Socket.io version 4.8.0 represents the latest iteration of this popular Node.js real-time framework, succeeding version 4.7.5. Both versions maintain the core functionality as a server-side solution for enabling real-time, bi-directional communication between web clients and servers. Developers relying on features like cors, debug, accepts, base64id, socket.io-parser, and socket.io-adapter will find these dependencies consistent across both versions. A key difference lies in the engine.io dependency, which jumps from version 6.5.2 in 4.7.5 to version 6.6.0 in 4.8.0, potentially bringing performance enhancements and bug fixes under the hood related to Engine.IO's transport mechanisms.
Version 4.7.5 includes a suite of development dependencies such as nyc for coverage reporting, tsd for type definitions, mocha for testing, and typescript for type checking which are instead missing in the newer release. Version 4.8.0 has an increased unpacked size and file count, suggesting additions or modifications in the core code or assets. Developers should note the discrepancy in the repository URL: 4.7.5 uses git:// while 4.8.0 utilizes git+https://. Release dates highlight the freshness of 4.8.0 released on September 21, 2024, compared to 4.7.5 released on March 14, 2024. Potential users are encouraged to review the change logs for engine.io version 6.6.0 that will bring information about precise fixes and performance improvements.
