snowpack dev is extremely slow with chakra-ui

[ADThomsen]

Hi everyone,

I have a react project in which I use chakra-ui. Since upgrading from snowpack version 3.2.2 we experience extremely slow performance using snowpack dev. The first build takes upwards of 15 minutes and each snowpack dev thereafter takes between 3 and 7 minutes before the dev server is ready.

I have created a minimal project to replicate the issue. It doesn't take as long as our real project, but it illustrates the issue well enough I think: https://github.com/ADThomsen/snowpack-slow

There are two branches:

• main
• snowpack-322

On each branch try

npm i
npm run start

Then try stopping the server and run npm run start again to see the slow load time after the cache has been built.

I'm creating this as a discussion because I'm unsure of where the issue lies and how to fix it - it might just be a configuration I don't know about.

Hint: I have observed on our main project that if I enter the following in our package.json

"snowpack": "3.2.2",
"rollup": "2.44"

it will work. I also noticed that the rollup version used by snowpack seems to have changed since version 3.2.2. I don't know if this information is of any use.

Does anyone have a suggestion as to what I should do?
