It covers module loading, data binding, component initialization, event handling, form creation, and tooling integration. + +## 1. Module Loading - CRITICAL + +### Never Use Global Access + +**NEVER** access UI5 framework objects globally (e.g., `sap.m.Button`). Always declare dependencies explicitly for asynchronous loading. + +#### JavaScript +```javascript +// ❌ WRONG - Global access +var oButton = new sap.m.Button(); + +// ✅ CORRECT - Explicit dependency +sap.ui.define(["sap/m/Button"], function(Button) { + var oButton = new Button(); +}); +``` + +#### TypeScript +```typescript +// ❌ WRONG - Global namespace +const button: sap.m.Button; + +// ✅ CORRECT - Import module +import Button from "sap/m/Button"; +const button: Button; +``` + +#### XML Views +```xml + + + + + +``` + +**Why**: Ensures proper async loading, improves performance, and enables tree-shaking in production builds. + +### Dynamic Module Loading + +```javascript +// ❌ Old style +sap.ui.require(["sap/m/MessageBox"], function(MessageBox) { + MessageBox.show("Hello"); +}); + +// ✅ Modern style (TypeScript/ES6) +import("sap/m/MessageBox").then((MessageBox) => { + MessageBox.default.show("Hello"); +}); +``` + +## 2. Component Initialization + +**ALWAYS** use `sap/ui/core/ComponentSupport` for declarative initialization: + +```html + + + + +
+
+ +``` + +**Why**: Enables clean separation, supports async loading, and follows SAP's recommended pattern. + +## 3. Data Binding Best Practices + +### Always Use Built-in Data Types + +**Priority order**: +1. OData types (`sap/ui/model/odata/type/*`) - **Preferred** +2. Simple types (`sap/ui/model/type/*`) - Only when no OData equivalent +3. Custom formatters - Only for unique business logic + +```xml + + + + + + + + +``` + +**Common OData Types**: +- `sap/ui/model/odata/type/Decimal` - Numbers with decimals +- `sap/ui/model/odata/type/String` - Text with length constraints +- `sap/ui/model/odata/type/DateTime` - Date and time +- `sap/ui/model/odata/type/Boolean` - True/false values + +### Data Binding in Views + +**ALWAYS** use data binding to connect controls to models: + +```xml + + + + + + + + + + +``` + +## 4. Form Creation Rules + +### Never Use SimpleForm Unless Explicitly Requested + +```xml + + + + + + + + + + + + + + + + + + + + + +``` + +**Default Columns**: +- M-size: 2 columns +- L-size: 3 columns +- XL-size: 4 columns + +## 5. Internationalization (i18n) + +### Apply Changes to ALL Locales + +When modifying `.properties` files, **ALWAYS** update all locale variants: + +```bash +# If you add to i18n.properties: +title=Customer List + +# Also add to: +i18n_en.properties +i18n_de.properties +i18n_fr.properties +# ... all existing locale files +``` + +**Why**: Maintains consistency across languages and prevents missing translations. + +## 6. Security - Content Security Policy + +### Never Use Inline Scripts + +```html + + + + + +``` + +**All application logic must reside in dedicated JS/TS files** to comply with UI5's recommended CSP settings. + +## 7. TypeScript Event Handling (UI5 >= 1.115.0) + +### Use Control-Specific Event Types + +For **UI5 1.115.0 and above**, use typed event classes: + +```typescript +import { Button$PressEvent } from "sap/m/Button"; +import { Table$RowSelectionChangeEvent } from "sap/ui/table/Table"; + +export default class MainController extends Controller { + // ✅ CORRECT - Typed event + public onPress(event: Button$PressEvent): void { + const button = event.getSource(); // Correctly typed as Button + // ... + } + + public onRowSelectionChange(event: Table$RowSelectionChangeEvent): void { + const context = event.getParameter("rowContext"); // Typed parameter + // ... + } +} +``` + +### Fallback for UI5 < 1.115.0 + +```typescript +import Event from "sap/ui/base/Event"; + +public onPress(event: Event): void { + // Use generic Event type +} +``` + +**Event Type Pattern**: `{ControlName}${EventName}Event` +- Button press → `Button$PressEvent` +- Table selection → `Table$RowSelectionChangeEvent` +- Input change → `Input$ChangeEvent` + +## 8. MCP Tooling Integration + +### API Reference Lookup + +**ALWAYS** use the `get_api_reference` MCP tool for API documentation: + +```bash +# Get information on sap.m.Table +mcp get_api_reference sap.m.Table /path/to/project +``` + +This provides version-specific API documentation for your project's UI5 version. + +### Code Validation + +**ALWAYS** lint code before committing: + +```bash +# Run UI5 linter +mcp run_ui5_linter /path/to/project + +# Auto-fix issues (confirm with user first) +mcp run_ui5_linter /path/to/project --fix +``` + +Detects: +- Deprecated APIs +- Accessibility issues +- Best practice violations +- Security vulnerabilities + +### Local Development Server + +**CRITICAL**: UI5 CLI server does **NOT** serve default index files. + +```bash +# ❌ WRONG - Returns 404 +http://localhost:8080/ + +# ✅ CORRECT - Specify full path +http://localhost:8080/index.html +http://localhost:8080/test/testsuite.qunit.html +``` + +## 9. CAP Integration + +When creating UI5 projects **within a CAP project**: + +### Project Structure +``` +cap-project/ +├── app/ ← UI5 projects go here +│ ├── customers/ +│ └── orders/ +├── srv/ +├── db/ +└── package.json +``` + +### Setup Process + +1. **Create in `app/` directory** +```bash +cd app +yo @sap/fiori +``` + +2. **Install CAP Plugin** +```bash +# In CAP root directory +npm i -D cds-plugin-ui5 +``` + +3. **Get Service Information** +```bash +# List definitions +cds compile '*' + +# Get service endpoints +cds compile '*' --to serviceinfo +``` + +4. **Run from CAP Root** +```bash +# ❌ NEVER run ui5 serve in app subfolder +# ✅ ALWAYS run from CAP root +cds watch +``` + +**Why**: `cds watch` serves both backend and UI on the same origin (http://localhost:4004), eliminating proxy configuration needs. + +### No Proxy Needed + +**NEVER** configure `ui5-middleware-simpleproxy` in `ui5.yaml` for local CAP services: + +```yaml +# ❌ WRONG - Unnecessary proxy +server: + customMiddleware: + - name: ui5-middleware-simpleproxy + # Not needed for CAP! +``` + +`cds watch` handles routing automatically. + +## 10. Common Patterns + +### Getting Router +```javascript +this.getOwnerComponent().getRouter() +``` + +### Getting Model +```javascript +this.getView().getModel() // Default model +this.getView().getModel("i18n") // Named model +``` + +### Navigation +```javascript +this.getOwnerComponent().getRouter().navTo("detail", { + objectId: "123" +}); +``` + +### Creating Controls Programmatically +```javascript +import Button from "sap/m/Button"; +import MessageBox from "sap/m/MessageBox"; + +const oButton = new Button({ + text: "Click Me", + press: () => { + MessageBox.show("Hello World"); + } +}); +``` + +## 11.
