Why can't Go, html/template, and Fiber collaborate to compose templates?

I want to render a template using a base template and one of two partial templates, based on the context. Something like:

Patial A Base Template |────────────| |───────────────| |───────────────| | | | | | | | AAAAAAAA | componse with | {{ .Target }} | to yield | AAAAAAAA | | | | | | | |────────────| |───────────────| |───────────────| Patial A Base Template |────────────| |───────────────| |───────────────| | | | | | | | BBBBBBBB | componse with | {{ .Target }} | to yield | BBBBBBBB | | | | | | | |────────────| |───────────────| |───────────────|

I constructed an experiement using the following folder structure, templates, and logic

Folder Structure

templates/ │ ├── main.go └── view/ ├── base.html ├── partailA.html ├── partailB.html

Templates

I used the html/template define and block and layout actions:

{{ define "base" .}} <!-- This is the base template --> <div> <!-- insert particl template here --> {{ block "partial" . }}{{ end }} </div> {{ end }}

These are the partial templates:

**{{ define "partial" }}** <!-- This is a partical template --> <div> <p>Partial Template A</p> </div> {{ end }} {{ define "partial"}} <!-- This is another template --> <div> <p>Partial Template B</p> </div> {{ end }}

Logic

package main import ( "log" "github.com/gofiber/fiber/v2" "github.com/gofiber/template/html/v2" ) const ( ADMIN = "admin" ) var LayoutDir string = "views/layouts" var bootstrap *template.Template func main() { var err error // Create a new engine engine := html.New("./views", ".html") // Pass the engine to the Views app := fiber.New(fiber.Config{ Views: engine, }) app.Static("/", "./public") app.Get("/patialA", func(c *fiber.Ctx) error { // Render index return c.Render("partialA", fiber.Map{}, "base") }) app.Get("/patialB", func(c *fiber.Ctx) error { // Render index return c.Render("partialB", fiber.Map{}, "base") }) log.Fatal(app.Listen(":3000")) }

After trying all kinds of suggestions, including from ChatGPT, I gave up on the Go, html/template, and Fiber stack, switched to Go, html/template, and Gin, and made it work.

Regardless, I'm still curious about whether there is a way to make it work with Fiber.
