## 💡 What It Does

`npm-caffeine` is a simple CLI tool that helps prevent your dev environment, tunnel, or server from going idle or sleeping by sending periodic HTTP requests to a specified URL. It also logs uptime, so you can see how long your session has been running.

## 📦 Installation

### Globally (recommended)

```bash
npm install -g npm-caffeine
```

### Or use without installing

```bash
npx npm-caffeine <url> [interval]
```

### 🚀 Usage

```bash
caffeine <url> [interval]
```

- [url]: The URL you want to ping (e.g., http://localhost:3000, https://example.com).

- [interval]: (Optional) How often to ping the URL in seconds. Default is 60.

### ✅ Examples

```bash
# Ping localhost every 30 seconds

caffeine http://localhost:3000 30
```

```bash
# Ping a remote URL every 1 minute
caffeine https://example.com

```
