How to transform into a back-end golang engineer

Foreword:

With the development of Internet technology, golang has gradually become one of the mainstream languages ​​​​in large-scale distributed systems. Its high concurrency, high performance and concise and easy-to-understand syntax features are widely accepted. In the architecture of the website, back-end engineers play a key role. In the project development of our team, golang has also become the primary choice. Therefore, we need a group of back-end golang engineers to join our team to jointly promote our project to success.

This article mainly discusses how to transform into a back-end golang engineer. I hope it can be helpful to students who are interested in entering the back-end field.

1. Learn the basic grammar of golang

To learn any language, you must first master its basic grammar, and golang is no exception. The grammatical features of golang are relatively simple and will not be too difficult to learn. Here are some main syntax elements:

Variables: Variables are a very basic concept in golang programming and can store data and data types. Golang uses the var keyword to declare variables, for example: var x int = 10.

Function: The definition method of function in golang is func funcName (parameter list) (return value) {}. Functions are also a very basic concept and are essential when we write golang programs.

Structure: Structure is also a very basic concept in golang. It can combine multiple variables of different types into a whole. For example, define a structure in golang:

type Person struct {

Name string
Age  int

}

The above three elements are very basic contents in golang grammar and need to be understood by students. and mastery.

2. Golang network programming

For back-end engineers, network programming is one of the very important skills. Golang has built-in very powerful network programming support, which can easily implement network server related functions. We need to master the following aspects:

TCP/UDP programming: The two common protocols in network programming are TCP and UDP. Golang provides support for tcp and udp protocols in the standard library.

HTTP protocol: golang has a built-in http package, which makes it very convenient to program the http protocol.

WebSocket: golang also has a built-in websocket package, which can quickly implement the programming of the websocket protocol.

3. Golang concurrent programming

One of the biggest features of golang is that it supports high concurrency, so we will definitely use knowledge about concurrent programming in golang back-end programming. In golang, concurrent programming is very simple. Golang provides two special mechanisms: goroutine (coroutine) and channel to support concurrent programming.

Coroutines: Coroutines in golang are implemented by the golang scheduler, which can schedule tasks very efficiently. We can use the go keyword to start a coroutine, for example: go funcName().

Channel: Channel in golang is a mechanism for communication between coroutines. Data can be sent and received between coroutines. The underlying implementation of channel in golang is based on the communication model of the Go language kernel, which can transfer data very conveniently.

4. Golang Framework

After learning the basic syntax, network programming and concurrent programming of golang, we need to start learning the golang framework. The design of the golang framework is very suitable for distributed systems. Since the Golang compiler itself has excellent cross-platform capabilities, it is very convenient to build cross-platform software.

Currently, the more popular frameworks in the golang field include gin, beego, echo, etc. Choose the most appropriate framework for development according to specific business scenarios and needs. For example, using the gin framework can quickly implement RESTful API interfaces, while using the beego framework supports a development model similar to MVC.

5. Summary

This article briefly introduces how to transform into a back-end golang engineer, which mainly involves golang basic syntax, network programming, concurrent programming and golang framework, etc. Knowledge. If you have a certain programming foundation and master the above aspects of knowledge, you can become a qualified golang back-end engineer. I hope that students who are interested in entering the back-end field can study hard and jointly promote the development of golang technology!
