Could you build this?
No Translating the dynamic, untyped, lazily evaluated Nix expression language into the TypeScript AST requires deep compiler and type system expertise far beyond standard LLM synthesis.
What it would actually take: A developer needs a Nix parser (like rnix or tree-sitter-nix) and deep knowledge of both Nix semantics and TypeScript compiler internals. The hard part is mapping lazy evaluation, attribute set merging, and recursive scopes into TypeScript's structural type system while handling Nix built-ins and type inference. This requires an experienced compiler and programming language engineer.
