Typed Inject

Typed Inject is a robust, 100% type-safe dependency injection framework specifically designed for TypeScript applications. It allows developers to inject classes, interfaces, or primitive values, leveraging TypeScript's type system to ensure that if a project compiles, its dependencies are correctly resolved at runtime with their declared types. The current stable version is 5.0.0, released in late 2024. Major versions typically roll out with significant changes like Node.js version updates or module system migrations, as seen with the v4.0.0 (ESM migration) and v5.0.0 (Node 16 drop) releases. Its primary differentiator is its strong type-safety, which virtually eliminates runtime dependency resolution errors by shifting validation to compile time. It handles various injection patterns, including class, value, and factory providers, and supports concepts like child injectors and lifecycle control.
