How arjunbaladarshan/2026_bewt_nest_crud-mysqldemo works
This is a NestJS student CRUD API backed by MySQL, with a small root greeting endpoint. The main workflow is an HTTP client calling the student controller, which delegates CRUD operations to a service that uses a TypeORM repository for student records. The root module configures MySQL from environment settings and registers the student feature. The README is the generic Nest starter README; architecture details here come from the sampled source, so no additional product capabilities are inferred.
Main entry points: student.controller.ts Student controller · app.module.ts Root module · student.service.ts Student service · app.controller.ts Root controller
