What's new in Node.js 19?

A week ago, Node.js 19 was released Which includes the update of the V8 JavaScript engine to 10.7, and HTTP 1.1 KeepAlive enabled by default.

Important features of the release::

Watch mode

This is an experimental feature. It allows you to run node application with the --watch flag, which will restart the node process when it detects changes in the directory. This feature is useful for development. It is similar to the nodemon.


HTTP 1.1 KeepAlive enabled by default

HTTP 1.1 KeepAlive is enabled by default. This feature is useful for performance. It allows the TCP connection to remain open for multiple requests. This reduces the time required to set up new TCP connections. The default keep-alive duration is 5 seconds.


Stable WebCrypto

Stable WebCrypto is now available in Node.js. It is a standard cryptographic API for the web platform. It provides a secure and performant way to handle cryptographic operations. The WebCrypto API is available globally in Node.js. It can be accessed using crypto.webcrypto global object.


V8 JavaScript engine update to 10.7

The V8 engine is updated to version 10.7, which is part of Chromium 107. This version includes a new feature to the Javascript API.


Also, Node 14 is now in maintenance mode. It will be supported until April 2023. If you are using Node 14, you should upgrade to Node 16. Node 16 is the current LTS version. It will be supported until April 2024.

Git Concepts I Wish I Knew Years Ago

The most used technology by developers is not Javascript.

It's not Python or HTML.

It hardly even gets mentioned in interviews or listed as a pre-requisite for jobs.

I'm talking about Git and version control of course.

One does not simply learn git
