Beego Compress provides an automated system for compressing JavaScript and Css files
It defaults to Minify which is a native Golang minifier.
Optionally you can use Google Closure Compiler for js, and Yui Compressor for css
After create a config file, you can simple use it in beego.
In case you will use the optional compilers, 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
isProdMode := false //production mode
setting, err := compress.LoadJsonConf("conf/compress.json", isProdMode, "http://127.0.0.1")
if err != nil {
beego.Error(err)
return
}
// after use this api, can run command from shell.
setting.RunCommand()
if isProdMode {
// if in prod 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.Compress)
beego.AddFuncMap("compress_css", setting.Css.Compress)
}

when use api setting.RunCommand()
$ go build app.go
$ ./app compress
compress command usage:
js - compress all js files
css - compress all css files
all - compress all files
$ ./app compress js -h
Usage of compress command: js:
-force=false: force compress file
-skip=false: skip all cached file
-v=false: verbose info
$ ./app compress css -h
Usage of compress command: css:
-force=false: force compress file
-skip=false: skip all cached file
-v=false: verbose info
use -force for re-create dist file but not skip cached.
use -skip can skip all cached file and re-compress.
All api can view in GoWalker
