Guojiang Shop

Guojiang, also called Jam Shop, is a free open-source eCommerce solution written in PHP on the Laravel framework. It is modular, extensible and designed to fit most mainstream domestic Chinese B2C shopping scenarios, with a WeChat mini-program as the customer-facing storefront.

The project provides only an API and a back-end admin panel, not a desktop web shop; teams that need one can build it on the same architecture. It uses Laravel with dingo/api for the interfaces, Laravel-admin for the management site, and a module or package approach in which each module is a reusable package with unit tests for the base modules. The mini-program source lives in a separate repository.

The README says it can be adapted from B2C to B2B, O2O or S2B2C models. Complete API documentation, a usage tutorial, business documentation and design files are provided. Guojiang is MIT licensed and mostly documented in Chinese.
