CometD vs Push.js: What are the differences?

Introduction: When it comes to real-time web messaging and notification systems, CometD and Push.js are popular choices. Understanding the key differences between these two technologies can help in deciding which one best fits the requirements of a web project.

Communication Protocol: CometD uses the Bayeux protocol for communication, which is based on HTTP long polling and WebSockets, providing a full-duplex communication channel. On the other hand, Push.js primarily focuses on using the simpler and more lightweight HTTP long polling approach for delivering real-time notifications to clients.
Client-Side Library: CometD provides a comprehensive JavaScript client library that enables easy integration with various web applications and frameworks. In contrast, Push.js is a lightweight library built specifically for handling client-side push notifications without the complexities of a full-fledged messaging system like CometD.
Scalability and Performance: CometD is more suitable for high-demand applications requiring high scalability and performance due to its support for multiple transport mechanisms and server clustering capabilities. Push.js, while efficient for basic push notification needs, may not be as scalable or performant as CometD in demanding scenarios.
Server-Side Implementation: CometD requires server-side components to handle message routing and data synchronization, making it more robust but also more complex to set up and maintain. Push.js, on the other hand, relies on simpler server-side logic for sending notifications to clients, making it more lightweight but potentially limiting in terms of advanced features.
Ease of Integration: Push.js is easier to integrate into existing web applications, especially those requiring straightforward push notification functionalities, thanks to its minimalist design and easy setup process. CometD, while powerful, may require more effort to seamlessly integrate into complex web architectures and frameworks.

In Summary, the key differences between CometD and Push.js lie in their communication protocols, client-side libraries, scalability, server-side implementations, and ease of integration, each catering to different needs in the realm of real-time web messaging and notifications.

Detailed Comparison

CometD	Push.js
It is a web server to push data to a browser, without the browser explicitly requesting it. It is an umbrella term, encompassing multiple techniques for achieving this interaction.	Push is the fastest way to get up and running with Javascript desktop notifications. A fairly new addition to the official specification, the Notification API allows modern browsers such as Chrome, Safari, and IE 9+ to push notifications to a user's desktop. Push acts as a cross-browser solution to this API, falling back to use older implementations if the user's browser does not support the new API.

What are some alternatives to CometD, Push.js?

NGINX

nginx [engine x] is an HTTP and reverse proxy server, as well as a mail proxy server, written by Igor Sysoev. According to Netcraft nginx served or proxied 30.46% of the top million busiest sites in Jan 2018.

Firebase

Firebase is a cloud service designed to power real-time, collaborative applications. Simply add the Firebase library to your application to gain access to a shared data structure; any changes you make to that data are automatically synchronized with the Firebase cloud and with other clients within milliseconds.

Apache HTTP Server

The Apache HTTP Server is a powerful and flexible HTTP/1.1 compliant web server. Originally designed as a replacement for the NCSA HTTP Server, it has grown to be the most popular web server on the Internet.

Socket.IO

It enables real-time bidirectional event-based communication. It works on every platform, browser or device, focusing equally on reliability and speed.

Unicorn

Unicorn is an HTTP server for Rack applications designed to only serve fast clients on low-latency, high-bandwidth connections and take advantage of features in Unix/Unix-like kernels. Slow clients should only be served by placing a reverse proxy capable of fully buffering both the the request and response in between Unicorn and slow clients.

PubNub

PubNub makes it easy for you to add real-time capabilities to your apps, without worrying about the infrastructure. Build apps that allow your users to engage in real-time across mobile, browser, desktop and server.

Microsoft IIS

Internet Information Services (IIS) for Windows Server is a flexible, secure and manageable Web server for hosting anything on the Web. From media streaming to web applications, IIS's scalable and open architecture is ready to handle the most demanding tasks.

Pusher

Pusher is the category leader in delightful APIs for app developers building communication and collaboration features.

Apache Tomcat

Apache Tomcat powers numerous large-scale, mission-critical web applications across a diverse range of industries and organizations.

Passenger

Phusion Passenger is a web server and application server, designed to be fast, robust and lightweight. It takes a lot of complexity out of deploying web apps, adds powerful enterprise-grade features that are useful in production, and makes administration much easier and less complex.
