Django is a web application framework written in Python that emphasizes rapid development and clean methods. Although Django is a web framework, to answer the question whether Django is a front-end or a back-end, you need to have a deep understanding of the concepts of front-end and back-end. The front end refers to the interface that users directly interact with, and the back end refers to server-side programs. They interact with data through the HTTP protocol. When the front-end and back-end are separated, the front-end and back-end programs can be developed independently to implement business logic and interactive effects respectively, and data exchange.

As a C# developer, our development work usually includes front-end and back-end development. As technology develops and the complexity of projects increases, the collaborative development of front-end and back-end has become more and more important and complex. This article will share some front-end and back-end collaborative development techniques to help C# developers complete development work more efficiently. After determining the interface specifications, collaborative development of the front-end and back-end is inseparable from the interaction of API interfaces. To ensure the smooth progress of front-end and back-end collaborative development, the most important thing is to define good interface specifications. Interface specification involves the name of the interface

As a fast and efficient programming language, Go language is widely popular in the field of back-end development. However, few people associate Go language with front-end development. In fact, using Go language for front-end development can not only improve efficiency, but also bring new horizons to developers. This article will explore the possibility of using the Go language for front-end development and provide specific code examples to help readers better understand this area. In traditional front-end development, JavaScript, HTML, and CSS are often used to build user interfaces

Methods for implementing instant messaging include WebSocket, Long Polling, Server-Sent Events, WebRTC, etc. Detailed introduction: 1. WebSocket, which can establish a persistent connection between the client and the server to achieve real-time two-way communication. The front end can use the WebSocket API to create a WebSocket connection and achieve instant messaging by sending and receiving messages; 2. Long Polling, a technology that simulates real-time communication, etc.
