About fullstack-dev

The 'fullstack-dev' skill is designed to guide developers through building robust full-stack applications, providing structured practices for backend architecture and frontend-backend integration. It addresses common challenges in full-stack development such as coordinating service layers, implementing authentication, handling errors, integrating real-time features, and ensuring production readiness. By following a systematic workflow, developers can scaffold, implement, test, and deliver applications efficiently while adhering to best practices from established software architecture principles.

This skill offers capabilities including guidance on project structuring, API client patterns, authentication strategies, real-time communication methods, and typed error handling. It integrates knowledge from references like the Twelve-Factor App, Clean Architecture, Domain-Driven Design, and Patterns of Enterprise Application Architecture. It also emphasizes verifying builds, performing integration checks, and conducting real-time synchronization tests. The workflow ensures that developers make informed architectural decisions, scaffold correctly, implement features according to proven patterns, and deliver a tested, production-ready solution.

The primary use cases include building CRUD applications, real-time chat apps, and other interactive full-stack solutions with frameworks such as Express + React, Next.js, Node.js, Python, and Go. Target users are developers aiming to implement full-stack projects with strong architectural discipline, including those working with APIs, authentication flows, file uploads, and real-time features. This skill is ideal for teams or individual developers seeking a repeatable, comprehensive process to deliver maintainable and production-ready full-stack applications.

FAQ

Which technology stacks are supported by this skill?

It supports a variety of stacks including Express + React, Next.js API, Node.js backend, Python backend, and Go backend. Users can also specify different frontend-backend combinations as needed.

Can this skill be used for pure frontend or styling tasks?

No, the skill is specifically designed for full-stack development and backend integration. It should not be triggered for pure frontend UI work, CSS styling, or database schema-only tasks.

Does this skill handle real-time communication?

Yes, it provides guidance for implementing real-time features using SSE, WebSocket, or polling, including instructions for testing synchronization across clients.

What authentication methods are recommended?

Supported authentication strategies include JWT with refresh tokens, session-based auth, OAuth, and third-party services like Clerk or Auth.js, depending on the application's requirements.

Are there testing and verification steps included?

Yes, the workflow includes build checks, integration checks between frontend and backend, real-time feature testing, and a smoke test to ensure endpoints return expected responses before deployment.
