create-react-library VS react-fiber-architecture

At first i thought that this was THE solution but looking deeper at the source code, this tool is a wrapper around a wrapper around a wrapper.... Don't get me wrong, it probably works, but it's currently using a rollup configuration that was created in 2018, the package itself has not seen any updates in 17 months and has 106 open issues. Also the owner says himself that he's not able to work that much on it anymore and suggest to use TSDX which in return hasn't been updated in several months, many open issues and extensive customization is recommended with patch-package which already in itself is a red-flag :(

create-react-library - CLI for creating reusable, modern React libraries using Rollup and create-react-app.

Using create-react-library to scaffold a React component library.

Here is great documentation for you to follow if you are interested in understanding the core concepts.

Can someone remind me why virtual DOM was/is desirable in the first place and why updating the DOM directly is desirable now?

If I understand correctly react elements are created in memory, and only upon "render" it is turned into the actual DOM. Supposedly manipulating the actual DOM is "heavy" hence delay/pruning the virtual DOM tree first then rendering would be beneficial? Then why is it working with DOM directly is desirable? And am I right to assume that "without virtual DOM" means work with DOM directly? Someone in the comment mention that Svelte is without vDOM already. Is there some design document that I can refer to, like the reconciliation engine used in react https://github.com/acdlite/react-fiber-architecture

Over the years, new view libraries that are even more performant than React have emerged. React may not be the fastest library out there, but in terms of the ecosystem, overall usage experience and benefits, it is still one of the greatest. Facebook is also channeling efforts into making React even faster with a rewrite of the underlying reconciliation algorithm. The concepts that React introduced has taught us how to write better code, more maintainable web apps and made us better engineers. We like that.

The concept is a bit complex, but if you're interested in finding out how we might see React in a few years, you can read this documentation from the React page: https://github.com/acdlite/react-fiber-architecture

Fiber is the new reconciliation engine in React 16. Its main goal is to enable incremental rendering of the virtual DOM. This is a complicated concept, basically, this new algorithm is a reimplementation of older versions of the React reconciler, has some improvements on prioritizing the order of how things are rendered, breaks the limits of the call stack, and lets it pause or start rendering work wherever required.

The result was "Jikji" library (why Jikji? it will need another blog:)) ). It uses React Fiber to get the component hierarchy and reorganized, split, and layout the components before rendering and making a print-ready web view that can easily be printed or converted to PDF or images.

The mechanism to diff one tree with another to determine which parts need to be changed and then update the original DOM with it is called Reconciliation. You can learn about Reconciliation here. ReactJS uses a new reconciliation engine called Fiber since version 16.0. You can read more about the React Fiber Architecture here.
