Angular Dependency Injection Kit

This library allows Angular developers to inject Components, Services and Modules to the main angular app via decorators. The library provides a number of decorators and corresponding global arrays to allow for a cleaner injection in the main Angualr App Module.

|Decorator |Global Array |Description | |-----------------|---------------------|------------------------------------------------------------------| |DIDeclare |declarations |Used to inject components into the App Module as declarations | |DIEntry |entries |Used to inject components into the App Module as entry components | |DIProvide |providers |Used to inject services into the App Module as providers | |DIRoute |routes |Used to inject components into the App Module as routes | |DIImport |importers |Used to inject modules into the App Module as imports | |DIExport |exporters |Used to inject components into the App Module as exports |

NOTE The user defined components, services and modules using these decorators must be imported into the Angular App Module. This will allow the decorators to push the user defined entities to their respective global arrays. Therefore, it is recommended to use an indexer and import as technique.

Installation

Do the following steps to install ng-di-kit:

npm install ng-di-kit

Usage

login.component.ts

import { DIDeclare } from "ng-di-kit";
import { Component, OnInit } from '@angular/core';

@DIDeclare()
@Component({
  selector: 'login-component',
  templateUrl: './login.component.html'
})
export class LoginComponent implements OnInit {
    ngOnInit() {

    }
}

login.service.ts

import { DIProvide } from 'ng-di-kit';
import { Injectable } from '@angular/core';

@DIProvide()
@Injectable()
export class LoginService  {

}

users.component.ts

import { DIRoute } from "ng-di-kit";
import { Component, OnInit } from '@angular/core';

@DIRoute(paths: ['/users'])
@Component({
  selector: 'users-component',
  templateUrl: './users.component.html'
})
export class UsersComponent implements OnInit {
    ngOnInit() {

    }
}

index.ts

export * from './login.component'
export * from './login.service'
export * from './users.component'

app.module.ts

import * as components from './index';
import { declarations, entries, providers, importers, routes } from 'ng-di-kit';
import { NgModule } from '@angular/core';
import { HttpClientModule } from '@angular/common';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';

// expose the components, modules and services to allow application of decorators
for(let key in components){
  components[key];
}

importers.push(BrowserModule);
importers.push(HttpClientModule);
importers.push(RouterModule.forRoot(routes));

@NgModule({
  imports: importers,
  providers: providers,
  declarations: declarations,
  entryComponents: entries,
  bootstrap: [ AppComponent ]
})
export class AppModule { }

Options

DIDeclare

|Name |Type |Default |Description | |--------------|---------------|---------|-------------------------------------------------------------------| |isEntry |boolean |false |Indicates if the declared component is also an entry component |

Example:

@DIDeclare({isEntry: true})
