Generaly speaking, I want to retrieve data from a server without reloading a page. I guess I can write a javascript code with something like get('fiber_api_route/get_data')
and include it in html template. Is there a better way to do is without a need to write js code? The desired way of doing this is to add to html template something like <button onClick=golang_fiber_function!_name>
.
Have a great day

Django engine (pongo2) can not resolve the layout template file with the sample code in this repo. Here's how to reproduce it.
Tested environments
$ git clone --depth=1 [email protected]:gofiber/recipes.git
$ cd recipes/template/
$ go mod vendor && go mod download && go mod tidy
$ cd django/
$ go run main.go
views: [Error (where: fromfile) in ./layouts/main1.html] unable to resolve template

If i changed the first in views/index.html
from {% extends "./layouts/main1.html" %}
to {% extends "./views/layouts/main1.html" %}
, then it works. But since we have django.New("./views", ".html")
in main.go
, isn't it expected that pongo2 looks for files under views/
directory and no need to write this directory name in the extends
tag?
Also, with the modified working template file ({% extends "./views/layouts/main1.html" %}
), it failed with embed
package. Sample code below:
package main
import (
"embed"
"log"
"net/http"
"github.com/gofiber/fiber/v2"
"github.com/gofiber/template/django"
)
//go:embed views/*
var embedDirViews embed.FS
func main() {
// Create a new engine
// engine := django.New("./views", ".html")
engine := django.NewFileSystem(http.FS(embedDirViews), ".html")
// Or from an embedded system
// See github.com/gofiber/embed for examples
// engine := html.NewFileSystem(http.Dir("./views", ".django"))
// Pass the engine to the Views
app := fiber.New(fiber.Config{
Views: engine,
})
app.Get("/", func(c *fiber.Ctx) error {
// Render with and extends
return c.Render("index", fiber.Map{
"Title": "Hello, World!",
})
app.Get("/embed", func(c *fiber.Ctx) error {
// Render index within layouts/main
return c.Render("embed", fiber.Map{
"Title": "Hello, World!",
}, "layouts/main2")
})
log.Fatal(app.Listen(":3000"))
}
No matter how i changed the path in extends
tag, always error like this:
views: [Error (where: fromfile) in ./views/layouts/main1.html] unable to resolve template
When using an embedded http.Filesystem
partials don't use that filesystem, i.e. the partials are not included.
This is due to the following call:
Lines 137 to 138 in 500f0fd
mustache.ParseString
method eventually callsScript data injection seems to be broken:
Go code:
StreetNumber int
StreetName string
}
type User struct {
Name string
Address Address
}
app.Get("/hello", func(c *fiber.Ctx) error {
return c.Render("views/layouts/index", fiber.Map{
"user": User{
Name: "Tom",
Address: Address{
StreetNumber: 10,
StreetName: "Oaks st",
},
},
})
})
Template code:
<script>
var d = {{{ user }}}
console.log(d);
</script>
template output:
<script>
var d = {Tom {%!s(int=10) Oaks st}}
console.log(d);
</script>
Notice how the json is displayed with internal template codes?
Shouldn't this be the json representation of the data?
Hello everyone.
I am trying to add a helper function via AddFunc to the handlebars template engine, but it crashes whenever I use this helper (when loading the page from the browser). I am using GO1.17.2 and the lastest packages (just downloaded them to test).
This is a minimal example case where it still crashes:
package main
import (
"github.com/gofiber/template/handlebars"
"github.com/gofiber/fiber/v2"
"math"
"log"
)
func main() {
templateEngine := handlebars.New("./templates", ".html")
templateEngine.Reload(true)
templateEngine.Debug(true) // prints template names when parsed
templateEngine.AddFunc("getLevelFromXP", func(xp uint) uint {
return uint((-87.5+math.Sqrt(87.5*87.5+50.0*float64(xp)))/25)
})
app := fiber.New(fiber.Config {
Views: templateEngine,
})
app.Get("/", func(c *fiber.Ctx) error {
return c.Render("index", nil)
})
log.Fatal(app.Listen(":3000"))
}
The template simply contains {{getLevelFromXP 1200}}
but it is not parsed because even when the index template is missing I still get the crash.
panic: Helper already registered: getLevelFromXP

Any help is appreciated.
I have structure of my project:
-public
--static
----resources
------css
-------*css files
----templates
-------*html files
don't know how to call my css files like what I do in mux.
Is it possible to parse html files recursive ? Let's say I have this directory structure:
--templates
-------global
-----------header.html
-----------footer.html
-----------navbar.html
-------pages
-----------index.html
-----------about.html
Right now with html.New("./templates", ".html")
It will error with: render: template index does not exist
It would be nice if the html.New would have a recursive option allowing to parse all templates in all subdirectories
๐
Sample code:
package main
import (
"strconv"
"github.com/gofiber/fiber/v2"
"github.com/gofiber/template/jet"
)
func CustomRoute() *fiber.App {
engine := jet.New("./views", ".jet")
route := fiber.New(fiber.Config{
Views: engine,
})
route.Get("/sample", func (c *fiber.Ctx) error {
return c.Render("main", fiber.Map{
"Title": "Hello, World!",
})
})
return route
}
And compile code or use go mod tidy
will get result:
go: github.com/gofiber/[email protected] requires
github.com/cbroglie/[email protected] requires
github.com/golangci/[email protected] requires
github.com/spf13/[email protected] requires

Is anybody have same issue to me?
I have 3 files: index.html, layout.html, and a partial/header.html
Using the django engine:
{% extends "./views/layout.html" %}
{% block content %}
CONTENT

<!DOCTYPE html>
<html>
<body>
{% include "./views/partials/header.html" %}
{% block content %}{% endblock %}

The engine fails with the following error

Some package still uses old logrus (1.2.0, 1.6.0), might be a good idea to update logrus

this works only when the function is passed in via c.Render("", fiber.Map{"Static": ... but not with AddFunc

How to get go variables for layout or partial include files.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>{{.title}}</title> <!-- layouts file how get go variables -->
</head>
<body>
{{embed}}
</body>
</html>
I am writing an app that requires templates and switched to django because handlebars and html templates do not support template inheritance. However <% extends TAG in pongo2 seems to be failing because the baseDir is set to "/" and it uses http.ioFS Open() and that goes to embed.FS Open()... validation fails:
go/src/io/fs/fs.go
// ValidPath reports whether the given path name
// is valid for use in a call to Open.
//
// Path names passed to open are UTF-8-encoded,
// unrooted, slash-separated sequences of path elements, like โx/y/zโ.
// Path names must not contain an element that is โ.โ or โ..โ or the empty string,
// except for the special case that the root directory is named โ.โ.
// Paths must not start or end with a slash: โ/xโ and โx/โ are invalid.
//
// Note that paths are slash-separated on all systems, even Windows.
// Paths containing other characters such as backslash and colon
// are accepted as valid, but those characters must never be
// interpreted by an FS implementation as path element separators.
func ValidPath(name string) bool {
Seems you have fixed the issue:
10138ff
However there is no official release of this fix. TAG?

Hi
I'm in the hunt of a best approach to add assets from build tools like webpack or Vite into the templates.
Most assets are bundled with assets tagged with version e.g index.12345678890.js and is mapped from within the manifest.json file .
And I would like to reference an asset like {{ asset eq "index.js" }} or {{ asset eq "main.css" }} which reads the manifest.json and adds the correct asset to the template .
Dear all,
According to go.sum (line 66), gofiber/template (indirectly) uses few GPL licensed packages, do I understand correctly that if my program uses gofiber/template, then my program must be open sourced under GPL?
gofiber/template (MIT)

github.com/cbroglie/mustache (MIT)

github.com/golangci/golangci-lint (GPL)

Compare the graph of dependent packages with and without github.com/cbroglie/mustache
:
I have a file like this in side of my project root views/index.html
. No matter what I try for a path to render the template I get the error template views/index does not exist
, or something of that nature depending on the path I try passing. I tried the same setup with mustache, and it worked fine.
package main
import (
"embed"
"log"
"net/http"
"github.com/gofiber/fiber/v2"
"github.com/gofiber/template/django"
)
//go:embed views/*
var viewsfs embed.FS
func main() {
engine := django.NewFileSystem(http.FS(viewsfs), ".html")
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, World!",
})
})
log.Fatal(app.Listen(":3000"))
}
I want my layout
to be a template for all my pages. However the
c.Render("index", fiber.Map{
"Title": "Hello, World!",
})
Can only change the content within body
.
I need to change the HTML Title in the header as well.
Any way to do that? thx.
Currently, this project homepage URL is https://docs.gofiber.io/middleware#template but it should be https://docs.gofiber.io/guide/templates
Using the "template/html" package I am having issues rendering templates that derive a base layout all located in the same directory. I have a base layout template like so:
base.html
{{define "base"}}
<!DOCTYPE html>
<html lang="en">
<body>
header...
{{block "content" .}}{{ end }}
footer...
</body>
</html>
{{end}}
a first page like so which renders fine:
first.html
{{ template "base" .}}
{{define "content"}}
Some content
{{end}}
and a second page like so:
second.html
{{ template "base" .}}
{{define "content"}}
Some more content
{{end}}
My template configuration looks as follows:
engine := html.New("./views", ".html")
engine.Reload(true)
app := fiber.New(fiber.Config{
Views: engine,
})
app.Get("/first", func(c *fiber.Ctx) error {
return c.Render("first", fiber.Map{})
})
app.Get("/second", func(c *fiber.Ctx) error {
return c.Render("second", fiber.Map{})
})
The issue I am encountering is that the second page renders the content of the first. Is this expected behavior in this situation? Normally with "template/html" I would call template.ParseFiles("first.html", "base.html")
for the first template and template.ParseFiles("second.html", "base.html")
for the second template. How exactly does Fiber determine which templates to parse based on the single template name? Thanks!
I'm struggled with PUG template using official PUG example like this one:
- var user = {description: 'foo bar baz'}
- var authorised = false
#user
if user.description
h2.green Description
p.description= user.description
else if authorised
h2.blue Description
p.description.
User has no description,
why not add one...
else
h2.red Description
p.description User has no description
I'm getting this error:
template:5: template:9: Error lex: lexClass: expect class name line: 9
Also comparison with ==
operator:
if .someVar== "someValue"
div someVar has someValue
leads to:
template: index:131: unexpected "=" in operand
is there a function that is executed after template rendering?, for example to minify html
Hi! I couldn't find an answer on google or documentation. I want pass template file via variable or function like this:
{% include "./Lumia/partials/primitives/{{Value.GetType()}}.html" with Value=Value only %}
but get error:
views: [Error (where: fromfile) in partials\primitives\{{Value.GetType()}}.html | Line 1 Col 12 near 'partials/primitives/{{Value.GetType()}}.html'] unable to resolve template
Is there any workaround?
Hello Gofiber team,
First of all, thank you all for making a great product.
I have encountered a problem that I believe is very serious with gofiber's html package.
I use the sample of the package at https://github.com/gofiber/template, no problem happens. But when I added the layout path to the first router handle, race conditions occurred.
app.Get("/", func(c *fiber.Ctx) error {
// Render index
return c.Render("index", fiber.Map{
"Title": "Hello, World!",
}, "layouts/main")
})
I use the package https://github.com/tsliwowicz/go-wrk to test. The result is as follows:

How do I fix this problem?
Also, is there a way to define the layout path one time only to avoid re-define it again inside Render function?
Thanks!
The inner "embed" template is correct, but the layout is shown as text in browser.
Demo repository at: https://github.com/jorgefuertes/fiber-tests
Thanks.

It seems that the include syntax is unsupported by pongo2 or there's something wrong with my initialization of the engine?
I did it like this:
engine := django.New("public", ".html"))
I have a public folder like this:
public
-- admin
-- assets
-- layouts
-- partials
-- pub
- admin-index.html
My intention is to separate the admin area templates with actual public templates, does this setup need an embedded filesystem instead of just plain location string?
Hi, I am trying to include partial from a file but seem to have no success.
app := fiber.New()
app.Settings.TemplateEngine = template.Handlebars()
app.Settings.TemplateFolder = "./views"
And in the route I do the following
func consoleDefault(c *fiber.Ctx) {
bind := fiber.Map{
"name": "John",
"age": 35,
}
if err := c.Render("index.hbs", bind); err != nil {
c.Status(500).Send(err.Error())
}
}
My index.hbs includes and renders the name variable currently. But the partial is not working. I have tried with relative paths, with and without extensions and no luck.
I keep getting this error.
I have looked into the Raymond repo and there are no clear examples of how to use it.
Thanks in advance.
On the about section atleast on this middleware there is still a link to the old fiber.wiki page which is not in use anymore.
The fiber.wiki links should be changed with links to the new documentation site (docs.gofiber.io).
Due to a small typo-bug the binding interface{}
passed to the Render
funtion is not used when rendering the layout.
I submitted #85 to fix this.
Hello,
Do you have any plans for supporting EJS?
Thanks.
Why call pongo2 style template django?
The readme for pongo2 says..
pongo2 is a Django-syntax LIKE templating-language.
(emphasis mine)
Since the syntax is not 100% alike I would rather not have to look for what libraries that is actually used for the django like syntax.
Just calling it pongo2 would be much more descriptive but I might have missed something.
Hello, How to get fiber.Ctx in add template(django) function ?
Example:
package main
import (
"log"
"github.com/gofiber/fiber"
"github.com/gofiber/template/html"
)
func Greeting(greeting string) string {
// set default values -- the proper way
if greeting == "" {
greeting = "<p><b>Rocks!</b></p>"
}
return greeting
}
func main() {
// Initialize standard Go html template engine
engine := html.New("./views", ".html")
app := fiber.New(&fiber.Settings{
Views: engine,
})
app.Get("/", func(c *fiber.Ctx) {
// Render index template
_ = c.Render("index", fiber.Map{
"Greetings": Greeting(""),
})
})
// 404 Handler
app.Use(func(c *fiber.Ctx) {
c.SendStatus(404) // => 404 "Not Found"
})
log.Fatal(app.Listen(3000))
}
index.html
<!DOCTYPE html>
<body>
<b>{{.Greetings}}</b>
</body>
</html>
https://github.com/gofiber/template/tree/master/html
Specifically, where it says "click here to preview", it returns a 404 error
I don't quite understand where I went wrong, but it seems quite logical to me. I made a simple copy for you to see, I am sharing the link below. Can someone help me with where I went wrong?
When html engine has Reload(true), then rendering multiple times, it fails with 'html/template: cannot Parse after Execute'.
func Test_HTML_Render_Twice(t *testing.T) {
engine := New("./views", ".html")
engine.Reload(true)
engine.AddFunc("isAdmin", func(user string) bool {
return user == "admin"
})
if err := engine.Load(); err != nil {
t.Fatalf("load: %v\n", err)
}
var buf, buf2 bytes.Buffer
engine.Render(&buf, "index", map[string]interface{}{
"Title": "Hello, World!",
}, "layouts/main")
err := engine.Render(&buf2, "index", map[string]interface{}{
"Title": "Hello, World!",
}, "layouts/main")
if err != nil {
fmt.Println(err.Error())
}
expect := `<!DOCTYPE html><html><head><title>Main</title></head><body><h2>Header</h2><h1>Hello, World!</h1><h2>Footer</h2></body></html>`
result := trim(buf2.String())
if expect != result {
t.Fatalf("Expected:\n%s\nResult:\n%s\n", expect, result)
}
}
The issue is that in jetVarMap
it assumes that a nil binding
should result in a nil jet.VarMap
.
Lines 233 to 237 in c4b2c7e
But if a layout is specified, it is then used to set a function and panics:
Lines 219 to 229 in c4b2c7e
This could be solved either by replacing var bind jet.VarMap
with bind := make(jet.VarMap)
or by checking if bind
is nil (and make
ing it if not) in Render
right after if len(layout) > 0 {
.
// var bind jet.VarMap
bind := make(jet.VarMap)
Or in Render
bind := jetVarMap(binding)
if len(layout) > 0 {
if bind == nil {
bind = make(jet.VarMap)
}
lay, err := e.Templates.GetTemplate(layout[0])
if err != nil {
return err
}
bind.Set(e.layout, func() {
_ = tmpl.Execute(out, bind, nil)
})
return lay.Execute(out, bind, nil)
}
I would send a pull request, but I'm not sure if it matters to you which way it is fixed. I would think it would be much clearer to put it in jetVarMap and get rid of the other calls to make
there, but I guess there was a reason to not do that in the first place.
The work around is for the caller of Render
to just specify an empty jet.VarMap
or fiber.Map
but that is not obvious and panic
ing from forgetting is not great.
I am use Jet template
This not work:
err := c.Render("index", fiber.Map{
"qwe": "Hello, World ๐!",
})
This work:
err := c.Render("index", map[string]interface{}{

})

How do I output specific sections or variable without them being HTML encoded for safety? I understand the implications of doing this and how I'm exposing myself to XSS etc but I have this one specific bit of code that absolutely needs to be outputted untouched. I checked the article linked to in the read me and tried using template.HTML but it doesn't seem to be working.
I appreciate any pointers. Thank you.
