# @design.estate/dees-document
|
|
|
|
A comprehensive tool for dynamically generating and rendering business documents like invoices using modern web technologies.
|
|
|
|
## 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, contracts, and reports. Leveraging modern web technologies, this package integrates seamlessly with TypeScript and ES modules, offering a type-safe environment conducive to efficient, dynamic document creation.
|
|
|
|
Below, we provide a detailed guide for utilizing this package, from initializing your environment to generating complete PDF documents.
|
|
|
|
### Setting Up the Environment
|
|
|
|
Before diving into document creation, ensure your environment is properly configured. Make sure to import necessary dependencies and setup configurations:
|
|
|
|
```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;
|
|
}
|
|
```
|
|
|
|
In this setup snippet, you set up the `PdfService` which is the core component for PDF generation. The configuration options should be adjusted to fit your needs, especially considering options such as file paths, languages, and template directories.
|
|
|
|
### Creating a Document Template
|
|
|
|
To create documents, particularly invoices, you'll first need to define a template. This template describes the structure of your document:
|
|
|
|
```typescript
|
|
import { ILetter } from '@design.estate/dees-document';
|
|
|
|
const invoiceTemplate: 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: 100.0,
|
|
unitType: 'service',
|
|
vatPercentage: 19,
|
|
currency: 'EUR',
|
|
},
|
|
],
|
|
},
|
|
},
|
|
subject: 'Invoice for Services Rendered',
|
|
date: new Date().getTime(),
|
|
versionInfo: {
|
|
type: 'final',
|
|
version: '1.0.0',
|
|
},
|
|
};
|
|
```
|
|
|
|
The `invoiceTemplate` object utilizes the `ILetter` interface which specifies the structure for invoice data, including sender and recipient details, itemization, and pricing.
|
|
|
|
### Generating the Document
|
|
|
|
Once a template is established, the next step is generating a PDF:
|
|
|
|
```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.
|
|
}
|
|
```
|
|
|
|
In this function, the `createPdfFromLetterObject` method converts your invoice data into a `Buffer` containing the PDF. This `Buffer` can subsequently be saved as a file or sent over HTTP.
|
|
|
|
### Comprehensive Example
|
|
|
|
Below is an example integrating all previous steps into a single coherent script:
|
|
|
|
```typescript
|
|
async function main() {
|
|
const pdfService = await setupPdfService();
|
|
const invoiceData: ILetter = {
|
|
// Populate your invoice object
|
|
};
|
|
await generateInvoice(pdfService, invoiceData);
|
|
}
|
|
|
|
main().then(() => console.log('Invoice generation process completed.'));
|
|
```
|
|
|
|
This script encompasses initializing services and generating a PDF in a streamlined, efficient workflow.
|
|
|
