# Improved evaluation times with pre-resolved Nix store paths

**[Determinate Systems](https://daily.dev/sources/determinate-systems)** · 6 min read · 0 upvotes · 0 comments

## Summary

FlakeHub now offers pre-resolved Nix store paths, eliminating the evaluation tax when deploying Nix-based configurations. Instead of running expensive Nix evaluation to determine a derivation's store path, the `fh` CLI fetches already-calculated paths directly from FlakeHub's database. This enables two key workflows: `fh resolve` retrieves store paths without Nix installed, and `fh apply` applies NixOS, Home Manager, or nix-darwin configurations directly from a flake reference — all without evaluation overhead. This is especially valuable for resource-constrained devices like Raspberry Pis or IoT sensors. Store paths are generated during flake publishing via the `flakehub-push` GitHub Action with a single configuration option, and access is controlled by flake visibility settings.
