REACT-NATIVE-COMPRESSOR is a react-native package, which helps us to Compress Image, Video, and Audio before uploading, same like Whatsapp without knowing the compression algorithm

Why should we use react-native-compress over FFmpeg?

We should use react-native-compressor instead of FFmpeg because react-native-compressor gives you same compression of Whatsapp (Image, Video, and Audio) without knowing the algorithm of compression + it is lightweight only increase 50 KB Size Size in APK while FFmpeg increase ~> 9 MB Size in APK, and we have to give manual image/video/Audo size and quality as well as

Usage

Image

Automatic Image Compression Like Whatsapp

import { Image } from 'react-native-compressor';

const result = await Image.compress('file://path_of_file/image.jpg');
// OR
const result = await Image.compress('https://path_of_file/image.jpg', {
  progressDivider: 10,
  downloadProgress: (progress) => {
    console.log('downloadProgress: ', progress);
  },
});

Here is this package comparison of images compression with WhatsApp

Manual Image Compression

import { Image } from 'react-native-compressor';

const result = await Image.compress('file://path_of_file/image.jpg', {
  compressionMethod: 'manual',
  maxWidth: 1000,
  quality: 0.8,
});

Video

Automatic Video Compression Like Whatsapp

import { Video } from 'react-native-compressor';

const result = await Video.compress(
  'file://path_of_file/BigBuckBunny.mp4',
  {},
  (progress) => {
    console.log('Compression Progress: ', progress);
  }
);

//OR

const result = await Video.compress(
  'https://example.com/video.mp4',
  {
    progressDivider: 10,
    downloadProgress: (progress) => {
      console.log('downloadProgress: ', progress);
    },
  },
  (progress) => {
    console.log('Compression Progress: ', progress);
  }
);

Here is this package comparison of video compression with WhatsApp

Manual Video Compression

import { Video } from 'react-native-compressor';

const result = await Video.compress(
  'file://path_of_file/BigBuckBunny.mp4',
  {
    compressionMethod: 'manual',
  },
  (progress) => {
    console.log('Compression Progress: ', progress);
  }
);

Cancel Video Compression

import { Video } from 'react-native-compressor';

let cancellationVideoId = '';

const result = await Video.compress(
  'file://path_of_file/BigBuckBunny.mp4',
  {
    compressionMethod: 'auto',
    // getCancellationId for get video id which we can use for cancel compression
    getCancellationId: (cancellationId) =>
      (cancellationVideoId = cancellationId),
  },
  (progress) => {
    if (backgroundMode) {
      console.log('Compression Progress: ', progress);
    } else {
      setCompressingProgress(progress);
    }
  }
);

// we can cancel video compression by calling cancelCompression with cancel video id which we can get from getCancellationId function while compression
Video.cancelCompression(cancellationVideoId);

Audio

import { Audio } from 'react-native-compressor';

const result = await Audio.compress(
  'file://path_of_file/file_example_MP3_2MG.wav', // recommended wav file but can be use mp3 file
  { quality: 'medium' }
);

// OR

const result = await Audio.compress(
  'file://path_of_file/file_example_MP3_2MG.wav', // recommended wav file but can be use mp3 file
  {
    bitrate: 64000,
    samplerate: 44100,
    channels: 1,
  }
);

Background Upload

import { backgroundUpload } from 'react-native-compressor';

const headers = {};

const uploadResult = await backgroundUpload(
  url,
  fileUrl,
  { httpMethod: 'PUT', headers },
  (written, total) => {
    console.log(written, total);
  }
);

//OR

const uploadResult = await backgroundUpload(
  url,
  fileUrl,
  { uploadType: UploadType.MULTIPART, httpMethod: 'POST', headers },
  (written, total) => {
    console.log(written, total);
  }
);

Cancel Background Upload

for cancellation Upload, there is two ways

1. by calling, cancelUpload function
2. by calling abort function

cancelUpload (support single and all)

import { cancelUpload, backgroundUpload } from 'react-native-compressor';

// if we will call without passing any param then it will remove last pushed uploading
cancelUpload()

// if you pass true as second param then it will cancel all the uploading
cancelUpload("",true)

// if there is multiple files are uploading, and you wanna cancel specific uploading then you pass specific video id like this
let videoId=''
const uploadResult = await backgroundUpload(
  url,
  fileUrl,
  { httpMethod: 'PUT',  getCancellationId: (cancellationId) =>(videoId = cancellationId), },
  (written, total) => {
    console.log(written, total);
  }
);
cancelUpload(videoId)

cancel by calling abort

import { backgroundUpload } from 'react-native-compressor';

const abortSignalRef = useRef(new AbortController());

const uploadResult = await backgroundUpload(
  url,
  fileUrl,
  { httpMethod: 'PUT' },
  (written, total) => {
    console.log(written, total);
  },
  abortSignalRef.current.signal
);

abortSignalRef.current?.abort(); // this will cancel uploading

Download File

import { download } from 'react-native-compressor';

const downloadFileUrl = await download(url, (progress) => {
  console.log('downloadProgress: ', progress);
});

Video Thumbnail

import { createVideoThumbnail, clearCache } from 'react-native-compressor';

const thumbnail = await createVideoThumbnail(videoUri);

await clearCache(); // this will clear cache of thumbnails cache directory

API

Image

ImageCompressor

• compress(value: string, options?: CompressorOptions): Promise<string>

  Compresses the input file URI or base-64 string with the specified options. Promise returns a string after compression has completed. Resizing will always keep the original aspect ratio of the image, the maxWidth and maxHeight are used as a boundary.

CompressorOptions

• compressionMethod: compressionMethod (default: "auto")

  if you want to compress images like whatsapp then make this prop auto. Can be either manual or auto, defines the Compression Method.

• downloadProgress?: (progress: number) => void;

  it is callback, only trigger when we pass image url from server

• progressDivider?: number (default: 0)

  we uses it when we use downloadProgress

• maxWidth: number (default: 1280)

  The maximum width boundary used as the main boundary in resizing a landscape image.

• maxHeight: number (default: 1280)

  The maximum height boundary used as the main boundary in resizing a portrait image.

• quality: number (default: 0.8)

  The quality modifier for the JPEG and PNG file format, if your input file is JPEG and output file is PNG then compressed size can be increase

• input: InputType (default: uri)

  Can be either uri or base64, defines the contentents of the value parameter.

• output: OutputType (default: jpg)

  The quality modifier for the JPEG file format, can be specified when output is PNG but will be ignored. if you wanna apply quality modifier then you can enable disablePngTransparency:true, Note: if you png image have no transparent background then enable disablePngTransparency:true modifier is recommended

• disablePngTransparency: boolean (default: false)

  when user add output:'png' then by default compressed image will have transparent background, and quality will be ignored, if you wanna apply quality then you have to disablePngTransparency like disablePngTransparency:true, it will convert transparent background to white

• returnableOutputType: ReturnableOutputType (default: uri)

  Can be either uri or base64, defines the Returnable output image format.

if you wanna get image metadata (exif) then read this

Video

• compress(url: string, options?: videoCompresssionType , onProgress?: (progress: number)): Promise<string>

• cancelCompression(cancellationId: string): void

  we can get cancellationId from getCancellationId which is the callback method of compress method options

• activateBackgroundTask(onExpired?: (data: any) => void): Promise<any>

  if you wanna compress video while app is in backgroup then you should call this method before compression

• deactivateBackgroundTask(): Promise<any>

  if you call activateBackgroundTask method, then after video compression, you should call deactivateBackgroundTask for disable background task mode.

• getCancellationId: function

  getCancellationId is a callback function that gives us compress video id, which can be used in Video.cancelCompression method to cancel the compression

videoCompresssionType

• compressionMethod: compressionMethod (default: "manual")

  if you want to compress videos like whatsapp then make this prop auto. Can be either manual or auto, defines the Compression Method.

• downloadProgress?: (progress: number) => void;

  it is callback, only trigger when we pass image url from server

• progressDivider?: number (default: 0)

  we uses it when we use downloadProgress/onProgress

• maxSize: number (default: 640)

  The maximum size can be height in case of portrait video or can be width in case of landscape video.

• bitrate: number

  bitrate of video which reduce or increase video size. if compressionMethod will auto then this prop will not work

• minimumFileSizeForCompress: number (default: 0)

  previously default was 16 but now it is 0 by default. 0 mean 0mb. This is an offset, which you can set for minimumFileSizeForCompress will allow this package to dont compress less than or equal to minimumFileSizeForCompress ref #26

if you wanna get video metadata then read this

Audio

• compress(url: string, options?: audioCompresssionType): Promise<string>

  Android: recommended to use wav file as we convert mp3 to wav then apply bitrate

audioCompresssionType

• quality?: qualityType (default: medium)

  we can also control bitrate through quality. qualityType can be low | medium | high

• bitrate?: number Range [64000-320000]

  we can control bitrate of audio through bitrate, it should be in the range of 64000-320000

• samplerate?: number Range [44100 - 192000]

  we can control samplerate of audio through samplerate, it should be in the range of 44100 - 192000

• channels?: number Typically 1 or 2

  we can control channels of audio through channels, Typically 1 or 2

Background Upload

• backgroundUpload: (url: string, fileUrl: string, options: UploaderOptions, onProgress?: ((writtem: number, total: number) => void) | undefined) => Promise< any >

• UploaderOptions

export enum UploadType {
  BINARY_CONTENT = 0,
  MULTIPART = 1,
}

export enum UploaderHttpMethod {
  POST = 'POST',
  PUT = 'PUT',
  PATCH = 'PATCH',
}

export declare type HTTPResponse = {
  status: number;
  headers: Record<string, string>;
  body: string;
};

export declare type HttpMethod = 'POST' | 'PUT' | 'PATCH';

export declare type UploaderOptions = (
  | {
      uploadType?: UploadType.BINARY_CONTENT;
      mimeType?: string;
    }
  | {
      uploadType: UploadType.MULTIPART;
      fieldName?: string;
      mimeType?: string;
      parameters?: Record<string, string>;
    }
) & {
  headers?: Record<string, string>;
  httpMethod?: UploaderHttpMethod;
  getCancellationId?: (cancellationId: string) => void;
};

Note: some of the uploader code is borrowed from Expo I tested file uploader on this backend Nodejs-File-Uploader

Cancel Background Upload

for cancellation Upload, there is two ways, you can use one of it

• cancelUpload: ( uuid?: string, shouldCancelAll?: boolean) => void

  1. If we call without passing any param then it will remove the last pushed uploading
  2. If you pass true as the second param then it will cancel all the uploading
  3. if there is multiple files are uploading, and you wanna cancel specific uploading then you pass a specific video ID like this

• we can use AbortController in backgroundUpload Usage

  const abortSignalRef = useRef(new AbortController());

  abortSignalRef.current?.abort();

Download

• download: ( fileUrl: string, downloadProgress?: (progress: number) => void, progressDivider?: number ) => Promise< string >

Create Video Thumbnail and Clear Cache

• createVideoThumbnail( fileUrl: string, options: {header:Object} ): Promise<{ path: string;size: number; mime: string; width: number; height: number; }>

  it will save the thumbnail of the video into the cache directory and return the thumbnail URI which you can display

• clearCache(cacheDir?: string): Promise< string >

  it will clear the cache that was created from createVideoThumbnail, in future this clear cache will be totally customized

Get Metadata Of Video

if you want to get metadata of video than you can use this function

import { getVideoMetaData } from 'react-native-compressor';

const metaData = await getVideoMetaData(filePath);

{
	"duration": 20.11,
	"extension": "mp4",
	"height": 1080,
	"size": 16940.0,
	"width": 1920
}

• getVideoMetaData(path: string)

Get Metadata Of Image

if you want to get metadata of video than you can use this function

import { getImageMetaData } from 'react-native-compressor';

const metaData = await getImageMetaData(filePath);

{
  "ImageWidth": 4032,
  "ImageHeight": 3024,
  "Orientation": 3,
  "size": 4127057,
  "extension": "jpg",
  "exif":{...}
}

• getImageMetaData(path: string)

Get Real Path

if you want to convert

• content:// to file:/// for android
• ph:// to file:/// for IOS

then you can call getRealPath function like this

import { getRealPath } from 'react-native-compressor';

const realPath = await getRealPath(fileUri, 'video'); //   file://file_path.extension

• getRealPath(path: string, type: string = 'video'|'image')

Get Temp file Path

if you wanna make random file path in cache folder then you can use this method like this

import { generateFilePath } from 'react-native-compressor';

const randomFilePathForSaveFile = await generateFilePath('mp4'); //   file://file_path.mp4

• generateFilePath(fileextension: string)
