Could you build this?
No Building a functional package manager in Rust requires writing a complex SAT-solver/PubGrub dependency resolver, handling npm registry semantics, lifecycle scripts, linking/hoisting algorithms, and high-concurrency tarball decompression.
What it would actually take: A real npm-compatible package manager requires a high-performance HTTP client (reqwest), a PubGrub or CDCL-based dependency resolution engine, lockfile serialization, hardlinking/symlinking trees (like pnpm/uv), and execution sandboxes for lifecycle scripts. The hard part is handling the messy edge cases of the npm ecosystem: peer dependency resolution, cyclical dependencies, version ranges, and cross-platform file locking during concurrent installations.
