How to migrate from @material-ui/core to @mui/material
MUI ships codemods: npx @mui/codemod v5.0.0/preset-safe src handles most import paths and prop renames, then work through the remaining manual steps in the migration guide.
Why @material-ui/core is on this list
Material-UI was renamed MUI in 2021 and its packages moved from the @material-ui/* scope to @mui/*. The npm deprecation notice on @material-ui/core states that v4 has not received active development since September 2021 and links to the official v4 to v5 migration guide. The last v4 release was 4.12.4 in April 2022.
The succession is settled: primary sources agree and the ecosystem has already moved.
@material-ui/core alternatives
The dataset lists no second option: @mui/material is where the ecosystem went, and nothing else has meaningful adoption.
Check your own project for @material-ui/core
npx dead-deps --all --min-state unmaintainedRun that in the directory holding your lockfile. If @material-ui/core is anywhere in your tree — a direct dependency or buried under something else — it appears in the report with this verdict, this successor and the same evidence links, alongside anything else that has stopped moving. Nothing is uploaded; the scan reads your lockfile locally and queries public registry metadata.
Exit code 1 means something was flagged, which makes npx dead-deps --min-state deprecated usable as a CI gate. See how verdicts are produced.
