## 📖 Usage
### CLI Commands
| Command | Description | Example |
| --------------------------------- | ----------------------------------- | ------------------------------ |
| `deno task init` | Initialize a new NanoEdgeRT project | `deno task init` |
| `deno task cli add [path]` | Add a new service | `deno task cli add my-api` |
| `deno task cli remove ` | Remove a service | `deno task cli remove my-api` |

| `deno task cli enable ` | Enable a service | `deno task cli enable my-api` |
| `deno task cli disable ` | Disable a service | `deno task cli disable my-api` |
### Creating a Service
1. **Add a new service:**
```bash
deno task cli add my-calculator
```
2. **Edit the service file at `nanoedge/services/my-calculator/index.ts`:**
```typescript
export default async function handler(req: Request): Promise {
const url = new URL(req.url);
const a = parseFloat(url.searchParams.get("a") || "0");
const b = parseFloat(url.searchParams.get("b") || "0");
return new Response(
JSON.stringify({
result: a + b,
timestamp: new Date().toISOString(),
}),
{
status: 200,
headers: { "Content-Type": "application/json" },
},
);
}
```
3. **Test your service:**
```bash
curl "http://0.0.0.0:8000/my-calculator?a=10&b=5"
```
### Service Configuration
Services are configured in `nanoedge/config.json`:
```json
{
"available_port_start": 8001,
"available_port_end": 8999,
"main_port": 8000,
"jwt_secret": "your-secret-key",
"services": [
{
"name": "my-calculator",
"enable": true,
"jwt_check": false,
"permissions": {
"read": ["./data"],
"write": ["./tmp"],
"env": ["DATABASE_URL"],
"run": []
}
}
]
}
```
#### Configuration Options
| Option | Type | Description |
| --------------- | ------- | ------------------------------------------- |
| `name` | string | Unique service name |
| `path` | string | Custom path to service directory (optional) |
| `enable` | boolean | Whether the service is enabled |
| `jwt_check` | boolean | Whether JWT authentication is required |
| `build_command` | string | Command to build the service (optional) |
| `permissions` | object | Deno permissions for the service worker |
## 🔐 Authentication
NanoEdgeRT supports JWT-based authentication for protecting sensitive services.
### Enabling JWT Authentication
1. **Set a secure JWT secret in your config:**
```json
{
"jwt_secret": "your-super-secure-secret-key"
}
```
2. **Enable JWT check for a service:**
```json
{
"name": "protected-service",
"jwt_check": true,
"enable": true
}
```
3. **Make authenticated requests:**
```bash
curl -H "Authorization: Bearer YOUR_JWT_TOKEN" \
http://0.0.0.0:8000/protected-service
```
### JWT Token Format
The JWT token should include the following claims:
```json
{
"sub": "user-id",
"exp": 1640995200,
"iat": 1640908800,
"iss": "nanoedgert"
}
```

### 🔐 Access Control
For enhanced security, NanoEdgeRT implements **IP-based access controls**:
| **Endpoint Type** | **Access** | **Interface** | **Examples** |
| ---------------------- | ----------- | -------------- | ---------------------------------- |
| 🔧 **Admin/Docs** | `127.0.0.1` | Localhost only | `/docs`, `/swagger`, `/_admin/*` |
| 🌐 **Public Services** | `0.0.0.0` | All interfaces | `/hello`, `/calculator`, `/health` |
**Why this design?**
- 🛡️ **Security**: Admin functions only accessible from the server itself
- 🌍 **Accessibility**: Services available to all clients (local and remote)
- ⚡ **Performance**: No overhead for public service calls
- 🔒 **Best Practice**: Follows enterprise security patterns
### System Endpoints

### Optimization Tips
1. **Service Isolation**: Each service runs in its own Deno Worker for better isolation and performance
2. **Permission Control**: Limit service permissions to minimize security risks
3. **JWT Caching**: Consider implementing JWT token caching for high-traffic scenarios
4. **Service Building**: Use build commands to pre-compile TypeScript services
## 🛣️ Roadmap
- [ ] **Service Metrics** - Built-in monitoring and metrics collection
- [ ] **WebSocket Support** - Real-time communication support
