No — q stopped being maintained around October 2017. 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 q?

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 q to Promise (native)

Q.defer() becomes new Promise((resolve, reject) => …), Q.all becomes Promise.all, and Q.nfcall(fn, …) becomes util.promisify(fn)(…).

Why q is on this list

Q was one of the promise libraries that shaped the JavaScript promise specification, and its author deprecated it on npm with a note saying users "can almost certainly migrate to the native JavaScript promise now". The last release was 1.5.1 in October 2017 and the repository is archived. Native promises have been available in every supported Node.js release for years.

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

q alternatives

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

• bluebird — also succeeded; see its page

Check your own project for q

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

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

Evidence

Every claim on this page traces to a primary source. Check them:

• npm deprecation notice from the author of Qnpmjs.com
