Video streaming sites have been the cornerstone of contemporary digital media, changing the way content is consumed by end-users. This thesis describes the development and architecture of a video-sharing website modelled after industry giants such as YouTube. The development lifecycle involves extensive research into current offerings, systematic analysis of requirements, and the design of a scalable MongoDB data architecture. Implementation employs a sound technology stack, with backend services utilizing Node.js and frontend interactivity with React, to provide fundamental features such as video uploading, real-time streaming, user interaction features such as likes and comments, and authentication security. Extensive testing protocols were followed before the system deployment on a cloud-based host. This project not only showcases the hands-on application of full-stack web technology, but it goes further into detailing the developmental challenges overcome, making it a stepping-stone into future innovations in video-sharing applications.
