WebSocket is the internet protocol that allows for full duplex communication between a server and clients. This protocol goes beyond the typical HTTP request/response paradigm; with WebSockets, the server may send data to a client without the client initiating a request, thus allowing for some very interesting applications. WebSocket is the internet protocol that allows for full duplex communication between a server and clients. This protocol goes beyond the typical HTTP request/response paradigm; with WebSockets, the server may send data to a client without the client initiating a request, thus allowing for some very interesting applications. For example, the client data would be accessed by calling a "list_clients()" function instead of making an SQL query directly against the client table on the database. This allows the underlying database to be replaced without making any change to the other tiers. There are some who view a web application as a two-tier architecture. If a ping message is not answered by a pong message from the peer, the WebSocket is assumed disconnected and the connection is closed with a WebSocketStatus.GOING_AWAY close code. When a ping signal is sent, the pong message must be received within pingInterval . Creating a Web App From Scratch Using Python Flask and MySQL: Part 2 In this series, we'll be using Python , Flask and MySQL to create a simple web application from scratch. It will be a simple bucket list application where users can register, sign in and create their bucket list. A sample appears on the left and the output appears on the right. If you’ve played with DartPad before, you can click New Pad to get back to the original sample. Click Run. The sample runs again, updating the output. Choose an HTML sample like Sunflower, using the Samples list at the upper right. Again, the output appears to the right. ServiceStack is an outstanding tool belt to create such a system in a frictionless manner, especially sophisticated designed and fun to use.
