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:

``bash


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

`

Note: to run specific versions run:

`sh
npm run wa-source:clean

npm run build:prd

WA_VERSION="2.3000.1029560485" npm run launch:local
`

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

`sh
npm run wa-source:format
`

$3

To compare changes between two WhatsApp Web versions, use the helper script:

Note: You need to run locally in multiple versions to download the scripts to wa-source folder, otherwise will not have anything to compare. To do it use: WA_VERSION="" npm run launch:local

`bash


Compare two versions (overview of module differences)

./scripts/compare-wa-versions.sh 2.3000.1031980585 2.3000.1031992593

Compare a specific module between versions

./scripts/compare-wa-versions.sh 2.3000.1031980585 2.3000.1031992593 WAWebUpdateUnreadChatAction

List available versions

./scripts/compare-wa-versions.sh
`

This is useful for:
- Tracking API changes between WhatsApp Web updates
- Identifying when function signatures changed
- Finding new or removed modules

How to use this project

Basically, you need to inject the wppconnect-wa.js file into the browser after WhatsApp page load.
