The latest in JavaScript and cross-platform tools

Node v18.11.0, @nodejs
Highlights of this release:
  • A --watch mode where files are watched for changes (think nodemon)
  • Method .readlines() of FileHandles
  • util.parseArgs() supports default values for options.
The new watch mode is used as follows:
node --watch index.js
node --watch-path=./src --watch-path=./tests index.js  

Node.js reruns the entry point module whenever the watched files change.

Caveat for --watch-path: “This option is only supported on macOS and Windows.”

Rollup 3
  • First-class support for import assertions.
  • Better defaults for interoperation with ESM on Node.js.
Rollup’s website explains how to migrate to Rollup 3.

nvm v0.39.2
  • Improved performance

What is pnpm and is it really so fast and space-efficient?
Quoting the blog post: “In this post, I’d like to talk about what sets pnpm apart from other package managers – and why we need package managers at all.”
