Is lodash.isequal still maintained?

No — lodash.isequal stopped being maintained around January 2017. node:util.isDeepStrictEqual covers this in the language or runtime now, so the right move is to delete the dependency rather than replace it.

What replaced lodash.isequal?

node:util.isDeepStrictEqual covers this in the language or runtime now, so the right move is to delete the dependency rather than replace it. There is no package to install; the dependency comes out and platform code goes in.

How to migrate from lodash.isequal to node:util.isDeepStrictEqual

isEqual(a, b) becomes require('node:util').isDeepStrictEqual(a, b) on the server. For browser bundles, dequal or fast-deep-equal are the usual small stand-ins.

Why lodash.isequal is on this list

lodash.isequal was last published in January 2017 and now carries a deprecation notice from the lodash maintainers reading "This package is deprecated. Use require('node:util').isDeepStrictEqual instead." That built-in has shipped with Node since version 9. The two are close but not identical: the Node version compares types and prototypes strictly.

The succession is settled: primary sources agree and the ecosystem has already moved.

lodash.isequal alternatives

Beyond the primary recommendation, these are credible for lodash.isequal's use case:

• lodash — view on npm
• dequal — view on npm
• fast-deep-equal — view on npm

Check your own project for lodash.isequal

npx dead-deps --all --min-state unmaintained

Run that in the directory holding your lockfile. If lodash.isequal 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.
