This skill provides expert guidance for writing JavaScript code within n8n Code nodes. It covers using $input, $json, and $node syntax, making HTTP requests with $helpers, and working with dates using DateTime. It helps with troubleshooting Code node errors and choosing between Code node modes. Use this for complex transformations, custom calculations, recursive operations, and data aggregation that simple nodes cannot handle.

This skill covers designing visible and recoverable error handling for n8n workflows. It focuses on using error outputs, retry mechanisms, and Error Trigger workflows to prevent silent failures in unattended automation. Learn how to configure node-level retries and wire error paths correctly to ensure alerts and diagnostics are exposed only when necessary.

Use this skill for implementing or debugging network requests, API calls, and data fetching in React Native and Expo projects. Covers fetch API, React Query, SWR, caching strategies, offline support, and Expo Router data loaders. Essential for handling authentication, environment variables, and network errors effectively.

S3-compatible object storage that branches alongside your Neon Postgres project, keeping files and database rows in sync across dev, preview, and production environments via copy-on-write buckets.

This skill generates ready-to-use CI/CD pipeline configurations for automated API testing using Newman. It supports multiple platforms including GitHub Actions, GitLab CI, Jenkins, Azure DevOps, and CircleCI. Users can specify collection sources, environment variables, and report formats like JUnit or HTML. The generated scripts install Newman and execute Postman collections within the pipeline, ensuring consistent API quality checks across different development environments.

A comprehensive guide providing best practices and architectural patterns for modern full-stack development using Next.js 14+ App Router. Covers advanced topics like Server Components, efficient data fetching, handling parallel routes, and implementing full-stack features with Server Actions for scalable React applications.

Master Next.js App Router development with guidelines on Server Components, data fetching strategies, routing patterns, and performance optimization. Learn to structure projects, handle API routes, and implement caching effectively for scalable web applications.

This skill provides comprehensive guidance for building scalable, maintainable, and production-ready backend applications using Node.js. It covers modern architectural patterns, best practices, and implementation details for REST APIs, GraphQL servers, microservices, authentication, real-time WebSockets, and complex database integrations (SQL/NoSQL).

Master Node.js development principles for 2025, covering framework selection, architecture design, async patterns, validation, and security. Focuses on decision-making logic rather than code memorization to help build scalable and secure applications effectively.

Expert guidance for designing distributed NoSQL databases like Cassandra and DynamoDB. Covers query-first modeling, partition key selection, single-table design, denormalization, and avoiding hot partitions in high-scale systems.

This skill covers configuring and managing object storage solutions like AWS S3, MinIO, and GCS. It includes CLI operations for bucket management, uploading/downloading files, setting up versioning, implementing bucket policies for access control, and configuring lifecycle rules for cost optimization. Suitable for DevOps engineers managing application assets, backups, logs, and media files in cloud or on-premises environments.

This skill enables building production-ready monitoring, logging, and tracing systems for enterprise applications. It covers implementing observability strategies, managing SLIs and SLOs, and handling incident response workflows. Expertise includes distributed tracing, log management, alerting, and reliability engineering practices using tools like Prometheus, Grafana, and OpenTelemetry to ensure system stability and performance.
