Use xtemplate for nested templating
Here the example when I use xtemplate alongside with go-fiber.
Why I use xtemplate if go-fiber already created official html templating with nested feature? This pattern is currently what I'm familiar with. So, for now, I have no issue to keep using it.
But this might not comply with your project needs.
package helpers import ( "github.com/dannyvankooten/extemplate" "github.com/gofiber/fiber/v2" ) // Init var xt = extemplate.New() // we only need call this once. func ParseTemplateWithinDir(viewDir string) error { return xt.ParseDir(viewDir, []string{".html"}) } // Render the targeted template func RenderTemplateWithContext(c *fiber.Ctx, viewDir, name string, data map[string]interface{}) error { // In development phase, I want to make it re-parsing the template every time my app render the pages. // this is Opt-in. And we can disabled it in production env. err := ParseTemplateWithinDir(viewDir) if err != nil { return err } // Execute the template. return xt.ExecuteTemplate(c.Response().BodyWriter(), name, data) } // helper to ensure the response is HTML func UseHtml(c *fiber.Ctx) { c.Response().Header.Add("Content-Type", "text/html; charset=utf-8") } Create the templates
File views/base.html

Last, render the template.
