Asset Management Pakcage for web app in Go language. Inspired by Rails Asset Pipeline.
Use Train to mange you asset's dependencies. Enable you to write javascript or stylesheet in the following way:
app.js
//= require jquery.js
$(function(){
// Do something cool
})app.css
/*
*= require reset
*/
body{
}These files will become:
/*! jQuery v@1.8.0 jquery.com | jquery.org/license */
(function(a,b){function G(a){var b=F[a]={};return p.each(a.split(...
$(function(){
// Do something cool
})html, body, div, span, applet, object, iframe,
h1, h2, h3, h4, h5, h6, p, blockquote, pre,
a, abbr, acronym, address, big, cite, code,
del, dfn, em, img, ins, kbd, q, s, samp,
small, strike, strong, sub, sup, tt, var,
b, u, i, center,
....
body{
} import "github.com/shaoshing/train"
http.HandleFunc(train.Config.AssetURL, http.HandlerFunc(train.Handler)) import "github.com/shaoshing/train"
type Layout struct{
Train train.Helpers // Export Train helpers to templates
}
func main() {
layout := Layout{Train: train.Helpers{}}
html := `
{{.Layout.Train.JavascriptTag "app"}}
{{.Layout.Train.StylesheetTag "app"}}
`
tmpl, _ := template.New("").Parse(html)
tmpl.Execute(os.Stdout, layout)
//
// <script src="/assets/javascripts/jquery.js?12345"></script>
// <script src="/assets/javascripts/app.js?12345"></script>
//
// <link rel="stylesheet" href="/assets/stylesheets/reset.css?12345">
// <link rel="stylesheet" href="/assets/stylesheets/app.css?12345">
}Install the command line tool to bundle and compress assets automatically:
go install github.com/shaoshing/train/train
train
-> clean bundled assets
-> copy assets from assets
-> bundle assets with require directive
-> compress assets
ls public/assetsThe train tool will bundle your assets into the public/assets folder, with all files expaneded and compressed (by YUI compressor). You can then use any web servers (nginx, apache, or the Go's file server) to serve these static files. The template helpers will also stop expanding files if it found the public assets folder. That is, the following code:
{{.Layout.Train.JavascriptTag "app"}}
{{.Layout.Train.StylesheetTag "app"}}Will become:
<script src="/assets/javascripts/app.js?12345"></script>
<link rel="stylesheet" href="/assets/stylesheets/app.css?12345">
