# Squache

> Cache HTTPS traffic for web scraping. Cut bandwidth costs by 90%.

## Why Squache?

If you're running Puppeteer, Playwright, or any web scraper, you're downloading
the same JavaScript bundles, fonts, and images over and over again. Squache
intercepts HTTPS traffic and caches everything
aggressively reducing bandwidth by 90%+ for repeated crawls.

**Use cases:**
- Running hundreds of Puppeteer instances
- Scraping the same domains repeatedly
- Minimizing expensive residential proxy usage
- Building reproducible scrapers (same cached assets)

## Quick Start

```bash
git clone https://github.com/devrupt-io/squache.git
cd squache
cp example.env .env
docker compose up -d
```

That's it. SSL certificates are generated automatically.

- **Dashboard:** http://localhost:3011
- **Proxy:** http://localhost:3128

**First-time login:** Check the logs for your auto-generated admin password:

```bash
docker compose logs backend | grep -A5 "SQUACHE ADMIN"
```

Or set your own password in `.env`:

```bash
ADMIN_PASS=your-password
```

### Install the CA Certificate

Squache uses SSL bumping to cache HTTPS traffic. Download and install the CA certificate:

```bash
# Download the CA certificate
curl -o squache-ca.crt http://localhost:3010/api/config/ssl/certificate

# Linux
sudo cp squache-ca.crt /usr/local/share/ca-certificates/
sudo update-ca-certificates

# macOS
sudo security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain squache-ca.crt

# Node.js (or add to your shell profile)
export NODE_EXTRA_CA_CERTS=$(pwd)/squache-ca.crt
```

### Use with Puppeteer

```typescript
import puppeteer from 'puppeteer';

const browser = await puppeteer.launch({
  args: ['--proxy-server=http://localhost:3128'],
});

await browser.newPage().then(page => page.goto('https://example.com'));
```

### Use with any HTTP client

```bash
# curl (after installing CA cert)
curl -x http://localhost:3128 https://example.com

# wget
https_proxy=http://localhost:3128 wget https://example.com

# Node.js / Python
export HTTPS_PROXY=http://localhost:3128
```

## How It Works

    subgraph Scraper["Your Scraper"]
        A1["Puppeteer"]
        A2["curl"]
        A3["Python"]
    end

subgraph Squache
        Proxy["Squid Proxy<br/>(SSL Bump + Cache)"]
        Dashboard["Dashboard<br/>(Next.js)"]
        API["API<br/>(Express.js)"]
        DB[(PostgreSQL)]
        
        Dashboard --> API --> DB
        API -.-> Proxy
    end

Scraper --> Proxy --> Internet((Internet))
```

**Key features:**
- **SSL Bumping** - Decrypts HTTPS to cache responses (generates certs on-the-fly)
- **Aggressive Caching** - Forces caching of JS, CSS, images, fonts, and media
- **Web Dashboard** - Real-time bandwidth metrics and cache hit rates
- **Zero Config** - SSL certificates auto-generated on first run

## Dashboard

The dashboard shows real-time statistics:
- Bandwidth saved vs. bandwidth used
- Cache hit/miss ratios
- Per-domain statistics
- Request logs with search

Access at http://localhost:3011 after starting the services.

## Configuration

### Environment Variables

All configuration is done through `.env`. Copy the example file and customize:

```bash
cp example.env .env
```

Key settings you may want to change:

```bash
# Admin credentials (password auto-generated if empty)
ADMIN_EMAIL=admin@example.com
ADMIN_PASS=your-secure-password  # Leave empty to auto-generate on each start

# Security (generate with: openssl rand -hex 32)
JWT_SECRET=your-random-secret

# If exposing to the internet (update all three to your domain)
BACKEND_URL=https://api.squache.yourdomain.com
FRONTEND_URL=https://squache.yourdomain.com
CORS_ORIGIN=https://squache.yourdomain.com
NEXT_PUBLIC_API_URL=https://api.squache.yourdomain.com
NEXT_PUBLIC_SITE_URL=https://squache.yourdomain.com
```

## API Reference

### Stats
| Method | Endpoint | Description |
|--------|----------|-------------|
| GET | `/api/stats` | Overall statistics |
| GET | `/api/stats/bandwidth?range=1h` | Bandwidth over time |
| GET | `/api/stats/domains` | Per-domain breakdown |

### Cache
| Method | Endpoint | Description |
|--------|----------|-------------|
| GET | `/api/cache` | Cache size and object count |
| DELETE | `/api/cache` | Purge all cache (admin) |

### Logs
| Method | Endpoint | Description |

| GET | `/api/logs/search?url=...` | Search logs |

### SSL (Public)
| Method | Endpoint | Description |
|--------|----------|-------------|
| GET | `/api/config/ssl/certificate` | Download CA cert (no auth) |

### Upstream Proxies (v0.2.0)

## Bandwidth Savings

Typical savings for web scraping workloads:

|-------------|----------------|
| JavaScript/CSS | 95%+ |
| Images/Fonts | 90%+ |
| Video/Media | 85%+ |
| Repeated crawls | 90%+ overall |

## Development

```bash
# Clone
git clone https://github.com/devrupt-io/squache.git
cd squache

# Start in development mode
docker compose up -d

# Watch logs
docker compose logs -f

# Rebuild after changes
docker compose up -d --build
```

## Roadmap

### v1.0.0 - Upstream Proxy Routing

Route requests through VPN or residential proxies based on HTTP headers:

```typescript
await page.setExtraHTTPHeaders({
  'X-Squache-Upstream': 'residential',  // vpn | residential | direct
  'X-Squache-Country': 'US',            // ISO country code
});
```

- [ ] Wire up Squid ACLs for header-based routing
- [ ] Provider integrations (Webshare, Bright Data, Oxylabs)
- [ ] Load balancing across multiple upstream proxies
- [ ] Automatic failover

> **Note:** The infrastructure exists (database models, API endpoints, config
> generation in
> [backend/src/routes/upstreams.ts](backend/src/routes/upstreams.ts)), but Squid
> routing rules are not yet fully wired up.
