ng-di-analyzer

🧠 Rust-powered static analysis tool to detect NullInjectorError issues in Angular apps at compile-time.

What is ng-di-analyzer?

ng-di-analyzer is a blazing-fast CLI tool written in Rust that statically analyzes Angular projects to construct a full Dependency Injection (DI) tree and identify all possible paths that could lead to runtime NullInjectorError's.

Angular's DI system is powerful—but also brittle. In large applications, it’s easy to misconfigure providers or forget to add them in the right context. The result? A frustrating and often hard-to-reproduce NullInjectorError at runtime.

This tool shifts that pain to compile time.

Why use it?

• ✅ Catch NullInjectorErrors before they happen.
• ⚡ Rust-powered speed: Analyze large Angular codebases in seconds.
• 🧩 Understand your DI graph like never before.
• 🔍 Output all potential injection paths leading to errors.
