🔗 Common Workflow Patterns

Pattern 1: Web Scraping Pipeline

anti-scraping → html-parsing → data-processing → data-export

Use for: E-commerce scraping, content collection, price monitoring

Pattern 2: AI Content Analysis

input → ai-integration → notion-operations

Use for: Content analysis, auto-tagging, knowledge management

Pattern 3: Video Intelligence

oauth-automation → video-processing → ai-integration → notion-operations

Use for: Video indexing, show notes, content summarization

Pattern 4: Link Collection

webhook → notion-link-analysis → notion database

Use for: Research, content curation, inspiration collection

Pattern 5: Database Sync

schedule → notion-database-sync → target database

Use for: Cross-database synchronization, data migration

💡 Tips for Success

Golden Rules

• Check Best Practices FIRST - Saves hours of debugging

• Use ES5 syntax only - No arrow functions, template literals

• Use require('https')

• Not $http or axios

• Export environment variables - Don't just source

• Preserve data flow - Always spread previous data

Common Mistakes to Avoid

• ❌ Using ES6 syntax in Code nodes

• ❌ Using $http for HTTP requests

• ❌ Not exporting environment variables

• ❌ Losing upstream data in transformations

• ❌ Hardcoding credentials

When Stuck

• Check n8n-best-practices/README.md

• Search relevant skill documentation

• Check error message against known issues

• Test code outside n8n first

• Simplify workflow to isolate problem
