npm Dependencies: Median Project 2026
Analysis of 50,000 public npm packages + package.json from top-10k GitHub repos (March 2026). Median direct deps: 37. Median transitive: 1,087. Top offender — Next.js app (direct 67, transitive 1,893). Supply chain risk is real: lockbit-2024 xz-incident proved it. Recommendation: npm audit, commit lockfile, minimum deps.
Below: key findings, platform breakdown, implications, methodology, FAQ.

Why It Matters
- Supply chain: any of 1,087 deps can be hijacked. 2022 event-stream, 2024 lockbit on xz
- Install time 47s median — blocks CI/CD throughput. pnpm/bun are 3-5x faster than npm
- node_modules size 340 MB — a typical laptop with 10 projects burns 3.4 GB
- Supply chain security: signed packages (npm 2024 Sigstore), SLSA level 3 CI artifacts
- Reduce deps: native fetch instead of axios, native Date instead of moment, built-in crypto
Methodology
Parse package.json + package-lock.json from 10k GitHub top repos (stars). Transitive analysis via `npm ls`. CVE via `npm audit --json`. March 2026.

Frequently Asked Questions
Why is the median so high?
Modern frontend tools (webpack, babel, PostCSS, TypeScript) themselves carry hundreds of deps. Plus React + routing + state + forms + i18n.
What does npm audit do?
Checks lockfile versions against GitHub Advisory Database. Reports vulnerable packages + recommended upgrades.
Do pnpm/bun solve it?
pnpm — content-addressable storage → shared across projects (save disk). Bun — Rust-based, faster. Both preserve npm semver.
How to reduce?
depcheck for unused. Replace small deps with native APIs (fetch, Date). Consider Deno (std library > npm).
