This program constructs a B2C e-commerce system connecting merchants to customers, utilizing the backend server framework MINA developed by the WeChat team. The MINA framework provides a comprehensive set of JavaScript APIs to the upper layer by encapsulating the WeChat client's capabilities, such as the file system, network connections, and task management. It is important to note that the front end of this program is developed using the highly efficient Vue framework and Element UI components. By establishing an online store, the program eliminates challenging operational tasks and reduces unnecessary expenses like commission fees on orders for merchants. Not only does it allow customers to place orders anytime and anywhere with ease, but it also facilitates online management for store owners.
