Tailwindcss 4+ -> hase -> amqplib "BadEngine" warning in AWS Amplify/React/Vite project

[jacheson]

I'm attempting to clear the warning:
2025-03-21T15:03:26.801Z [WARNING]: WARN EBADENGINE Unsupported engine {
-npm WARN EBADENGINE package: '[email protected]',
-npm WARN EBADENGINE required: { node: '>=0.8 <=9' },
...

But when I install the latest version of tailwindcss from npm, it adds [email protected] as a dependency, which adds [email protected] as a dependency.
Are these packages actually dependencies, or can they be safely removed?

In the meantime, I'm reverting to an earlier tailwindcss version (3.4.1) to try to clear this warning.

Are you sure it is a deep Tailwind dependency? I tried locally and this is what I get:

$ npm install tailwindcss

added 1 package in 536ms
$ npm ls tailwindcss
test@ /home/justin/projects/test
└── [email protected]
$ npm ls amqplib
test@ /home/justin/projects/test
└── (empty)
$ npm ls hase
test@ /home/justin/projects/test
└── (empty)

Perhaps do npm ls amqplib to see what it is a dependency of.

Hi wongjn,

I've removed it now, but the scaffold looked like this:
[email protected]
[email protected]
[email protected]

One possible difference between your scenario and mine is that I had installed the tailwindcss/vite plugin in vite.config.ts. (now removed, but that may give me problems later.)

Looks like removing @tailwindcss/vite is causing errors.

Hi. You may have installed tailwind rather than tailwindcss.
