Since it is a stateful protocol, it will keep the client and server connected until one of them decides to cut it off. In contrast to HTTP, WebSocket is a bidirectional, full-duplex protocol. We can deal with this scenario with the aid of WebSockets. As a result, we require the client and server to maintain a permanent connection. But we can’t afford any delays while communicating in real-time. Since HTTP is a stateless protocol, a three-way handshake must be completed after each request, lengthening the time it takes to respond.
HTTP requestĭue to HTTP’s unidirectional nature, communication between the client and server is one-way only. After the data transfer is complete, the connection is terminated. The HTTP protocol is an application protocol that uses the TCP protocol to interconnect the client and server, which requires a three-way handshake. What is a WebSocket?Īn HTTP request, as we already know, is used to send any message or data from our client to a server. Furthermore, we will build a real-time messaging server using Node.js and the ws library. In this article, we will learn about real-time data transfer using WebSockets. But have you ever considered how these real-time apps are constructed? These have become a part of our everyday lives. Then add a new WebSocket route and use Hocuspocus' handleConnection() method to do the rest.We are all familiar with and frequently use real-time messaging applications that use WebSocket in Node js. To use Hocuspocus with Express, you need to use the express-ws package that adds WebSocket endpoints to Express applications.
When you don't call listen() on Hocuspocus, it will not start a WebSocket server itself but rather relies on you calling it's handleConnection() method manually. Hocuspocus can be used with any WebSocket implementation that uses ws under the hood. npx npx -port 8080 npx -webhook npx -sqlite #Express
Most likely you just want to run it with the npx command, although you can of course also install it globally or in your project with npm or yarn. Our CLI brings Hocuspocus to your command line in seconds. Maybe just to give it a try, or to test your webhooks locally. Sometimes, you just want to spin up a local Hocuspocus instance really fast.
