dead-deps — what happened to your dependencies

Is bluebird still maintained?

No — bluebird stopped being maintained around November 2019. Promise (native) covers this in the language or runtime now, so the right move is to delete the dependency rather than replace it.

What replaced bluebird?

Promise (native) 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 bluebird to Promise (native)

Delete the require('bluebird') and rely on the global Promise; for the concurrency helpers Bluebird provided, Promise.map maps onto p-map and Promise.promisify onto util.promisify.

Why bluebird is on this list

Bluebird's README now tells readers to "use native promises instead if at all possible", noting that native promises have been stable and fast for about a decade and that most of Bluebird's useful features were absorbed into the language. The last release was 3.7.2 in November 2019; the package is not formally deprecated on npm and still works. The maintainer suggests keeping Bluebird only for very old browsers, end-of-life Node.js, or temporarily for its warnings and monitoring.

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

bluebird alternatives

Beyond the primary recommendation, these are credible for bluebird's use case:

Check your own project for bluebird

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

Run that in the directory holding your lockfile. If bluebird 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.
