Introduction to RPC using Go and Node

The text provides a detailed tutorial on building a remote procedure call (RPC) server using Go and an RPC client using Node.js, aimed at facilitating client-server communication by executing functions on a remote server. The guide begins with prerequisites, such as installing Go, Node, and Protocol Buffers, and then walks through creating an RPC server capable of handling chat messages and user details using protocol buffers for data serialization. It outlines the process of generating Go code from protocol buffer definitions and implementing server methods in Go to handle requests. The tutorial then shifts to setting up an RPC client in Node.js, using the node-grpc-client package to interact with the server. The text emphasizes practical steps, like creating necessary files and directories, writing and executing code, and provides insights into monitoring tool LogRocket for maintaining and debugging Node-based applications. By the end of the guide, readers should be able to establish a basic RPC communication setup with examples available on GitHub.
