Preface
go-zero is a web and rpc framework that integrates various engineering practices. The stability of the large concurrent server is guaranteed through flexible design, and it has withstood full actual combat tests.
go-zero includes a minimalist API definition and generation tool goctl, which can generate Go, iOS, Android, Kotlin, Dart, TypeScript, JavaScript code with one click according to the defined api file, and run it directly.
So awesome, why don't you want to try it? !
Go language environment construction
Configure GO locale
新增go的代理 GOPROXY=https://goproxy.io,direct,https://mirrors.aliyun.com/goproxy/,https://goproxy.cn,https://athens.azurefd.net,https://gonexus.dev
Set environment variables
Add %GOROOT%\bin;%GOPATH%\bin to the environment variable path
Configuration in vscode
Install plugin
The key is the configuration of the go language environment in vscode, as follows:

Play with goctl tool
Goctl is a code generation tool under the go-zero microservice framework. It can quickly improve development efficiency and allow developers to focus their time on business coding...
I didn't mention many information in the query, it was not clear, and always reported command not found: goctl error.
I also installed the goctl tool into the $GOPATH/bin directory
The environment variables are also configured, and finally found that all online blogs did not say that $GOPATH/bin was added to the system environment path variable. After joining, restart the computer and you can use the goctl tool normally.
Next, is to experience the goctl tool.
Experience goctl tool

to sum up
In addition to the goctl artifact, go-zero also has many small tools.
- Streaming data processing tool: fx. Such as lambda of java8, go-zero is also available! fx.Filter().Sort().Head(), makes the complex processing of the array simple.
- mapReduce reduces the service response time: mr.Finish(), mr.Map().Reduce(), say goodbye to the concurrent processing waitGroup.
- Integration of etcd service discovery: p2c algorithm discovery service, avoiding developers' point-to-point or nginx forwarding service, install an etcd and it's done.
- Jwt integrated api: easy to have a jwt background service.
- Integrate Prometheus: easily have a golang background service with monitoring.
Go language is mainly used for server-side development, and its positioning is to develop "large-scale software". It is suitable for many programmers to develop large-scale software together, and has a long development cycle and supports cloud computing network services. Go language allows programmers to develop quickly, and in the process of continuous growth of software, it allows programmers to more easily maintain and modify. It combines the efficiency of traditional compiled languages with the ease of use and expressiveness of scripting languages.
As a server programming language, Go language is very suitable for processing logs, data packaging, virtual machine processing, file systems, distributed systems, database agents, etc.; in terms of network programming, Go language is widely used in web applications, API applications, download applications, etc.; In addition, the Go language can also be used in the field of memory databases and cloud platforms. At present, many cloud platforms abroad are developed using Go.
