Postcss-nesting v12.0.4 is missing types field in package.json

[deluksic]

Looks like "postcss-nesting": 12.0.4 is missing "types": "./dist/index.d.ts", from its package.json causing typescript to not be able to find typings. When I re-add it, it works. Typescript 5.3.3.

Hi @deluksic,

That is not a bug.
We do not support types for commonjs.

see :

• packages provide wrong types under node16 module resolution #1031 (comment)
• If tsconfig.json is set to CommonJS mode, the declaration files cannot be read. #1303
• TypeScript error after upgrading postcss-preset-env from 9.3.0 to 9.4.0  #1295
• postcss-color-functional-notation doesn't expose TS types for CJS export #1217

What do I need to change in order for tsc to pass again? (bumped from 12.0.1)

Edit:
I have

"module": "ESNext",
"moduleResolution": "node",

but it should not be node?

node indicates that your context is commonjs.

Setting moduleResolution to nodeNext or node16 might help.

But keep in mind that this does have an overal effect and could surface other issues.
Setting a @ts-expect-error comment for postcss-nesting or providing empty placeholder types might be a more light weight solution.

OK, bundler option seems to be working, also with all other CI steps. I'm not using node for anything other than the dev server / tests, so this should be most appropriate. Thank you for the quick response.
