# 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@beta --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.

**NOTE: to use Ionic Native v5, you must use the `@beta` tag when installing any NPM package.**

## Documentation

For the full Ionic Native documentation, please visit [https://ionicframework.com/docs/native/](https://ionicframework.com/docs/native/).

### Basic Usage

#### Ionic/Angular apps
To use a plugin, import and add the plugin provider to your `@NgModule`, and then inject it where you wish to use it. 
Make sure to import the injectable class from the `/ngx` directory as shown in the following examples:

```typescript
// app.module.ts
import { Camera } from '@ionic-native/camera/ngx';

...

@NgModule({
  ...

  providers: [
    ...
    Camera
    ...
  ]
  ...
})
export class AppModule { }
```

```typescript
import { Geolocation } from '@ionic-native/geolocation/ngx';
import { Platform } from 'ionic-angular';

@Component({ ... })
export class MyComponent {

  constructor(private geolocation: Geolocation, private platform: Platform) {

    this.platform.ready().then(() => {

      // get position
      this.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}`)
      });

      // to stop watching
      watch.unsubscribe();
    });

  }

}
```

#### ES2015+/TypeScript
These modules can work in any ES2015+/TypeScript app (including Angular/Ionic apps). To use any plugin, import the class from the appropriate package, and use it's static methods.
```js
import { Camera } from '@ionic-native/camera';

document.addEventListener('deviceready', () => {
  Camera.getPicture()
    .then((data) => console.log('Took a picture!',  data))
    .catch((e) => console.log('Error occurred while taking a picture', e));
});
```

#### AngularJS
Ionic Native generates an AngularJS module in runtime and prepares a service for each plugin. To use the plugins in your AngularJS app:
1. Download the latest bundle from the [Github releases](https://github.com/ionic-team/ionic-native/releases) page.
2. Include it in `index.html` before your app's code.
3. Inject `ionic.native` module in your app.
4. Inject any plugin you would like to use with a `$cordova` prefix.

```js
angular.module('myApp', ['ionic.native'])
  .controller('MyPageController', function($cordovaCamera) {
    $cordovaCamera.getPicture()
      .then(
        function(data) {
          console.log('Took a picture!', data);
        },
        function(err) {
          console.log('Error occurred while taking a picture', err);
        }
      );
  });
```

#### Vanilla JS
To use Ionic Native in any other setup:
1. Download the latest bundle from the [Github releases](https://github.com/ionic-team/ionic-native/releases) page.
2. Include it in `index.html` before your app's code.
3. Access any plugin using the global `IonicNative` variable.

```js
document.addEventListener('deviceready', function() {
  IonicNative.Camera.getPicture()
    .then(
      function(data) {
        console.log('Took a picture!', data);
      },
      function(err) {
        console.log('Error occurred while taking a picture', err);
      }
    );
});
```


### Mocking and Browser Development (Ionic/Angular apps only)

Ionic Native 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/ngx';
```

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 { ErrorHandler, NgModule } 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/ngx';

import { HomePage } from '../pages/home/home';
import { MyApp } from './app.component';

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.
