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 MyComponent(user User) HTML {
	return H(
		"div",
		Attr{"class": "bg-grey-50"},
		user.Name,
	)
}

func Root() HTML {
	user := User{Name: "Daz"}
	return H("html", MyComponent(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)

Install

import (
	"github.com/stevelacy/daz"
)

Usage

func H

Create a HTML element:

H("div", ...attrs)

struct Attr

HTML attributes:

Attr{
	"class": "app",
	"onClick": "javascriptFunc()",
}

func UnsafeContent

This will bypass HTML sanitization and allow for direct injecting

injection := "<script>alert('xss')</script>"
root := H("div", UnsafeContent(injection))
// <script>alert('xss')</script>
