How to play go-Zero on Windows

Author: A peck debugIT

preface

Go-zero is a Web and RPC framework that integrates various engineering practices. The stability of large concurrent server is guaranteed by elastic design, which has been fully tested in practice.

Go-zero includes a minimalist API definition and generation tool called GoCTL, which can generate go, iOS, Android, Kotlin, Dart, TypeScript, and JavaScript code from defined API files in one click and run directly.

Why don’t you want to give it a try? !

Go language environment construction

Configure the GO language environment

Add go agent

GOPROXY=https://goproxy.io,direct,https://mirrors.aliyun.com/goproxy/,https://goproxy.cn,https://athens.azurefd.net,http s://gonexus.dev

Setting environment Variables

To the environment variable path%GOROOT%\bin; %GOPATH%\bin

Configuration in vscode

Installing a plug-in

The key is the configuration of the go language environment in vscode, as follows:

Play goctl tools

Goctl is a code generation tool under the Go-Zero microservices framework that can quickly improve development efficiency and allow developers to focus their time on business coding…

Command not found: goctl error

I also installed the goctl tool in the $GOPATH/bin directory

? x-oss-

$GOPATH/bin = $GOPATH/bin = $GOPATH/bin = $GOPATH/bin After joining, restart the computer, and the goctl tool can be used normally.

Next, experiment with the Goctl tool.

conclusion

In addition to the Goctl artifact, Go-Zero also has a number of gadgets.

Stream data processing tool: FX. Such as java8 lambda, go-zero also has! Fx.filter ().sort ().head (), which simplifies the complex processing of arrays.
List itemmapReduce reduces service latency: Mr. Finish(), Mr. Map().reduce (), say goodbye to the concurrent processing waitGroup.
Integration of ETCD service discovery: P2C algorithmic discovery services, avoid developers point-to-point or nginx forwarding services, install an ETCD and be done.
JWT integration API: Easily have a JWT backend service.
Integration with Prometheus: Easily have a Golang backend service with monitoring.

Go language is mainly used for server-side development, which is positioned to develop “large software”. It is suitable for many programmers to develop large software together, and the development cycle is long, and supports cloud computing network services. The Go language allows programmers to develop quickly, and it makes it easier to maintain and modify software as it grows. It combines the high 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 system, distributed system, database agent, etc. In network programming, Go language is widely used in Web applications, API applications, download applications, etc. In addition, Go language can also be used in the field of in-memory database and cloud platform, at present, many foreign cloud platforms are using Go development.
