What’s New in Version 2.0 (Major Upgrade)

Version 2.0 represents a massive architectural leap forward, embracing the absolute latest standards in modern web development to deliver unmatched performance and developer experience:

• Angular 21 Core: Upgraded to the latest Angular framework for lightning-fast performance, strict type safety, and future-proof stability.
• Zoneless Change Detection: Operates entirely without Zone.js, utilizing Angular’s latest zoneless capabilities for optimal runtime efficiency and lower memory usage.
• Reactive Signals: State management has been completely rewritten using Angular Signals and computed properties for immediate, glitch-free UI updates across the editor and preview panes.
• Standalone Components: Zero NgModules. The entire application uses a modern, streamlined standalone component architecture making it easier to read and extend.
• Native Control Flow: Utilizing the new built-in template syntax (@if, @for) for cleaner, faster DOM rendering.

Key Features

• Live PDF Preview: See your invoice update in real-time as you type. What you see on the screen is exactly what gets exported.
• Smart Calculations: Automatically computes line item totals, applies configurable tax percentages, and updates the grand total instantly.
• High-Quality PDF Export: One-click export to A4 PDF format utilizing lazy-loaded html2pdf.js and html2canvas for crisp, professional documents.
• Multi-Currency Support: Switch seamlessly between major currencies (USD, EUR, GBP, INR, AUD, CAD). Adding your own custom currencies takes just one line of code.
• Company Branding: Upload a custom company logo (stored efficiently as Base64) and add personalized business details to your headers.
• Authorized Signatures: Support for digital sign-offs with an authorized name field and an optional signature image upload.
• Print-Ready Styles: Optimized print CSS means users can print directly from the browser with a perfect layout, hiding all editor UI elements automatically.
• Zero Data Loss: Built-in auto-save functionality powered by the native LocalStorage API.
• Fully Responsive: A clean, dual-pane editor on desktop that elegantly collapses into a mobile-friendly view with a toggleable sidebar.

Technology Stack & Deployment

Built with Angular 21 (TypeScript), Custom SCSS, html2pdf.js, and the browser’s LocalStorage API. Because this is a 100% static frontend application, you can host it anywhere for pennies or entirely for free via drag-and-drop or Git CI/CD on platforms like Netlify, Vercel, GitHub Pages, Firebase Hosting, AWS S3, and DigitalOcean.
