Macaron middleware/handler for easily rendering serialized JSON and HTML template responses from Jade templates.
If you donot know about jade, learn from here
This middleware uses Jade implementation in Go go-floki/jade to render Jade templates.
Some examples can be found in examples
// main.go
package main
import (
"gopkg.in/macaron.v1"
"github.com/go-macaron/jade"
)
func main() {
m := macaron.Classic()
// render html templates from templates directory
m.Use(jade.Renderer())
m.Get("/", func(r jade.Render) {
r.HTML(200, "hello", map[string]string{
"foo": "bar",
})
})
m.Run()
}File templates/hello.jade
h2 Hello #{foo}!jade.Renderer comes with a variety of configuration options:
Layout is not supported.
// ...
m.Use(jade.Renderer(jade.Options{
Directory: "templates", // Specify what path to load the templates from.
Extensions: []string{".jade"}, // Specify extensions to load for templates.
Funcs: []template.FuncMap{AppHelpers}, // Specify helper function maps for templates to access.
Charset: "UTF-8", // Sets encoding for json and html content-types. Default is "UTF-8".
IndentJSON: true, // Output human readable JSON
}))
// ...By default the jade.Renderer middleware will attempt to load templates with a '.jade' extension from the "templates" directory. Templates are found by traversing the templates directory and are named by path and basename. For instance, the following directory structure:
templates/
|
|__ admin/
| |
| |__ index.jade
| |
| |__ edit.jade
|
|__ home.jade
Will provide the following templates:
admin/index
admin/edit
home
The jade.Renderer middleware will automatically set the proper Content-Type header based on which function you call. See below for an example of what the default settings would output (note that UTF-8 is the default):
// main.go
package main
import (
"gopkg.in/macaron.v1"
"github.com/go-macaron/jade"
)
func main() {
m := macaron.Classic()
m.Use(jade.Renderer())
// This will set the Content-Type header to "text/html; charset=UTF-8"
m.Get("/", func(r jade.Render) {
r.HTML(200, "hello", "world")
})
// This will set the Content-Type header to "application/json; charset=UTF-8"
m.Get("/api", func(r jade.Render) {
r.JSON(200, map[string]interface{}{"hello": "world"})
})
m.Run()
}In order to change the charset, you can set the Charset within the jade.Options to your encoding value:
// main.go
package main
import (
"gopkg.in/macaron.v1"
"github.com/go-macaron/jade"
)
func main() {
m := macaron.Classic()
m.Use(jade.Renderer(render.Options{
Charset: "ISO-8859-1",
}))
// This is set the Content-Type to "text/html; charset=ISO-8859-1"
m.Get("/", func(r jade.Render) {
r.HTML(200, "hello", "world")
})
// This is set the Content-Type to "application/json; charset=ISO-8859-1"
m.Get("/api", func(r jade.Render) {
r.JSON(200, map[string]interface{}{"hello": "world"})
})
m.Run()
}
