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.

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.

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.

How to Add Firebase Authentication To Your NodeJS App
There are several testing approaches you can take to ascertain the functionality of the auth API. One way would be to automate the testing using unit tests with tools like Jest and Supertest. Alternatively, you can make use of API clients like Postman or the Thunder Client VS Code extension to test the API.

JS Toolbox 2024: Bundlers and Test Frameworks
Jest, created and maintained by Facebook, is a JavaScript testing framework with a focus on simplicity. It is often recognized for its zero-configuration setup and seamless integration, especially with React applications, making it a favored choice for developers in both small-scale projects and large enterprise applications.

Unit Testing Expo Apps With Jest
console.error Jest encountered an unexpected token Jest failed to parse a file. This happens e.g. when your code or its dependencies use non-standard JavaScript syntax, or when Jest is not configured to support such syntax. Out of the box Jest supports Babel, which will be used to transform your files into valid JS based on your Babel configuration. By default "node\_modules" folder is ignored by transformers. Here's what you can do: • If you are trying to use ECMAScript Modules, see https://jestjs.io/docs/ecmascript-modules for how to enable it. • If you are trying to use TypeScript, see https://jestjs.io/docs/getting-started#using-typescript • To have some of your "node\_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config. • If you need a custom transformation specify a "transform" option in your config. • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option. You'll find more details and examples of these config options in the docs: https://jestjs.io/docs/configuration For information about custom transformations, see: https://jestjs.io/docs/code-transformation

Painless CLI integration testing
We use Jest Framework for testing. Jest is not a dogma, and, of course, in its place can be any other test runner, such as Mocha or Ava. Let's focus on tests. I'll provide a short example because I don’t want to waste your time. You can find the full version here. It's crucial to read the comments in the code below. Let's go!

What is integration testing in UI/Front End?
Jest has long been my favorite got to test runner when it comes to UI unit and integration testing. With tools like React Testing Library (Testing Library framework for React) you get the benefit of very easy to write and maintain tests, as well as a quick and efficient way to run our tests.
