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.

The best testing strategies for frontends
Probably Enzyme was the first to popularize component testing in React by doing shallow rendering and expecting some things to be there in the React component tree. Then React Testing library came and took component testing to a whole new level.

Testing React Components: A Comprehensive Overview of Testing Libraries
Enzyme is another popular testing utility for React. It allows you to manipulate and traverse React components' output, making it easier to write comprehensive tests.

Speeding up the JavaScript ecosystem – Polyfills gone rogue
ljharb is an extremely interesting person. There’s no doubting the positive impact he’s had on the OSS community and the work he’s done.
However, there are some things he does that are incomprehensible.
For example, Enzyme. Over three years ago this issue was opened for Enzyme on React 17: https://github.com/enzymejs/enzyme/issues/2429
Nothing moved for a while, and I think he said something along the lines of “if you want React 17 support, stop complaining and help”. So the community got involved. There are multiple PRs adding React 17 support. Many unofficial React 17 adapters. A lot of people have put a lot of work into this, ensuring compatibility, coverage etc. Yet to this day, none of them have been merged. Eg https://github.com/enzymejs/enzyme/pull/2564
Given the amount of time that has passed, and the work the community has put in, something is amiss. It feels like he’s now intentionally avoiding React 17+ support. But why? I don’t understand why someone would ask for help then ignore the help when it comes in. That isn’t much better than the swathe of rude/entitled comments he was getting on the issue before he locked it.
I ended up migrating to RTL, but this made many of my tests more complicated (especially compared to shallow rendering).

How To Scale Your React Applications
One way to do this is by writing tests for your React components. Tools like Jest and Enzyme make it easy to test your component's behavior, rendering output, and state changes. By writing tests for your components, you can ensure that they behave as expected and prevent issues before they reach production.

How to Confidently Write Unit Tests using React Testing Library
So If you have experience with enzyme testing, where you might be checking the value of state once you click any button or you might be checking the prop value If something changes.

Difference Between JEST and Enzyme?
Enzyme offers two types of API for shallow rendering and full rendering. Both are preferred for different test scenarios and functionalities.

Testing with Jest and React Testing Library
At Visa, I was writing unit tests for a Next.js project using components designed with Chakra UI. That's where React Testing Library came in handy. Unlike other solutions like Enzyme, I did not have to worry about the application snapshot but could instead focus on each UI element, its expected behaviour and the data it would render upon user interactions.

Superset: Testing and Enzyme to RTL conversion
Superset uses Jest and React Testing Library (RTL) to write unit and integration tests. In the past we used Enzyme, but now that we're currently converting all of our class components to functional components, Enzyme cannot support our testing needs. Since RTL is better for testing functional components, we're converting all of our test files to RTL. This can be quite a learning curve - I've gone through a lot of the process so I'd like to share what I've learned so far.

Some Very Cool (Underrated maybe) React Libraries
React Query: This library makes it easy to manage data in your React applications, from fetching to caching and updating data. It offers a simple, powerful, and flexible API for handling data and keeping your UI in sync with your data. https://github.com/tannerlinsley/react-query

Do I need a fetching library in React?
useQuery (react-query) (+) all from above (+) even more features (-) more complex, even the examples are complex, has more aggressive defaults (re-fetching every 2s)

React hooks for 28 RxJS operators
React Query is the gold standard for using async data declaratively with hooks. I ended up needing to modify even my simple useTimer hook to work more like useQuery to take multiple keys in order to work as an inner observable for other operators.

Goodbye, useEffect - Reactathon 2022
For most situations, I would recommend using a library like React Query. It handles a lot of common data-fetching boiler plate and already accounts for this useEffect() issue. Also, it supports Suspense if you want to use that.

Managing application cache with react-query, and code generation.
At this point, I want to move on to the react-query cache management library. Give a brief overview and see how you can improve your developer experience with cache using this library.
-
When to use a hook, and when to use a service?
There isn't the "service" concept in React. If you need to send off data you can just do so with fetch. If you need to load data and cache it so it can be used across components and unmounts, then something like react-query is what I'd recommend. But it's basically a combination of React Context, useEffect, and useState to manage the cache and lifecycle of a request.
