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.

Migrating from Jest to Vitest for your React Application
Native code coverage via v8 or istanbul.
-
Testing Vue components the right way
Writing tests is essential, and knowing whether you test all the required cases for your logic is even more critical. The most common testing coverage tool is Istanbul, where you can see how well your tests exercise your code by lines, functions, and branches. Below is an example of how the test coverage report looks in your terminal:
-
Don't target 100% coverage
Here is a quote from istanbul, one of the most used code coverage tool:
-
Unit testing like a Hacker
Unit testing framework was already implemented, using Vitest so I started hacking by setting up a coverage provider to explicitly identify the covered/uncovered lines and mentioned this to the maintainer in the comments. I used Istanbul 🇹🇷 for this purpose.
-
Auto-Publish Your Test Coverage Report on GitHub Pages
Your project probably has a coverage report. If you’re using Jest as your unit test runner, generating a coverage report is embedded in it. It is done with Istanbul under the hood, which generates a nice HTML page presenting the entire project unit test coverage.

Dear Linux, Privileged Ports Must Die
> This is a rant written by someone with just enough understanding to be dangerous, but not quite enough wisdom to know why things are still the way they are. Most of the complaints raised are subtly inaccurate.
Author seems aware of CAP_NET_BIND_SERVICE: https://source.small-tech.org/site.js/app/-/issues/169 and https://github.com/istanbuljs/nyc/issues/1281 – the "side effects" are NodeJS explicitly checking for it, so that's a NodeJS thing and not a Linux thing.
Yet curiously it's completely unmentioned in this article, in spite that this is probably what started the author's dislike of privileged ports. I guess it was inconvenient as it got in the way of angrily ranting.

Comprehensive coverage Jest+Playwright in Next.js TS
This approach will create two json coverage files, which will be merged together by NYC. Therefore the results will be purely local. If You don't mind using online tools like Codecov or Coveralls for merging data from different tests, then go ahead and use them. They will probably also be more accurate. But if You still want to learn how to get coverage from E2E, then please read through

When developing in React, what do you find most frustrating or cumbersome?
https://istanbul.js.org/ measures how much of your code is covered by tests
-
Production Ready React
Jest uses a package called Istanbul to provide test coverage metrics such as statement, branch, function, and line coverage so that you can understand and enforce the quality of your test suite, providing more confidence in releases.

Aggregating Unit Test Coverage for All Monorepo’s Packages
So let’s see if nyc (the code coverage generator) can help with that. Hmm… this documentation seems interesting! So basically what I understand from it is that I need to collect all the reports from the different packages and then run the nyc report over it. The flow should be like this:

Add Step-up Authentication Using Angular and NestJS
Open the project up in your favorite IDE. Let's take a quick look at the project organization. The project has an Angular frontend and NestJS API backend housed in a Lerna monorepo. If you are curious about how to recreate the project, check out the repo's README file. I'll include all the npx commands, CLI commands, and the manual steps used to create the project.

Things I learned while building projects with NX
Lerna currently maintained by Nx team
- tsParticles 3.0.0 is out. Breaking changes ahead.

Nx 16.8 Release!!!
On Netlify's enterprise tier, approximately 46% of builds are monorepos, with the majority leveraging Nx and Lerna. Recognizing this trend, Netlify has focused on enhancing the setup and deployment experiences for monorepo projects. In particular they worked on an "automatic monorepo detection" feature. When you connect your project to GitHub, Netlify automatically detects if it's part of a monorepo, reads the relevant settings, and pre-configures your project. This eliminates the need for manual setup. This feature also extends to local development via the Netlify CLI.

Help with library implementation in a big webapp
This is the exact problem monorepos were born to solve. Not only will a monorepo let you share UI components, you'll be able to gradually add shared application logic as well (for instance, do all of your apps have their own logic for connecting to a database? you could roll that into a shared library with a monorepo). There are a lot of tools for accomplishing this in JS, but probably the most popular is lerna, which is built on top of NX (though lots of teams roll their own monorepo in nx without lerna, which IMO is a totally valid option).

How to Build and Publish Your First React NPM Package
To begin, you need to prepare your environment. A few ways to build a React package include tools like Bit, Storybook, Lerna, and TSDX. However, for this tutorial, you will use a zero-configuration bundler for tiny modules called Microbundle.

Utility for making sure that I'm using the right `@types/react`
If so, are you using a monorepo tool like Nx or Lerna? If not, start there and see if it solves your problem.

[AskJS] Is there a silver bullet for consuming Typescript libraries in a Monorepo?
I mean I don't know what your monorepo looks like, but for example infernojs (actually written with typescript) uses lerna, and lerna seems simpler than typescript references

Understanding npm Versioning
Tools for publishing, such as Lerna (when using the --conventional-commit flag), follow this convention when incrementing package versions and generating changelog files.
What are some alternatives?
turborepo - Incremental bundler and build system optimized for JavaScript and TypeScript, written in Rust – including Turborepo and Turbopack. [Moved to: https://github.com/vercel/turbo]
nx - Smart Monorepos · Fast CI
jest - Delightful JavaScript Testing.
changesets - 🦋 A way to manage your versioning and changelogs with a focus on monorepos
pnpm - Fast, disk space efficient package manager
istanbul - Yet another JS code coverage tool that computes statement, line, function and branch coverage with module loader hooks to transparently add coverage when running tests. Supports all JS coverage use cases including unit tests, server side functional tests and browser tests. Built for scale.
webpack - A bundler for javascript and friends. Packs many modules into a few bundled assets. Code Splitting allows for loading parts of the application on demand. Through "loaders", modules can be CommonJs, AMD, ES6 modules, CSS, Images, JSON, Coffeescript, LESS, ... and your custom stuff.
single-spa - The router for easy microfrontends
husky - Git hooks made easy 🐶 woof!
