Npmjs
Worth it
Confidence: Medium
If you write JavaScript, npm is effectively mandatory . it's the default package registry and free for public packages.
Comparison
Npmjs lands on Worth it, and Home page | Yarn lands on Depends.
If you write JavaScript, npm is effectively mandatory . it's the default package registry and free for public packages.
Worth adopting if you run a large JavaScript monorepo needing workspaces and deterministic installs; otherwise npm, which ships free with Node, is enough.
| Compare | Npmjs | Home page | Yarn |
|---|---|---|
| Verdict | Worth it | Depends |
| Best for | JavaScript/Node.js developers | JavaScript monorepos |
| Who it's not for | Non-JavaScript stacks . use PyPI, NuGet, or Maven instead | Solo devs and small projects . npm ships with Node |
| Privacy | High-risk: repeated supply-chain compromises, including a Sept 2025 worm affecting 19 popular packages; 19 CVEs tracked.⁷ | The Yarn 1.22.22 package was flagged with 2 vulnerabilities (highest severity 7.5) by a dependency scan; no security page found on the official site.14 |
| Support quality | Reddit users call the site abandoned | No support evidence in sources |
| Public sentiment | Review volume is tiny; G2 users find package management easy, while Reddit threads criticize site neglect, publishing friction, package quality, and security.² | No verbatim user reviews found; evidence is limited to the official site and one dependency scan.12 |
| Biggest gotcha | One compromised maintainer account can push malicious updates to hundreds of millions of weekly installs.15 | Guess: Classic (v1) vs Modern (Berry) version split confuses setup; verify which version tutorials target.12 |
