n8n Node Reference Workflow

This n8n workflow serves as a comprehensive visual reference library for various n8n nodes, primarily focusing on core functionalities, AI/Langchain integrations, and common app nodes. It's designed to help users quickly identify and understand the purpose and category of a wide array of n8n nodes.

What it does

This workflow is purely a visual documentation tool. It contains a collection of n8n nodes, organized by their categories and types, demonstrating the breadth of integrations and functionalities available within n8n. There are no active connections or operational logic within this workflow; its sole purpose is to serve as a static, browsable catalog of nodes.

The workflow showcases nodes from the following categories:

• Triggers: Demonstrates various ways a workflow can be initiated (e.g., Webhook, Schedule, Email, Google Drive, Calendly, Gumroad, Form, Chat).
• Data & Storage: Includes nodes for interacting with services like Dropbox, Google Sheets, Google Drive, and FTP.
• Communication: Features nodes for Email (IMAP), Gmail, Pushbullet, Reddit, and X (formerly Twitter).
• Productivity: Highlights nodes for Google Sheets, Google Calendar, and Calendly.
• Development / Core Nodes: Covers fundamental nodes for logic (If, Merge, Loop Over Items, Filter), data manipulation (Edit Fields, Rename Keys, Convert to File, Extract from File, Aggregate, Limit, Remove Duplicates, Split Out, Sort, Summarize, HTML, Markdown, Code, AI Transform), external interactions (HTTP Request, Execute Command), and workflow management (Execute Sub-workflow, Respond to Webhook, Wait, No Operation, Execution Data).
• AI / Langchain: Showcases a wide range of AI-related nodes, including:
  • Agents: AI Agent.
  • Chains: Summarization Chain, Basic LLM Chain, Question and Answer Chain, Text Classifier, Information Extractor, Sentiment Analysis.
  • Embeddings: Embeddings OpenAI, Embeddings Google Gemini.
  • Language Models: OpenAI Chat Model, Anthropic Chat Model, Google Gemini Chat Model.
  • Memory: Simple Memory, Redis Chat Memory, Postgres Chat Memory.
  • Output Parsers: Auto-fixing Output Parser, Item List Output Parser, Structured Output Parser.
  • Tools: Calculator, Code Tool, SerpApi (Google Search), Wikipedia, Wolfram|Alpha, Call n8n Workflow Tool, HTTP Request Tool, Vector Store Question Answer Tool, MCP Client Tool.
  • Vector Stores: Simple Vector Store, Pinecone Vector Store, Supabase Vector Store, Postgres PGVector Store.
  • Document Loaders: Default Data Loader.
  • Miscellaneous: Chat Memory Manager.
• Marketing: Includes X (formerly Twitter) and YouTube nodes.
• Sales: Features Gumroad Trigger.
• Utility: Contains Bitly, Respond to Webhook, and FTP nodes.

Prerequisites/Requirements

• n8n Instance: An active n8n instance (self-hosted or cloud).
• No specific credentials required for this workflow: Since this workflow is for reference only and does not execute, no credentials are strictly required to import and view it. However, if you were to build functional workflows using these nodes, you would need:
  • API keys/credentials for various services (e.g., OpenAI, Google, Anthropic, Bitly, Gumroad, Pinecone, Supabase, Redis, Postgres, SerpApi, Wolfram|Alpha, X, Dropbox, Calendly, IMAP).
  • Access to specific services (e.g., Google Sheets, Google Calendar, Google Drive, Gmail, Pushbullet, Reddit, YouTube, FTP).

Setup/Usage

1. Import the workflow: Download the JSON file and import it into your n8n instance.
2. Explore the nodes: Once imported, you can browse the workflow canvas to see all the included nodes. Each node is placed on the canvas for visual inspection.
3. Understand node capabilities: Click on individual nodes to open their configuration panels. While not configured to run, these panels will display all available options, operations, and parameters for each node, allowing you to understand its capabilities without needing to set up credentials or build a functional flow.
4. Reference for building: Use this workflow as a quick reference when planning or building your own n8n workflows to identify suitable nodes for your automation needs.
