uJoin is a social network developed by a Fribourg start-up aiming to connect people through real-life activities. uJoiners (members of the community) fill in their hobbies, and relevant activities are brought to them so they can take part to fun events and meet people they share common tastes with. The goal of this project is to create a JavaScript SDK to provide developers with a simple and elegant way to handle the communication with uJoin API.
