Android

1. Create a contents.json file in yourproject -> android -> app -> src -> main -> assets following the following scheme. Improtant! Including dots in the identifier is causing troubles.

{
  "android_play_store_link": "https://play.google.com/store/apps/details?id=com.myapp",
  "ios_app_store_link": "https://itunes.apple.com/app/myapp/id123456",
  "sticker_packs": [
    {
      "identifier": "myprojectstickers",
      "name": "MyProject Stickers",
      "publisher": "John Doe",
      "tray_image_file": "tray_icon.png",
      "publisher_email": "[email protected]",
      "publisher_website": "https://myproject.com",
      "privacy_policy_website": "https://myproject.com/legal",
      "license_agreement_website": "https://myproject.com/license",
      "stickers": [
        {
          "image_file": "01_sticker.webp",
          "emojis": ["✌️"]
        },
        {
          "image_file": "02_sticker.webp",
          "emojis": ["😍","😻"]
        },
        {
          "image_file": "03_sticker.webp",
          "emojis": ["😎"]
        }
      ]
    }
  ]
}

2. Place the WebP images in a folder with with the same name that you defined as identifier in the object above under the same directory. So your assets folder has the following structure:

assets
+-- contents.json
+-- identifier
|   +-- 01_sticker.webp
|   +-- 02_sticker.webp
|   +-- 03_sticker.webp

3. Add noCompress to your app build.gradle in yourproject -> android -> app

android {
    ...
    aaptOptions {
        noCompress "webp"
    }
    ...

Done 🎉

Usage

Methods

Check if WhatsApp is available

RNWhatsAppStickers.isWhatsAppAvailable()
  .then(isWhatsAppAvailable => console.log('available:', isWhatsAppAvailable))
  .catch(e => console.log(e))

iOS

1. Create a sticker pack

import RNWhatsAppStickers from "react-native-whatsapp-stickers"

const config = {
  identifier: '',
  name: '',
  publisher: '',
  trayImageFileName: '',
  publisherEmail: '',
  publisherWebsite: '',
  privacyPolicyWebsite: '',
  licenseAgreementWebsite: '',
}

RNWhatsAppStickers.createStickerPack(config)
  .then(() => console.log('success'))
  .catch(e => console.log(e))

2. Add sticker

RNWhatsAppStickers.addSticker('stickername.png', ['😎'])
  .then(() => console.log('success'))
  .catch(e => console.log(e))

3. Send to WhatsApp

RNWhatsAppStickers.send()
  .then(() => console.log('success'))
  .catch(e => console.log(e))

Android

You are already good to go with the sticker pack creation if you followed the Integration part.

1. Send to WhatsApp where name and identifier represent the values you defined in contents.json

RNWhatsAppStickers.send('identifier', 'name')
  .then(() => console.log('success'))
  .catch(e => console.log(e))

Example

App.js

import { Platform } from "react-native";
import RNWhatsAppStickers from "react-native-whatsapp-stickers"
import { stickerConfig } from "./stickerConfig"

const { stickers, ...packConfig } = stickerConfig

RNWhatsAppStickers.isWhatsAppAvailable()
  .then(isWhatsAppAvailable => {
    if (isWhatsAppAvailable) {
      if (Platform.OS === 'ios') {
        return RNWhatsAppStickers.createStickerPack(packConfig)
          .then(() => {
            const promises = stickers.map(item =>
              RNWhatsAppStickers.addSticker(item.fileName, item.emojis)
            )
            Promise.all(promises).then(() => RNWhatsAppStickers.send())
          })
          .catch(e => console.log(e))
      }

      return RNWhatsAppStickers.send('myprojectstickers', 'MyProject Stickers')
    }

    return undefined
  })
  .catch(e => console.log(e))

stickerConfig.js

export const stickerConfig = {
  identifier: 'myprojectstickers',
  name: 'MyProject Stickers',
  publisher: 'John Doe',
  trayImageFileName: 'tray_icon.png',
  publisherEmail: '[email protected]',
  publisherWebsite: 'https://myproject.com',

Troubleshooting

ld: warning: Could not find auto-linked library 'swiftFoundation'

• Create an empty swift file in your project

xCode -> Click File -> new File -> empty.swift

Important Click yes when it asks for creating bridge-headers

Roadmap

• Native implementation of method to check if WhatsApp is installed
• Consistend react-native api
