FAQ

Custom front-end development focuses on building user interfaces tailored to your unique business requirements. This approach ensures optimal performance, seamless user experiences, and compatibility across all devices and browsers. In a highly competitive market, a modern and responsive front-end is crucial for improving user engagement and satisfaction, giving your business a competitive edge.

Micro front-end development breaks down complex applications into smaller, independently deployable components, enabling parallel development and faster time-to-market. This approach fosters greater scalability and allows for more robust applications by diversifying development across multiple teams. Each team can focus on specific features independently, resulting in easier maintenance and the ability to implement updates without affecting the entire application.

Ensuring front-end quality across various browsers and devices requires a rigorous approach, including comprehensive testing on major browsers like Chrome, Firefox, Safari, and Edge and different devices such as desktops, tablets, and mobile phones. For instance, at N-iX, by incorporating automated testing, we streamline the process, reduce regression testing costs, and ensure consistent performance and a seamless user experience across all platforms.

Progressive Web Apps (PWAs) work offline, load quickly, and provide a native app-like experience without the need for app store downloads, making them an excellent choice for businesses seeking high performance and accessibility across devices. Native apps, at the same time, remain the preferred choice for applications requiring deep integration with device hardware or high-performance requirements.

Yes, a front-end web application can be migrated to a desktop application using frameworks like Electron. Electron allows developers to create cross-platform desktop applications using web technologies such as HTML, CSS, and JavaScript. With Electron, your web app can be packaged as a standalone desktop application for Windows, macOS, and Linux, while retaining the same functionality and user experience.
