bun2nix

bun2nix is a fast Rust-based tool for converting lock-files generated by the JavaScript Bun (v1.2+) package manager to Nix expressions, which allows them to be consumed to build Bun packages reproducibly.

Advantages

Here are some of the advantages of using bun2nix over the alternatives:

• Much faster than other similar lang2nix tools for the JavaScript ecosystem - a full install will only take around 50ms for a medium project with 2k packages
• Build AOT-compiled binaries easily with Bun that fit the Nix model much better than NPM scripts
• Quality error messages because of the static types in Rust

Alternatives

Here are some alternatives to bun2nix in the JavaScript ecosystem which fulfill a similar purpose:

• node2nix
• yarn2nix
• js2nix
