JavaScript developers in 2025 have three major choices for package management: npm, Yarn, and pnpm. While they all do the job of installing packages, each has distinct performance characteristics, disk usage models, and developer experiences.
In this post, we’ll compare all three based on:
- ⚡ Speed & Performance
- 🧠 Dependency Management
- 📂 Disk Space Efficiency
- 📦 Workspaces & Monorepo Support
- 🔧 Developer Experience
- 🚀 Best Use Cases
⚡ 1. Speed & Performance
| Package Manager | Cold Install | Reinstall (Cache) | Benchmark Notes |
|---|---|---|---|
| npm 10+ | Moderate | Faster than before | Still improves |
| Yarn (Berry) | Fast | Very Fast | Uses Zero-Installs |
| pnpm | Blazing 🚀 | Fastest | Hard links & content-addressable store |
✅ Winner: pnpm
Its performance is unmatched due to hard links and an optimized caching mechanism.
🧠 2. Dependency Management Accuracy
- npm and Yarn use traditional node_modules layouts.
- pnpm uses a strict node_modules structure to avoid phantom dependencies.
This means that pnpm fails faster if your package.json is incorrect, preventing bugs from silent dependency leaks.
✅ Winner: pnpm
📂 3. Disk Space & Deduplication
- npm stores full copies per project.
- Yarn caches efficiently, especially with Plug’n’Play (PnP).
- pnpm links packages using symlinks, saving GBs of space across projects.
✅ Winner: pnpm
It’s ideal for developers juggling many repos or monorepos on the same machine.
📦 4. Workspaces & Monorepo Support
- npm supports Workspaces, but lacks deep tooling.
- Yarn Workspaces are mature and widely adopted.
- pnpm shines in monorepo tooling, offering built-in support, filtering, and scoped commands.
✅ Winner: pnpm, with Yarn as a close second.
🔧 5. Developer Experience & Ecosystem
| Feature | npm | Yarn | pnpm |
|---|---|---|---|
| CLI Simplicity | ✅ Easy | 🟡 Complex (Berry) | ✅ Familiar |
| Lockfile Clarity | ✅ JSON | 🟡 YAML | ✅ YAML |
| Plug’n’Play Support | ❌ | ✅ Yes | 🟡 Experimental |
| Community/Docs | ✅ Strong | ✅ Active | ✅ Growing Fast |
✅ Winner: Depends on the team
- npm is perfect for simplicity and default Node.js support.
- Yarn Berry is powerful but has a steeper learning curve.
- pnpm has a clean, fast CLI with modern features.
🚀 Final Verdict: Which One Should You Choose?
| Use Case | Recommendation |
|---|---|
| Beginners & Simple Projects | npm |
| Enterprise Monorepos | pnpm ✅ |
| Plug’n’Play (no node_modules) | Yarn Berry |
| Speed, Efficiency, Reliability | pnpm |
🏆 My Pick in 2025: pnpm
Fast, strict, and reliable — it’s built for modern workflows.

What are your sources? I believe some things are not true:
You can of corse correct me if I'm wrong
Good points — you’re mostly right!
Yarn Berry (v2+) does default to Plug’n’Play now, though many teams still switch back to nodeLinker: node-modules for tool compatibility. So “doesn’t use node_modules anymore” is true by default, but not universal.
And yeah, pnpm’s own benchmarks actually show Yarn PnP performing slightly faster in certain cold-install cases — mostly because it skips creating a node_modules tree. But in real-world usage (cached installs, CI/CD, or big monorepos), pnpm still tends to come out ahead thanks to its hard-linking and store reuse.
On disk efficiency, I agree — both Yarn PnP and pnpm are great now, since they both use a global content-addressable store. The main difference is pnpm achieves that while staying 100% Node-compatible, whereas Yarn’s PnP needs extra tooling support.
So yeah, Yarn PnP is technically amazing, but pnpm often wins in practicality
