About

InversifyJS is a lightweight inversion of control (IoC) container for TypeScript and JavaScript apps. An IoC container uses a class constructor to identify and inject its dependencies. InversifyJS has a friendly API and encourages the usage of the best OOP and IoC practices.

Motivation

JavaScript now supports object oriented (OO) programming with class based inheritance. These features are great but the truth is that they are also dangerous.

We need a good OO design (SOLID, Composite Reuse, etc.) to protect ourselves from these threats. The problem is that OO design is difficult and that is exactly why we created InversifyJS.

InversifyJS is a tool that helps JavaScript developers write code with good OO design.

Philosophy

InversifyJS has been developed with 4 main goals:

1. Allow JavaScript developers to write code that adheres to the SOLID principles.

2. Facilitate and encourage the adherence to the best OOP and IoC practices.

3. Add as little runtime overhead as possible.

4. Provide a state of the art development experience.

Testimonies

Nate Kohari - Author of Ninject

"Nice work! I've taken a couple shots at creating DI frameworks for JavaScript and TypeScript, but the lack of RTTI really hinders things. The ES7 metadata gets us part of the way there (as you've discovered). Keep up the great work!"

Michel Weststrate - Author of MobX

Dependency injection like InversifyJS works nicely
