👋 Welcome	🧬 Template engine middlewares for Fiber.	1

This package provides universal methods to use multiple template engines with the Fiber web framework using the new Views interface that is available from > v1.11.1. Special thanks to @bdtomlin & @arsmn for helping!

9 template engines are supported:

Installation

Go version 1.17 or higher is required.

go get -u github.com/gofiber/fiber/v2
go get -u github.com/gofiber/template/any_template_engine/vX

Example

package main

import (
	"log"

	"github.com/gofiber/fiber/v2"

	// To use a specific template engine, import as shown below:
	// "github.com/gofiber/template/pug"
	// "github.com/gofiber/template/mustache"
	// etc..

	// In this example we use the html template engine
	"github.com/gofiber/template/html/v2"
)

func main() {
	// Create a new engine by passing the template folder
	// and template extension using <engine>.New(dir, ext string)
	engine := html.New("./views", ".html")

  	// We also support the http.FileSystem interface
	// See examples below to load templates from embedded files
	engine := html.NewFileSystem(http.Dir("./views"), ".html")

	// Reload the templates on each render, good for development
	engine.Reload(true) // Optional. Default: false

	// Debug will print each template that is parsed, good for debugging
	engine.Debug(true) // Optional. Default: false

	// Layout defines the variable name that is used to yield templates within layouts
	engine.Layout("embed") // Optional. Default: "embed"

	// Delims sets the action delimiters to the specified strings
	engine.Delims("{{", "}}") // Optional. Default: engine delimiters

	// AddFunc adds a function to the template's global function map.
	engine.AddFunc("greet", func(name string) string {
		return "Hello, " + name + "!"
	})

	// After you created your engine, you can pass it to Fiber's Views Engine
	app := fiber.New(fiber.Config{
		Views: engine,
	})

	// To render a template, you can call the ctx.Render function
	// Render(tmpl string, values interface{}, layout ...string)
	app.Get("/", func(c *fiber.Ctx) error {
		return c.Render("index", fiber.Map{
			"Title": "Hello, World!",
		})
	})

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

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

embedded Systems

We support the http.FileSystem interface, so you can use different libraries to load the templates from embedded binaries.

pkger

	"github.com/markbates/pkger"
)

func main() {
	engine := html.NewFileSystem(pkger.Dir("/views"), ".html")

	app := fiber.New(fiber.Config{
		Views: engine,
	})

	// run pkger && go build
}

	"github.com/gobuffalo/packr/v2"
)

func main() {
	engine := html.NewFileSystem(packr.New("Templates", "/views"), ".html")

	app := fiber.New(fiber.Config{
		Views: engine,

	"github.com/<user>/<repo>/static"
)

func main() {
	engine := html.NewFileSystem(static.HTTP, ".html")

	app := fiber.New(fiber.Config{
		Views: engine,
	})

}

Benchmarks

Simple

Extended

Benchmarks were ran on Apple Macbook M1. Each engine was benchmarked 20 times and the results averaged into a single xlsx file. Mustache was excluded from the extended benchmark
