grpcblog

Here's is the link to my Medium article which explains the implementation of the code

Implementation of a simple RPC service using Golang. The RPC service can create and save blog posts.

• Client sends a request to the server to create a blog post with a given title and content.
• The server saves the blog posts created to an in-memory storage.
• The blog posts created are also saved to a JSON file named blogs.json in the root directory.

Generating protocol buffer code

make clean : To clean up the generated proto files

make gen : To compile the proto file

This generates two files:

blog/blog_grpc.pb.go
blog/blog.pb.go

blog_grpc.pb.go : contains server and client stubs.

blog.pb.go : contains protocol buffer related code - responsible for binary serialization of data when it is transported between server and client.

Running the server and client

Run the server and client code in two separate terminal windows:

go run server/server.go

go run client/client.go
