Chat Parser

An issue we're running to at StreamJar is everybody handles their chats completely different. Which when you want to support lots of different services in the same way, it can cause less than ideal situations.

Quick Note.

Smashcast has some interesting quirks.. in order to parse user ids, you must set a function sc.setUserIdentifier() which takes a function from username to id.

Installation

To install, simply install it via NPM.

npm install --save chat-parser

Getting Started

Getting started is simple. Require the module, create a new instance.. and parse.

import { MixerParser } from 'chat-parser';

const parser = new MixerParser({ developers: ['1'], bots: ['2'] });

parser.parse({
    // raw message
}, 'bot-username'),them(msg => { /* */ });

Expected object

This module expects slightly different things depending on the platform (look in /examples for example objects).

• For Mixer, pass the data portion of the ChatMessage packet.
• For Twitch, pass the PRIVMSG as a string.
• For Smashcast, pass the "params" part of the chat packet.

Parsed Message

The parsed message contains basic user information and the message itself.

{
    "user": {
        "userId": 373,
        "username": "Luke",
        "roles": [ Role{ role: 'Owner', level: 50 }],
        "primaryRole": Role{ role: 'Owner', level: 50 },
    },
    'metadata": {
        "command": false,
        "commandName": "give",
        "description": '@Luke 100',
    },
    "message": [
        {
            "type": 'text',
            "text": "hello",
        }
    ]
}

Types of message

Currently there are 4 types of message. Text, link, mention and emoticon.

Text:

{
    "type": "text",
    "text": "hello"
}

Link:

{
    "type": "link",
    "text": "https://google.com",
    identifier: "https://google.com",
}

Mention:

{
    "type": "mention",
    "text": "@StreamJar",
    identifier: "StreamJar",
}

Emoticon

Emoticons are handled differently between Twitch/Smashcast and Mixer, we call this 'sprite' and 'direct'.

Sprite:

{
    "type":"emoticon",
    "text":":D",
    "identifier":{
    "type":"sprite",
    "pack":"https://mixer.com/_latest/emoticons/default.png",
    "coords":{
        "x":72,
        "y":0,
        "width":24,
        "height":24
    }
}

Direct:

{
    "type":"emoticon",
    "text":":D",
    "identifier":{
    "type":"direct",
    "url":"https://smashcast.tv/static/img/chat/default/lol1.png"
}

Discord

Discord is slightly special since we have no clue how you're getting the data. We assume all other platforms are the raw wire format, but we expect you to provide an implementation of IDiscordRawPacket.
