Message Reaction Feature

Overview

This feature allows you to make Miku react to any message in Discord with a specific emoji of your choice through the Web UI.

Navigate to the Actions Tab
- Open the Miku Control Panel (http://your-server:3939)
- Click on the "Actions" tab
Find the "Add Reaction to Message" Section
- Scroll down to find the "😊 Add Reaction to Message" section
Fill in the Required Information
- Message ID: Right-click on the target message in Discord → "Copy ID"
- Channel ID: Right-click on the channel name → "Copy ID"
- Emoji: Enter the emoji you want Miku to react with (e.g., 💙, 👍, 🎉)
Click "Add Reaction"
- Miku will add the specified reaction to the message
- You'll see a success confirmation message

Discord Developer Mode: You need to enable Developer Mode in Discord to copy message and channel IDs
- Settings → Advanced → Developer Mode (toggle ON)

Standard Unicode Emoji: 💙, 👍, 🎉, ❤️, etc.
Custom Server Emoji: Use the format :emoji_name: for custom Discord emojis

If you want to integrate this programmatically:

POST /messages/react
Content-Type: multipart/form-data

message_id: <Discord message ID>
channel_id: <Discord channel ID>
emoji: <emoji string>

Success:

{
  "status": "ok",
  "message": "Reaction 💙 queued for message 123456789"
}

Error:

{
  "status": "error",
  "message": "Channel 123456789 not found"
}

"Channel not found": Make sure Miku is in the server that contains that channel
"Message not found": Verify the message ID is correct and still exists
"Permission denied": Miku needs the "Add Reactions" permission in that channel
Invalid emoji: Make sure you're using a valid emoji format

The reaction is added asynchronously by the Discord bot
The Web UI receives immediate confirmation that the request was queued
If the reaction fails (e.g., due to permissions), an error will be logged in the bot logs
