n8n-nodes-veritheia

This is a collection of n8n nodes developed by Veritheia.

YAML Validator Node

The YAML Validator node allows you to validate data against a schema defined in YAML format. The node uses Zod for schema definition and validation.

Features

• Define complex validation schemas using YAML
• Two output branches: one for valid data, one for invalid data
• Comprehensive error reporting

Installation

npm install n8n-nodes-veritheia

Usage

1. Add the YAML Validator node to your workflow
2. Configure the schema using the YAML Schema field
3. Specify the input data field name
4. Connect your data source to the node's input
5. Connect the "Valid" output to nodes that handle valid data
6. Connect the "Invalid" output to nodes that handle invalid data
