Release notes

Package name: socket.io

  Dependencies

  • engine.io-client@~6.6.1 (no change)
  • ws@~8.17.1 (no change)
• 4.8.0 - 2024-09-21
  

  Features

  Custom transport implementations

  The transports option now accepts an array of transport implementations:

  import { io } from "socket.io-client";
  import { XHR, WebSocket } from "engine.io-client";

  const socket = io({
  transports: [XHR, WebSocket]
  });

  Here is the list of provided implementations:

  Transport	Description
  Fetch	HTTP long-polling based on the built-in fetch() method.
  NodeXHR	HTTP long-polling based on the XMLHttpRequest object provided by the xmlhttprequest-ssl package.
  XHR	HTTP long-polling based on the built-in XMLHttpRequest object.
  NodeWebSocket	WebSocket transport based on the WebSocket object provided by the ws package.
  WebSocket	WebSocket transport based on the built-in WebSocket object.
  WebTransport	WebTransport transport based on the built-in WebTransport object.

  Usage:

  Transport	browser	Node.js	Deno	Bun
  Fetch	✅	✅ (1)	✅	✅
  NodeXHR		✅	✅	✅
  XHR	✅
  NodeWebSocket		✅	✅	✅
  WebSocket	✅	✅ (2)	✅	✅
  WebTransport	✅	✅

  (1) since v18.0.0
  (2) since v21.0.0

  Added in f4d898e and b11763b.

  Test each low-level transports

  When setting the tryAllTransports option to true, if the first transport (usually, HTTP long-polling) fails, then the other transports will be tested too:

  import { io } from "socket.io-client";

  const socket = io({
  tryAllTransports: true
  });

  This feature is useful in two cases:

  • when HTTP long-polling is disabled on the server, or if CORS fails
  • when WebSocket is tested first (with transports: ["websocket", "polling"])

  The only potential downside is that the connection attempt could take more time in case of failure, as there have been reports of WebSocket connection errors taking several seconds before being detected (that's one reason for using HTTP long-polling first). That's why the option defaults to false for now.

  Added in 579b243.

  Bug Fixes

  • accept string | undefined as init argument (bis) (60c757f)
  • allow to manually stop the reconnection loop (13c6d2e)
  • close the engine upon decoding exception (04c8dd9)
  • do not send a packet on an expired connection (#5134) (8adcfbf)

• Version Bump: Upgrades the main socket.io dependency from 4.6.1 to 4.8.1.
• Transitive Dependency Updates: Includes updates to several underlying dependencies of socket.io, such as engine.io, engine.io-parser, and various @types packages.
• New Features/Fixes: Incorporates features and bug fixes from socket.io versions 4.7.x and 4.8.x, including new transport options and bug fixes mentioned in the release notes.

Code Review

This PR from Snyk updates socket.io from 4.6.1 to 4.8.1, primarily to address two high-severity security vulnerabilities. The changes are limited to package.json and package-lock.json and appear to be a standard and safe dependency upgrade. The update is minor and Snyk indicates no breaking changes. This is a recommended update for security reasons.

Summary of Findings

• Minor Node.js Engine Requirement Update: The updated socket.io (v4.8.1) and its dependency engine.io (v6.6.4) now require Node.js >=10.2.0, a slight increase from >=10.0.0. Given that Node.js 10.x is long past its end-of-life (EOL April 2021), this is highly unlikely to impact any modern deployment environment. This change was classified as low severity and not commented on directly due to review settings.
• Update to @types/node: Transitive dependencies have updated @types/node from v18.16.3 to v22.15.29. For this JavaScript project, this primarily affects developer tooling (like IntelliSense and type checking via JSDoc if used). While a significant version jump, it's generally beneficial for type accuracy and unlikely to cause runtime issues in a JavaScript project. This change was classified as low severity and not commented on directly due to review settings.

Merge Readiness

The pull request is well-defined, addresses important security vulnerabilities, and the changes are limited to dependency updates. Based on the information provided by Snyk and the nature of the version bump (minor, non-breaking), this PR appears ready for merging after standard testing procedures (e.g., CI checks, integration tests) pass. As an AI reviewer, I am not authorized to approve pull requests, but I recommend that this PR be merged to enhance the application's security. Please ensure your project's test suite covers the functionality relying on socket.io to catch any unexpected regressions, however unlikely.
