The fastest way to get started

Quick installation of Injex core and Node.JS/Webpack runtime.

Injex runtimes are consistent so that you wouldn't notice any change. Full Stack TypeScript development (server/client) at its best.

  • Unopinionated
  • Minimalist API
  • Use decorators to play
  • Flexible with plugins
  • Small size footprint

Checkout the examples page for full examples and use cases.

Install using npm or yarn

npm install --save @injex/core @injex/node

Import and create Injex container.

import { Injex } from "@injex/node";
Injex.create({
rootDirs: [
__dirname
]
}).bootstrap();

Create and define modules using decorators

import { define, singleton, inject, injectAlias, AliasMap } from "@injex/core";
@define()
@singleton()
export class MailService {
@inject() private env: IEnvironment;
@injectAlias("IMailProvider", "Type") private mailProviders: AliasMap<MailProviderType, IMailProvider>;
public send(message: Mail) {
const mailProvider = this.mailProviders[this.env.mailProvider];
mailProvider.send(message);
}
}
