Advanced Effect Di Environment

Type-safe dependency modeling uses Effect-style Context and Layer patterns to validate environment composition at compile time, eliminating runtime errors. Define typed environments for services, then compose layers immutably to catch dependency issues before execution.

Compile-time dependency injection validates service relationships and environment structure during type checking, preventing broken configurations immediately. Runtime injection discovers dependencies at execution time, catching errors only after deployment.

Effect-style composition chains Service and Layer definitions immutably, allowing you to refactor entire dependency graphs incrementally while type safety prevents breaking changes. Each layer explicitly declares its dependencies, creating a verifiable graph.

Yes. Compile-time environment modeling aligns Context, Layer, and Service definitions with coding standards and templates before code execution, enabling design-time validation of architectural constraints.

Environment composition validation detects misconfigurations—missing services, circular dependencies, type mismatches—during compilation. This prevents silent failures and ensures your entire dependency graph is sound before runtime.
