Nello's website was modernized to reflect the futuristic nature of their solution which allows you to remotely open the apartment doorway.

Nello provides a software with which a person can remotely open the apartment doorway – through an intercom system.
The user has an application on their phone that provides door access to their various service providers.
A handy app for people who spend the majority of their time outside of their apartment. It makes package delivery to a person's doorstep more secure.
Nello's website was modernized to reflect the futuristic nature of the device. Smart home devices are at the point, where they will soon be incorporated into almost every imaginable private environment. Just as life is no unimaginable without a smartphone.
The Nello website is a single page application. When a visitor is using a SPA, the page is not reloaded – only the view is being changed. This is relevant for the library the coders decided to use: ReactJS.
The coding team used ReactJS – a JavaScript library – to build the user interface and develop the Nello website.

ReactJS's popularity has increased as it is maintained by Instagram and Facebook, and has become a relatively universal and easy-to-use JavaScript library. Because the core fundamentals of this language are so simple, React is fast and easy to understand, in comparison with other JS libraries.
ReactJS's popular feature for creating web applications is that the data is loaded outside of the template (the look of the page), which gives you the possibility to manipulate the view without reloading the page.
With good reason, the library is being used by websites such as Netflix, Imgur, Feedly, Airbnb, and many others.

The client wanted to reflect the necessity of a smartphone device on their website. This was done by including an (artistic) scroll effect on the site: where a visitor can scroll through the entire content of the page through a realistically-depicted smartphone screen.
This "sticky" smartphone scroll effect conveys the functionality of the Nello app: operable directly on a person's mobile device.
