在 Golang Web 编程的世界里，君不言高性能则已，言高性能必称 Iris。彩虹女神的名号响彻寰宇、名动江湖，单论一个快字，无人能出其右，就连以简洁轻量著称于世的 Gin 也难以望其项背，只见彩虹女神 Iris 回眸一笑撩人心扉：“尽管你们也不是那么慢，但我还是快那么一点点 ……”，本次就让咱们来一睹彩虹女神 Iris 的芳颜，感触宇宙最快 Web 框架的神乎其神。
女神本神 (Iris)
抉择一款框架有诸多的参考层面，比方灵活性、扩展性、API 敌对水平、文档具体水平、我的项目活跃度、社区奉献等等，然而性能和内存占用相对是优先参考的一个重要层面，原因无他，天下文治，唯快不破，正所谓一快遮百丑，经济上行，降本增效的大背景之下，高性能框架无疑占据极大的劣势，说白了，老本相仿的前提下，我单位工夫内网络申请吞吐量是你的一倍，还没使劲，你就倒下了，你怎么跟我打？游戏还没开始，就曾经完结了。
空口白牙，不足为据，参见 2022 年最新申请吞吐量比照图：
事实上，Iris 实质上也是社区驱动的 Go 语言 Web 框架，反对 http2/3，齐备的 MVC 反对，奉行极简主义格调，轻量化与扼要格调比起 Gin 来说，也不遑多让，与此同时，社区活跃度和文档反对都十分到位，但其领有的极其恐怖的高性能个性，其余框架则是可望不可即。在 Iris 身上，咱们能够看到她对性能的近乎于偏执的完满谋求，Iris 为了优化性能，不惜本人开发和集成最快的组件，比方日志记录内置了 golog 模块，比方 json 序列化就抉择了第三方库 jsoniter，从框架设计的态度上，极尽完满之能事。
建设我的项目 IrisBlog
参照 Iris 官网文档：https://github.com/kataras/ir…\_ZH.md，咱们借助彩虹女神 Iris 的垂爱，打造一款史上最快的在线博客零碎，首先建设文件夹 IrisBlog:
mkdir IrisBlog
cd IrisBlog随后通过 go mod 命令初始化我的项目：
C:\Users\liuyue\www\iriblog>go mod init IrisBlog
go: creating new go.mod: module IrisBlog对于 go mod 不熟的敌人，请移玉步至层次分明井然有条,Go lang1.18 入门精炼教程，由白丁入鸿儒，Go lang 包管理机制 (package)EP10，对于 go mod 的应用，这里不再赘述。
接着，因为诸位能够了解的起因，请确保应用国内的装置源：
go env -w GOPROXY=https://goproxy.cn,direct随后装置彩虹女神 Iris：
go get -u github.com/kataras/iris零碎返回：

接着在我的项目的根目录建设 main 入口文件：
package main
import "github.com/kataras/iris/v12"
func main() {app := iris.New()
app.Use(iris.Compression)
app.Get("/", func(ctx iris.Context) {ctx.HTML("你好 <strong>%s</strong>!", "女神")
})
app.Listen(":5000")
}随后在终端启动 Iris 服务：
go run main.go零碎返回：
Iris Version: 12.2.0-beta4
Now listening on: http://localhost:5000
Application started. Press CTRL+C to shut down.还等什么？拜访 http://localhost:5000
万唤千呼始进去。
应用快捷键 control+ C 能够终止服务，随后能够再次运行 go run main.go 来从新编译启动服务。
Iris 我的项目热重启机制:fresh
家喻户晓，因为 Go lang 是编译型语言，每次批改代码之后都须要从新编译，Iris 目前没有内置代码热更新的工具，这里咱们能够应用三方包：fresh，如此，能够大幅提高咱们的 Iris 开发效率，在非我的项目目录执行命令：
go get github.com/pilu/fresh留神，这里肯定不能在我的项目的目录中执行装置命令，因为 go mod 模式会认为是我的项目依赖包，而不会在以后零碎的 bin 目录下生成可执行命令 fresh。
随后进入我的项目目录：
cd IrisBlog应用 fresh 命令启动 Iris 服务：
C:\Users\liuyue\www\iriblog>fresh
0:19:33 runner | InitFolders
0:19:33 runner | mkdir ./tmp
0:19:33 watcher | Watching .

0:19:46 app |
0:19:46 app | Now listening on: http://localhost:5000
Application started. Press CTRL+C to shut down.此时，我的项目内所有包文件都会被监控，当代码被批改后，会主动触发编译动作，原理大略相当于 Python 中 Tornado 框架的事件循环机制。
当咱们批改代码之后，fresh 会监控到批改动作，而后立即 build:
Application started. Press CTRL+C to shut down.

0:28:12 app |
Now listening on: http://localhost:5000
Application started. Press CTRL+C to shut down.如此，就不须要手动触发代码的编译了，简略不便。
如果有定制化需要，能够为以后我的项目增加配置文件 runner.conf:
root: .
tmp_path: ./fresh
build_name: runner_build
build_log: runner_build_errors.log
valid_ext: .go, .tpl, .tmpl, .html, .md, .log
no_rebuild_ext: .tpl, .tmpl, .html
ignored: assets, tmp, log
build_delay: 3000
colors: 1
log_color_main: cyan
log_color_build: yellow
log_color_runner: green
log_color_watcher: magenta
log_color_app: red能够定制化诸如监听的文件、编译日志、疏忽文件和目录，编译提早等等操作。
批改定制化配置文件后，针对配置文件启动 fresh 服务：
fresh -c runner.conf如此，fresh 服务会依据配置文件来进行监听编译动作。
结语
最低的系统资源开销，最高的单位工夫网络申请吞吐量，这是彩虹女神 Iris 对开发者们最好的馈赠，当咱们装置好 Iris 并且配置好热重启机制时，咱们也就走下了 Go 语言 web 开发万里长征的第一步，山高路远，城高池深，尽管前路艰险，但就算是鲁莽地开始，高明地实现，也好过眼高手低而不去做，你批准吗？
