ExecuteTemplate

As explained in Learn Go with Pocket-Sized Projects

ExecuteTemplate is a Go template API method that renders a specifically named template with supplied data.

ExecuteTemplate renders a specifically named Go template into a writer with supplied data. It becomes necessary when parsing registers multiple templates and Execute cannot determine which one to run. section 11.5.3 section 11.6

Use ExecuteTemplate when templates are loaded together:

  • Load files with ParseFS; templates are indexed by their base filenames. section 11.5.3
  • Pass the response writer, the registered template name, and the data value. section 11.5.3
  • Use Execute directly only when one parsed template leaves no ambiguity. section 11.5.3

Rendering the embedded index template

err = tpl.ExecuteTemplate(w, "index.html", map[string]interface{}{ "Habits": habits, "Date": week, }) if err != nil { // handle rendering failure } section 11.5.3

How Learn Go with Pocket-Sized Projects covers it

How deep it goes
Explains named selection, base-name registration, arguments, and the single-template case; it stops short of API internals.
Examples
Demonstrates rendering index.html with Habits and Date data through an HTTP response writer.
What it assumes
Assumes familiarity with Go templates and parsing; clarifies how multiple parsed templates require explicit selection.
What you can do after
Operate Go templates by selecting a registered template name and rendering supplied data to a writer.
How it connects
Connects template execution with ParseFS, embedded files, template definitions, and HTTP response writers.
