Node.js vs Bun vs Deno: npm package compatibility

Compare how tested npm packages load in Node.js, Bun and Deno. Each result names an exact package version, the tested runtimes and a report you can inspect or reproduce.

Node.js support does not establish Bun or Deno npm compatibility. Compare ESM import, CommonJS require and explicit subpaths using the same installed dependencies. A runtime may pass its observed checks while overall coverage remains limited.

These are loading tests on Linux amd64 / glibc, with install scripts and execution networking disabled. Passing does not prove functional correctness. Versions listed here are tested versions, not necessarily the latest releases. Reports prefer the current environment and fall back to eligible earlier observations.
