XyPriss Nginx Controller - Simplifie la gestion de Nginx et SSL.

Overview

XyNginC (XyPriss Nginx Controller) automates Nginx reverse proxy configuration, SSL certificate management, and provides optimized, production-ready configs for security, performance, and best practices. It eliminates manual Nginx editing, simplifying XyPriss deployment to just a few lines of TypeScript. Check out the demo project on GitHub.

Key Features

• Automated Reverse Proxy: Maps domains to local ports seamlessly.
• One-Command SSL: Integrated Let's Encrypt and Certbot support for automatic HTTPS.
• Automatic Nginx Reload: Applies configuration changes without manual service restarts.
• Multi-Domain Support: Manages multiple domains and subdomains within a single configuration.
• Optimized Configuration: Generates production-ready Nginx configuration files.
• High Performance: Core logic executed via a Rust-based CLI for speed and reliability.
• Type Safety: Full TypeScript support with comprehensive type definitions.

Installation

For detailed installation instructions, please refer to the Installation Guide. For building from source (custom architectures), see the Build Guide.

XyNginC is designed for production environments running on Linux. We strongly recommend using Ubuntu on a Virtual Private Server (VPS) for the best security and stability.

Quick Start

Basic Configuration

Integrate XyNginC into your XyPriss server:

import { createServer } from "xypriss";
import XNCP from "xynginc";

const app = createServer({
  plugins: {
    register: [
      XNCP({
        domains: [
          {
            domain: "api.example.com",
            port: 3000,
            ssl: true,
            email: "[email protected]",
          },
        ],
      }),
    ],
  },
});

app.start();

Multiple Domains Configuration

Configure multiple environments or services simultaneously:

XNCP({
  domains: [
    {
      domain: "api.example.com",
      port: 3000,
      ssl: true,
      email: "[email protected]",
    },
    {
      domain: "admin.example.com",
      port: 3001,
      ssl: true,
      email: "[email protected]",
    },
    {
      domain: "dev.example.com",
      port: 3002,
      ssl: false,
    },
  ],
  autoReload: true,
});

Dynamic Management

Manage domains programmatically at runtime:

app.start(undefined, async () => {
  // Add a new domain
  await app.xynginc.addDomain(
    "new.example.com",
    4000,
    true,
    "[email protected]"
  );

  // List configured domains
  const domains = await app.xynginc.listDomains();
  console.log("Configured domains:", domains);

  // Validate XCNP configuration
  const isValid = await app.xynginc.test();

  // Reload XyNginC service
  await app.xynginc.reload();

  // Remove a domain
  await app.xynginc.removeDomain("old.example.com");
});

API Reference

Plugin Options

interface XyNginCPluginOptions {
  /** List of domains to configure */
  domains: Array<{
    domain: string; // Domain name (e.g., api.example.com)
    port: number; // Local port to proxy (e.g., 3000)
    ssl?: boolean; // Enable SSL via Let's Encrypt
    email?: string; // Email for Let's Encrypt registration (required if ssl=true)
  }>;

  /** Automatically reload Nginx after configuration changes (default: true) */
  autoReload?: boolean;

  /** Custom path to the xynginc binary - recommended */
  binaryPath?: string;

  /** Automatically download the binary if missing (default: true) */
  autoDownload?: boolean;

  /** Specific GitHub release version to download (default: "latest") */
  version?: string;
}

Server Methods

The following methods are exposed on server.xynginc after the plugin is registered:

// Add a domain configuration
await server.xynginc.addDomain(
  domain: string,
  port: number,
  ssl: boolean,
  email?: string
): Promise<void>

// Remove a domain configuration
await server.xynginc.removeDomain(domain: string): Promise<void>

// List all configured domains
await server.xynginc.listDomains(): Promise<string[]>

// Reload XyNginC service
await server.xynginc.reload(): Promise<void>

// Test XyNginC configuration validity
await server.xynginc.test(): Promise<boolean>

// Get status of managed sites
await server.xynginc.status(): Promise<string>

CLI Usage

The xynginc command-line interface allows for direct management without the Node.js application context.

# Check prerequisites
sudo xynginc check

# Add a domain
sudo xynginc add --domain api.example.com --port 3000 --ssl --email [email protected]

# List domains
sudo xynginc list

# Apply configuration from a JSON file
sudo xynginc apply --config config.json

# Test Nginx configuration
sudo xynginc test

# Reload Nginx
sudo xynginc reload

# Remove a domain
sudo xynginc remove api.example.com

# View status
sudo xynginc status

Configuration File Example

{
  "domains": [
    {
      "domain": "api.example.com",
      "port": 3000,
      "ssl": true,
      "email": "[email protected]"
    }
  ],
  "auto_reload": true
}

Architecture

The system operates through a three-tier architecture:

1. XyPriss Application: The Node.js application running the server.
2. XyNginC Plugin: A TypeScript wrapper that interfaces with the application and manages the binary.
3. XyNginC Binary: A Rust-based CLI tool that performs system-level operations (Nginx configuration, Certbot execution).

Security Considerations

XyNginC requires elevated privileges to perform the following actions:

• Writing to /etc/nginx/sites-available/
• Creating symbolic links in /etc/nginx/sites-enabled/
• Executing certbot for SSL certificate generation
• Reloading the Nginx service

Note: Ensure your XyPriss server is started with sudo privileges when using this plugin, or configure sudoers to allow specific commands for the user.

Troubleshooting

Binary Not Found

If the binary fails to download automatically:

# Manually trigger postinstall
npm run postinstall

# Or specify the path manually in options
XNCP({
  binaryPath: "/usr/local/bin/xynginc",
  autoDownload: false,
})

Permission Denied

If you encounter permission errors:

# Run with sudo
sudo node server.js

Certbot Failure

If SSL generation fails:

1. Verify DNS propagation: dig api.example.com
2. Ensure firewall allows traffic on ports 80 and 443:

   sudo ufw allow 80
   sudo ufw allow 443
