Produces a graphql schema from your protos.
Usage:
make compiles Linux and MacOS binaries to ./target/protoc-gen-graphql.linux and ./target/protoc-gen-graphql.darwin.
To generate a schema.graphql file with protoc, copy or symlink the platform-specific binary to protoc-gen-graphql, then run:
protoc \
-I your_protos_dir \
--plugin ./protoc-gen-graphql \
--graphql_out=file_out=schema.graphql,root_query=GraphQL:your_schemas_dir \
your_protos_dir/message.proto
