Node.js 19 is now available

The Node.js team has released Node.js 19, which updates the V8 JavaScript engine to version 10.7 and enables HTTP(s)/1.1 KeepAlive by default.

Version 10.7 of the V8 JavaScript engine adds to the JavaScript API the latest version of Intl.NumberFormat, which lets developers create a formatter instance that is reusable and that supports locale-aware number formatting. 

By having HTTP(s)/1.1 KeepAlive enabled by default, any outgoing connection will automatically use it and it will provide better throughput. This is because connections are reused. 

Other new features include:

  • Support for running the runtime in “watch” mode, which restarts the process if an imported file is changed
  • WebCrypto API is now stable
  • Removal of support for DTrace, SystemTap, and ETW
  • Removal of the –experimental-specifier-resolution flag 

According to the team, Node.js 19 will become the “Current” release line after Node.js 18 enters Long-Term Support at the end of the month, and it will remain that way through April 2023. 

“With over 1,150 commits since the last release, Node.js continues to improve along a broad spectrum of functionality. Improvements in connectivity, performance and throughput are important parts of Node.js 19. We’ve been working hard on making Node.js more secure and performant, and I believe we are getting better and better. If you’re in active deployment, Node.js 18 LTS is for you. If you’re interested in getting access to features early, Node.js 19 is ready,” said Rafael Gonzaga, Node.js Core member. “Many thanks to our open source contributors for making Node.js better and better.”

2022: The year of hybrid work

Remote work was once considered a luxury to many, but in 2020, it became a necessity for a large portion of the workforce, as the scary and unknown COVID-19 virus sickened and even took the lives of so many people around the world.  Some workers were able to thrive in a remote setting, while others felt isolated and struggled to keep up a balance between their work and home lives. Last year saw the availability of life-saving vaccines, so companies were able to start having the conversation about what to do next. Should they keep everyone remote? Should they go back to working in the office full time? Or should they do something in between? Enter hybrid work, which offers a mix of the two. A Fall 2021 study conducted by Google revealed that over 75% of survey respondents expect hybrid work to become a standard practice within their organization within the next three years.  Thus, two years after the world abruptly shifted to widespread adoption of remote work, we are dec...
