protoc-gen-d2 is a plugin for Google's Protocol Buffers (protoc) that generates svg of the entities specified in the proto files. The idea is to improve a project documentation with a visual representation of the data.
Example
Given a proto such as:
syntax="proto3";
package example;
enum Status {
ACTIVE = 0;
INACTIVE = 1;
}
message Phone {
string number = 1;
}
message User {
string name = 1;
string email = 2;
Phone phone = 3;
Status status = 4;
}
message UserRequest {
string name = 1;
}
service UserService {
rpc GetUser (UserRequest) returns (User);
}
