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.

Converting class based components into functional ones
You can convert the “easy” render-only class components to function components using the pure-component codemod.

Front-end Guide
Developer Experience - There are a number of tools that improves the development experience with React. React Developer Tools is a browser extension that allows you to inspect your component, view and manipulate its props and state. Hot reloading with webpack allows you to view changes to your code in your browser, without you having to refresh the browser. Front end development involves a lot of tweaking code, saving and then refreshing the browser. Hot reloading helps you by eliminating the last step. When there are library updates, Facebook provides codemod scripts to help you migrate your code to the new APIs. This makes the upgrading process relatively pain-free. Kudos to the Facebook team for their dedication in making the development experience with React great.

A new way to ship Codemods
Like most popular libraries, e.g. React, Next.js and more, which provide codemods to help move their huge user base across versions, we needed a bespoke and fairly simple CLI wrapper of jscodeshift, that would provide a means of publishing, downloading and running codemods. So we created a custom 'codemod-cli', our first piece of internal codemod infrastructure.

[AskJS] How do you release libraries updates with breaking changes?
Codemods - providing automated tooling to change old patterns to new ones can go a long way in helping drive adoption of the new version. The most notable example of doing this is react-codemod (many other examples exist)

All about Abstract Syntax Tree
Sometimes you need to migrate from one version of a library to another, for example, when React has updated to version 15.5 the PropTypes has moved to different package and the react-developers provides codemod for migration.

Modern JavaScript:Everything you missed over the last 10 years(ECMAScript 2020)
Can you point me towards examples of the usage of AST rewriting tools that are actively being used by open-source library maintainers in other ecosystems to help their consumers do upgrades in large code-bases (e.g. I can see that `clang` has AST tooling, but I don't see examples online of this being widely used: https://devblogs.microsoft.com/cppblog/exploring-clang-tooli...).
Within the JavaScript ecosystem this is quite popular (1. https://github.com/reactjs/react-codemod; 2. https://github.com/mui-org/material-ui/tree/HEAD/packages/ma... 3. https://github.com/emotion-js/emotion/tree/main/packages/esl... etc.) Teams that maintain huge codebases have tooling to safely automate their upgrades and the best library maintainers provide their consumers with these AST transformations.

How are folks feeling about the React team's push toward server components?
dang, I never thought about this implication, and I googled the emotionjs repo there's a currently-active open issue regarding this https://github.com/emotion-js/emotion/issues/2928

I created a Zero-Runtime CSS-in-JS Library Compatible with Next.js App Router and RSC
Over my years of working with React, I’ve loved using CSS-in-JS libraries like Emotion and Styled-components. However, their inherent performance overhead from injecting CSS at runtime and their incompatibility with the latest Next.js features such as App Router and React Server Components (RSC) have always been a nagging issue for me.

Next.js App Directory Architecture First Impressions
An early difficulty I encountered was using UI component libraries like Mantine and Material UI in the new architecture. After looking through some GitHub issues, the culprit is Emotion, a package many component libraries rely on that does not support server rendering.

CSS Style Guide for Web Dev?
In general I recommend using styled-components or emotion. These directly attach CSS to your components in a scoped way so that your CSS files aren’t stepping on each other’s toes all the time and make sure styling is colocated with the component.

Server Components
I ran into this problem as well. The root cause as I understand it is emotion: https://github.com/emotion-js/emotion/issues/2928
