Tired of complex template languages?

Try HTML components in pure Go.

gomponents are HTML components written in pure Go. They render to HTML 5, and make it easy for you to build reusable components. So you can focus on building your app instead of learning yet another templating language.

Features

Check out www.gomponents.com for an introduction.

• Build reusable HTML components
• Write declarative HTML 5 in Go without all the strings, so you get
  • Type safety from the compiler
  • Auto-completion from the IDE
  • Easy debugging with the standard Go debugger
  • Automatic formatting with gofmt/goimports
• Simple API that's easy to learn and use (you know most already if you know HTML)
• Useful helpers like
  • Text and Textf that insert HTML-escaped text,
  • Raw and Rawf for inserting raw strings,
  • Map for mapping data to components and Group for grouping components,
  • and If/Iff for conditional rendering.
• No external dependencies
• Mature and stable, no breaking changes

Usage

go get maragu.dev/gomponents

package main

import (
	. "maragu.dev/gomponents"
	. "maragu.dev/gomponents/components"
	. "maragu.dev/gomponents/html"
)

func Navbar(authenticated bool, currentPath string) Node {
	return Nav(
		NavbarLink("/", "Home", currentPath),
		NavbarLink("/about", "About", currentPath),
		If(authenticated, NavbarLink("/profile", "Profile", currentPath)),
	)
}

func NavbarLink(href, name, currentPath string) Node {
	return A(Href(href), Classes{"is-active": currentPath == href}, g.Text(name))
}

(Some people don't like dot-imports, and luckily it's completely optional.)

For a more complete example, see the examples directory. There's also the gomponents-starter-kit for a full application template.

What's up with the specially named elements and attributes?

Unfortunately, there are some name clashes in HTML elements and attributes, so they need an El or Attr suffix, to be able to co-exist in the same package in Go.

I've chosen one or the other based on what I think is the common usage. In either case, the less-used variant also exists in the codebase:

• cite (Cite/CiteAttr, CiteEl also exists)
• data (DataEl/Data, DataAttr also exists)
• form (Form/FormAttr, FormEl also exists)
• label (Label/LabelAttr, LabelEl also exists)
• style (StyleEl/Style, StyleAttr also exists)
• title (TitleEl/Title, TitleAttr also exists)
