Q & A What are websocket? Why do we need it? Quoting from wikipedia , "WebSocket is a computer communications protocol, providing full-duplex communication channels over a single TCP connection. The WebSocket protocol was standardized by the IETF as RFC 6455 in 2011, and the WebSocket API in Web IDL is being standardized by the W3C." WebSockets are used for streaming messages. To implement real-time notification we need to stream messages from the server to the client without a refresh or making an HTTP request from the client. Hence websockets. How do we implement websockets in django? We will be using django-channels  (channels) for websockets. Django, by default does not support websocket. Channels is a django project which allows Django to handle websockets, HTTP and HTTP2 requests. But how does channels implement websockets in WSGI server (gunicorn) which does not support websockets. Simple we don't. Instead, we will be using  Daphne , an interface serv...

Notification System for GraphSpace Organization : National Resource for Network Biology (NRNB) GraphSpace is an user-friendly web-based platform that collaborating research groups can utilize for storage, interaction, and network sharing. A GraphSpace user can import graphs created in Cytoscape, upload them through a REST API, interact with them by customizing and saving layouts, share them within and between groups of collaborators, search for different graphs, and organize them using tags. These functions are enabled through GraphSpace’s comprehensive REST API, which allows users to communicate programmatically. Notifications are integral to all web applications as they are the means to tracking all important information. It is most optimal when a notification system is decoupled from the main application flow, because we can have a clear distinction between the utilities of the two applications. In this project, there are three primary types of notifications that need to...
