# RPC Examples
|
||
|
||
This directory contains complete examples for all `goctl rpc` code generation scenarios.
|
||
|
||
Each example includes:
|
||
- `.proto` source files
|
||
- `README.md` (English) and `README-cn.md` (中文) documentation
|
||
|
||
## Examples

|
||
|
||
## Prerequisites
|
||
|
||
- [Go](https://go.dev/) 1.22+
|
||
- [protoc](https://github.com/protocolbuffers/protobuf/releases) (Protocol Buffers compiler)
|
||
- [protoc-gen-go](https://pkg.go.dev/google.golang.org/protobuf/cmd/protoc-gen-go) and [protoc-gen-go-grpc](https://pkg.go.dev/google.golang.org/grpc/cmd/protoc-gen-go-grpc)
|
||
- [goctl](https://github.com/zeromicro/go-zero/tree/master/tools/goctl)
|
||
|
||
## Quick Start
|
||
|
||
```bash
|
||
# Install protoc plugins
|
||
go install google.golang.org/protobuf/cmd/protoc-gen-go@latest
|
||
go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@latest
|
||
|
||
# Try the basic example
|
||
cd 01-basic
|
||
mkdir -p output && cd output && go mod init example.com/demo && cd ..
|
||
goctl rpc protoc greeter.proto \
|
||
--go_out=output --go-grpc_out=output --zrpc_out=output \
|
||
--go_opt=module=example.com/demo --go-grpc_opt=module=example.com/demo \
|
||
--module=example.com/demo -I .
|
||
```

||
cd 01-basic
|
||
mkdir -p output && cd output && go mod init example.com/demo && cd ..
|
||
goctl rpc protoc greeter.proto \
