How to Communication Golang with MySQL Database

Package atau Library

import  "github.com/go-sql-driver/mysql"

Project Initialization

Prepare a new folder with the name mysql-native, then initialize the Golang module to make it more modular. Here’s a quick command.

Golang Programming

The Golang programming language (or commonly known as Go) is currently in great demand by programmers, especially those working in the fields of Backend Developer, Software Engineer or those who work as FullStack Developers. Learning Golang is indeed relatively easy because the code syntax is simple so that when someone wants to learn Golang programming it is easier and easier to implement. The Golang programming language compared to other languages is easier to understand because of the conciseness of the program code using go (golang).

Usage Channel Select Range Timeout

The existence of channels really helps us to manage the goroutines that are running in our program. There are times when we also need to manage many goroutines and many channels are needed. So, this is where select comes in handy. select allows us to control data communication through channels. It is used in the same way as the switch selection condition.

Channel Introduction to Golang

A channel is a link from one goroutine to another and this channel is synchronous because of blocking data processes. Channels can be defined as variables with the keyword chan. This variable has the task of sending and receiving data.

Introduction of Go Routine on Golang

Use go-routine when the process to be executed as a goroutine must be wrapped in a function. When calling the function, the go command is added in front of it. Thus the process will be detected as a new goroutine.

How to Overcome Handling Errors in Golang

Currently, Santekno will discuss error handling in the Golang language. We will learn from easy handling to some very complex implementations. Golang already provides easy error handling, we can also make slight modifications so that the error can be more easily understood by ourselves and the people who will collaborate with us in the future. The first thing we will do is customize Golang’s default Error.

Techniques for Creating Mocking Unit Tests in Golang

When we create a function or code, sometimes we have difficulty carrying out unit tests at several points that we cannot cover with unit tests. So here are several technical ways to carry out unit tests using the mocking technique. But actually we can also use third-party which is already available in several libraries so we just need to use it straight away.

How to Create Integration Tests in Golang

Carrying out integration tests for APIs means that we must at least be able to run the application first so that integrated testing can be carried out. We need to prepare several cases, test cases that cover the needs of the integration test. For example, the API Endpoint' that we have worked on has a database, cache` or other external resource that is related to the continuity of the API Endpoint.

How to Create Unit Tests Using the moq Library in Golang

Carrying out unit tests using this mocking method is usually used if several functions have been carried out in interface format so that we can assume that if we call the interface function we believe that it should produce the correct program.

How to Create Benchmark Units in Golang

The testing package in Golang Programming, apart from containing tools for testing, also contains tools for benchmarking. The way to create a benchmark itself is quite easy, namely by creating a function whose name begins with Benchmark and whose parameters are of type *testing.B.

How to Create Unit Tests in Golang

Unit Testing Using the Go Library

programming is not easy, even the best programmers cannot write programs that work exactly as desired every time. Therefore, an important part of the software development process is testing. Writing tests for our code is a good way to ensure quality and increase reliability.

Getting to Know Hashes Cryptography in Golang

Hashes & Cryptography

The hash function takes a set of data and reduces it to a smaller fixed size. Hash is often used in programming for everything from searching data to easily detecting changes. The hash functions in Go are divided into two categories namely cryptographic and non-cryptographic. Non-cryptographic hash functions can be found under the hash package and include adler32, crc32, crc64 and fnv.
