✨ About This Project

linejs-android serves as a Line Messaging API SDK built with JavaScript/Node.js, optimized to run stably on Android-based systems (including Termux and Android WebView implementations).
Additionally, it has been adapted to support Primary Token Login, allowing developers to authenticate directly with a primary token without the need for QR or password-based login.

The main goals of this project are to:

• 🔧 Provide a lightweight and faster SDK for Android environments.
• 🔒 Support authentication using Primary Tokens.
• ⚡ Simplify LINE API integration in Android-based Node.js applications.
• 📱 Enable automation, bots, and custom integrations with the LINE platform on mobile devices.

🧠 Usage Example

git clone https://github.com/fckveza/linejs-android.git
cd linejs-android
node app.js

Import the modules as usual:

import { BaseClient } from "./koncet/linejs/base/mod.js";
import { FileStorage } from "./koncet/linejs/base/storage/mod.js";

Example login using Primary Token:

import { loginWithAuthToken } from "./mod.js";
import { FileStorage } from "./koncet/linejs/base/storage/mod.js";

const token = "u9f66afc5d1cafcca835f32552abae138:xxxxx";
const storage = new FileStorage("./storage");

const client = await loginWithAuthToken(token, { storage });
console.log("Successfully logged in as:", client.profile.displayName);
