$ show feihua/zero-admin
This is a large, scaffolded e-commerce backend system built with the go-zero microservice framework. It implements a full suite of admin and frontend APIs for managing products, orders, members, coupons, content, and system settings. The architecture is microservices-based with separate RPC services for each domain (sys, cms, oms, pms, sms, ums) plus search, consumer, and job services. The codebase is heavily generated using goctl and gorm.io/gen, resulting in a high volume of boilerplate CRUD logic files—many of which are still stubs containing only 'todo: add your logic here' comments. While the system demonstrates a consistent pattern for service decomposition and provides reusable utility packages (pkg/errorx, pkg/time_util, pkg/mq), the majority of business logic is incomplete, and there are signs of technical drift such as duplicate JWT library usage, mixed ORM approaches, and hardcoded configuration values. The project is actively maintained but still in a work-in-progress state, with the README warning of significant backend changes and incomplete frontend adaptation.
The LLM identified 3 files worth highlighting for reuse:
Provides a clean, reusable abstraction over RabbitMQ with simple publish, consume, and delayed message sending. It handles connection reuse, exchange/queue binding, and supports both simple and delayed delivery (via RabbitMQ plugin). The code is well-structured, isolates the MQ implementation, and can be extracted into other projects with minimal changes.
A small, focused utility for converting between Go's time.Time and common string formats (e.g., '2006-01-02 15:04:05'). It handles nil pointers, provides default values, and has a clean API. This is a textbook example of a reusable helper that can be dropped into any Go project dealing with time formatting.
Implements Elasticsearch search with multi-field matching, filtering, highlighting, and pagination. The logic constructs a compound query using bool query with must, filter, and should clauses. It handles empty results gracefully and returns a structured response. This is a well-implemented search pattern that can be adapted for other domains.
