Entrance Decorator

A minimal solution of dependency injection for projects that scale.

Why

🙂

Installation

yarn add entrance-decorator

Usage

Define entrances

import {entrance} from 'entrance-decorator';
export class Entrances {
  constructor(private url: string) {}
  @entrance
  get uiService() {
    return new UIService(this.errorService);
  }
  @entrance
  get errorService() {
    return new ErrorService({
      baseURL: this.url,
    });
  }
}

Extend/override entrances

import {entrance} from 'entrance-decorator';
export class MobileEntrances extends Entrances {
  // Extend entrance
  @entrance
  get mobileService() {
    return new MobileService(this.errorService);
  }
  // Override entrance
  @entrance
  get uiService() {
    return new MobileUIService(this.errorService);
  }
}

Use entrances

const entrances = new Entrances('https://makeflow.com');

You may use the entrances object in whatever way you want. For example, we use Context in React (in a decorator manner) and use something like entrances.launchServer() in server-side applications.

What it does

Cache and circular dependency check, nothing else.
