Template interfaces

Fiber provides a Views interface to provide your own template engine:

  1. type Views interface {
  2.     Load() error
  3.     Render(io.Writer, string, interface{}, ...string) error
  4. }

Views interface contains a Load and Render method, Load is executed by Fiber on app initialization to load/parse the templates.

  1. // Pass engine to Fiber's Views Engine
  2. app := fiber.New(fiber.Config{
  3.     Views: engine,
  4. })

The Render method is linked to the ctx.Render() function that accepts a template name and binding data.

  1. app.Get("/", func(c *fiber.Ctx) error {
  2.     return c.Render("index", fiber.Map{
  3.         "hello": "world",
  4.     });
  5. })

Engines

Fiber team maintains templates package that provides wrappers for multiple template engines:

  1. package main
  3. import (
  4.     "log"
  5.     "github.com/gofiber/fiber/v2"
  6.     "github.com/gofiber/template/html"
  7. )
  9. func main() {
  10.     // Initialize standard Go html template engine
  11.     engine := html.New("./views", ".html")
  13.     app := fiber.New(fiber.Config{
  14.         Views: engine,
  15.     })
  16.     app.Get("/", func(c *fiber.Ctx) error {
  17.         // Render index template
  18.         return c.Render("index", fiber.Map{
  19.             "Title": "Hello, World!",
  20.         })
  21.     })
  23.     log.Fatal(app.Listen(":3000"))
  24. }
  1. <!DOCTYPE html>
  2. <body>
  3.     <h1>{{.Title}}</h1>
  4. </body>
  5. </html>
