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.”

Highlights:

• First-class support for import assertions.
• Better defaults for interoperation with ESM on Node.js.

Highlights:

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.”
