Using MCP Tools (New in v2.0.0)

This skill integrates with the official @ui5/mcp-server for live development tools:

  • Scaffolding: Create projects with ui5-app-scaffolder agent or /ui5-scaffold command
  • API Reference: Lookup controls with ui5-api-explorer agent or /ui5-api command
  • Code Quality: Run linter with ui5-code-quality-advisor agent or /ui5-lint command
  • Migration: Upgrade versions with ui5-migration-specialist agent
  • Version Info: Check releases with /ui5-version command
  • Tool Catalog: List all MCP tools with /ui5-mcp-tools command

For setup and troubleshooting, see references/mcp-integration.md.

Graceful Fallback: All features work without MCP by using reference files and built-in templates.

Quick Start

Creating a Basic SAPUI5 App

Use UI5 Tooling (recommended) or SAP Business Application Studio:

# Install UI5 CLI
npm install -g @ui5/cli

# Create new project
mkdir my-sapui5-app && cd my-sapui5-app
npm init -y

# Initialize UI5 project
ui5 init

# Add UI5 dependencies
npm install --save-dev @ui5/cli

# Start development server
ui5 serve

Project Structure:

my-sapui5-app/
├── webapp/
│   ├── Component.js
│   ├── manifest.json
│   ├── index.html
│   ├── controller/
│   │   └── Main.controller.js
│   ├── view/
│   │   └── Main.view.xml
│   ├── model/
│   │   └── formatter.js
│   ├── i18n/
│   │   └── i18n.properties
│   ├── css/
│   │   └── style.css
│   └── test/
│       ├── unit/
│       └── integration/
├── ui5.yaml
└── package.json

Templates Available:

  • templates/basic-component.js: Component template
  • templates/manifest.json: Application descriptor template
  • templates/xml-view.xml: XML view with common patterns
  • templates/controller.js: Controller with best practices
  • templates/formatter.js: Common formatter functions

Use templates by copying to your project and replacing placeholders ({{namespace}}, {{ControllerName}}, etc.).

Core Concepts

1. MVC Architecture

  • Model: Data layer (JSON, OData, XML, Resource models)
  • View: Presentation layer (XML, JavaScript, JSON, HTML)
  • Controller: Business logic layer
  • Binding: Synchronizes model and view (One-way, Two-way, One-time)

Reference: references/core-architecture.md for detailed architecture concepts.

2. Component & Manifest

  • Component.js: Entry point, initializes router and models
  • manifest.json: Central configuration (models, routing, dependencies, data sources)

Key manifest sections:

  • sap.app: Application metadata and data sources
  • sap.ui: UI technology and device types
  • sap.ui5: UI5-specific configuration (models, routing, dependencies)

3. Data Models

JSON Model (client-side):

var oModel = new JSONModel({
    products: [...]
});
this.getView().setModel(oModel);

OData V2 Model (server-side):

"": {
    "dataSource": "mainService",
    "settings": {
        "defaultBindingMode": "TwoWay",
        "useBatch": true
    }
}

Resource Model (i18n):

"i18n": {
    "type": "sap.ui.model.resource.ResourceModel",
    "settings": {
        "bundleName": "my.app.i18n.i18n"
    }
}

Reference: references/data-binding-models.md for comprehensive guide.

4. Views & Controllers

XML View (recommended):

<mvc:View
    controllerName="my.app.controller.Main"
    xmlns="sap.m"
    xmlns:mvc="sap.ui.core.mvc">
    <Page title="{i18n>title}">
        <List items="{/products}">
            <StandardListItem title="{name}" description="{price}"/>
        </List>
    </Page>
</mvc:View>

5. Routing & Navigation

Navigate programmatically:

this.getOwnerComponent().getRouter().navTo("detail", {
    objectId: sId
});

Reference: references/routing-navigation.md for routing patterns.

SAP Fiori Elements

Build applications without JavaScript UI code using OData annotations.

Application Types

  1. List Report: Searchable, filterable tables/charts
  2. Object Page: Detailed view with sections and facets
  3. Analytical List Page: Visual filters and analytics
  4. Overview Page: Card-based dashboards
  5. Worklist: Simplified list for tasks

Quick Setup

manifest.json for List Report + Object Page:

{
    "sap.ui5": {
        "dependencies": {
            "libs": {
                "sap.fe.templates": {}
            }
        },
        "routing": {
            "targets": {
                "ProductsList": {
                    "type": "Component",
                    "name": "sap.fe.templates.ListReport",
                    "options": {
                        "settings": {
                            "contextPath": "/Products",
                            "variantManagement": "Page"
                        }
                    }
                }
            }
        }
    }
}

Key Annotations:

  • @UI.LineItem: Table columns
  • @UI.SelectionFields: Filter bar fields
  • @UI.HeaderInfo: Object page header
  • @UI.Facets: Object page sections

Reference: references/fiori-elements.md for comprehensive guide.

Metadata-Driven Controls (MDC)

The sap.ui.mdc library provides metadata-driven controls for building dynamic UIs at runtime.

Key Controls

  • MDC Table: Data display with dynamic columns based on metadata
  • MDC FilterBar: Complex filter conditions with PropertyInfo
  • MDC Value Help: Assisted data input with suggestions

Quick Example

<mdc:Table
    id="mdcTable"
    delegate='{name: "my/app/delegate/TableDelegate", payload: {}}'
    p13nMode="Sort,Filter,Column"
    type="ResponsiveTable">
    <mdc:columns>
        <mdcTable:Column propertyKey="name" header="Name">
            <Text text="{name}"/>
        </mdcTable:Column>
    </mdc:columns>
</mdc:Table>

Reference: references/mdc-typescript-advanced.md for comprehensive MDC guide with TypeScript.

Testing

Unit Tests (QUnit)

Test individual functions and modules:

QUnit.module("Formatter Tests");
QUnit.test("Should format price correctly", function(assert) {
    var fPrice = 123.456;
    var sResult = formatter.formatPrice(fPrice);
    assert.strictEqual(sResult, "123.46 EUR", "Price formatted");
});

Integration Tests (OPA5)

Test user interactions and flows:

opaTest("Should navigate to detail page", function(Given, When, Then) {
    Given.iStartMyApp();
    When.onTheWorklistPage.iPressOnTheFirstListItem();
    Then.onTheObjectPage.iShouldSeeTheObjectPage();
    Then.iTeardownMyApp();
});

Mock Server

Simulate OData backend:

var oMockServer = new MockServer({
    rootUri: "/sap/opu/odata/sap/SERVICE_SRV/"
});
oMockServer.simulate("localService/metadata.xml", {
    sMockdataBaseUrl: "localService/mockdata"
});
oMockServer.start();

Reference: references/testing.md for comprehensive testing guide.

Best Practices

  1. Always Use Async - sap.ui.define, async:true in manifests
  2. Use XML Views - declarative and tooling-friendly
  3. Proper Namespacing - com.mycompany.myapp.controller.Main
  4. Internationalization - always use i18n for texts
  5. Data Binding Over Manual Updates - automatic XSS protection
  6. Security - enable CSP, validate input, use HTTPS
  7. Performance - component preload, lazy loading, batch requests
  8. Accessibility - semantic controls, labels, keyboard navigation

Common Patterns

CRUD Operations

// Create
oModel.create("/Products", oData, {success: function() {MessageToast.show("Created");}});

// Read
oModel.read("/Products", {filters: [new Filter("Price", FilterOperator.GT, 100)]});

// Update
oModel.update("/Products(1)", {Price: 200}, {success: function() {MessageToast.show("Updated");}});

// Delete
oModel.remove("/Products(1)", {success: function() {MessageToast.show("Deleted");}});

Filtering & Sorting

var oBinding = this.byId("table").getBinding("items");
oBinding.filter([new Filter("price", FilterOperator.GT, 100)]);
oBinding.sort([new Sorter("name", false)]);

Dialog Handling

if (!this.pDialog) {
    this.pDialog = this.loadFragment({
        name: "my.app.view.fragments.MyDialog"
    });
}
this.pDialog.then(function(oDialog) {oDialog.open();});

Troubleshooting Common Issues

Binding not working

  1. Check model set on view/component
  2. Verify correct binding path
  3. Confirm data loaded
  4. Debug: console.log(this.getView().getModel().getData())

OData call failing

  1. Verify service URL in manifest.json
  2. Check CORS configuration
  3. Test authentication
  4. Use browser Network tab

View not displaying

  1. Check view registration in manifest.json
  2. Verify routing configuration
  3. Match controller name
  4. Check browser console for errors

Performance problems

  1. Enable component preload
  2. Use growing lists for large datasets
  3. Implement OData paging
  4. Use one-way binding when possible
