Composable HTML components in Golang
Daz is a "functional" alternative to using templates, and allows for nested components/lists Also enables template-free server-side rendered components with support for nested lists. It is inspired by HyperScript.
A component can be created and used with simple functions:
// Example prop for a component
type User struct {
Name string
// ...
}
func MyComponenet(user User) HTML {
return H(
"div",
Attr{"class": "bg-grey-50"},
user.Name,
)
}
func Root() HTML {
user := User{Name: "Daz"}
return H("html", MyComponenet(user))
}
// And used in a handler:
func Handler(w http.ResponseWriter, r *http.Request) {
w.Write([]byte(Root()()))
}Lists can be easily created without needing to embed a range / end in a template:
items := []HTML{
H("li", "item one"),
H("li", "item two"),
}
element := H("ul", Attr{"class": "bg-grey-50"}, items)
div := H("div", element)import (
"github.com/stevelacy/daz"
)
Create a HTML element:
H("div", ...attrs)HTML attributes:
Attr{
"class": "app",
"onClick": "javascriptFunc()",
}This will bypass HTML sanitization and allow for direct injecting
injection := "<script>alert('xss')</script>"
root := H("div", UnsafeContent(injection))
// <script>alert('xss')</script>
