Could not find a declaration file for module 'react-jss/lib/jss'.

EDIT: I’m using typescript.

Hello, even if I already googled it, I’m not able to solve it.

Could not find a declaration file for module 'react-jss/lib/jss'.

Try `npm install @types/react-jss` if it exists or add a new declaration (.d.ts) 
file containing `declare module 'react-jss';`

I know is potentially an issue with JSS and not MUI, but has someone solved this?

Thanks.

Is it safe to close this? Seems like not a MUI issue…

I always considered importing from lib or dist or basically anything other than top level files to be bad practice. They do help tree shaking but if the publisher considers them private you have no guarantee that your package won’t break on the next patch.

Imports from react-jss/lib/* are currently scattered throughout the repo. Most of them can be transformed to imports from top level but the withStyles implementation relies on some internals.

Maybe we should open an issue over at react-jss and ask if they consider those imports save across minor version bumps and then work on proper ts definitions over at DefinitelyTyped.

For now you have to @ts-ignore or require those imports until typings are provided for that package.
