Package templates is a thin wrapper around html/template.
The templates package main function is to create a collection of templates found in a templates directory
The templates directory structure only requires that a 'views' directory exist and it contains at least one HTML template. An HTML template will be created for each template found in the views directory.
All other views that are not in the 'views' directory will be made available to each view template
Example directory structure
templates/
base.html
views/
index.html
about.html
partials/
css.html
nav.html
scripts.html
Template Examples

{{ end }}
</ul>

{{ end }}Usage:
// templates collection
var tmpls *templates.Templates
// path to template directory
var templatesPath = "templates/"
func init() {
var err error
templs, err = templates.New().Parse(templatesPath)
if err != nil {
log.Fatal(err)
}
}
fund main() {
// the first method call specifies the 'views/index.html' view and the Render call
// specifies that the 'base.html' template should be rendered to os.Stdout
err := tmpls.Get("views/index.html").Render(os.Stdout, "base.html", nil)
if err != nil {
// handle error
}
