# Baileys
Reverse Engineered WhatsApp Web API in Node.js
Thank you to [Sigalor](https://github.com/sigalor/whatsapp-web-reveng) for writing the guide reverse engineering WhatsApp Web and to the go reimplementation written by [Rhymen](https://github.com/Rhymen/go-whatsapp/tree/484cfe758705761d76724e01839d6fc473dc10c4)
To use Baileys: ``` js const WhatsAppWeb = require('Baileys') ```
Check out test.js to see exactly how to use Baileys.
# Note
I am in no way affiliated with WhatsApp. This is purely for educational purposes.

@protobufjs/codegen
===================
[![npm](https://img.shields.io/npm/v/@protobufjs/codegen.svg)](https://www.npmjs.com/package/@protobufjs/codegen)
A minimalistic code generation utility.
API
---
* **codegen([functionParams: `string[]`], [functionName: string]): `Codegen`**<br />
Begins generating a function.
* **codegen.verbose = `false`**<br />
When set to true, codegen will log generated code to console. Useful for debugging.
Invoking **codegen** returns an appender function that appends code to the function's body and returns itself:
* **Codegen(formatString: `string`, [...formatParams: `any`]): Codegen**<br />
Appends code to the function's body. The format string can contain placeholders specifying the types of inserted format parameters:
* `%d`: Number (integer or floating point value)
* `%f`: Floating point value
* `%i`: Integer value
* `%j`: JSON.stringify'ed value
* `%s`: String value
* `%%`: Percent sign<br />
* **Codegen([scope: `Object.<string,*>`]): `Function`**<br />
Finishes the function and returns it.
* **Codegen.toString([functionNameOverride: `string`]): `string`**<br />
Returns the function as a string.
Example
-------
```js
var codegen = require("@protobufjs/codegen");
var add = codegen(["a", "b"], "add") // A function with parameters "a" and "b" named "add"
("// awesome comment") // adds the line to the function's body
("return a + b - c + %d", 1) // replaces %d with 1 and adds the line to the body
({ c: 1 }); // adds "c" with a value of 1 to the function's scope
console.log(add.toString()); // function add(a, b) { return a + b - c + 1 }
console.log(add(1, 2)); // calculates 1 + 2 - 1 + 1 = 3
```

[![npm](https://img.shields.io/npm/v/@protobufjs/float.svg)](https://www.npmjs.com/package/@protobufjs/float)
Reads / writes floats / doubles from / to buffers in both modern and ancient browsers. Fast.
API
---
* **writeFloatLE(val: `number`, buf: `Uint8Array`, pos: `number`)**<br />
Writes a 32 bit float to a buffer using little endian byte order.
* **writeFloatBE(val: `number`, buf: `Uint8Array`, pos: `number`)**<br />
Writes a 32 bit float to a buffer using big endian byte order.
* **readFloatLE(buf: `Uint8Array`, pos: `number`): `number`**<br />
Reads a 32 bit float from a buffer using little endian byte order.
* **readFloatBE(buf: `Uint8Array`, pos: `number`): `number`**<br />
Reads a 32 bit float from a buffer using big endian byte order.
* **writeDoubleLE(val: `number`, buf: `Uint8Array`, pos: `number`)**<br />
Writes a 64 bit double to a buffer using little endian byte order.
* **writeDoubleBE(val: `number`, buf: `Uint8Array`, pos: `number`)**<br />
Writes a 64 bit double to a buffer using big endian byte order.
* **readDoubleLE(buf: `Uint8Array`, pos: `number`): `number`**<br />

Reads a 64 bit double from a buffer using big endian byte order.
Performance
-----------
There is a simple benchmark included comparing raw read/write performance of this library (float), float's fallback for old browsers, the [ieee754](https://www.npmjs.com/package/ieee754) module and node's [buffer](https://nodejs.org/api/buffer.html). On an i7-2600k running node 6.9.1 it yields:
```

προλαβεῖν ἡμῖν εἶναι τὴν πρώτην, ὅπως τοὺς συμμάχους

[----------------------------|------------------------]
๏ แผ่นดินฮั่นเสื่อมโทรมแสนสังเวช พระปกเกศกองบู๊กู้ขึ้นใหม่
สิบสองกษัตริย์ก่อนหน้าแลถัดไป สององค์ไซร้โง่เขลาเบาปัญญา
ทรงนับถือขันทีเป็นที่พึ่ง บ้านเมืองจึงวิปริตเป็นนักหนา
โฮจิ๋นเรียกทัพทั่วหัวเมืองมา หมายจะฆ่ามดชั่วตัวสำคัญ
เหมือนขับไสไล่เสือจากเคหา รับหมาป่าเข้ามาเลยอาสัญ
ฝ่ายอ้องอุ้นยุแยกให้แตกกัน ใช้สาวนั้นเป็นชนวนชื่นชวนใจ
พลันลิฉุยกุยกีกลับก่อเหตุ ช่างอาเพศจริงหนาฟ้าร้องไห้
ต้องรบราฆ่าฟันจนบรรลัย ฤๅหาใครค้ำชูกู้บรรลังก์ ฯ

ሰማይ አይታረስ ንጉሥ አይከሰስ።
ብላ ካለኝ እንደአባቴ በቆመጠኝ።
ጌጥ ያለቤቱ ቁምጥና ነው።

የአፍ ወለምታ በቅቤ አይታሽም።
አይጥ በበላ ዳዋ ተመታ።
ሲተረጉሙ ይደረግሙ።
ቀስ በቀስ፥ ዕንቁላል በእግሩ ይሄዳል።
ድር ቢያብር አንበሳ ያስር።
ሰው እንደቤቱ እንጅ እንደ ጉረቤቱ አይተዳደርም።
እግዜር የከፈተውን ጉሮሮ ሳይዘጋው አይድርም።
የጎረቤት ሌባ፥ ቢያዩት ይስቅ ባያዩት ያጠልቅ።
ሥራ ከመፍታት ልጄን ላፋታት።
ዓባይ ማደሪያ የለው፥ ግንድ ይዞ ይዞራል።
የእስላም አገሩ መካ የአሞራ አገሩ ዋርካ።
ተንጋሎ ቢተፉ ተመልሶ ባፉ።
ወዳጅህ ማር ቢሆን ጨርስህ አትላሰው።
እግርህን በፍራሽህ ልክ ዘርጋ።
