Creating a project with Golang

Overview

You can run a go file with out making a project. But the standard way to use go is to create a project or you can call it a space where you will be putting your go code, on the other hand it is a work space, but in Go Lang we call it module. In Go Lang modules are the official way of organize go code.

in this blog I am going to explain the way you create a model and first hello world with that project.

Explanation

To Module you need to run the command bellow

  	go mod init <module name>

If you can see I have named my module github.com/TahimFaisal/golang. the name of the module is called module initializer. this is the standard way of initialization. And for the go get command it will

it will know where to go and get the mod if it cannot find the mod locally.

Okay, soon after you ran the command you will get a file named go.mod in your working directory

it will be having module initializer and the version of go your using.

now create a main.go file and write the code bellow


	package main
	import "fmt"
	
	func main() {
		fmt.Println("hello world!!")
	}

you can run it in old way. using command bellow

go run .
go run main.go

but now have initialize the project so you can run it from anywhere in your local pc by using the module initializer. By using the command bellow.

	    go run <module initializer>

CRUD with Golang

Overview this blog will be about a basic crud app with golang . this app will provide API to store, update, delete information . you need to know the basics of golang to understand this project. if you do not have the basics knowledge about golang I would suggest you to read my previous blog. I have uploaded my code in GitHub. click the link to clone or download this project I am going to talk about the topic below. Project setup Data handling controller Project setup Initiate mod and set up project as per golang. if you don't know how to setup golang project i would suggest you to have a look at my blog Creating a project with golang . this is a really short blog. you will have a quick over view of how to setup a project with golang. so now that you have setup the project then the folder structure will be as below. Data Handling data store, delete and update will be handled in the user module. code is given below package moduls import ( "errors&quo

Primitive data type of Golang

Overview In this blog I am going to talk about the date types and variables in go. and the topics bellow Declaring and initializing variables explicit initialization of variables implicit initialization of variables complex data type list of data type Pointer pointer operator dereferencing operator address of operator Constant Iota and constant expression Declaring and initializing variables there are 2 ways you can declarer and initialize a variable they are explicit initialization variables implicit initialization variables Explicit initialization of variables in this way you have to tell the compiler every thing you need to declare a variable. var i int i = 20 var j int = 3 fmt.Println(i,j) var f float32 = 32.233 fmt.Println(f) in this way we are explicitly telling what will be the input type for that variable. Implicit initialization of variables in this way of declaring a variable. we don't have to tell the compiler what type of data it will take on that

Functions and Methods of golang

Overview In this blog i am going to talk about the functions and methods in golang. which is a important topic in go. if you have not read the previous blog or do not have a basic knowledge about go the i would suggest you to have a look at my other blog. Functions Methods Functions you can declare a function as below. you don't need to declare return type unless your not returning something from your function. you get the return value in a way that is explained in the example code . func <function name > ( <parameter> <parameter type> ) ( <return type> ){} Example Code : package main import ("fmt") func main() { test1() // example 1 sum := test2() // example 2 fmt.Println("sum =",sum) sum2,error:= test3(30,40) // example 3 fmt.Println("sum 2 =",sum2,error) sum3,_:= test3(80,60) // example 4 fmt.Println("sum 2 =",sum3) su
