Fetch YouTube live chat without API

☢ You will need to take full responsibility for your action ☢

Getting started

1. Install
   • npm i youtube-chat
   • yarn add youtube-chat
2. Import
   • Javascript

   const { LiveChat } = require("youtube-chat")

   • Typescript

   import { LiveChat } from "youtube-chat"

3. Create instance with ChannelID or LiveID

   // If channelId is specified, liveId in the current stream is automatically acquired.
   // Recommended
   const liveChat = new LiveChat({channelId: "CHANNEL_ID_HERE"})
   
   // Or specify LiveID in Stream manually.
   const liveChat = new LiveChat({liveId: "LIVE_ID_HERE"})

4. Add events

   // Emit at start of observation chat.
   // liveId: string
   liveChat.on("start", (liveId) => {
     /* Your code here! */
   })
   
   // Emit at end of observation chat.
   // reason: string?
   liveChat.on("end", (reason) => {
     /* Your code here! */
   })
   
   // Emit at receive chat.
   // chat: ChatItem
   liveChat.on("chat", (chatItem) => {
     /* Your code here! */
   })
   
   // Emit when an error occurs
   // err: Error or any
   liveChat.on("error", (err) => {
     /* Your code here! */
   })

5. Start

   // Start fetch loop
   const ok = await liveChat.start()
   if (!ok) {
     console.log("Failed to start, check emitted error")
   }

6. Stop loop

   liveChat.stop()
