HTML is the official Go template engine html/template, to see the original syntax documentation please click here

Info:

All templates within the specified view directory are analyzed and compiled at the beginning to increase the performance when using them. Thus it should be noted that no definition with the same name should exist, otherwise they will overwrite each other. For templating the {{embed}} tag should be used

Basic Example

./views/index.html

{{template "partials/header" .}}

<h1>{{.Title}}</h1>

{{template "partials/footer" .}}

./views/partials/header.html

<h2>Header</h2>

./views/partials/footer.html

<h2>Footer</h2>

./views/layouts/main.html

<!DOCTYPE html>
<html>
  <head>
    <title>Main</title>
  </head>

  <body>
    {{embed}}
  </body>
</html>
package main

import (
	"log"

	"github.com/gofiber/fiber/v2"
	"github.com/gofiber/template/html/v2"
)

func main() {
	// Create a new engine
	engine := html.New("./views", ".html")

	// Or from an embedded system
	// See github.com/gofiber/embed for examples
	// engine := html.NewFileSystem(http.Dir("./views"), ".html")

	// Pass the engine to the Views
	app := fiber.New(fiber.Config{
		Views: engine,
	})

	app.Get("/", func(c *fiber.Ctx) error {
		// Render index
		return c.Render("index", fiber.Map{
			"Title": "Hello, World!",
		})
	})

	app.Get("/layout", func(c *fiber.Ctx) error {
		// Render index within layouts/main
		return c.Render("index", fiber.Map{
			"Title": "Hello, World!",
		}, "layouts/main")
	})

	app.Get("/layouts-nested", func(c *fiber.Ctx) error {
		// Render index within layouts/nested/main within layouts/nested/base
		return c.Render("index", fiber.Map{
			"Title": "Hello, World!",
		}, "layouts/nested/main", "layouts/nested/base")
	})

	log.Fatal(app.Listen(":3000"))
}

Example with embed.FS

package main

import (
    "log"
    "net/http"
    "embed"

    "github.com/gofiber/fiber/v2"
    "github.com/gofiber/template/html"
)

//go:embed views/*
var viewsfs embed.FS

func main() {
    engine := html.NewFileSystem(http.FS(viewsfs), ".html")

    // Pass the engine to the Views
    app := fiber.New(fiber.Config{
        Views: engine,
    })


    app.Get("/", func(c *fiber.Ctx) error {
        // Render index - start with views directory
        return c.Render("views/index", fiber.Map{
            "Title": "Hello, World!",
        })
    })

    log.Fatal(app.Listen(":3000"))
}

and change the starting point to the views directory

./views/index.html

{{template "views/partials/header" .}}

<h1>{{.Title}}</h1>

{{template "views/partials/footer" .}}

Example with innerHTML

package main

import (
    "embed"
    "html/template"
    "log"
    "net/http"

    "github.com/gofiber/fiber/v2"
    "github.com/gofiber/template/html"
)

//go:embed views/*
var viewsfs embed.FS

func main() {
    engine := html.NewFileSystem(http.FS(viewsfs), ".html")
    engine.AddFunc(
        // add unescape function
        "unescape", func(s string) template.HTML {
            return template.HTML(s)
        },
    )

    // Pass the engine to the Views
    app := fiber.New(fiber.Config{Views: engine})

    app.Get("/", func(c *fiber.Ctx) error {
        // Render index
        return c.Render("views/index", fiber.Map{
            "Title": "Hello, <b>World</b>!",
        })
    })

    log.Fatal(app.Listen(":3000"))
}

and change the starting point to the views directory

./views/index.html

<p>{{ unescape .Title}}</p>

html output

<p>Hello, <b>World</b>!</p>
