Looking to develop real-time web applications?, a popular JavaScript library, can help! By providing both client-side and server-side libraries for two-way, real-time communication, enables seamless communication between servers and web clients. While the APIs for both libraries are similar and the user interfaces are comparable, heavily relies on the WebSocket protocol with polling as a backup. Leveraging the WebSocket wrapper, it broadcasts to multiple sockets and stores data for each client. If you need programming that works in real time, a real-time application (RTA) might be what you’re looking for. Examples of use cases for real-time applications include:

  • Chatting apps like WhatsApp and Facebook Messenger are popular instant messaging examples. These apps don’t require any page reload to see new messages as they come in.
  • Push notifications are alerts from Facebook that pop up on your device, letting you know when you’ve been tagged in a photo or received a new message.
  • Real-time collaborative computing programs like Google Docs allow teams to work together on the same documents simultaneously and view each other’s updates in real time. This category also includes real-time games such as Counter-Strike and Call of Duty.
  • Industry leaders such as Microsoft Office, Yammer, and Zendesk rely on’s numerous capabilities, including instant chat, real-time analytics, and document collaboration. uses to establish a connection between the client and server and exchange data. operates at a low level and is hidden from view. Both the server and client use and connection management is handled transparently by The system also automatically updates to WebSocket if available. The protocol used by is exclusive to real-time transport and operates on top of existing protocols. However, a WebSocket server using cannot connect to a client using a different protocol like Long Polling Comet, and vice versa. As a result, many software companies are seeking developers with knowledge of the protocol.

  • Although has a polling backup method, its primary mode of communication is the WebSocket protocol. It can also be used as a WebSocket wrapper, but it offers additional features like broadcasting to multiple sockets and storing client-specific data.
  • While is known for its real-time communication capabilities, it does have limitations when it comes to WebSocket transport. appends additional information to each packet when using WebSocket, rendering the two protocols incompatible. This means that a WebSocket client cannot connect with a client, and vice versa.
  • With, you can attach an acknowledgement (also known as a callback) to any event. When triggered remotely, it invokes a local callback with specified arguments to be executed.
  • Callbacks are useful because they allow you to add local context to an event without relying on wired communication. Typically, the context is closed by the callback function. When the invocation is triggered, you can use the context to determine the next steps to take.
  • played a pivotal role in boosting the popularity of Node.js. The evolution and Engine extraction are major steps forward for, which has enabled new approaches in the Node.js ecosystem.
  • is a valuable tool for developers who require bi-directional socket connections between clients and servers. It makes building even basic applications such as chat rooms effortless. can simplify your workflow and provide fallback options for unsupported clients. is compatible with popular frameworks such as React, Flutter, Backbone.js, Angular 2, and Gatsby. It relies on to implement cross-browser/cross-device bi-directional communication, which provides with a range of features:

  • is capable of establishing a secure connection despite the existence of proxies, load balancers, personal firewalls, and antivirus software.
  • By default, the client library will keep attempting to reconnect indefinitely until it is able to connect to the server. This behavior can be stopped explicitly through the code.
  • When a disconnection occurs, this feature notifies both the server and the client.
  • Thanks to its support for multiplexing, can allow multiple communication channels to utilize the same physical connection.
  • supports binary streaming, allowing you to transmit any serializable binary data such as Array Buffers, Blobs, and more. possesses specific essential characteristics facilitates two-way, event-driven real-time communication while prioritizing reliability and speed. It is compatible with any system, browser, or device. The system is composed of a server written in Node.js and client libraries written in JavaScript. Other languages such as:

  • Java
  • C++
  • Swift
  • Dart
  • Python
  • .Net

Essential Characteristics

Analytics within the process

The data is presented to the client as live statistics, graphical representations, or logs.

Real-Time Binary Data

Version 1.0 allows for the transmission of any media file, including but not limited to images, sounds, and videos.

Real-Time Conversations and Instant Messaging (IM) allows you to create a messaging platform with just a few lines of code, such as the “Hello IO’s world” app.
