Importing @tailwindcss/utilities in CSS file causes ENOBUFS error

[davidhao3300]

Describe the bug

Hello, me again.

The CSS transformer errors out with ENOBUFS with the following CSS file contents:

@import 'tailwindcss/utilities';

We use tailwindcss 1.9.6 if that helps, my suspicion is that it's just a large CSS file or something.

The full error:

  ● Test suite failed to run                                                                                                                         [110/1363]

    spawnSync node ENOBUFS

Corresponds to https://github.com/nvh95/jest-preview/blob/main/src/transform.ts#L356

I changed the erroring line to
const result = child_process.spawnSync('node', [tempFileName], {maxBuffer: 10 * 1024 * 1024});, which works. The maxBuffer default is 1MB or something, and not sure what you want the actual value to be.

Expected behavior

No error to occur

Hi @davidhao3300

Thanks for reporting this. Can you help to prepare a reproduction? It's hard for me to fix this without properly reproducing this. Thanks.

[davidhao3300]

I'm not a frontend expert, so this is my guess to a repro:

• Have tailwindcss@1.9.6 installed
• Have a single css file with @import 'tailwindcss/utilities'; as the contents
• include the CSS file and have it transformed by the jest-preview CSS transformer

hi, I am now getting this issue on my less local files, which are big
any chance to get a new version with the buffer fix?
