# @design.estate/dees-document
|
||
|
||
A versatile tool for dynamically generating and rendering business documents, such as invoices, using modern web technologies and elements.
|
||
|
||
## Install
|
||
|
||
To incorporate `@design.estate/dees-document` into your project, execute the following command in your terminal:
|
||
|
||
```shell
|
||
npm install @design.estate/dees-document --save
|
||
```
|
||
|
||
This command will install the package and add it to your project's dependencies, thus making all the necessary modules available within your `node_modules` directory.
|
||
|
||
## Usage
|
||
|
||
The `@design.estate/dees-document` package serves as a robust framework to facilitate the generation of business documents, such as invoices and contracts. Leveraging modern web technologies, this package integrates seamlessly with TypeScript and ES modules, offering a type-safe environment conducive to efficient, dynamic document creation. Presented here is a comprehensive guide to utilizing this package, ranging from initializing your environment to generating complete PDF documents.
|
||
|
||
### Getting Started
|
||
|
||
To embark on a document creation journey, initiate the document service. This service constitutes the core of this package and is typically started at the application's outset.
|
||
|
||
```typescript
|
||
import { PdfService, IPdfServiceConstructorOptions } from '@design.estate/dees-document';
|
||
|
||
async function setupPdfService() {
|
||
const options: IPdfServiceConstructorOptions = {
|
||
// configure your options here
|
||
};
|
||
|
||
const pdfService = await PdfService.createAndStart(options);
|
||
console.log('PDF Service started successfully.');
|
||
return pdfService;
|
||
}
|
||
```
|
||
|
||
The above code initializes the `PdfService`. Tailor the configuration options to suit your specific requirements.
|
||
|
||
### Creating Documents
|
||
|
||
With the PDF service initialized, you can now proceed to generate your documents. In the following section, you will find a detailed walkthrough for creating an invoice. This method can be adapted to other document types with necessary modifications.
|
||
|
||
#### Step-by-Step: Create an Invoice
|
||
|
||
1. **Define the Data Structure**: Construct the details of the invoice, including the sender, recipient information, and the details of the items being invoiced.
|
||
|
||
```typescript
|
||
import { ILetter } from '@design.estate/dees-document';
|
||
|
||
const invoiceData: ILetter = {
|
||
from: {
|
||
name: "Your Company Name",
|
||
address: {
|
||
streetName: "Your Street",
|
||
houseNumber: "123",
|
||
city: "Your City",
|
||
country: "Your Country",
|
||
postalCode: "12345",
|
||
},
|
||
email: "your-email@example.com",
|
||
phone: "123-456-7890",
|
||
},
|
||
to: {
|
||
name: "Recipient Company Name",
|
||
address: {
|
||
streetName: "Recipient Street",
|
||
houseNumber: "456",
|
||
city: "Recipient City",
|
||
country: "Recipient Country",
|
||
postalCode: "67890",
|
||
},
|
||
email: "recipient-email@example.com",
|
||
phone: "098-765-4321",
|
||
},
|
||
content: {
|
||
invoiceData: {
|
||
items: [
|
||
{
|
||
name: "Service or Product Name",
|
||
unitQuantity: 2,
|
||
unitNetPrice: 100.00,
|
||
unitType: 'service',
|
||
vatPercentage: 19,
|
||
currency: 'EUR',
|
||
}
|
||
]
|
||
}
|
||
},
|
||
subject: "Invoice for Services Rendered",
|
||
date: new Date().getTime(),
|
||
versionInfo: {
|
||
type: "final",
|
||
version: "1.0.0"
|
||
},
|
||
};
|
||
```
|
||
|
||
The `ILetter` interface captures all the components of an invoice, including both the sender (`from`) and recipient (`to`) information, alongside the details of the invoiced items.
|
||
|
||
2. **Generate the PDF**: Convert the invoice details into a PDF file.
|
||
|
||
```typescript
|
||
async function generateInvoice(pdfService: PdfService, invoiceData: ILetter) {
|
||
const pdfBuffer = await pdfService.createPdfFromLetterObject(invoiceData);
|
||
console.log('Invoice PDF generated successfully.');
|
||
|
||
// Here you could save the PDF to your filesystem, send it via email, etc.
|
||
}
|
||
```
|
||
|
||
The `createPdfFromLetterObject` function returns a `Buffer` that contains the generated PDF, enabling you to save it to a file, send it to clients, or store it for record-keeping.
|
||
|
||
3. **Integrate It All**: The following script ties together the PDF service and generates the invoice with the described data.
|
||
|
||
```typescript
|
||
async function main() {
|
||
const pdfService = await setupPdfService();
|
||
await generateInvoice(pdfService, invoiceData);
|
||
}
|
||
|
||
main().then(() => console.log('Invoice generation process completed.'));
|
||
```
|
||
|
||
This example initiates the PDF service and utilizes it to generate a PDF invoice with specified parameters.
|
||
|
||
### Advanced Document Features
|
||
|
||
The package is designed to create a broad range of documents, far beyond simple invoices. Utilize the modular architecture to customize documents to your specific business requirements.
|
||
|
||
#### Advanced Scenarios
|
||
|
||
1. **Custom Styling**: Alter the visual styles of various elements within your documents, like headers, footers, and more through CSS or inline styles.
|
||
|
||
```typescript
|
||
import { DeDocumentViewer } from '@design.estate/dees-element';
|
||
|
||
const customStyledViewer = new DeDocumentViewer();
|
||
customStyledViewer.style.setProperty('--main-bg-color', 'lightblue');
|
||
document.body.appendChild(customStyledViewer);
|
||
```
|
||
|
||
Adjust styles either with standard CSS or via dynamic TypeScript changes.
|
||
|
||
2. **Interactive Document Elements**: Integrate interactive UI components, like buttons or input fields, fitting seamlessly into your documents.
|
||
|
||
3. **Multi-page Document Generation**: Handle content overflow elegantly through automatic page creation, keeping headers and footers intact.
|
||
|
||
```typescript
|
||
pdfService.adjustDePageScaling();
|
||
```
|
||
|
||
Adapt between print and digital formats, managing scaling effectively.
|
||
|
||
4. **Embedding Images and Logos**: Enhance your document's appearance with company logos, graphics, and other auxiliary content.
|
||
|
||
### Additional Capabilities

||
|
||
Beyond basic functionality, this package offers a range of advanced features:
|
||
|
||
- **Document Management**: Manage multiple document templates, maintain version control, and append annotations or notes.
|
||
- **Dynamic Rendering**: Utilize templating engines to render dynamic content based on input variables.
|
||
- **Responsive Design for Digital Documents**: Ensure your documents are consistently displayed across various devices.
|
||
|
||
