SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill solves the challenge of adding custom server-side functionality to Fusebase Apps when client-side Dashboard SDK capabilities are insufficient, while avoiding common multi-user state bugs, deployment failures, and platform constraint violations.

Core Features & Use Cases

  • Multi-user architecture guidance: Prevents shared state bugs that break multi-user app behavior, with clear rules for per-user vs shared data storage.
  • Full backend setup workflow: Covers Hono framework configuration, REST endpoint creation, WebSocket support, OpenAPI contract maintenance, and fusebase.json backend block setup.
  • Auxiliary service integration: Includes sidecar container setup for tools like headless browsers and caches, plus cron job configuration for scheduled tasks, with strict resource budget compliance.
  • Use case example: If you need to add a custom REST API for business logic validation and real-time WebSocket updates to your Fusebase App, this Skill guides you through every step to ensure the backend is secure, compliant, and production-ready.

Quick Start

Use the app-backend skill to set up a Hono-based backend with REST endpoints, WebSocket support, and the required openapi.json contract for your Fusebase App, including all necessary fusebase.json configuration and multi-user state safety checks.

Frequently Asked Questions about app-backend

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I build a custom REST API backend for my Fusebase App?▼

To build a custom REST API backend for your Fusebase App, configure the Hono framework to create endpoints and maintain the required openapi.json contract for secure, production-ready server-side logic.

When do I need server-side backend logic instead of client-side Dashboard SDK?▼

You need server-side backend logic when the client-side Dashboard SDK lacks sufficient capabilities, specifically for custom REST API creation, WebSocket real-time communication, and scheduled cron job execution.

How do I set up WebSockets for real-time communication in a Fusebase backend?▼

Set up WebSockets for real-time communication in a Fusebase backend by configuring the Hono framework, establishing secure authentication patterns for user-facing routes, and enforcing multi-user state safety rules.

How can I prevent multi-user state bugs when building scalable backends?▼

Prevent multi-user state bugs in scalable backends by applying clear rules for per-user versus shared data storage, enforcing multi-user state safety, and using secure authentication patterns for system routes.

Can I configure scheduled cron jobs and sidecar services in a Fusebase backend?▼

Yes, you can configure scheduled cron jobs and integrate sidecar container services like headless browsers and caches in a Fusebase backend while maintaining strict Azure Container Apps resource budget compliance.

What are the limitations or resource constraints for deploying a Hono backend?▼

Deploying a Hono backend is constrained by Azure Container Apps resource budget limits and requires strict OpenAPI contract synchronization to avoid deployment failures and platform constraint violations.
