# Ionic Native

Ionic Native is a curated set of wrappers for Cordova plugins that make adding any native functionality you need to your [Ionic](https://ionicframework.com/) mobile app easy.

Ionic Native wraps plugin callbacks in a Promise or Observable, providing a common interface for all plugins and making it easy to use plugins with Angular change detection.

## Installation

Run following command to install Ionic Native in your project.
```bash
npm install @ionic-native/core --save
```

You also need to install the Ionic Native package for each plugin you want to add. Please see the [Ionic Native documentation](https://ionicframework.com/docs/native/) for complete instructions on how to add and use the plugins.

## Documentation

For the full Ionic Native documentation, please visit [https://ionicframework.com/docs/native/](https://ionicframework.com/docs/native/).

### Basic Usage

To use a plugin, import and add the plugin provider to your `@NgModule`, and then inject it where you wish to use it.

```typescript
// app.module.ts
import { Camera } from '@ionic-native/camera';

...

@NgModule({
  ...

  providers: [
    ...
    Camera
    ...
  ]
  ...
})
export class AppModule { }
```

```typescript
import { Geolocation } from '@ionic-native/geolocation';
import { Platform } from 'ionic-angular';

import { NgZone } from '@angular/core';

@Component({ ... })
export class MyComponent {

  constructor(private geolocation: Geolocation, private platform: Platform) {

    platform.ready().then(() => {

      // get position
      geolocation.getCurrentPosition().then(pos => {
        console.log(`lat: ${pos.coords.latitude}, lon: ${pos.coords.longitude}`)
      });


      // watch position
      const watch = geolocation.watchPosition().subscribe(pos => {
        console.log(`lat: ${pos.coords.latitude}, lon: ${pos.coords.longitude}`)
        this.position = pos;
      });

      // to stop watching
      watch.unsubscribe();
    });
    
  }
  
}
```

### Mocking and Browser Development

Ionic Native 3.x makes it possible to mock plugins and develop nearly the entirety of your app in the browser or in `ionic serve`.

To do this, you need to provide a mock implementation of the plugins you wish to use. Here's an example of mocking the `Camera` plugin to return a stock image while in development:

First import the `Camera` class in your `src/app/app.module.ts` file:

```typescript
import { Camera } from '@ionic-native/camera';
```

Then create a new class that extends the `Camera` class with a mock implementation:

```typescript
class CameraMock extends Camera {
  getPicture(options) {
    return new Promise((resolve, reject) => {
      resolve("BASE_64_ENCODED_DATA_GOES_HERE");
    })
  }
}
```

Finally, override the previous `Camera` class in your `providers` for this module:

```typescript
providers: [
  { provide: Camera, useClass: CameraMock }
]
```

Here's the full example:

```typescript
import { NgModule, ErrorHandler } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { IonicApp, IonicModule, IonicErrorHandler } from 'ionic-angular';
import { MyApp } from './app.component';
import { HomePage } from '../pages/home/home';

import { Camera } from '@ionic-native/camera';

class CameraMock extends Camera {
  getPicture(options) {
    return new Promise((resolve, reject) => {
      resolve("BASE_64_ENCODED_DATA_GOES_HERE");
    })
  }
}

@NgModule({
  declarations: [
    MyApp,
    HomePage
  ],
  imports: [
    BrowserModule,
    IonicModule.forRoot(MyApp)
  ],
  bootstrap: [IonicApp],
  entryComponents: [
    MyApp,
    HomePage
  ],
  providers: [
    {provide: ErrorHandler, useClass: IonicErrorHandler},
    { provide: Camera, useClass: CameraMock }
  ]
})
export class AppModule {}
```


### Runtime Diagnostics

Spent way too long diagnosing an issue only to realize a plugin wasn't firing or installed? Ionic Native lets you know what the issue is and how you can resolve it.
