> A package to parse WhatsApp chats with Node.js or in the browser 💬

## Important notice

🚨 `v4.0.0` brings some **BREAKING CHANGES**, check out the [release page](https://github.com/Pustur/whatsapp-chat-parser/releases/tag/4.0.0) for more info.

## Introduction

This library allows you to parse WhatsApp chat logs from text format into javascript objects, enabling you to more easily manipulate the data, create statistics, export it in different formats, etc.

You can test the package online with this example website:  
[whatsapp-chat-parser.netlify.app](https://whatsapp-chat-parser.netlify.app/) ([Source code](https://github.com/Pustur/whatsapp-chat-parser-website))

## Install

```
$ npm install whatsapp-chat-parser
```

## Usage

### Node

```js
import fs from 'node:fs';
import * as whatsapp from 'whatsapp-chat-parser';

const text = fs.readFileSync('path/to/_chat.txt', 'utf8');
const messages = whatsapp.parseString(text);

console.log(messages);
```

### Browser

Add the script to your HTML file (usually just before the closing `</body>` tag).  
Then use it in your JavaScript code, the `whatsappChatParser` variable will be globally available.

```html
<script src="path/to/index.global.js"></script>
<script>
  const messages = whatsappChatParser.parseString(
    '06/03/2017, 00:45 - Sample User: This is a test message',
  );

console.log(messages);
</script>
```

Or with `type="module"` loading the ESM version:

```html
<script type="module">
  import * as whatsapp from 'path/to/index.js';

const messages = whatsapp.parseString(
    '06/03/2017, 00:45 - Sample User: This is a test message',
  );

console.log(messages);
</script>
```

You can also use the [jsDelivr CDN](https://www.jsdelivr.com/package/npm/whatsapp-chat-parser).

```html
<script src="https://cdn.jsdelivr.net/npm/whatsapp-chat-parser/dist/index.global.js"></script>

<script src="https://cdn.jsdelivr.net/npm/whatsapp-chat-parser@4.0.2/dist/index.global.js"></script>
```

## Message structure

The `messages` variable is an array of objects like this:

```js
[
  {
    date: '2018-06-02T22:45:00.000Z', // Date object
    author: 'Luke',
    message: 'Hey how are you?',
  },
  {
    date: '2018-06-02T23:48:00.000Z', // Date object
    author: 'Joe',
    message: 'All good, thanks',
  },
];
```

When using the option [`parseAttachments`](#options), the message may contain an additional property `attachment`:

```js
[
  {
    date: '2018-06-02T23:50:00.000Z', // Date object
    author: 'Joe',
    message: '<attached: 00000042-PHOTO-2020-06-07-15-13-20.jpg>',
    attachment: {
      fileName: '00000042-PHOTO-2020-06-07-15-13-20.jpg',
    },
  },
];
```

In the case of a system message, the author will be `null`

```js
[
  {
    date: '2018-06-02T22:45:00.000Z', // Date object
    author: null,
    message: 'You created group "Party 🎉"',
  },
];
```

## API

### parseString(string, [options]) → Array

**string**

Type: `string`

Raw string of the WhatsApp conversation

**options**

Type: `object`

A configuration object, more details below

## Options

## A note about messages order

Sometimes, likely due to connection issues, WhatsApp exports contain messages that are not chronologically ordered.  
This library won't change the order of the messages, but if your application expects a certain order make sure to sort the array of messages accordingly before use.

See [#247](https://github.com/Pustur/whatsapp-chat-parser/issues/247) for more info.
