Yesod—a modern framework for blazing fast websites

Fast, stable & spiced with great community Read the Book

Starting

Now that you have a working project you should use the Yesod book to learn more.

You can also use this scaffolded site to explore some concepts, and best practices.

• This page was generated by the #{handlerName} handler in Handler/Home.hs.
• The #{handlerName} handler is set to generate your site's home screen in the Routes file config/routes.yesodroutes
• We can link to other handlers, like the Comment.
• The HTML you are seeing now is actually composed by a number of widgets, # most of them are brought together by the defaultLayout function which # is defined in the Foundation.hs module, and used by #{handlerName}. # All the files for templates and widgets are in templates.
• A Widget's Html, Css and Javascript are separated in three files with the .hamlet, .lucius and .julius extensions.
• If you had javascript enabled then you wouldn't be seeing this.

  Forms

  This is an example of a form. Read the Forms chapter # in the yesod book to learn more about them.

  ^{formWidget} Upload it!

  $maybe (FileForm info con) <- submission Your file type is #{fileContentType info}. You say it has: #{con} $nothing File upload result will be here...

  JSON

  Yesod has JSON support baked-in. The form below makes an AJAX request with Javascript, then updates the page with your submission. (see Handler/Comment.hs, templates/homepage.julius, and Handler/Home.hs for the implementation).

  Create comment

  Your comments will appear here. You can also open the console log to see the raw response from the server.

  Testing

  And last but not least, Testing. In test/Spec.hs you will find a # test suite that performs tests on this page.

  You can run your tests by doing: stack test
