tyscript / js port

[Niko-La]

brilliant library.

possible to get a ts/js port as it would enable it to used on webapps and workers much easier than as a python lib

Hey thanks! I saw this library on X/Twitter. Does that work for you?

https://www.npmjs.com/package/langextract

Hi @aksg87 just wanted to confirm if that port is trustable. Since the author @kmbro has only published this one package on npm.

Hey @amanzrx4, I ported the package using a cursor AI agent, and I have it working in one of my projects already! It isn't a perfect 1 to 1 port, but it should be trustworthy in the "non-malicious" kind of way. Feel free to check out the source code here if you have more questions: https://github.com/kmbro/langextract-typescript Thanks!

@kmbro Thank you for providing the library. I attempted to integrate it, but I encountered a few fundamental issues that prevent us from using it effectively. The most significant problems are:

• It runs sequentially rather than concurrently, as seen in the original langextract.
• The examples included in the prompt do not align with the expected output schema.

I have submitted a pull request to address these issues. While it turned out to be quite extensive, it should now be more aligned with the original code. I would appreciate it if you could release a new version with these changes. Thank you!

Thank you for putting in the effort to port the library @kmbro! Will test it out for sure.

I was wondering, if there are any indications of an official port coming in a foreseeable future?

I haven't heard of anything or seen any updates. Sorry!
