## Getting Started 🔧
24+
25+
Here's how to get started with react-native-audio-waveform in your React Native project:
26+
27+
### Installation
28+
29+
##### 1. Install the package
30+
31+
```sh
32+
npm install react-native-audio-waveform react-native-gesture-handler
33+
```
34+
35+
###### --- or ---
36+
37+
```sh
38+
yarn add react-native-audio-waveform react-native-gesture-handler
39+
```
40+
41+
##### 2. Install cocoapods in the ios project
42+
43+
```bash
44+
npx pod-install
45+
```
46+
47+
##### Know more about [react-native-gesture-handler](https://www.npmjs.com/package/react-native-gesture-handler)
48+
49+
##### 3. Add Permission in iOS
50+
51+
if you want to use recorder features in iOS side you have to add **NSMicrophoneUsageDescription** permission in info.plist and add description based on your use-case.
52+
53+
here is a sample for info.plist permission and description
54+
55+
```plist
56+
<key>NSMicrophoneUsageDescription</key>
57+
<string>Needed permission to record audio</string>
58+
```
59+
60+
### Usage
61+
62+
#### 1. Static waveform
63+
64+
When you want to show a waveform for pre-existing audio file you need to use `static` mode for the waveform. We have provided type safety for forward ref so that if you pass the `static` mode then you can only assign ref type of `IPlayWaveformRef` to the waveform.
65+
66+
Check below example for more information.
67+
68+
```tsx
69+
import { IPlayWaveformRef, Waveform } from 'react-native-audio-waveform';
70+
71+
const path = ''; // path to the audio file for which you want to show waveform
72+
const ref = useRef<IPlayWaveformRef>(null);
73+
<Waveform<'static'>
74+
mode="static"
75+
ref={ref}
76+
path={item}
77+
candleSpace={2}
78+
candleWidth={4}
79+
scrubColor="white"
80+
onPlayerStateChange={playerState => console.log(playerState)}
81+
onPanStateChange={isMoving => console.log(isMoving)}
82+
/>;
83+
```
84+
85+
#### 2. Live recording waveform
86+
87+
When you are want to record a audio and show waveform that recording at that time you need to create waveform with `live` mode. Same as `static` mode we have type safety for ref. You can only provide `IRecordWaveformRef` to `live` mode waveform.
88+
89+
Check below example for more information.
90+
91+
```tsx
92+
import { IRecordWaveformRef, Waveform } from 'react-native-audio-waveform';
93+
94+
const ref = useRef<IRecordWaveformRef>(null);
95+
<Waveform<'live'>
96+
mode="live"
97+
ref={ref}
98+
candleSpace={2}
99+
candleWidth={4}
100+
onRecorderStateChange={recorderState => console.log(recorderState)}
101+
/>;
102+
```
103+
104+
you can check full example at [Example](./example/src/App.tsx).

112+
| mode\* | - | both | 'live' or 'static' | Type of waveform. It can be either `static` for resources file or `live` if you want to record audio |
113+
| ref\* | - | both | IPlayWaveformRef or IRecordWaveformRef | Type of ref provided to waveform component. If waveform mode is `static`, ref type must be `IPlayWaveformRef` and if waveform mode is `live`, ref type must be `IRecordWaveformRef`.<br> Check [IPlayWaveformRef](#iplaywaveformref-methods) and [IRecordWaveformRef](#irecordwaveformref-methods) for more details about which methods these refs provides. |
114+
| path\* | - | static | string | Used for `static` type. It is resource path of audio source file. |
115+
| candleSpace | 2 | both | number | Space between two candlestick of waveform |
116+
| candleWidth | 5 | both | number | Width of single candlestick of waveform |
117+
| containerStyle | - | both | `StyleProp<ViewStyle>` | style of the container |
118+
| waveColor | #545454 | both | string | colour of candlestick of waveform |
119+
| scrubColor | #7b7b7b | static | string | colour of candlestick of waveform which has played |
120+
| onPlayerStateChange | - | static | ( playerState : PlayerState ) => void | callback function which returns player state whenever player state changes. |
121+
| onPanStateChange | - | static | ( panMoving : boolean ) => void | callback function which returns boolean indicating whether pan gesture is active or not. |
122+
| onRecorderStateChange | - | live | ( recorderState : RecorderState ) => void | callback function which returns the recorder state whenever the recorder state changes. Check RecorderState for more details |
123+
124+

startPlayer({
136+
finishMode?: FinishMode;

164+
```
165+
166+
It returns boolean indicating whether playback is resumed again.
167+
168+
#### IRecordWaveformRef methods
169+
170+
#### startRecord()
171+
172+
```ts
173+
startRecord({
174+
encoder: number;
175+
sampleRate: number;
176+
bitRate: number;
177+
fileNameFormat: string;

}): Promise<boolean>;
181+
```
182+
183+
Start a new audio recording with given parameters. It will return the if recording was started or not.
184+
185+
Check [UpdateFrequency](#updatefrequency) to know more.
186+
187+
> Note: Before starting the recording, User must have to allow **NSMicrophoneUsageDescription** for iOS. You can check the permissions by using **_checkHasAudioRecorderPermission_** from **_useAudioPermission_**. Check [useAudioPermission](#useaudiopermission-hook) to know more about various methods.
188+
189+
#### stopRecord()
190+
191+
```ts
192+
stopRecord(): Promise<string>
193+
```
194+
195+
It returns string representing the current recorded audio file path.
196+
197+
#### pauseRecord()
198+
199+
```ts
200+
pauseRecord(): Promise<boolean>
201+
```
202+
203+
It returns boolean indicating whether recording is paused.
204+
205+
#### resumeRecord()
206+
207+
```ts
208+
resumeRecord(): Promise<boolean>
209+
```
210+
211+

212+
213+
### useAudioPermission hook
214+
215+
By using this hook you can check and ask for permission from user for **NSMicrophoneUsageDescription** permission.
216+
217+
#### checkHasAudioRecorderPermission()
218+
219+
This method checks whether user has permission to use Microphone for recording new audio. It will return [PermissionStatus](#permissionstatus).
220+
221+
you can use this method as shown below:
222+
223+
```ts
224+
const hasPermission: PermissionStatus = await checkHasAudioRecorderPermission();
225+
```
226+
227+
#### getAudioRecorderPermission()
228+
229+
This method lets you ask for **NSMicrophoneUsageDescription** permission from user. It will return PermissionStatus.
230+
231+
By combining this and checkHasAudioRecorderPermission you can ask for permission and start recording if permission is granted.
232+
233+
Check the following example for example:
234+
235+
```ts
236+
let hasPermission: PermissionStatus = await checkHasAudioRecorderPermission();
237+
238+
if (hasPermission === PermissionStatus.granted) {
239+
startRecording();
240+
} else if (hasPermission === PermissionStatus.undetermined) {
241+
const permissionStatus = await getAudioRecorderPermission();
242+
if (permissionStatus === PermissionStatus.granted) {
243+
startRecording();
244+
}
245+
} else {
246+
Linking.openSettings();
247+
}
248+
```

you check out the example app for react-native-audio-waveform in [Example](./example/src/App.tsx)
298+
299+
To use example app you need to first run below
300+
301+
```bash
302+
cd example && npx react-native-asset
303+
```
304+
305+
This command will our example audio sample files to iOS bundle so that we can access them inside iOS app.
306+
307+
```sh
308+
yarn
309+
