Overview of the System
The Legal Document Generator is designed with two main components:
- Backend: Built with ASP.NET Core Web API for generating documents (PDF/DOCX).
- Frontend: An interactive Angular-based interface for user input and interactions.
Technologies Involved
The application uses the following technologies:
- Backend: ASP.NET Core Web API, iTextSharp, and Open XML SDK.
- Frontend: Angular with Bootstrap for responsive design.
- Optional: Database (e.g., SQL Server) for storing templates or user data.
Backend Implementation
Step 1: Create the API Project
Use the following commands to create an ASP.NET Core Web API project:
dotnet new webapi -n LegalDocumentGeneratorAPI
cd LegalDocumentGeneratorAPIStep 2: Install Necessary Libraries
Install iTextSharp and Open XML SDK for document generation:
dotnet add package iTextSharp --version 5.5.13.1
dotnet add package DocumentFormat.OpenXml --version 2.10.0Step 3: Create the Document Generation Service
Below is a sample code snippet for generating a PDF:
public class DocumentGeneratorService {
public byte[] CreatePdf(string title, string content) {
using (MemoryStream memoryStream = new MemoryStream()) {
Document document = new Document();
PdfWriter writer = PdfWriter.GetInstance(document, memoryStream);
document.Open();
document.Add(new Paragraph(title));
document.Add(new Paragraph(content));
document.Close();
return memoryStream.ToArray();
}
}
}Frontend Implementation
Step 1: Set Up the Angular Project
Run the following command to create a new Angular project:
ng new legal-document-generator
cd legal-document-generatorStep 2: Create a Service
Use Angular's HttpClientModule to communicate with the backend API:
generatePdf(title: string, content: string): Observable<Blob> {
return this.http.post(`${this.apiUrl}/generate-pdf`, { title, content }, { responseType: 'blob' });
}Step 3: Build the User Interface
Create a form for user inputs:
<form>
<div>
<label>Title:</label>
<input type="text" [(ngModel)]="title" required />
</div>
<div>
<label>Content:</label>
<textarea [(ngModel)]="content" required></textarea>
</div>
<button (click)="generatePdf()">Generate PDF</button>
</form>Deployment and Testing
- Host the API on Azure or AWS.
- Deploy the Angular app to Firebase, Netlify, or AWS S3.
Optional Features
- Template Management
- User Authentication
- Cloud Storage Integration
