Step 1

Mustache Nginx Template Compiler

3 key tasks

Define parameterized Mustache template for Nginx reverse proxy server blocks.

Key Implementation Tasks

Define template containing domain, upstream port, and SSL directives
Render string output using Mustache package
Inject standard proxy headers (Host, X-Real-IP)

src/generator.ts

import mustache from 'mustache';

export interface ProxyConfig {
  domain: string;
  upstreamPort: number;
  enableSSL: boolean;
  certPath?: string;
}

const template = `
server {
    listen 80;
    server_name {{domain}};

    {{#enableSSL}}
    listen 443 ssl;
    ssl_certificate {{certPath}}/fullchain.pem;
    ssl_certificate_key {{certPath}}/privkey.pem;
    {{/enableSSL}}

    location / {
        proxy_pass http://127.0.0.1:{{upstreamPort}};
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }
}
`;

export function generateConfig(config: ProxyConfig): string {
  return mustache.render(template, config);
}

Pro Tip: Always include proxy_set_header Host $host to prevent backend routing issues.

Config File Writer & Directory Manager

Step 3

Live Nginx Syntax Validation Runner

Step 4

Automated Let's Encrypt SSL Integration

3 key tasks

Common Challenges & Debugging Solutions

Real issues students hit during development and how to troubleshoot them fast.

Deployment

Broken Nginx Config Crashes Web Server

Issue: Syntactically invalid generated configs break Nginx when reloaded, taking all existing sites offline.

Fix Solution:Execute sudo nginx -t prior to running reload, aborting if exit code is non-zero.

Environment Variables

Permission Denied on /etc/nginx File Writes

Issue: Script fails with EACCES error when writing configuration files.

Fix Solution:Run utility script with sudo rights or grant specific write permissions on target directory.

API Errors

Rate Limit Exhaustion on Let's Encrypt API

Issue: Repeated test runs hit Let's Encrypt 5 certs per week rate limit.

Fix Solution:Pass --staging flag to Certbot during development and testing.
