Quick Start Examples

Basic Data Access

{{ $json.fieldName }}                    // Get field from current item
{{ $('Node Name').item.json.field }}     // Data from specific node
{{ $json.items?.[0] }}                   // Safe array access

Date Functions

{{ $now.format('YYYY-MM-DD') }}          // 2024-01-15
{{ $now.plus({days: 7}) }}               // 7 days from now
{{ $now.diff('2024-01-01', 'days') }}    // Days between dates

String Manipulation

{{ $json.name.toLowerCase() }}           // convert to lowercase
{{ $json.email.split('@')[0] }}          // Username from email
{{ $json.text.slice(0, 50) }}            // First 50 characters

Array Processing

{{ $json.items.length }}                 // Count array items
{{ $json.items.filter(item => item.active) }}   // Filter items
{{ $json.items.map(item => item.name) }}        // Extract field from all items

Hermes Agent

The self-improving AI agent built by Nous Research. It's the only agent with a built-in learning loop — it creates skills from experience, improves them during use, nudges itself to persist knowledge, searches its own past conversations, and builds a deepening model of who you are across sessions. 

DeerFlow

DeerFlow (Deep Exploration and Efficient Research Flow) is an open-source super agent harness that orchestrates sub-agents, memory, and sandboxes to do almost anything — powered by extensible skills.
