Types

Introduction

This is a collection of types (structs) that the components use as input arguments. We’re using structs as they provide a convenient way to pass default values to the components; struct fields initialize to the respective type’s default value. We can use this feature to make some of the fields of a struct optional. For example, we can pass the model.Anchor argument to an anchor element, <a>:

templ Anchor(anchor model.Anchor) {
    <a
        if anchor.Href != "" {
            href={ anchor.Href }
        }
        { anchor.Attrs... }
    >
        if anchor.Icon != nil {
            @anchor.Icon
        }
        { anchor.Label }
    </a>
}

Here we can define the anchor element to optinally have an href attribute, or if we choose, a hx-get instead:

@Anchor(model.Anchor{Href: "/"})
@Anchor(model.Anchor{Attrs: templ.Attributes{"hx-get": "/"}})

The types

You can place these types in a file e.g. internal/model/components.go for easily accessing the correct type for each component.
