Stable WebCrypto

Adjustments in Custom ESM Resolution.

Node.js has discontinued its –experimental-specifier-resolution flag, yet we can still attain the same results through custom loaders.

DTrace/SystemTap/ETW Support Removed

In version 19.0.0, the team determined that the allocation of resources needed for DTrace/SystemTap/ETW was not worth it without a clear plan in place to maintain and update their support- thus they removed said provisions from this iteration. With much evaluation being done, the complexity associated with upkeep deemed it not worthwhile in comparison to other alternatives presently available.

Updated V8 JavaScript Engine to 10.7

Node.js is powered by the V8 engine, which allows for your JavaScript to be quickly interpreted and executed in a Node environment.

Developers can write JavaScript without any concern for whether their code is compatible with Linux, Windows, macOS or hardware running on x64, Arm or Power PC thanks to the V8 JavaScript engine – a runtime environment that enables the execution of JS code.

As V8 is crafted with C++, Node.js developers must guarantee its regular upkeep and growth across multiple hardware and operating system configurations.

llhttp 8.1.0

Node.js 19 has been released with the updated llhttp@8.1.0, offering a TypeScript implementation of http_parser to generate C source files for linking and compiling with Node.js or any other embedder’s program!

This parser is designed specifically for high-performance HTTP applications, and can parse requests as well as responses with remarkable speed.

The Node.js development team is perpetually striving to refine llhttp with contemporary API features and callbacks for consumers’ ultimate benefit.

npm 8.19.2

The NPM version included in the Node.js 18 and 19 lines are identical, yet this program was first released with Node.js 8.6.0 — meaning that continuing updates keep it up-to-date and modernized!

Platform Support

Node.js 19 brings significant updates and enhancements to the supported platforms, as opposed to its former release.’s prerequisites remain unchanged; however, any operating systems that have reached their end-of-life are no longer accepted by Node.js 19.
