# 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) {
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: ${pos.coords.longitude}`)
this.position = pos;
});
// to stop watching
watch.unsubscribe();
});
}
}
```
#### ES2015+/TypeScript
These modules can work in any ES2015+/TypeScript app (including Angular/Ionic apps). To use any plugin, import the class from the appropriate package, and use it's static methods.
```js
import { Camera } from '@ionic-native/camera';
document.addEventListener('deviceready', () => {
Camera.getPicture()
.then((data) => console.log('Took a picture!', data))
.catch((e) => console.log('Error occurred while taking a picture', e));
});
```
#### AngularJS
Ionic Native generates an AngularJS module in runtime and prepares a service for each plugin. To use the plugins in your AngularJS app:
1. Download the latest bundle from the [Github releases](https://github.com/ionic-team/ionic-native/releases) page.
2. Include it in `index.html` before your app's code.
3. Inject `ionic.native` module in your app.
4. Inject any plugin you would like to use with a `$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 { 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/ngx';
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.
## Plugin Missing?
Let us know or submit a PR! Take a look at [the Developer Guide](https://github.com/ionic-team/ionic-native/blob/master/DEVELOPER.md) for more on how to contribute. :heart:
