I want to make something like a UI component 100% reusable in Go templates but i don't know if it's possible to do it. So I'm trying to do the next:
{{define "components/menu-button"}}
<a href="{{.link}}" class="text-white">{{.content}}</a>
{{end}}
This is my component, it expect a map because of the properties are in lowercase.
And then in my homepage I have this little menu that uses 3 times the components/menu-button component in my navbar:
<div class="hidden gap-4 sm:flex">
{{template "components/menu-button" {"link": "/contact", "content": "Contact"}}}
{{template "components/menu-button" {"link": "/docs", "content": "Docs"}}}
{{template "components/menu-button" {"link": "/download", "content": "Download"}}}
</div>
But I don't know if I can in some way create a map like I'm doing up here in the example, it's like JSON thing but well I tried.
By the way, it gives me the next error:
unexpected "{" in template clause
That kind of syntax is not supported by Go's templates.
What you can do is declare a custom function, e.g.
func MakeMap(kvs ...any) map[any]any {
m := make(map[any]any)
for i := 0; i < len(kvs)-1; i+=2 {
m[kvs[i]] = kvs[i+1]
}
return m
}
Then you can make the function available to the templates by using (*Template).Funcs, e.g.
t.Funcs(template.FuncMap{"M":MakeMap})
Then, inside the template, you can invoke the function using the key M.
{{template "components/menu-button" (M "link" "/contact" "content" "Contact")}}
