Nginx and Node.js are powerful instruments for constructing network applications; however, their roles & operate differently. The significant difference between the two are:

1. Node.js employs a basic event-driven programming model with callback functions to execute tasks, while Nginx utilizes an event-driven mechanism instead of threads to manage numerous requests.
2. Nginx operates as a web server employing an event-driven, asynchronous structure to manage multiple concurrent connections without creating individual threads or processes for each. In contrast, Node.js functions as a JavaScript runtime, employing a single-threaded, event-driven architecture to handle multiple concurrent connections proficiently.
3. Nginx serves as a web server and reverse proxy, capable of directing incoming requests to alternate servers according to a defined set of regulations. Conversely, Node.js functions as a JavaScript runtime, allowing developers to construct personalized server-side logic for managing incoming requests.
4. Nginx can be a load balancer and offers SSL/TLS encryption and decryption. On the other hand, Node.js doesn't encompass these functionalities, necessitating adding extra tools or modules to incorporate them.
5. Within Node.js, the runtime environment establishes communication with the existing operating system, enabling notifications during callback function failures. In contrast, Nginx boasts upgradeable attributes that facilitate updates without disrupting client connections. Moreover, Nginx encompasses diverse mail-related functionalities encompassing SMTP, POP3, IMAP, and TLS/SSL support. It further maintains compatibility with IPv6.
6. Node.js offers a cohesive API for crafting JavaScript stack apps with various server-side patterns like MVP, VMS, MT, and MVVM, allowing reuse on both client and server ends. In contrast, Nginx supports these aspects and extras like firewalls, runtime upgrades, and configurations without interrupting client connections.

In conclusion, Nginx primarily serves web content, balances loads, and acts as a reverse proxy for HTTP, TCP, and UDP servers. Conversely, Node.js is predominantly utilized for creating network applications using JavaScript. They can work together, with Nginx functioning as a reverse proxy for Node.js apps.
