Infact is a lightweight, metadata-driven dependency injection container for TypeScript that prioritizes flexibility over convention. It provides instance factories and registries with support for singleton lifecycles, scoped instances, global sharing, circular dependencies, and class substitution, all without imposing a specific decorator pattern. Developers define class metadata through a `describeClass` callback, enabling integration with custom metadata sources like Reflect, manual registries, or code generation. The library is ideal for TypeScript projects needing fine-grained control over dependency resolution and lifecycle management.
