Wire is a compile-time dependency injection framework for Go that generates code to wire application components together. It analyzes function signatures at compile time to build an explicit initialization graph, removing the need for runtime reflection or manual wiring code.
The framework operates as a Go code generator and static analysis tool, transforming annotated source code into generated wire files that compile alongside the original project. It connects dependencies by matching function parameters and return types, producing a directed acyclic graph of component dependencies that is fully resolved before runtime execution.
Wire generates dependency injection code by analyzing function signatures and producing wire-ready Go source files through source-to-source transformation. The generator composes components into a single initialization function, ensuring all dependencies are satisfied without runtime inspection.
