## About The Project

**Thunder** is a powerful Telegram bot that transforms Telegram files into high-speed direct links, perfect for both streaming and rapid downloading. Share files via HTTP(S) links without needing to download them from the Telegram client first.

### 💡 Perfect For

- 🚀 Bypassing Telegram's built-in download speed limits
- ☁️ Unlimited cloud storage with fast streaming and download links
- 🎬 Content creators sharing media files
- 👥 Communities distributing resources
- 🎓 Educational platforms sharing materials

## How It Works

```
User Uploads File → Telegram Bot → Forwards to Channel → Generates Direct Link → Direct Download / Streaming
```

1. **Upload** → User sends any file to the bot.
2. **Store** → The bot forwards the file to your private storage channel (`BIN_CHANNEL`), where it is permanently saved to generate the link.
3. **Generate** → A unique, permanent link is created.
4. **Stream/Download** → Anyone with the link can stream or download the file directly in their browser.
5. **Balance** → Multi-client support distributes the load for high availability.

## Features

#### Core Functionality

## Reverse Proxy Setup

<details>
<summary>Reverse Proxy Guide</summary>

This guide will help you set up a secure reverse proxy using **NGINX** for your file streaming bot with **Cloudflare SSL protection**.

---

#### ✅ What You Need

- A **VPS or server** running Ubuntu/Debian with NGINX installed.
- Your **file streaming bot** running on a local port (e.g., `8080`).
- A **subdomain** (e.g., `f2l.thunder.com`) set up in **Cloudflare**.
- **Cloudflare Origin Certificate** files: `cert.pem` and `key.key`.

---

#### 🔐 Step 1: Configure Cloudflare

- **DNS**: Add an `A` record for your subdomain pointing to your server's IP. Ensure **Proxy Status** is **Proxied (orange cloud)**.
- **SSL**: In the **SSL/TLS** tab, set the encryption mode to **Full (strict)**.

---

#### 🛡️ Step 2: Set Up SSL Certificates on Server

Create a folder for your certificates and place `cert.pem` and `key.key` inside. Secure the private key.

```bash
sudo mkdir -p /etc/ssl/cloudflare/f2l.thunder.com
# Move/copy your cert.pem and key.key files into this directory
sudo chmod 600 /etc/ssl/cloudflare/f2l.thunder.com/key.key
sudo chmod 644 /etc/ssl/cloudflare/f2l.thunder.com/cert.pem
```

---

#### 🛠️ Step 3: Create NGINX Configuration

Create a new file at `/etc/nginx/sites-available/f2l.thunder.conf` and paste the following, replacing `f2l.thunder.com` and `8080` with your values.

```nginx
server {
    listen 443 ssl;
    listen [::]:443 ssl;
    server_name f2l.thunder.com;

# SSL Configuration
    ssl_certificate     /etc/ssl/cloudflare/f2l.thunder.com/cert.pem;
    ssl_certificate_key /etc/ssl/cloudflare/f2l.thunder.com/key.key;

# Basic security
    add_header X-Frame-Options DENY;
    add_header X-Content-Type-Options nosniff;

location / {
        # Forward requests to your bot
        proxy_pass http://localhost:8080;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        
        # Settings for file streaming
        proxy_buffering off;
        proxy_request_buffering off;
        client_max_body_size 0;
    }
}

# Redirect HTTP to HTTPS
server {
    listen 80;
    listen [::]:80;
    server_name f2l.thunder.com;
    return 301 https://$host$request_uri;
}
```

---

#### 🔄 Step 4: Test and Apply Changes

Enable the configuration, test it, and reload NGINX.

```bash
sudo ln -s /etc/nginx/sites-available/f2l.thunder.conf /etc/nginx/sites-enabled/
sudo nginx -t
sudo systemctl reload nginx
```

Your reverse proxy is now securely streaming files behind Cloudflare!

### Troubleshooting & FAQ

#### **Initial Setup**

**Q: Why isn't my bot responding after setup?**
A: This is usually a configuration issue. Please check the following:

1. **Verify `config.env`**: Make sure all essential variables (`API_ID`, `API_HASH`, `BOT_TOKEN`, `BIN_CHANNEL`, `DATABASE_URL`) are filled in correctly.
2. **Use `config.env` Only**: Do not edit `vars.py` or `config_sample.env`. The bot is designed to only read your settings from `config.env`.
3. **Check Logs**: Review the console logs on your server or hosting platform (Koyeb, Render, Heroku) for any startup errors.

**Q: What do I use for the `FQDN` variable?**
A: It's the public URL or IP address of your bot.

- **With a Domain**: Use your subdomain (e.g., `f2l.thunder.com`).
- **On Koyeb/Render/Heroku**: Use the public URL provided by the platform.
- **On a VPS**: Use your server's public IP address.

**Q: Why are my links not working on a VPS?**
A: For links to work on a VPS, the URL must include the port number (e.g., `http://YOUR_VPS_IP:8080`). Ensure that `NO_PORT` is set to `False` in `config.env` and that your server is configured to allow traffic through that port.

#### **Common Errors**

**Q: Why are my links showing a "Resource Not Found" error or not working?**
A: This error means the bot can't access the file. Check these three things:

1. **Invalid Token**: Your `BOT_TOKEN` or one of the `MULTI_TOKEN`s might be wrong. Double-check them with @BotFather.
2. **Missing Admin Rights**: The bot and **all** your client accounts must be **administrators** in the `BIN_CHANNEL`.
3. **File Deleted**: The link will break if the file was deleted from your `BIN_CHANNEL`.

**Q: Why isn't video or audio playing correctly in my browser?**
A: Your browser likely doesn't support the file's audio or video format (codec). This is a browser limitation, not a bot issue.

- **Solution**: For perfect playback, copy the link and play it in a dedicated media player. Recommended players include **VLC Media Player**, **MX Player**, **PotPlayer**, **IINA**, and **MPV**.

**Q: Why does the bot sometimes become unresponsive?**
A: This is likely a **Telegram Flood Wait**. To prevent spam, Telegram temporarily limits accounts that make too many requests. The bot is designed to handle this automatically by pausing and will resume on its own once the limit is lifted.

#### **Performance**

**Q: How can I fix slow download and streaming speeds?**
A: If your speeds are slow, here’s how to fix it:

- **Add More Clients**: This is the best solution. Add `MULTI_TOKEN`s to your `config.env` to distribute the workload and increase throughput.
- **Use DC4 Accounts**: For top performance, use Telegram accounts from **Data Center 4 (DC4)**, as they often have the fastest connection. Use `/dc` to check an account's data center.
- **Upgrade Your Server**: A server with a slow network will bottleneck your speeds. Consider upgrading your VPS plan.

#### **Bot Usage**

**Q: How do I generate links for multiple files at once?**
A: The `/link` command can process multiple files sent in sequence. To use it, **reply to the first file** of the series with the command and the total count.

- **Example**: For a series of 5 files, reply to the very first file with `/link 5`.

**Q: Can I mix tokens from different accounts and data centers?**
A: Yes. Mixing clients from different accounts and data centers (like DC1, DC4, and DC5) is a great way to improve bot performance and reliability.
