Describe your issue

The Tailwindcss intellisense is not working in my project. I suspect the problem is the tailwind config file, currently my config file is written in typescript whereas the extension supports config file in javascript. In case I change the config file to javascript the intellisense starts working.

Hey @Amrender-Singh, this is most likely because you're using an old version of the extension. If you upgrade to the latest version you should be good to go 👍

[Amrender-Singh]

I can confirm it is working fine with latest version. Thanks
