Beego Compress provides an automated system for compressing JavaScript and Css files
It default use Google Closure Compiler for js, and Yui Compressor for css
After create a config file, you can simple use it in beego.
Move compiler.jar and yuicompressor.jar to your beego app path. Parallel with static path.
BTW: Of course you can integrated it with other framework or use it as a command line tool.
func SettingCompress() {
// load json config file
isProductMode := false
setting, err := compress.LoadJsonConf("conf/compress.json", isProductMode, "http://127.0.0.1/")
if err != nil {
beego.Error(err)
return
}
// after use this api, can run command from shell.
setting.RunCommand()
if isProductMode {
// if in product mode, can use this api auto compress files
setting.RunCompress(true, false, true)
}
// add func to FuncMap for template use
beego.AddFuncMap("compress_js", setting.Js.CompressJs)
beego.AddFuncMap("compress_css", setting.Css.CompressCss)
}
In tempalte usage
...
<head>
...
{{compress_css "lib"}}
{{compress_js "lib"}}
{{compress_js "app"}}
</head>
...
