protoc-gen-persist

protoc-gen-persist

Protobuf plugin that generate a persistence layer backed by SQL or Spanner database

Rationale

An opinionated protoc plugin that will help generate boiler plate go code for GRPC micro services projects that need to interact with a SQL or Spanner database. The code generation is accomplished by providing a protobuf file with proper annotations, and then running the protoc cli tool with the --go_out option, and the --persist_out options set to the same directory.

Installation

This project requires protoc and protoc-gen-go be installed

Then install with go get github.com/tcncloud/protoc-gen-persist

Documentation

documentation for the project can be found Here The documentation goes over the persist options, how to structure your proto file, custom type mapping to/from the database, and spanner query parsing

NOTE: This project is under development, use it at your own risk!
