Laptop-app-using-gRPC

Creating an app to search for laptop configurations using gRPC and protobuf in Go

protoc --proto_path=proto proto/*.proto --go_out=proto --go-grpc_out=proto

Steps completed till now:

• Created protobuf files

• Created auto generated go files for protobuf

• Added Makefile commands

• Sample generators with protobuf and Go

• Serializing proto messages

• Running end-to-end tests while serializing proto messages to both binary and json

• Comparing temp bins for json and binary files to differentiate between the file sizes, the bin files are more space efficient

• Created a proto service which uses unary-streaming gRPC and implemented a server to handle the unary RPC request

• Added a client to call the unary RPC server and using unit tests for the interaction between server and client

• Added server-streaming RPC to filter laptops while searching in store, then implementing server and client side RPC to handle calls and writing unit tests for them

• Defined client-streaming RPC to upload laptop image to store

• Added client calls and server handlers for client-streaming while implementing unit tests for both

• Implemented Bi-Directional Streaming RPC to create the functionality of rating laptops and writing the unit tests

• Added Evans CLI with gRPC reflection package for more intuitive gRPC actions

HOW TO RUN THE PROJECT

• download the file and go to its directory in the command line
• run the backend using command make server
• open another instance of your command line and run evans -r repl -p {PORT} with the port of the backend as the argument
• call package vyom1611.laptop_app, and service LaptopService
• use the command show service to see the available actions and call the desired RPCs using service {RPC}
• follow along the prompts showed
• Note: if you want to stop adding details into a list (ex. multiple storages in CreateLaptop), then use cmd/ctrl + D to escape
