Tech stack: Koa2 Node.js Sequelize Websocket, January 2022 - March 2022

A project from the Baidu Front-end Training Camp Advanced Class, with complete campus community functionality and a backend management system. Built with Koa2 + Sequelize, the backend of a powerful project!

1. Deployed the project to my own cloud server using PM2, configured Nginx reverse proxy to solve cross-origin issues, and set up error logging and log splitting.
2. Used Sequlize ORM for database operations and implemented user authentication and information encryption using JWT.
3. Used WebSocket to monitor the number of online users.

I was mainly responsible for the article management, section management, and system management interfaces. It was the first project I completed that was relatively complete~ Of course, it was also relatively immature at the time.

The development documentation for this project is also very detailed~ Because it was the first time I collaborated on a team project, I recorded the basic setup process.
