flareact VS react-loadable

there is https://github.com/flareact/flareact in development by a shopify engineer, worth checking out... seems like a good architecture for deeper integration with workers runtime

React Loadable: This library makes it easy to split your React code into smaller, lazy-loaded chunks that can be loaded on demand. This can significantly improve the initial loading time of your application, especially for large and complex apps. https://github.com/jamiebuilds/react-loadable

I have a very simple React component that uses react-loadable to dynamically import another component. The code looks something akin to the following:

react-loadable - A higher order component for loading components with promises

It's very important that you are choosing an active project instead of a dead/unmaintained project. An active project improves over time through community feedback. An unmaintained project does not move forward, fix functional bugs or patch security issues. Sometimes, a very popular package can be abandoned and go into a "frozen" state with many open issues and pull requests. It might have been a great solution in the past, but this is a sign that we have to move on. An example is react-loadable. It was a great solution for a very long time for code-splitting in React. I totally loved it. But it's stale now with many issues and PRs since 2018 (this post is written at the end of 2021). Now, if I need to split code in React, I use loadable-components, which is in active development, becoming more popular, patches bugs reported by the community, and most importantly, solves my problems. My personal advice: choose a package that's active in the last 3-6 months, with issues that are being resolved and PRs that are being merged.
