Yesod.Core.Widget

Contents

Description

Widgets combine HTML with JS and CSS dependencies with a unique identifier generator, allowing you to create truly modular HTML components.

Synopsis

Datatype

type WidgetT site (m :: * -> *) = WidgetFor site Source #

Deprecated: Use WidgetFor directly

data WidgetFor site a Source #

A generic widget, allowing specification of both the subsite and master site datatypes. While this is simply a WriterT, we define a newtype for better error messages.
