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 too many contexts - is it a problem?
Use jotai, or as someone else mentioned, zustand. React Context out of the box requires a very deliberate mental model due to a lack of tooling around selecting slices of state. This is why packages like react-context-selector exist: https://github.com/dai-shi/use-context-selector

Truly the best time to be a cs student
Unless I've missed it, context doesn't have selector IIRC. You'd have to use a third party solution useContextSelector

Tips for managing and organizing complex state with React context
you can always split out context state or use a library to help with rerender issues like https://github.com/dai-shi/use-context-selector, or just switch to jotai or something else if you want something more ergonomic or better design patterns.

ReactJs - Useless re-renders when a context changes - HOW TO SOLVE IT ?
If you don't want to swap out useContext, you could always use useContextSelector, which helps you limit what props in the context should rerender the component.

-
is Redux the first state management library you'll advise beginners to learn these days?
It wouldn't be clear to anyone learning Context API either. At least, not using official docs. Because Context API is not supposed for state management, and if you for some unknown reasons try to roll your own state management on top of it, you have to use tricky libraries to work around the issues resulting from such abuse.

What are some React Tricks/Tips for React Devs?
Any time anything in the context changes, any component that is consuming it will re-render. If you use it for frequently changed values, this library is needed to reduce unnecessary re-renders.

Inflist, an experiment using PureScript and React
Another technology I use regularly is Redux. But this time I wanted to manage the global state in a simpler and clearer way just using React hooks. I decided to go with a simple useReducer combined with theuseContextSelector hook which will avoid the whole application’s re-render caused by the native useContext hook.

Managing View State and Client-side Routing in SPAs
At JupiterOne, we've made a significant transition from a monolithic frontend to a distributed frontend architecture using microfrontends, powered by (single-spa-react)[https://single-spa.js.org/]. This architectural shift has brought many benefits, such as lazy loading sections of the app and accelerating our development cycle. However, like any significant change, it has also come with its set of challenges.

Micro frontend frameworks in 2024
Single-SPA Framework - One of the most popular choices. It has a large community behind it and offers robust routing and lifecycle management for microapps. Ref - https://single-spa.js.org/

⏰ It’s time to talk about Import Map, Micro Frontend, and Nx Monorepo
Joel Denning is the visionary behind single-spa, boasting profound insights into the true mechanics of the web and is, in my view, a pioneer in micro frontend architecture. I highly recommend checking the single-spa website and his YouTube channel. While the videos might appear dated at first glance, rest assured, Joel is ahead of his time, and the content remains incredibly relevant today.

Single-SPA and Svelte advices.
You got me curious and I found that single spa is something new to me - if I read https://github.com/single-spa/single-spa then I reckon you can use Svelte(Kit) in such framework - like you can use angular etc

Use web components for what they’re good at
I’ve actually done that “web components as the interoperability layer”!
It was this old angular 1.8 app with new features being written in angular-hybrid-ized angular 8. Ripping out angular-hybrid and separating the angular 1.8 routes from the modern angular routes was difficult, but now they were totally separate.
The only thing linking them together was an object with some RXJS streams in it for state, and a little in-house wrapper “app” who just loaded one component or another depending on the URL and a hash of routes for config. (I’d probably use SingleSPA [1] now. Same thing really.)
We could deploy them separately since the build just ends up being another JS file somewhere that just gets included with a script tag at runtime. No version bumping! No big mega build!
We started replacing the remaining “old” routes 1 by 1 with a “new” counter part. That was the easiest part, and went at a pace devs were comfortable with (fast enough) and business folk could tolerate. (modular enough to not HAVE to be done all at once)
Last I checked, the angular 1.8 stuff is gone years ago. :)

Building a Large Scale Micro-frontend Application.
Single-SPA and module federation are potent tools for building scalable micro-frontends. Single-spa provides a framework for building a modular front-end application. It allows lazy loading of micro-frontends, which helps improve the application's performance. In contrast, module federation enables communication and dependency sharing between different micro-frontends. It reduces code duplication, which can help with scaling an application.
