Apr 19, 2025

Beginner Course on Nen - Video 3: Understanding Nodes

Overview

  • Focus on understanding Niden nodes, the fundamental components in Nen workflows.
  • Nodes are essential for building workflows by connecting them sequentially.

Categories of Nodes

  1. Entry Points
    • Serve as triggers to initiate workflows.
  2. Functions
    • Transform, filter, or format data.
  3. Exit Points
    • Connect to applications or services.

Types of Nodes

  • Triggers
  • Actions
  • In-app data
  • Transfer information (filter, flow files)
  • Advanced nodes

Example: Google Sheets Node

  • Start with an empty canvas in Nen.
  • Add nodes by clicking "Add first step" or the plus button.
  • First node must be a trigger.
  • Manual trigger can be used to start the workflow.
  • Search and select nodes quickly by typing names.
  • Select specific actions (operations) for nodes.

Node Configuration

  • Parameters: Default view with node-specific configurations, e.g., selecting a spreadsheet for operations like "get rows".
  • Credentials: Important for authenticating access to applications and services.
    • Credentials are saved at an instance level and can be shared selectively.

Input and Output Data

  • View input and output data for nodes.
  • Table View: Displays data in columns and rows.
  • JSON View: Shows data as key-value pairs.
  • Schema View: Shows keys and example values.

Steps to Add and Configure a Node

  1. Adding a Node:
    • Use the plus button or search for specific nodes.
    • Select actions for nodes (e.g., "Get rows" for Google Sheets).
  2. Setting Up Credentials:
    • Use OAuth or service accounts to authenticate.
    • Sign in with Google to connect and read data.
  3. Select Document and Sheet:
    • Choose the document and sheet to act upon.
  4. Execute the Node:
    • View the output data on the right.

Advanced Settings

  • Node settings are node-independent.
  • Configure settings related to execution, output, error handling, etc.
  • Advanced Options:
    • Filtering data, managing data location and formatting.
    • Handle multiple matches in filters.

Conclusion

  • Nodes are crucial for building workflows in Nen.
  • Next video will delve into data types used by Nen nodes and data flow in workflows.
  • Aim to understand and create effective workflows.
