# Angular 2+/Ionic 2+ Drupal 7 Services
#### Typescript angular module for [Drupal Services 3.x](https://www.drupal.org/project/services)

[![npm version](https://badge.fury.io/js/ngx-drupal7-services.svg)](https://badge.fury.io/js/ngx-drupal7-services)  

Angular Drupal 7 Services is a REST client for Angular 2+, which allows you to use predefined functions when communication with Drupal's api endpoints.  
Unlike the other project focusing on the same topic, Angular Drupal 7 Services is precisely organized around the [Drupal Services 3.x](https://www.drupal.org/project/services) architecture and naming conventions.   
  
It optionally provides events next to the common used observable approach.

A full set of Drupal's resources is available, and all basic workflow's depending to authentication or helpers for CRUD operations are also provided as a set of extra modules.

Also supports Server Side Rendering "Angular Universal".

## DEMOS
Running the demo:
```bash
git clone https://github.com/wnabil/ngx-drupal7-services.git
cd ngx-drupal7-services
npm install
ng serve
```
Then navigate to `localhost:4200` via your browser.

## Get Started

**(1)** Get Angular Drupal 7 Services:
```bash
npm install --save ngx-drupal7-services
```

**(2)** import `ngx-drupal7-services` in your `app.module.ts` and `imports` array.
```javascript
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppComponent } from './app.component';

import { Drupal7ServicesModule, DrupalConstants, Settings } from 'ngx-drupal7-services';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    Drupal7ServicesModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
```

**(3)** Implement `'DrupalConstants.Settings'` to add the back-end configuration and add it to `AppModule' constructor.

```javascript
export class AppModule {
  constructor () {
    const drupalSettings: Settings = {
      apiEndPoint: 'api',
      apiHost: 'localhost',
      apiProtocol: 'http',
      language: 'und',
      requestTimeout: 5000,
      allowOffline: true // optional
    };
    DrupalConstants.Settings = drupalSettings;
    // OPTIONAL
    DrupalConstants.Instance.handleOffline = this.customHandle;
  }

  /**
   * OPTIONAL
   * custom http offline handler
   * you can add sweet alert message for example
   * Note that you always must return an Observable
   */
  customHandle() {
    alert("custom offline handler! you are offline");
    return Observable.of();
  }
}
```

**(4)** Import the required service into your component and use the methods inside it
```javascript 
import { UserService } from 'ngx-drupal7-services';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  constructor(private userService: UserService) { }

  login(username: string, password: string) {
    const user = {
      username: username,
      password: password
    };
    this.userService.login(user).subscribe(connection => {
      // re-direct to user pofile or show welcome message.
    });
  }
}
```

## Contribution, Ideas and pull requests are welcome, Please open an issue on Github or contact me on w.nabil@orangestudio.com if i didn't response in approx 2 days.

## Configuration
Basically all configurable options are wrapped in an angular constant.
You must implement your own application configuration for the DrupalConstants.Settings as shown above.
