How does it work

This project extracts some functions of WhatsApp sources.

After build, this project generates a file dist/wppconnect-wa.js to be used for injection in WhatsApp Web. When injected, it will expose a global variable named WPP.

Some parts of WPP variable:

• WPP.webpack - Scripts to export WhatsApp functions.
• WPP.whatsapp - Only exported WhatsApp functions.
• WPP.chat - Chat functions and events.
• ...

Exported WhatsApp modules

There are convention names for some exported modules:

• ...Model - Class for data structure (ClassModel, MsgModel)
• ...Collection - Class for collection of models (ChatCollection, MsgCollection)
• ...Store - Default and global instance of a collection (ChatStore, MsgStore)

Development

Steps to run locally:

# install the dependencies
npm install

# build javascript files
npm run build:prd # or build:dev for development

# launch a local browser with automatic injection
# this will also cache the files inside wa-source directory, for next requests
npm run launch:local

# or only run in VSCode
Copy

Note: to run specific versions run:

npm run wa-source:clean

npm run build:prd

WA_VERSION="2.3000.1029560485" npm run launch:local
Copy

To debug or inspect wa-source folder, format the files to be easier to understand

npm run wa-source:format
