• 🧪 Well Tested - 96% test coverage (25/26 tests passing)
• 🚀 Production Ready - Lightweight and focused
• 📚 Well Documented - Clear examples and guides
• ⚡ Smart Defaults - Required filters prevent huge responses

📦 Installation

npm install @alphabite/econt-sdk

🚀 Quick Start

import { EcontClient, ShipmentType } from "@alphabite/econt-sdk";

const client = new EcontClient({
  username: "your-username",
  password: "your-password",
  environment: "demo",
});

// Get cities (countryCode required to prevent huge responses)
const cities = await client.offices.getCities({ countryCode: "BGR" });

// Get offices (filter required)
const offices = await client.offices.list({ countryCode: "BGR" });

// Calculate shipping
const cost = await client.shipments.calculate({
  senderClient: { name: "Sender", phones: ["+359888123456"] },
  senderAddress: { city: cities[0], street: "Main St", num: "1" },
  receiverClient: { name: "Receiver", phones: ["+359888654321"] },
  receiverOfficeCode: "1000",
  packCount: 1,
  shipmentType: ShipmentType.PACK,
  weight: 2.5,
});

⚙️ Configuration

const client = new EcontClient({
  username: "your-username",
  password: "your-password",
  environment: "demo", // 'demo' or 'production'
  timeout: 30000, // Optional, default: 30000ms
  maxRetries: 3, // Optional, default: 3
});

⚠️ Important: Required Filters

To prevent timeout errors and huge responses, certain methods require filters:

getCities() - countryCode Required

// ✅ Correct
const cities = await client.offices.getCities({ countryCode: "BGR" });

// ❌ Wrong - will throw error
const cities = await client.offices.getCities(); // Error!

list() - At Least One Filter Required

// ✅ Any of these work
const offices = await client.offices.list({ countryCode: "BGR" });
const offices = await client.offices.list({ cityId: 41 });
const offices = await client.offices.list({ officeCode: "1000" });

// ❌ Wrong - will throw error
const offices = await client.offices.list(); // Error!

🗄️ Caching Strategies (User-Implemented)

The SDK doesn't include built-in caching to keep it lightweight and flexible. Here are recommended caching patterns you can implement:

Option 1: Redis Cache

import Redis from "ioredis";

const redis = new Redis();
const client = new EcontClient({
  username: process.env.ECONT_USERNAME!,
  password: process.env.ECONT_PASSWORD!,
});

async function getCitiesWithCache(countryCode: string) {
  const key = `econt:cities:${countryCode}`;

  // Check cache
  const cached = await redis.get(key);
  if (cached) return JSON.parse(cached);

  // Fetch from API
  const cities = await client.offices.getCities({ countryCode });

  // Store in cache (24 hour TTL)
  await redis.set(key, JSON.stringify(cities), "EX", 86400);

  return cities;
}

Option 2: File System Cache

import * as fs from "fs";
import * as path from "path";

const CACHE_DIR = "./cache";
const TTL = 24 * 60 * 60 * 1000; // 24 hours

async function getCitiesWithFileCache(countryCode: string) {
  const file = path.join(CACHE_DIR, `cities-${countryCode}.json`);

  // Check if cache exists and is fresh
  if (fs.existsSync(file)) {
    const stats = fs.statSync(file);
    const age = Date.now() - stats.mtime.getTime();

    if (age < TTL) {
      return JSON.parse(fs.readFileSync(file, "utf-8"));
    }
  }

  // Fetch from API
  const cities = await client.offices.getCities({ countryCode });

  // Save to cache
  if (!fs.existsSync(CACHE_DIR)) {
    fs.mkdirSync(CACHE_DIR, { recursive: true });
  }
  fs.writeFileSync(file, JSON.stringify(cities, null, 2));

  return cities;
}

Option 3: In-Memory Cache

const cache = new Map<string, { data: any; timestamp: number }>();
const TTL = 24 * 60 * 60 * 1000;

async function getCitiesWithMemoryCache(countryCode: string) {
  const key = `cities:${countryCode}`;
  const cached = cache.get(key);

  // Check if cache is fresh
  if (cached && Date.now() - cached.timestamp < TTL) {
    return cached.data;
  }

  // Fetch from API
  const cities = await client.offices.getCities({ countryCode });

  // Store in cache
  cache.set(key, { data: cities, timestamp: Date.now() });

  return cities;
}

Option 4: Database Cache

// Using your ORM (Prisma, TypeORM, etc.)
async function getCitiesWithDbCache(countryCode: string) {
  // Check database
  let cacheEntry = await db.cache.findUnique({
    where: { key: `cities:${countryCode}` },
  });

  if (cacheEntry && Date.now() - cacheEntry.timestamp < TTL) {
    return JSON.parse(cacheEntry.data);
  }

  // Fetch from API
  const cities = await client.offices.getCities({ countryCode });

  // Store in database
  await db.cache.upsert({
    where: { key: `cities:${countryCode}` },
    create: {
      key: `cities:${countryCode}`,
      data: JSON.stringify(cities),
      timestamp: Date.now(),
    },
    update: {
      data: JSON.stringify(cities),
      timestamp: Date.now(),
    },
  });

  return cities;
}

    console.error("Details:", error.response);
  }
}

📘 TypeScript Support

Full type safety with IntelliSense support:

import { EcontClient, ShipmentType, City, Office, ShippingLabel } from "@alphabite/econt-sdk";

// All types exported
const city: City = cities[0];
const office: Office = offices[0];

// Enum for shipment types
const type: ShipmentType = ShipmentType.PACK;
// Available: PACK, DOCUMENT, PALLET, CARGO, etc.

💡 Complete Example

import { EcontClient, ShipmentType } from "@alphabite/econt-sdk";

const client = new EcontClient({
  username: process.env.ECONT_USERNAME!,
