}

Page is the basis to render complete HTML pages. An arbitrary View or ViewWithURL can be used to render other text formats like CSS or JSON.

A HTML5 Boilerplate template is used by default. See:

  • gostart/templates/html5boilerplate.html
  • gostart/static/css/html5boilerplate/normalize.css
  • gostart/static/css/html5boilerplate/poststyle.css

Note: In the current version Mustache is always used as templates system. This will be changed to the Go v1 template system in the Go v1 syntax release.

Most HTML head and script specific text is written by PageWriteFunc functions that receive the request context as an argument. That way the content can be created dynamically.

Wrapper functions for static content are provided for convenience. See functions under PageWriteFunc below.

Example: 

&Page{WriteTitle: func(context *Context, writer io.Writer) (err error) {
	writer.Write([]byte("Could be a dynamic title"))
	return nil
}}

&Page{WriteTitle: PageTitle("Static Title")}

To avoid reading the same data multiple times from the database in PageWriteFunc or dynamic views in the content structure, OnPreRender can be used to query and set page wide data only once at the request context.Data.

Example: 

&Page{
	OnPreRender: func(page *Page, context *Context) (err error) {
		context.Data = &MyPerPageData{SomeText: "Hello World!"}
	},
	Content: DynamicView(
		func(context *Context) (view View, err error) {
			myPerPageData := context.Data.(*MyPerPageData)
			return HTML(myPerPageData.SomeText), nil
		},
	),
}
