## ⚙️ Installation

> Requires **Node.js v20+**

```bash
npm i ws3-fca@latest
```

---

## 🚀 Getting Started

### 1. Generate `appstate.json`

This file contains your Facebook session cookies.
Use a browser extension (e.g. "C3C FbState", "CookieEditor") to export cookies after logging in, and save them in this format:

```json
[
  {
    "key": "c_user",
    "value": "your-id"
  }
]
```

If you don't know how to get cookie, you can follow this tutorial **[here](https://appstate-tutorial-ws3.pages.dev)**.

Place this file in the root directory as `appstate.json`.

---

### 2. Basic Usage Example

```js
const fs = require("fs");
const path = require("path");
const { login } = require("ws3-fca");

let credentials;
try {
  credentials = { appState: JSON.parse(fs.readFileSync("appstate.json", "utf8")) };
} catch (err) {
  console.error("❌ appstate.json is missing or malformed.", err);
  process.exit(1);
}

console.log("Logging in...");

login(credentials, {
  online: true,
  updatePresence: true,
  selfListen: false,
  randomUserAgent: false
}, async (err, api) => {
  if (err) return console.error("LOGIN ERROR:", err);

  console.log(`✅ Logged in as: ${api.getCurrentUserID()}`);

  const commandsDir = path.join(__dirname, "modules", "commands");
  const commands = new Map();

  if (!fs.existsSync(commandsDir)) fs.mkdirSync(commandsDir, { recursive: true });

  for (const file of fs.readdirSync(commandsDir).filter(f => f.endsWith(".js"))) {
    const command = require(path.join(commandsDir, file));
    if (command.name && typeof command.execute === "function") {
      commands.set(command.name, command);
      console.log(`🔧 Loaded command: ${command.name}`);
    }
  }

  api.listenMqtt(async (err, event) => {
    if (err || !event.body || event.type !== "message") return;

    const prefix = "/";
    if (!event.body.startsWith(prefix)) return;

    const args = event.body.slice(prefix.length).trim().split(/ +/);
    const commandName = args.shift().toLowerCase();

    const command = commands.get(commandName);
    if (!command) return;

    try {
      await command.execute({ api, event, args });
    } catch (error) {
      console.error(`Error executing ${commandName}:`, error);
      api.sendMessageMqtt("❌ An error occurred while executing the command.", event.threadID, event.messageID);
    }
  });
});
```
