Feature-Sliced Design (FSD) is an architectural methodology for frontend projects that structures code into layers and slices. It provides a strict public API for each slice to manage dependencies and isolate business logic effectively.

To migrate to Feature-Sliced Design, you load the 04-migration reference to follow structured steps. It guides you through restructuring existing folders into FSD layers while resolving cross-imports and maintaining application stability.

Feature-Sliced Design works across multiple frontend frameworks by providing framework-agnostic architectural rules. The 05-framework-integrations reference details how to apply FSD patterns within specific platform environments and toolchains.

You resolve cross-imports in Feature-Sliced Design by enforcing the public API rule defined in the core reference. Each slice must expose functionality only through its public interface, preventing lower layers from importing higher-level modules.

You find practical guides and the core philosophy of FSD by accessing the 06-practical-guides and 07-philosophy references. These sections provide context-aware routing to explain the methodology's reasoning and real-world application patterns.
