frpc

An rpc code generation framework for c++, It supports c++17/20/23

Support this repository:

• ⭐ Star the project: Star this. It means a lot to me! 💕

Quick Start 🚀

• need install uuid msgpack xmake, >= gcc version 13.1.0 (GCC)

1. compile frpc

git clone https://github.com/fantasy-peak/frpc.git
cd frpc
xmake build -v -y --file=./xmake.lua
xmake install -o . --file=./xmake.lua

2. define protocol

protocol example.

3. generate code

./bin/frpc -f ./config/config.yaml -t ./template/cpp -o ./out -w ./template/web --auto_sort=1 --debug=0

4. compile test example

xmake build -v -y --file=./test_xmake.lua
xmake install -o . --file=./test_xmake.lua
./bin/coro_frpc_bi

Docker compilation environment

git clone https://github.com/fantasy-peak/frpc.git
cd frpc && cd docker && make

Type Mapping

frpc type	c++ type	frpc type	c++ type
bool	bool	f64	double
i8	int8_t	f32	float
u8	uint8_t	vector	std::vector
i16	int16_t	option	std::optional
u16	uint16_t	string	std::string
i32	int32_t	map	std::unordered_map
u32	uint32_t	DateTime	frpc::DateTime
i64	int64_t	Date	frpc::Date
u64	uint64_t	Time	frpc::Time

Protocol Definition

It uses yaml to define interface data, Then generate a header file library.

property:
  filename: frpc.hpp  # Generate the name of the header file library
  namespace: frpc     # c++ namespace name

Info:
  type: struct
  definitions:
    Name: { type: string, comment: "c++ std::string type" }

BankInfo:
  type: struct
  definitions:
    TestMap: { type: map<bool;u32>, comment: "c++ std::unordered_map type" }
    TestVector: { type: vector<string>, comment: "c++ std::vector type" }

HelloWorldApi:
  type: interface
  pattern: bi
  caller: HelloWorldClient
  callee: HelloWorldServer
  definitions:
    hello_world:
      web: # Generate web service definition
        path: "/hello/world"
        timeout: "9000"
      inputs:
        bank_info: {type: BankInfo}
        blance: {type: u64}
        date: {type: DateTime} # frpc DateTime type
      outputs:
        reply: {type: string}
        info: {type: Info}
        count: {type: u64}

UniInterface:
  type: interface
  pattern: uni
  caller: HelloWorldSender
  callee: HelloWorldReceiver
  definitions:
    hello_world:
      inputs:
        in: {type: string}
    notice:
      inputs:
        in: {type: i32}
        info: {type: string}

Stream:
  type: interface
  pattern: bi_stream
  caller: StreamClient
  callee: StreamServer
  definitions:
    hello_world:
      inputs:
        bank_name: {type: string}
      outputs:
        reply: {type: string}
