Repogen is a code generator for database repository in Golang. (WIP)
|
||||
Repogen is a code generator for database repository in Golang inspired by Spring Data JPA. (WIP)
|
||||
|
||||
## Features
|
||||
|
||||
Repogen is a library that generates MongoDB repository implementation from repository interface by using method name pattern.
|
||||
|
||||
- Method signature validation
|
||||
- Supports single-entity and multiple-entity operations
|
||||
- Supports many comparison operators
