LLM Plugin for Node-RED

LLM Plugin is a Node-RED sidebar extension for chatting with LLMs, generating/modifying flows, and importing results into the active tab.

Install

npm install @background404/node-red-contrib-llm-plugin

Restart Node-RED after install.

Quick Start

1. Open the LLM Plugin sidebar.
2. Configure provider in Settings:

• Ollama: set URL (default http://localhost:11434)
• OpenAI: set API key

3. Enter model and prompt.
4. Enable Send current flow to include active-tab context.
5. Use Agent mode for auto-apply, or Ask mode for manual import.
6. Apply strategy is decided by the model (applyMode) and enforced by the importer (safe fallback: edit-only).

Recommended Usage

For custom/community nodes, keep a small sample flow in the active tab and enable Send current flow. The model then follows real node/property patterns from that sample instead of relying on fixed per-node prompt rules.

Flow Import

• Supports Vibe Schema and raw Node-RED JSON.
• Accepts mixed response text + JSON (with or without code fences).
• Preserves robust parsing when function code contains comment tokens in JSON strings.
• Agent mode supports connection updates, LLM-driven deletions, and checkpoint-based restore.
• Apply mode is model-driven via top-level applyMode (edit-only, merge, overwrite, delete-only).

Notes

• This plugin is under active development.
• Model output quality varies by model and prompt.
