How can I "compile" an HTML template but not "execute" it?

Question

I'm using Go HTML templates and when you run this function it sends the data to the client, but I would like to store that data in a variable and send it to the client later. How can this be achieved?

func (t *Template) ExecuteTemplate(wr io.Writer, name string, data any) error

This is for use in an AJAX response. I know on the client side I could simply parse the xhr.responseText, but I need to send some other variables with it.

I get an error: `cannot use variable of type bytes.Buffer as io.Writer value in argument to templates.ExecuteTemplate: bytes.Buffer does not implement io.Writer (method Write has pointer receiver).` — hermancain, Sep 09 '22 at 02:06
Hey nevermind I just needed to make the `bytes.Buffer` a pointer. testing now — hermancain, Sep 09 '22 at 02:10

Use a buffer:

buf:=bytes.Buffer{}
t.ExecuteTemplate(&buf,"name",data)

Then you can use buf.Bytes(), or buf.String().
