Compdi

Zero-overhead, compile-time dependency injection for TypeScript.

Compdi rewrites typed macro calls during your build. The generated code directly constructs and wires your dependencies, so your application ships without a runtime container, decorator metadata, or string tokens.

Why Compdi?

• Compile-time erasure — macro calls become ordinary JavaScript before runtime.
• Type-safe dependencies — constructor and factory parameters drive TypeScript inference.
• No metadata runtime — no reflect-metadata, parameter decorators, or container lookup.
• Explicit lifecycles — singleton, transient, scoped, and application teardown APIs.
• Build-tool support — Vite, Rollup, Rolldown, Rspack, and esbuild.

Install

pnpm add compdi

npm install compdi

yarn add compdi

Continue with the quick start to wire your first dependency graph.
