5. Tech Stack

Project Technical Architecture

The new version has undergone a major refactoring of both the frontend and backend. The backend still uses the Gin Web framework, but the author has integrated the fx dependency injection framework, resulting in a very clean backend application structure that is particularly suitable for secondary development. In addition, MySQL has replaced leveldb for data storage. Since the system targets C-end users, many business data queries and statistics will be required in the future, and leveldb is no longer sufficient.

Gin + fx + MySQL

After version 3.0, API implementations in other languages, such as PHP and Java, will be added gradually. Considering the author's limited time and resources, the api directory has already been added. Interested contributors are welcome to claim and implement the language they are most familiar with.

The frontend framework remains:

Vue3 + Element-Plus

The page styles of both the frontend and backend have been completely redesigned, with almost all page styling code rewritten. The existing logic code has been retained, since the functionality has not changed significantly.

This refactoring and redesign was primarily intended to prepare for future feature expansion.
