Introduction to Flakes

The flakes experimental feature is a major development for Nix, it introduces a policy for managing dependencies between Nix expressions, it improves reproducibility, composability and usability in the Nix ecosystem. Although it's still an experimental feature, flakes have been widely used by the Nix community.¹

Flakes is one of the most significant changes the nix project has ever seen.²

A Word of Caution about Flakes

The benefits of Flakes are evident, and the entire NixOS community has embraced it wholeheartedly. Currently, more than half of the users utilize Flakes³, providing assurance that Flakes will not be deprecated.

⚠️ However, it's important to note that Flakes is still an experimental feature. Some issues persist, and there is a possibility of introducing breaking changes during the stabilization process. The extent of these breaking changes remains uncertain.

Overall, I strongly recommend everyone to use Flakes, especially since this book revolves around NixOS and Flakes. However, it's crucial to be prepared for potential problems that may arise due to forthcoming breaking changes.
