Quick Reference

Expression Syntax (expression-syntax/)

// Access current node data
{{$json.fieldName}}
{{$json.body.email}}  // Webhook data is under .body!

// Access other nodes
{{$node["HTTP Request"].json.data}}

// Dates
{{$now.toFormat('yyyy-MM-dd')}}

Files:

• SKILL.md — Core syntax guide
• EXAMPLES.md — Common expression examples
• COMMON_MISTAKES.md — Pitfalls to avoid

---

JavaScript Code (javascript-code/)

// Basic Code node template
const items = $input.all();

const processed = items.map(item => ({
  json: {
    ...item.json,
    processed: true
  }
}));

return processed;  // MUST return [{json: {...}}] format

Files:

• SKILL.md — Core guidance
• DATA_ACCESS.md — $input, $json patterns
• BUILTIN_FUNCTIONS.md — $helpers.httpRequest(), DateTime
• COMMON_PATTERNS.md — Reusable code snippets
• ERROR_PATTERNS.md — Debugging help

---

Node Configuration (node-configuration/)

Philosophy: Progressive disclosure — start minimal, add complexity

1. get_node_essentials — Use first (91.7% success rate)
2. get_property_dependencies — For complex nodes
3. get_node_info — Full schema when needed

Files:

• SKILL.md — Core concepts
• OPERATION_PATTERNS.md — Node-specific patterns
• DEPENDENCIES.md — Property dependency chains

Firefrost n8n Use Cases

Workflow	Description
Subscription sync	Stripe → Discord role assignment
Server monitoring	Pterodactyl → Discord alerts
Backup notifications	Server backup status → Discord
Welcome automation	New subscriber → Welcome email/DM

---

Common Pitfalls

1. Webhook data location: Data is in $json.body, not $json directly
2. Return format: Code nodes MUST return [{json: {...}}]
3. Node names: Case-sensitive, must match exactly
4. Expression braces: Use {{}} not {}
