View
Iris supports 8 template engines out-of-the-box, developers can still use any external golang template engine,
as Context.ResponseWriter() is an io.Writer.
All template engines share a common API i.e. Parse using embedded assets, Layouts and Party-specific layout, Template Funcs, Partial Render and more.
| # | Name | Parser |
|---|---|---|
| 1 | HTML | html/template |
| 2 | Blocks | kataras/blocks |
| 3 | Django | flosch/pongo2 |
| 4 | Pug | Joker/jade |
| 5 | Handlebars | aymerick/raymond |
| 6 | Amber | eknkc/amber |
| 7 | Jet | CloudyKit/jet |
| 8 | Ace | yosssi/ace |
You can serve quicktemplate files too, simply by using the Context.ResponseWriter, take a look at the iris/_examples/view/quicktemplate example.
Overview
// file: main.go
package main
import "github.com/kataras/iris/v12"
func main() {
app := iris.New()
// Load all templates from the "./views" folder
// where extension is ".html" and parse them
// using the standard `html/template` package.
app.RegisterView(iris.HTML("./views", ".html"))
// Method: GET
// Resource: http://localhost:8080
app.Get("/", func(ctx iris.Context) {
// Bind: {{.message}} with "Hello world!"
ctx.ViewData("message", "Hello world!")
// Render template file: ./views/hello.html
ctx.View("hello.html")
})
// Method: GET
// Resource: http://localhost:8080/user/42
app.Get("/user/{id:int64}", func(ctx iris.Context) {
userID, _ := ctx.Params().GetInt64("id")
ctx.Writef("User ID: %d", userID)
})
// Start the server using a network address.
app.Listen(":8080")
}
<!-- file: ./views/hello.html -->
<html>
<head>
<title>Hello Page</title>
</head>
<body>
<h1>{{.message}}</h1>
</body>
</html>
Template functions
package main
import "github.com/kataras/iris/v12"
func main() {
app := iris.New()
tmpl := iris.HTML("./templates", ".html")
// builtin template funcs are:
//
// - {{ urlpath "mynamedroute" "pathParameter_ifneeded" }}
// - {{ render "header.html" }}
// - {{ render_r "header.html" }} // partial relative path to current page
// - {{ yield }}
// - {{ current }}
// register a custom template func.
tmpl.AddFunc("greet", func(s string) string {
return "Greetings " + s + "!"
})
// register the view engine to the views, this will load the templates.
app.RegisterView(tmpl)
app.Get("/", hi)
// http://localhost:8080
app.Listen(":8080")
}
func hi(ctx iris.Context) {
// render the template file "./templates/hi.html"
ctx.View("hi.html")
}
<!-- file: ./templates/hi.html -->
<b>{{greet "kataras"}}</b> <!-- will be rendered as: <b>Greetings kataras!</b> -->
Embedded
View engine supports bundled(https://github.com/go-bindata/go-bindata) template files too.
go-bindata gives you two functions, Assset and AssetNames,
these can be set to each of the template engines using the .Binary function.
Example code:
package main
import "github.com/kataras/iris/v12"
func main() {
app := iris.New()
// $ go get -u github.com/go-bindata/go-bindata/v3/go-bindata
// $ go-bindata ./templates/...
// $ go build
// $ ./embedding-templates-into-app
// html files are not used, you can delete the folder and run the example
app.RegisterView(iris.HTML("./templates", ".html").Binary(Asset, AssetNames))
app.Get("/", hi)
// http://localhost:8080
app.Listen(":8080")
}
type page struct {
Title, Name string
}
func hi(ctx iris.Context) {
// {{.Page.Title}} and {{Page.Name}}
ctx.ViewData("Page", page{Title: "Hi Page", Name: "iris"})
ctx.View("hi.html")
}
A real example can be found here: https://github.com/kataras/iris/tree/master/_examples/view/embedding-templates-into-app.
Reload
Enable auto-reloading of templates on each request. Useful while developers are in dev mode as they no neeed to restart their app on every template edit.
Example code:
pugEngine := iris.Pug("./templates", ".jade")
pugEngine.Reload(true) // <--- set to true to re-build the templates on each request.
app.RegisterView(pugEngine)
