Key API Namespaces

Context APIs

The `Context` object provides access to all framework capabilities and is passed to your component's lifecycle methods. It contains:

- **Client**: Information about the client (form factor, network status)

- **Device**: Device capabilities (camera, location, microphone)

- **Factory**: Factory methods for creating framework objects

- **Formatting**: Number and date formatting

- **Mode**: Component mode and tracking

- **Navigation**: Navigation methods

- **Resources**: Access to resources (images, strings)

- **UserSettings**: User settings (locale, number format, security roles)

- **Utils**: Utility methods (getEntityMetadata, hasEntityPrivilege, lookupObjects)

- **WebApi**: Dataverse Web API methods

Data APIs

- **DataSet**: Work with tabular data

- **Column**: Access column metadata and data

- **Entity**: Access record data

- **Filtering**: Define data filtering

- **Linking**: Define relationships

- **Paging**: Handle data pagination

- **SortStatus**: Manage sorting

UI APIs

- **Popup**: Create popup dialogs

- **PopupService**: Manage popup lifecycle

- **Mode**: Get component rendering mode

Metadata APIs

- **AttributeMetadata**: Column metadata (model-driven only)

- **PropertyHelper**: Property metadata helpers

Standard Control

- **StandardControl**: Base interface for all code components with lifecycle methods:

- `init()`: Initialize component

- `updateView()`: Update component UI

- `destroy()`: Cleanup resources

- `getOutputs()`: Return output values

Usage Guidelines

Model-Driven vs Canvas Apps

Some APIs are only available in model-driven apps due to platform differences:

- **AttributeMetadata**: Model-driven only - provides detailed column metadata

- Most other APIs are available in both platforms

API Version Compatibility

- Always check the API availability for your target platform (model-driven or canvas)

- Some APIs may have different behaviors across platforms

- Test components in the target environment to ensure compatibility

Common Patterns

1. **Accessing Context APIs**

```typescript

// In init or updateView

const userLocale = context.userSettings.locale;

const isOffline = context.client.isOffline();

```

2. **Working with DataSet**

```typescript

// Access dataset records

const records = context.parameters.dataset.records;

// Get sorted columns

const sortedColumns = context.parameters.dataset.sorting;

```

3. **Using WebApi**

```typescript

// Retrieve records

context.webAPI.retrieveMultipleRecords("account", "?$select=name");

// Create record

context.webAPI.createRecord("contact", data);

```

4. **Device Capabilities**

```typescript

// Capture
