# Edison PowerPoint Add-in Developer Documentation
This document provides detailed technical information for developers working on the Edison PowerPoint Add-in.
## Architecture Overview
Edison is a PowerPoint add-in built with:
- **TypeScript** for type-safe code
- **React** for UI components
- **Office.js API** for PowerPoint integration
- **Fluent UI** for Microsoft-style interface components
The application follows a component-based architecture where each tool is encapsulated in its own React component.

## Development Environment Setup
### Prerequisites
- Node.js (LTS version recommended)
- npm
- Microsoft PowerPoint (desktop version)
### Setup Steps
1. Clone the repository:
```bash
git clone https://github.com/your-org/edison-powerpoint-addin.git
cd edison-powerpoint-addin
```
2. Install dependencies:
```bash
npm install
```
3. Build the project:
```bash
npm run build:dev
```
4. Start the development server:
```bash
npm run dev-server
```
5. Start the add-in in PowerPoint:
```bash
npm run start
```
### Local Development Certificates
Office Add-ins require HTTPS even for local development. The `office-addin-dev-certs` package is used to create and install self-signed certificates for development.
If you encounter certificate issues, run:
```bash
npx office-addin-dev-certs install
```
## Component Development Guidelines
### Creating a New Tool
1. Create a new component file in `src/taskpane/components/`
2. Import the necessary Office.js APIs and React hooks
3. Use the StatusContext for user feedback
4. Follow the pattern of existing components:
- Use the `PowerPoint.run()` method for PowerPoint operations
- Provide clear success/error messaging
- Handle selection states appropriately
Example component structure:
```tsx
import * as React from "react";
import { useState } from "react";
import { Button } from "@fluentui/react-components";
import { useStatusContext } from "./App";
const MyNewTool: React.FC = () => {
const { setStatusMessage, setStatusType, isProcessing, setIsProcessing } = useStatusContext();
const performAction = async () => {
setIsProcessing(true);
try {
await PowerPoint.run(async (context) => {
// Implement your PowerPoint operations here
await context.sync();
});
setStatusMessage("Operation completed successfully!");
setStatusType("success");
} catch (error) {
setStatusMessage(`Error: ${error.message}`);
setStatusType("error");
console.error("Operation error:", error);
} finally {
setIsProcessing(false);
}
};
return (
<Button onClick={performAction} disabled={isProcessing}>
My New Tool
</Button>
);
};
export default MyNewTool;
```
### Common PowerPoint.js Operations
#### Selecting Shapes
```typescript
const shapes = context.presentation.getSelectedShapes();
shapes.load("items");
await context.sync();
```
#### Working with Slide Masters
```typescript
const slideMasters = context.presentation.slideMasters;
slideMasters.load("items");
await context.sync();
```
#### Creating Shapes
```typescript
const shape = slide.shapes.addGeometricShape("Rectangle");
shape.left = 100;
shape.top = 100;
shape.height = 50;
shape.width = 50;
await context.sync();
```
## Status System
The application includes a status system that provides feedback to users:
- **Success**: Operation completed successfully
- **Warning**: Operation completed with concerns
- **Error**: Operation failed
- **Processing**: Shows a spinner while operations are in progress
Use the status context in your components:
```typescript
const {
statusMessage,
setStatusMessage,
statusType,
setStatusType,
isProcessing,
setIsProcessing
} = useStatusContext();
```
## Build and Deployment
### Development Build
```bash
npm run build:dev
```
### Production Build
```bash
npm run build
```
### Manifest Validation
```bash
npm run validate
```
This validates the manifest.xml file against the Office Add-in schema.
## Testing
Currently, the project doesn't have automated tests. This is an area for future improvement.
Recommended testing approach:
1. Manual testing in PowerPoint
2. Implementation of unit tests for individual utilities
3. Integration tests for PowerPoint API interactions
## Performance Considerations
- Minimize `context.sync()` calls, especially in loops
- Batch operations when possible
- Use memoization for expensive calculations
- Ensure proper cleanup of event listeners
## Common Issues and Solutions
### Add-in not loading in PowerPoint
- Verify the development server is running
- Check for certificate errors in the browser console
- Validate the manifest.xml file
### PowerPoint API errors
- Ensure correct API version is being used
- Check the sequence of operations (some operations require specific order)
- Verify selections exist before operating on them
## Best Practices
1. **Error Handling**: Always use try/catch blocks with PowerPoint API calls
2. **User Feedback**: Provide clear status messages for all operations
3. **Accessibility**: Ensure all UI elements have proper labels and keyboard access
4. **Theme Support**: Use Fluent UI theme tokens for consistent theming
5. **Code Organization**: Keep component files focused on a single responsibility
