Hi @simon360

Review the pull request and requesting you to publish new package.

Thanks

Hi @sivaraj-v! I appreciate the PR, but this repository has been idle for quite some time. The packages are not widely used, and I would generally recommend alternative approaches for modern React development.

While I understand that's likely not the outcome you're looking for, I'm not able to take on any maintenance burden for this project, and given the current trend of supply chain-based attacks, I'm not comfortable handing the project over to another maintainer. As such, I'll be archiving this repository shortly.

If you still require react-from-markup, I'd suggest forking this repository and publishing it either on a private npm repository, or under a different public namespace.
