Installation

npm install node-maw

Usage

Unified Client (Recommended)

import { NodeMaw } from "node-maw";

const client = new NodeMaw();

// Fetch App Store version
const appStoreVersion = await client.getAppStoreVersion("com.example.app");
console.log(appStoreVersion);

// Fetch Play Store version
const playStoreVersion = await client.getPlayStoreVersion("com.example.app");
console.log(playStoreVersion);

// Access individual clients for advanced features
const appExists = await client.appStore.exists("com.example.app");
const appDetails = await client.playStore.getFullDetails("com.example.app");

// Check for updates (NEW!)
const appStoreUpdate = await client.checkAppStoreForUpdates(
  "com.example.app",
  "1.0.0"
);
const playStoreUpdate = await client.checkPlayStoreForUpdates(
  "com.example.app",
  "1.0.0"
);

if (appStoreUpdate.updateAvailable) {
  console.log(`📱 App Store update available: ${appStoreUpdate.latestVersion}`);
}

Separate Clients

import { AppStoreClient, PlayStoreClient } from "node-maw";

// App Store client with specific configuration
const appStoreClient = new AppStoreClient({
  country: "ca",
  includeMetadata: true,
});

// Play Store client with specific configuration
const playStoreClient = new PlayStoreClient({
  language: "es",
  country: "mx",
});

const appStoreVersion = await appStoreClient.getVersion("com.example.app");
const playStoreVersion = await playStoreClient.getVersion("com.example.app");

Default Instances

import nodeMaw, { appStore, playStore } from "node-maw";

// Using default unified client
const version1 = await nodeMaw.getAppStoreVersion("com.example.app");

// Using default App Store client
const version2 = await appStore.getVersion("com.example.app");

// Using default Play Store client
const version3 = await playStore.getVersion("com.example.app");

Advanced Usage

Update Checking (NEW!)

Check if an app has updates available by comparing the current version with the latest version from the store:

import { NodeMaw } from "node-maw";

const client = new NodeMaw();

// Check App Store for updates
const appStoreUpdate = await client.checkAppStoreForUpdates(
  "net.whatsapp.WhatsApp",
  "2.20.0"
);

console.log(`Update available: ${appStoreUpdate.updateAvailable}`);
console.log(`Current version: ${appStoreUpdate.currentVersion}`);
console.log(`Latest version: ${appStoreUpdate.latestVersion}`);

if (appStoreUpdate.updateAvailable) {
  console.log("Update details:", appStoreUpdate.updateDetails);
}

// Check Play Store for updates
const playStoreUpdate = await client.checkPlayStoreForUpdates(
  "com.whatsapp",
  "2.20.0"
);

// Use direct client access for more control
const directCheck = await client.appStore.checkForUpdates(
  "com.example.app",
  "1.0.0"
);

The UpdateCheckResult interface provides:

• updateAvailable: Boolean indicating if update is available
• currentVersion: The version you're checking against
• latestVersion: The latest version available in the store
• versionComparison: Numeric comparison result (negative = older, 0 = same, positive = newer)
• updateDetails: Full app details if an update is available (undefined otherwise)

Different Store Regions

// App Store in different countries
const canadaClient = new AppStoreClient({ country: "ca" });
const ukClient = new AppStoreClient({ country: "gb" });

// Play Store in different languages/countries
const spanishClient = new PlayStoreClient({
  language: "es",
  country: "mx",
});

Search Functionality

// Search App Store
const appStoreResults = await client.appStore.search("calculator", 10);

// Search Play Store with options
const playStoreResults = await client.playStore.search("calculator", {
  num: 10,
  fullDetail: true,
});

Configuration Management

const client = new NodeMaw({
  timeout: 15000,
  appStore: {
    country: "ca",
    includeMetadata: true,
  },
  playStore: {
    language: "fr",
    country: "ca",
    retryAttempts: 5,
  },
});

// Update configuration later
client.updateConfig({
  timeout: 20000,
  appStore: { country: "us" },
});

Types

interface AppVersion {
  version: string; // App version (e.g., "1.0.0")
  releaseDate: string; // ISO date string
  releaseNotes?: string; // Optional release notes
  bundleId?: string; // iOS bundle ID (App Store only)
  packageName?: string; // Android package name (Play Store only)
}

interface UpdateCheckResult {
  updateAvailable: boolean; // Whether an update is available
  currentVersion: string; // The version being checked
  latestVersion: string; // Latest version available in store
  versionComparison: number; // -1: older, 0: same, 1: newer
  updateDetails?: AppVersion; // Full app details if update available
}
