Fluence is an open application platform where apps can build on each other, share data and users. Fluence not only allows hosting services inside p2p network but also provides JS SDK for building web applications, which communicate with the services. After the introductory talk, we will dive right into something very practical. We will demonstrate the process of making a web application with Fluence JS SDK. We will start with an empty create-react-app project and work our way towards the fully functional solution. By the end of this talk, we will develop a text editor, which synchronizes it’s state and the user online status with collaborators over Fluence p2p network. The application will be interacting with two minimalistic services pre-deployed to Fluence: user-list and history, but all of the features will be implemented on client-side without any need to modify existing software. Expect a lot frontend and a lot of code in TypeScript!
