From 0.16.8 to 0.16.9 : ReferenceError: require is not defined

Hi there,

I was using twind for quite some time on my project : https://github.com/Shuunen/what-now/

I’m using twind/shim for months without any issues via this 2 lines of code :

import { setup } from 'twind/shim'`
setup({ mode: 'silent' })

My project is in TypeScript, I build a iife package for web with tsup/esbuild.

Until recently, everything was working well, but the lastest upgrade from 0.16.8 to 0.16.9 has bring this error ReferenceError: require is not defined on my website.

If I rollback twind to 0.16.8 then build & deploy again : it works as expected, no more error

I looked at https://github.com/tw-in-js/twind/compare/v0.16.8...v0.16.9 , but it’s hard to see which commit introduced this, maybe the chore: deps upgrade a501131 ?

If we compare the 2 builds : 0.16.8 on the left & 0.16.9 on the right :

We can see that require("url") is appearing with the update, there are 2 other occurences of this same require on the build.
