View

The view package provides a type-safe and hierarchical (layouts) way to load and render Go HTML templates using the standard library's html/template package. It supports loading templates from any sources exposed as fs.FS. The package comes with no external dependencies and is designed for use in web applications.

This is extremly light library based on gist https://gist.github.com/reddec/312367d75cc03f1ee49bae74c52a6b31 and has zero external dependecies.

Key points:

• Hierarchical: The templates are loaded in a hierarchical way, allowing you to have a base layout and extend it with partials or views at different levels. Layouts defined in each directory as _layout.gohtml file and can be extended.
• Type-safe: The package provides a type-safe wrapper around the standard html/template library using a custom View struct.

Example

Layout

├── main.go
└── views
    ├── _layout.gohtml
    ├── index.gohtml
    └── info
        ├── _layout.gohtml
        └── about.gohtml

And the code

package main

import (
	"embed"
	"fmt"
	"net/http"

	"github.com/reddec/view"
)

//go:embed all:views
var views embed.FS

func main() {
	index := view.Must(view.New[string](views, "views/index.gohtml"))
	about := view.Must(view.New[string](views, "views/info/about.gohtml"))
	http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
		index.Render(w, "the index page")
	})
	http.HandleFunc("/info/about", func(w http.ResponseWriter, r *http.Request) {
		about.Render(w, "made by RedDec")
	})
	fmt.Println("ready on :8080")
	panic(http.ListenAndServe(":8080", nil))
}

• note: all:view - the all: prefix is required in order to include files with underscore in name prefix
