6 Major Features of Node.js 19
Details of Node.js 19 new features, including experimental node watch mode and HTTP(S)/1.1 KeepAlive by default
Node.js major release is rolled out every six months. The new release becomes the Current release for six months, which gives library authors time to add support for them.
After six months, odd-numbered releases, such as 19, become unsupported, and even-numbered releases, such as 18, move to the Active LTS (long-term support) status and are ready for general use.
LTS release typically guarantees that critical bugs will be fixed for a total of 30 months. Production applications should only use Active LTS or Maintenance LTS releases.
Node.js 19 was released on October 18, 2022. It becomes the Current release. It comes with 6 major features:
- Experimental node watch mode
- HTTP(S)/1.1 KeepAlive by default
- Stable WebCrypto
- Custom ESM resolution adjustments
- Dropped DTrace/SystemTap/ETW support
- V8 JavaScript engine is updated to V8 10.7
