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.

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.

Jest is a well-regarded JavaScript testing framework primarily designed for React applications, although its utility extends to projects using Babel, JavaScript, Node, Angular, and Vue. Created by Facebook, Jest emphasizes ensuring the correctness of JavaScript codebases. It allows developers to write tests with a familiar, feature-rich API, making the testing process swift and enjoyable.

Use CSS Variables to style react components on demand
Without any adding any dependencies you can connect react props to raw css at runtime with nothing but css variables (aka "custom properties"). If you add CSS modules on top you don't have to worry about affecting the global scope so components created in this way can be truly modular and transferrable. I use this with vite.

Ask HN: How do we include JavaScript scripts in a browser these days?
it says in their docs that they recommend Vite https://vitejs.dev/
it goes like this.
1. you create a repo folder, you cd into it.
2. you create a client template using vite which can be plain typescript, or uses frameworks such as react or vue, at https://vitejs.dev/guide/
3. you cd in that client directory, you npm install, then you npm run dev, it should show you that it works at localhost:5173
4. you follow the instructions on your url, you do npm install @web3modal/wagmi @wagmi/core @wagmi/connectors viem
5. you follow the further instructions.
> It seems like this is for npm or yarn to pull from a remote repository maintained by @wagmi for instance. But then what?
you install the wagmi modules, then you import them in your js code, those code can run upon being loaded or upon user actions such as button clicks
> Do I just symlink to the node_modules directory somehow? Use browserify? Or these days I'd use webpack or whatever the cool kids are using these days?
no need for those. browserify is old school way of transpiling commonjs modules into browser-compatible modules. webpack is similar. vite replaces both webpack and browserify. vite also uses esbuild and swc under the hood which replaces babel.
> I totally get how node package management works ... for NODE. But all these client-side JS projects these days have docs that are clearly for the client-side but the ES2015 module examples they show seem to leave out all instructions for how to actually get the files there, as if it's obvious.
pretty much similar actually. except on client-side, you have src and dist folders. when you run "npm run build" vite will compile the src dir into dist dir. the outputs are the static files that you can serve with any http server such as npx serve, or caddy, or anything really.
> What gives? And finally, what exactly does "browserify" do these days, since I think Node supports both ES modules and and CJS modules? I also see sometimes UMD universal modules
vite supports both ecmascript modules and commonjs modules. but these days you'll just want to stick with ecmascript which makes your code consistently use import and export syntax, and you get the extra benefit of it working well with your vscode intellisense.
> In short, I'm a bit confused how to use package management properly with browsers in 2024: https://modern-web.dev/guides/going-buildless/es-modules/
if people want plain js there is unpkg.com and esm.sh way, but the vite route is the best for you as it's recommended and tested by the providers of your modules.
> And finally, if you answer this, can you spare a word about typescript? Do we still need to use Babel and Webpack together to transpile it to JS, and minify and tree-shake, or what?
I recommend typescript, as it gives you better type-safety and better intellisense, but it really depends. If you're new to it, it can slow you down at first. But as your project grows you'll eventually see the value of it. In vite there are options to scaffold your project in pure js or ts.

Exploring Advanced Tools in React Development
Vite is a blazing fast build tool that significantly improves the development experience for React applications. It leverages modern browser features such as native ES module imports to provide near-instantaneous development server startup and rapid hot module replacement (HMR) updates. This makes the development process incredibly smooth and efficient, especially for large-scale projects.
