Key Differences between Node.js vs Nginx

Answer 1

Both Node.js vs Nginx are popular choices in the market; let us discuss some of the major Differences Between Nginx vs Node.js:

1. In Node.js, a simple model of event-driven programming exists to finish the task using call back functions whereas in Nginx uses event-driven mechanism rather than using threads to handle multiple requests.
2. In Node.js, vertical scaling is not supported to increase the number of CPU cores in a machine whereas Nginx is able to handle a very large number of concurrent user requests with a very low memory capacity of around 2.5MB.
3. In Node.js, package management exists to use the different packages hosted on the npm site to use it by importing in applications projects whereas Nginx can handle static files, auto-indexing, index files, reverse proxy with caching.
4. In Node.js, the server runtime environment can be combined with a browser that supports a different kind of JSON databases whereas Nginx supports load balancing including health checks, virtual servers based on Name and IP addresses.
5. In Node.js, the runtime environment is registered with the existing operating system which notifies in case of any failure in call back functions whereas in Nginx has upgradable features without any connection loss with the client and also supports the mailing features like SMTP, POP3, IMAP, and TSL/SSL support and also IPv6 compatible.
6. In Node.js, the performance is an issue in terms of concurrent users where the response rate will be low in case of heavy load or concurrent user requests whereas Nginx’s main goal is to outperform the Apache web server in terms of performance especially in the case of heavy load and large concurrent user requests
7. In Node.js, its design itself is a single-threaded which allows only a single thread to handle concurrent requests and it is unable to make synchronous calls whereas in Nginx is a high-performance load balancer which is being used in most of the busiest websites over the world.
8. In Node.js, when making the requests to remote servers, the server requests and responses will be compressed using gzip whereas in Nginx processes the chains and filters which change the content such as similar to that of gzip process which is efficient and secure.
9. In Node.js, the serving content of a file over a webpage which consumes a lot of CPU memory compared to the same file in Nginx whereas in Nginx the CPU memory consumption is very less for the same file in Node.js which clearly indicates the saver in terms of memory.
10. In Node.js, a unified API exists which support the development of JavaScript stack applications using different server-side architectural patterns such as MVP, VMS, MT, MVVM etc., which allows it to reuse across both client-side and server-side environment whereas in Nginx all these features will be supported including the extra features such as firewall support, upgrading and configuring the applications at runtime without any client connection losses.
