NPM@5 arrived. But is it as fast as Yarn?

Earlier this month, I posted about how yarn is much faster than npm, but today NPM itself posted on Medium about npm@5 and how fast it has become. I fell like I needed to add it to my former comparison, so here it goes.

New Lockfile

Shrinkwrap is (finally) deprecated. Now NPM creates/uses a package-lock.json (much better name :D) that is always created/updated much like the way Yarn does.

That means all installations, for all devs on a team, will look the same.

Speed improvements

NPM says all package metadata and cache have been reworked to make it from 20% to 100% faster. Cache is also self-healing to prevent corruption.

So let’s update our later comparison with npm@5 against Yarn.

Yarn is still faster. But NPM@5 is installing dependencies on half the time or even less than its prior version.

I’m not sure if it’s stable enough yet — considering the problems I had with npm shrinkwrap before — to justify a fallback to NPM. But it will certainly improve even more over time and maybe make Yarn obsolete.

I hope so.
