[core-docs] Use type-only imports for type-only references by JCQuintas · Pull Request #48386 · mui/material-ui (original) (raw)

Vite 8 uses Rolldown for production builds, which is stricter than Rollup about value-imports referencing names that have no runtime export. Several files import types like Theme, ThemeOptions, SxProps as value-imports from @mui/material/styles or @mui/system; Rolldown then fails with "X is not exported by ..." because those names exist only in declaration files.

Add the inline type modifier (or use import type) so the imports are erased at compile time and never reach the bundler.

mui/mui-public#1357 makes consistent-type-imports always-on in the shared base config, so the per-package override here would become redundant once material-ui bumps @mui/internal-code-infra.
