We are going to create a stack where: Microservices are communicating using gRPC using protobuf for serializing-deserializing Frontend is consuming APIs through graphQL React is used to render UI Step 1: gRPC Service You need a gRPC server running for the tutorial. If you don't have one of your own, you can use the one... Continue Reading →
I wrote past few posts based on my notes from The Go Progamming Language by Donovan. In this article, we will try to make a go serverand expose rest APIs to read an write values from MySQL database. We will assume that your mySQL server is running at 3306 port in your local computer. net/http... Continue Reading →
Problem Statement Given n - bytes, implement a file system that supports following actions: Create File Update File Read File Delete File If you want a good start point for a small low level design problem, this post on designing a ride hailing service might be a good start. Demystifying Problem Statement When the problem... Continue Reading →
You might want to read the previous post in the series. Composite types created by combining the basic types like int, float etcetra. Arrays An array is a fixed length sequence of zero or more elements of particular type Because of the fixed length constraints, Arrays are rarely used in Go if "..." appears in... Continue Reading →
You might want to browse the previous post on this series. Integers Go provides both signed and unsigned integer type There are four different size of signed integer type; 8, 16, 32, 64 bits, represented by int8, int16, int32 and int64 Similarly there are four different size of unsigned integer types; 8, 16, 32, 64...
