Injex

Simple, Decorated, Pluggable dependency-injection framework for TypeScript applications

Injex makes software architecture more easy & fun by creating a dependency tree between your application modules with a minimal API.

Installation

Start by installing the core package. This package includes most of the functionality you're going to use when working with the Injex framework.

npm install --save @injex/core

After the core is installed and based on your project, you need to install a runtime container. The runtime container enables modules definition and registration across your application.

You can currently choose between the Node, Webpack or Vite runtimes for the server or the client.

Node Runtime

Create a dependency-injection container inside a Node.JS application.

npm install --save @injex/node

Webpack Runtime

Create a dependency-injection container inside a Webpack client-side application.

npm install --save @injex/webpack

Vite Runtime

Create a dependency-injection container inside a Vite client-side application.

npm install --save @injex/vite

Getting Started

Basic Usage

Create an Injex Node runtime container.

import { Injex } from "@injex/node";

Injex.create({
    rootDirs: [
        "./src"
    ]
}).bootstrap()

Injex will scan all the files and folders recursively and look for Injex modules.

Module definition example:

// src/services/mailService.ts
import { define, singleton, inject } from "@injex/core";

@define()
@singleton()
export class MailService {
    @inject() private mailProvider: IMailProvider;

    public sendMail(mail: Mail) {
        this.mailProvider.send(mail);
    }
}

Since Injex automatically scans all the files and folders inside the rootDirs, this is all you need to do to create an injectable module.
