Slack Listener for Node-RED (RedBot-Compatible)

A lightweight replacement Slack receiver node for node-red-contrib-chatbot, built to support modern Node.js versions (18+).

This node focuses on compatibility with RedBot-style Slack message formatting while supporting Slack Socket Mode, Block Actions, Slash Commands, and standard messages.

Why this exists

The original Slack receiver in node-red-contrib-chatbot was not compatible with Node.js 18+ without significant changes to the entire chatbot ecosystem.

Instead of upgrading the full stack, this node was created as a drop-in replacement for Slack ingestion only.

Features

• Compatible with RedBot-style message format
• Supports:
  • Slack messages
  • Slash commands
  • Block actions (radio buttons, dropdowns, buttons)
  • Other support not fully tested
• Socket Mode (default), HTTP mode (ExpressReceiver-based, experimental)

Installation

npm install github:@naanatin/node-red-simple-slack-listener

Or inside Node-RED user directory:

cd ~/.node-red
npm install github:@naanatin/node-red-simple-slack-listener

Configuration

Socket Mode (default)

Requires:

• Bot Token (xoxb-...)
• App Token (xapp-...)

Enable Socket Mode in your Slack App settings.

HTTP Mode (experimental)

Requires:

• Bot Token (xoxb-...)
• Signing Secret

Expose endpoint: /slack/events

Output format

The node emits messages in a RedBot-compatible structure:

{
  "originalMessage": {
    "...": ... 
  },
  "payload": {
    "type": "message | response | command",
    "chatId": "...",
    "userId": "...",
    "ts": "timestamp",
    "transport": "slack",
    "inbound": true,
    "content": (parsed value)
  }
}

Notes

• Designed to match RedBot Slack Receiver behavior
• Some edge cases may need tuning

Status

• Socket Mode: stable
• HTTP Mode: experimental
• RedBot compatibility: best-effort
