Through observation of the lives of college students, it is found that many students tend to over-purchase items online, leading to the generation of idle items. Additionally, there are numerous second-hand trading groups in the friend circle, requiring participation in these groups for selling. Considering that people often use WeChat, the applet can provide a convenient trading platform, allowing idle items to be used by others without the need to download a separate app. In the development mode of WeChat applet, HTML, css, PHP, MySQL and other programming languages are used to realize the front-end interface display and interaction with the back-end database of the idle trading applet, meeting the basic requirements for selling on the WeChat platform. Keywords: WeChat applet, campus trading, idle items, second-hand trading.
