High-performance web server based on Reactor


A high-performance web server based on the multiplexed Reactor pattern, the underlying implementation uses the epoll model.

I will continue to update this project, continue to improve the backend and frontend issues, and create a complete project. So far, the project has completed the most basic back-end construction and simple front-end construction.

This is the v2.0 version. Here, in April 2024, I remade this project and the code was optimized to a certain extent.

Older versions can be found in Release: v1.0

Among them, the basic principles of epoll in this project and the basic principles of multiplexing high-performance IO can be seen in my other repo https://github.com/Yufccode/Multiplexing-high-performance-IO-server

Overall structure of Reactor server

Project details

Two servers are implemented in the project.

epoll_server

By encapsulating the epoll feature of Linux, an epoll-based network server is implemented. This network server does not have any encapsulation and can be tested through telnet.

Implementation details and code explanations can be found at: work_epoll.md

reactor_server

On the basis of multi-channel transfer, the server is further encapsulated and the dispatch feature is added to realize the reactor mode web server.

  • The backend adopts epoll's multi-pass listening mode
  • Encapsulation using reactor mode
  • Added web server function, which can analyze http requests and build http responses
  • Add a simple front-end page as a test

Implementation details and code explanations can be found at: work_reactor.md

Introduction to project principles

This project is based on Socker programming and uses epoll-style multi-way transfer to build a Reactor mode network server.

This project is actually the core of the Nginx server.
