { const results = await smsService.send({ mobileList: phoneNumbers, text: message, });

const successful: string[] = []; const failed: Array<{ phone: string; error: string }> = [];

results.forEach(result => { if (result.status === SMSRequestResult.SUCCESS) { successful.push(result.mobile); } else { failed.push({ phone: result.mobile, error: result.errorMessage || 'Unknown error', }); } });

// Log failures if (failed.length > 0) { console.error('Failed deliveries:', failed); }

return { successful, failed }; }

Best Practices

Message Content

class MessageTemplates { /**

Verification code template
- Keep message under 70 characters for single SMS
- Include expiration time
- Add security warning */ static verification(code: string): string { return 您的驗證碼是 ${code}，10 分鐘內有效。請勿將此驗證碼告知他人。; }

/**

Order confirmation template
- Include order number for reference
- Keep essential info only */ static orderConfirmation(orderNumber: string, amount: number): string { return 訂單 ${orderNumber} 已確認。金額：NT$${amount}。感謝您的購買！; }

/**

Appointment reminder template
- Include date, time, and location
- Add action instructions */ static appointmentReminder(date: string, time: string): string { return 預約提醒：${date} ${time}。請提前 10 分鐘報到。如需取消請來電。; }

/**

Marketing campaign template
- Include opt-out instructions for compliance
- Keep under 70 characters if possible */ static promotion(discount: string): string { return 限時優惠！${discount} 折扣活動進行中。查看詳情：[連結]。回 N 取消訂閱。; } }

Security

// 1. Store credentials securely // ❌ Don't hardcode credentials const badService = new SMSServiceEvery8D({ username: 'myusername', password: 'mypassword', });

// ✅ Use environment variables const goodService = new SMSServiceEvery8D({ username: process.env.EVERY8D_USERNAME!, password: process.env.EVERY8D_PASSWORD!, });

// 2. Validate phone numbers before sending function isValidTaiwanMobile(phone: string): boolean { const cleaned = phone.replace(/[^0-9]/g, '').replace(/^886/, '0'); return /^09\d{8}$/.test(cleaned); }

// 3. Implement rate limiting class RateLimitedSMSService { private lastSendTime = 0; private minInterval = 1000; // 1 second between sends

async send(smsService: SMSServiceEvery8D, data: any) { const now = Date.now(); const timeSinceLastSend = now - this.lastSendTime;

if (timeSinceLastSend &#x3C; this.minInterval) {
  await new Promise(resolve =>
    setTimeout(resolve, this.minInterval - timeSinceLastSend)
  );
}

const result = await smsService.send(data);
this.lastSendTime = Date.now();

return result;

} }

// 4. Log all SMS activities for audit async function sendWithAuditLog( smsService: SMSServiceEvery8D, mobile: string, text: string, userId?: string ): Promise<void> { const auditEntry = { timestamp: new Date(), userId, recipient: mobile, messageLength: text.length, action: 'SMS_SEND', };

try { const result = await smsService.send({ mobile, text });

await logAudit({
  ...auditEntry,
  status: result.status,
  messageId: result.messageId,
});

} catch (error) { await logAudit({ ...auditEntry, status: 'ERROR', error: error.message, }); throw error; } }

async function logAudit(entry: any): Promise<void> { // Save to database or logging service }

Performance

// 1. Batch messages efficiently // ❌ Don't send one by one async function inefficientSend(phones: string[], message: string) { for (const phone of phones) { await smsService.send({ mobile: phone, text: message }); } }

// ✅ Use batch send async function efficientSend(phones: string[], message: string) { await smsService.send({ mobileList: phones, text: message }); }

// 2. Handle large batches with chunking async function sendLargeBatch( smsService: SMSServiceEvery8D, phones: string[], message: string, chunkSize: number = 100 ): Promise<void> { for (let i = 0; i < phones.length; i += chunkSize) { const chunk = phones.slice(i, i + chunkSize);

await smsService.send({
  mobileList: chunk,
  text: message,
});

// Add delay between chunks
if (i + chunkSize &#x3C; phones.length) {
  await new Promise(resolve => setTimeout(resolve, 1000));
}

} }

Compliance

// 1. Respect user preferences and opt-out requests interface UserSMSPreference { phoneNumber: string; optedOut: boolean; marketingConsent: boolean; transactionalOnly: boolean; }

async function sendRespectingPreferences( smsService: SMSServiceEvery8D, user: UserSMSPreference, message: string, messageType: 'marketing' | 'transactional' ): Promise<boolean> { // Check if user opted out completely if (user.optedOut) { console.log('User opted out - skipping SMS'); return false; }

// Check marketing consent if (messageType === 'marketing' && !user.marketingConsent) { console.log('No marketing consent - skipping SMS'); return false; }

// Send the message const result = await smsService.send({ mobile: user.phoneNumber, text: message, });

return result.status === SMSRequestResult.SUCCESS; }

// 2. Include opt-out instructions in marketing messages function createMarketingMessage(content: string): string { return ${content}\n\n回覆 N 取消訂閱簡訊通知。; }

// 3. Maintain do-not-contact list class DoNotContactList { private blockedNumbers = new Set<string>();

async add(phoneNumber: string): Promise<void> { this.blockedNumbers.add(phoneNumber); // Persist to database }

async remove(phoneNumber: string): Promise<void> { this.blockedNumbers.delete(phoneNumber); // Update database }

isBlocked(phoneNumber: string): boolean { return this.blockedNumbers.has(phoneNumber); }

async filterAllowed(phoneNumbers: string[]): Promise<string[]> { return phoneNumbers.filter(phone => !this.isBlocked(phone)); } }

Internal Implementation Details

Empty Target Handling

傳入空陣列或空 mobileList 會拋出錯誤：

// 以下情況會拋出 'No target provided.' 錯誤 await smsService.send([]); // 空陣列 await smsService.send({ mobileList: [], text: 'Test' }); // 空 mobileList

Batch Message Optimization

相同訊息內容的多個請求會自動合併為單一 API 呼叫，提高發送效率：

// 這三個請求會合併成一個 API 呼叫 const results = await smsService.send([ { mobile: '0912345678', text: 'Hello' }, { mobile: '0923456789', text: 'Hello' }, // 相同訊息 { mobile: '0934567890', text: 'Hello' }, // 相同訊息 ]); // 內部會將 DEST 參數合併為 '0912345678,0923456789,0934567890'

Partial Delivery Failure Handling

當部分發送失敗時，API 回傳 unsend 數量，系統會從列表末端開始標記失敗：

// 假設發送 5 個號碼，API 回傳 unsend=2 // 則前 3 個標記為 SUCCESS，後 2 個標記為 FAILED const results = await smsService.send({ mobileList: ['0911...', '0922...', '0933...', '0944...', '0955...'], text: 'Test', }); // results[0..2].status === SMSRequestResult.SUCCESS // results[3..4].status === SMSRequestResult.FAILED

Troubleshooting

Common Issues

Authentication Failure

Symptoms:

All messages fail to send
Error message about credentials

Solutions:

// Check credentials console.log('Username:', process.env.EVERY8D_USERNAME); console.log('Password length:', process.env.EVERY8D_PASSWORD?.length);

// Ensure no extra spaces in .env EVERY8D_USERNAME=your_username # ❌ Trailing space EVERY8D_USERNAME=your_username # ✅ No space

// Test with minimal code const testService = new SMSServiceEvery8D({ username: 'YOUR_USERNAME', password: 'YOUR_PASSWORD', });

const result = await testService.send({ mobile: '0987654321', text: 'Test', });

console.log('Result:', result);

Invalid Phone Number Format

Symptoms:

FORMAT_ERROR (-306) error code
Message fails for specific numbers

Solutions:

// Enable Taiwan-only validation const service = new SMSServiceEvery8D({ username: process.env.EVERY8D_USERNAME!, password: process.env.EVERY8D_PASSWORD!, onlyTaiwanMobileNumber: true, });

// Validate before sending function validateTaiwanMobile(phone: string): boolean { const normalized = phone.replace(/[^0-9]/g, '').replace(/^886/, '0'); return /^09\d{8}$/.test(normalized); }

if (!validateTaiwanMobile(phoneNumber)) { console.error('Invalid Taiwan mobile number:', phoneNumber); }

Message Not Delivered

Symptoms:

Status shows SUCCESS but message not received
Delays in delivery

Solutions:

// 1. Check message content // - Avoid special characters that might cause issues // - Keep message under 70 characters for single SMS

// 2. Verify phone number is active // - Test with your own phone first

// 3. Check account balance // - Contact Every8D to verify account status

// 4. Log message ID for tracking const result = await smsService.send({ mobile, text }); console.log('Message ID for tracking:', result.messageId);
