Welcome to Chapter 3: Component Integration. In this part of Dyad Tutorial: Local-First AI App Building, you will build an intuitive mental model first, then move into concrete implementation details and practical production tradeoffs.
Now that you can build apps with natural language, let's explore how to enhance them with additional components and functionality. Dyad provides a rich component library that you can integrate into your applications.
Components are reusable building blocks that add specific functionality to your apps. They range from simple UI elements to complex features like charts and data tables.
- Navigation: Menus, breadcrumbs, tabs
- Layout: Grids, cards, containers
- Forms: Inputs, selects, checkboxes, date pickers
- Feedback: Modals, tooltips, notifications
- Tables: Sortable, filterable data tables
- Charts: Bar charts, line graphs, pie charts
- Lists: Infinite scroll, search, filtering
- Cards: Product cards, user profiles, content tiles
- Buttons: Various styles and states
- Dropdowns: Multi-select, searchable
- Sliders: Range selectors, volume controls
- Tabs: Content organization
Add a data table component to display user information with sorting and filtering
Include a chart component to visualize sales data with bar and line graphs
Specify component properties:
Add a form with input validation, dropdown menus, and file upload capability
Combine multiple components:
Create a dashboard with:
- Navigation sidebar
- Stats cards in a grid layout
- Data table with pagination
- Chart components for visualization
Apply themes and styles:
Style the components with a dark theme and custom color scheme
Ensure mobile compatibility:
Make all components responsive for mobile and tablet devices
Dyad includes many pre-built components:
- Material UI components
- Ant Design elements
- Custom Dyad components
Add external component libraries:
Integrate React Bootstrap components for additional UI elements
- Use lazy loading for large component libraries
- Optimize component re-renders
- Minimize bundle size with tree shaking
- Ensure components meet WCAG guidelines
- Add proper ARIA labels
- Support keyboard navigation
- Use consistent styling across components
- Follow design system guidelines
- Maintain component naming conventions
- Check component imports
- Verify prop types
- Review console errors
- Inspect CSS conflicts
- Use CSS modules for isolation
- Check component specificity
You've learned how to integrate components into your Dyad applications. In the next chapter, we'll explore data management and database connections.

| Decision Area | Low-Risk Path | High-Control Path | Tradeoff |
|---|---|---|---|
| Runtime mode | managed defaults | explicit policy config | speed vs control |
| State handling | local ephemeral | durable persisted state | simplicity vs auditability |
| Tool integration | direct API use | mediated adapter layer | velocity vs governance |

Most teams struggle here because the hard part is not writing more code, but deciding clear boundaries for components, table, component so behavior stays predictable as complexity grows.
In practical terms, this chapter helps you avoid three common failures:
- coupling core logic too tightly to one implementation path
- missing the handoff boundaries between setup, execution, and validation
- shipping changes without clear rollback or observability strategy
After working through this chapter, you should be able to reason about Chapter 3: Component Integration as an operating subsystem inside Dyad Tutorial: Local-First AI App Building, with explicit contracts for inputs, state transitions, and outputs.
Use the implementation notes around display, user, information as your checklist when adapting these patterns to your own repository.
Under the hood, Chapter 3: Component Integration usually follows a repeatable control path:
- Context bootstrap: initialize runtime config and prerequisites for
components. - Input normalization: shape incoming data so
tablereceives stable contracts. - Core execution: run the main logic branch and propagate intermediate state through
component. - Policy and safety checks: enforce limits, auth scopes, and failure boundaries.
- Output composition: return canonical result payloads for downstream consumers.
- Operational telemetry: emit logs/metrics needed for debugging and performance tuning.
When debugging, walk this sequence in order and confirm each stage has explicit success/failure conditions.

Suggested trace strategy:
- search upstream code for
componentsandtableto map concrete implementation paths - compare docs claims against actual runtime/config code before reusing patterns in production
