App Development
App Development Overview
Before you start building with Digia Studio, it's useful to understand how modern app development works. This section gives you a high-level view of how apps are structured, how they run, and how Digia Studio enhances this development process.
Frontend vs Backend
Every app consists of two main parts:
Frontend – The user interface (UI) that users interact with: screens, buttons, forms, and animations.
Backend – The logic and data layer that powers the app: APIs, databases, authentication, and cloud functions.
The frontend communicates with the backend through API requests. When a user performs an action (like submitting a form), the frontend sends a request to the backend, which responds with the data needed to update the UI.
Where Code Runs
Frontend code runs on the user's device, whether it’s a phone, tablet, or web browser.
Backend code runs on remote servers (cloud or self-hosted), handling data storage, logic, and security.
In Digia Studio’s architecture, the frontend is a lightweight Flutter shell. The actual UI and logic come from a dynamic configuration generated on the server.
Frontend Architecture Patterns
Here are some best practices commonly used in frontend development:
Component-Based Design
Apps are broken into reusable blocks called components — such as headers, cards, buttons, and forms. This improves consistency and maintainability.
State Management
State represents the current condition of the UI (e.g., whether a user is logged in or what data is displayed). Good state management ensures your app updates reliably when things change.
Responsive Layouts
Modern apps need to work on different screen sizes. Responsive design allows layouts to adapt to phones, tablets, or desktops.
Performance Optimization
Fast apps feel better. Optimizing load times, reducing unnecessary renders, and managing large datasets all contribute to better performance.
How Digia Studio Fits In
Digia Studio simplifies and streamlines traditional development with a server-driven approach.
The frontend Flutter shell fetches UI configuration from Digia Studio’s servers at runtime.
All UI, layout, logic, and data connections are defined visually in the Digia Studio dashboard.
When you make a change in the dashboard, it's pushed instantly to live apps — no need to redeploy or go through app store approvals.
You can connect APIs, define logic, and manage design systems—all from a single interface.
Why This Matters
Digia Studio handles the heavy lifting of traditional architecture, enabling you to:
Build interfaces visually, without writing repetitive UI code
Push updates instantly with Digia Hot Reload
Keep backend and frontend loosely coupled but highly coordinated
Focus on your app’s logic and user experience, not boilerplate setup
