This master's thesis describes the development of the web application "Slatka Želja," designed for a craft business specialized in the production and sale of sweets. The application is a response to the needs of the modern market where time-constrained customers increasingly resort to online shopping. "Slatka Želja" allows for the ordering of personalized cakes and pastries, where customers can submit a picture of the desired product, create combinations of pastries by weight, and see a visual representation with details such as price and calorie count. Additionally, the application features a function to limit daily orders and set delivery dates to maintain high service quality. The application utilizes modern technology such as Visual Studio Code, MongoDB databases, and the Vue JavaScript framework, which provides flexibility, scalability, and interface interactivity. The goal of the application is to improve the craft business's operations by providing an efficient, easy-to-use digital platform that facilitates the ordering and sales process, and lays the groundwork for future development and expansion into new markets. With "Slatka Želja," the craft business not only enhances its competitiveness but also actively participates in digital transformation, opening up new opportunities for growth and adaptation in a dynamic business environment.
