Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Having issues with passing a Typed object to a func... TS isn't warning when properties of said arg are the wrong type
Jest's out of the box config for TS doesn't do any type checking. You can integrate https://kulshekhar.github.io/ts-jest/ or you can call ‘tsc’ yourself separately

Is using Jest for anything other than React a bad idea?
ts-jest has had some strange performance issues and workarounds in the past, though I haven’t used it very recently so it might have fixed those by now.

Test-Driven Infrastructure Development with Pulumi and Jest
Since we're working with TypeScript, we can use ts-jest, which conveniently brings Jest along for the ride:

Improve your Testing with Custom Matchers in Jest
I want to save you from manually copying the snippets one by one, so here is a Gist with the complete test file. This can be easily executed with Jest (or ts-jest for TypeScript).

Setup Jest to React Typescript Vite project, also SWC (part 1)

Running Jest for Typescript CLI - unexpected token at import
Anyway, I ran into this exact error this morning setting up Jest for a TS script. I fixed it by just following the getting started instructions for Jest as well as ts-jest.

The best testing setup for frontends, with Playwright and NextJS
For this, we'll use chokidar - more specifically the chokidar-cli package. chokidar is probably the most useful file watching library for the nodejs ecosystem and it will serve us well.

Why Does 'Is-Number' Package Have 59M Weekly Downloads?
tailwindcss -> chokidar -> braces -> fill-range -> to-regex-range -> is-number
is-number was first published 9 years ago, when these kind of micro-packages were in vogue. braces was added as a dependency to chokidar over 6 years ago [1]. And if it ain't broke, don't fix it. I don't think the average JS dev today is going out and pulling in these deps.

How nodemon works?
The watching magic is really in the https://www.npmjs.com/package/chokidar library

Dart 3.1 and a retrospective on functional style programming in Dart
> It’s typical to listen to this stream of events and use chained if-else statements to determine an action based on the type of the events that occur.
You'd think something like directory watching would have a clear set of events that would make nice objects with consistent meanings, but in my experience file watching gets crazy complicated, and can have all sorts of edge cases.
Just take a looked here for all the various edge cases that crop up: https://github.com/paulmillr/chokidar/issues
Then you have linux, windows, macos, and maybe you want to abstract over some underlying implementation like chokidar vs fb/watchman vs webpack/watchpack. Every new OS release could also cause things to change.
So usually its going to be a bunch of if-else statements hacked together to get around edge cases, and have to be revisited later on.
Any attempt to abstract this into objects, just obfuscates things. And OO forces you to name things, when in fact they might be un-nameable. `FileSystemModifyEventExceptWhenXAndYAndSometimesZ`.
The behavior might rely on a series of events together, so the object hierarchy must be re-worked.
OO has this rosy idea that we just have to come up with the perfect hierarchy, but things change in unexpected ways, and everything must have a descriptive noun.

Is there anyway to auto reload the browser page when using express?
Next, you can use a library like chokidar to listen for changes in your source directory. Create a ws server, and whenever a file changes, send a message.

How does nodemon works under the hood?
As another has mentioned, nodemon uses chokidar under the hood for the actual file watching part.

Turbowatch – Extremely fast alternative to Nodemon
At the end of the day, ironically, Nodemon does not even implement file watching functionality. It is a thin wrapper around chokidar (see source code), and the way it is being used is neither efficient (CPU and your battery usage) or performant. So it is not a false argument, just perhaps not the most appealing.
