We're going to write a very simple AJAX application. It will be a simple site with a few pages and a navbar; when you have Javascript, clicking on the links will load the pages via AJAX. Otherwise, it will use static HTML.

- -

We're going to use jQuery for the Javascript, though anything would work just fine. Also, the AJAX responses will be served as JSON. Let's get started.

- -> {-# LANGUAGE TypeFamilies, QuasiQuotes, TemplateHaskell, MultiParamTypeClasses, OverloadedStrings #-} -> import Yesod -> import Yesod.Static -> import Data.Text (Text, unpack) - -Like the blog example, we'll define some data first. - -> data Page = Page -> { pageName :: Text -> , pageSlug :: Text -> , pageContent :: Text -> } - -> loadPages :: IO [Page] -> loadPages = return -> [ Page "Page 1" "page-1" "My first page" -> , Page "Page 2" "page-2" "My second page" -> , Page "Page 3" "page-3" "My third page" -> ] - -> data Ajax = Ajax -> { ajaxPages :: [Page] -> , ajaxStatic :: Static -> } - -Next we'll generate a function for each file in our static folder. This way, we get a compiler warning when trying to using a file which does not exist. - -> staticFiles "static/yesod/ajax" - -Now the routes; we'll have a homepage, a pattern for the pages, and use a static subsite for the Javascript and CSS files. - -> mkYesod "Ajax" [parseRoutes| -> / HomeR GET -> /page/#Text PageR GET -> /static StaticR Static ajaxStatic -> |] - -

That third line there is the syntax for a subsite: Static is the datatype for the subsite argument; siteStatic returns the site itself (parse, render and dispatch functions); and ajaxStatic gets the subsite argument from the master argument.

- -

Now, we'll define the Yesod instance. We'll still use a dummy approot value, but we're also going to define a default layout.

- -> instance Yesod Ajax where -> approot _ = "" -> defaultLayout widget = do -> Ajax pages _ <- getYesod -> content <- widgetToPageContent widget -> hamletToRepHtml [hamlet| -> \ -> -> -> -> #{pageTitle content} -> <link rel="stylesheet" href="@{StaticR style_css}"> -> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"> -> <script src="@{StaticR script_js}"> -> \^{pageHead content} -> <body> -> <ul id="navbar"> -> $forall page <- pages -> <li> -> <a href="@{PageR (pageSlug page)}">#{pageName page} -> <div id="content"> -> \^{pageBody content} -> |] - -<p>The Hamlet template refers to style_css and style_js; these were generated by the call to staticFiles above. There's nothing Yesod-specific about the <a href="/static/yesod/ajax/style.css">style.css</a> and <a href="/static/yesod/ajax/script.js">script.js</a> files, so I won't describe them here.</p> - -<p>Now we need our handler functions. We'll have the homepage simply redirect to the first page, so:</p> - -> getHomeR :: Handler () -> getHomeR = do -> Ajax pages _ <- getYesod -> let first = head pages -> redirect RedirectTemporary $ PageR $ pageSlug first - -And now the cool part: a handler that returns either HTML or JSON data, depending on the request headers. - -> getPageR :: Text -> Handler RepHtmlJson -> getPageR slug = do -> Ajax pages _ <- getYesod -> case filter (\e -> pageSlug e == slug) pages of -> [] -> notFound -> page:_ -> defaultLayoutJson (do -> setTitle $ toHtml $ pageName page -> addHamlet $ html page -> ) (json page) -> where -> html page = [hamlet| -> <h1>#{pageName page} -> <article>#{pageContent page} -> |] -> json page = jsonMap -> [ ("name", jsonScalar $ unpack $ pageName page) -> , ("content", jsonScalar $ unpack $ pageContent page) -> ] - -<p>We first try and find the appropriate Page, returning a 404 if it's not there. We then use the applyLayoutJson function, which is really the heart of this example. It allows you an easy way to create responses that will be either HTML or JSON, and which use the default layout in the HTML responses. It takes four arguments: 1) the title of the HTML page, 2) some value, 3) a function from that value to a Hamlet value, and 4) a function from that value to a Json value.</p> - -<p>Under the scenes, the Json monad is really just using the Hamlet monad, so it gets all of the benefits thereof, namely interleaved IO and enumerator output. It is pretty straight-forward to generate JSON output by using the three functions jsonMap, jsonList and jsonMap. One thing to note: the input to jsonScalar must be HtmlContent; this helps avoid cross-site scripting attacks, by ensuring that any HTML entities will be escaped.</p> - -<p>And now our typical main function. We need two parameters to build our Ajax value: the pages, and the static loader.

Basically every Yesod application will start off like this:</p> - -> {-# LANGUAGE TypeFamilies, QuasiQuotes, TemplateHaskell, MultiParamTypeClasses, OverloadedStrings #-} -> import Yesod - -Next, we'll define the blog entry information. Usually, we would want to store the data in a database and allow users to modify them, but we'll simplify for the moment. - -> data Entry = Entry -> { entryTitle :: String -> , entrySlug :: String -- ^ used in the URL -> , entryContent :: String -> } - -Since normally you'll need to perform an IO action to load up your entries from a database, we'll define the loadEntries function to be in the IO monad. - -> loadEntries :: IO [Entry] -> loadEntries = return -> [ Entry "Entry 1" "entry-1" "My first entry" -> , Entry "Entry 2" "entry-2" "My second entry" -> , Entry "Entry 3" "entry-3" "My third entry" -> ] - -Each Yesod application needs to define the site argument. You can use this for storing anything that should be loaded before running your application. For example, you might store a database connection there. In our case, we'll store our list of entries. - -> data Blog = Blog { blogEntries :: [Entry] } - -Now we use the first "magical" Yesod set of functions: mkYesod and parseRoutes. If you want to see *exactly* what they do, look at their Haddock docs. For now, we'll try to keep this tutorial simple: - -> mkYesod "Blog" [parseRoutes| -> / HomeR GET -> /entry/#String EntryR GET -> |] - -Usually, the next thing you want to do after a call to mkYesod is to create an instance of Yesod. Every Yesod app needs this; it is a centralized place to define some settings. All settings but approot have sensible defaults. In general, you should put in a valid, fully-qualified URL for your approot, but you can sometimes get away with just doing this: - -> instance Yesod Blog where approot _ = "" - -This only works if you application is being served from the root of your webserver, and if you never use features like sitemaps and atom feeds that need absolute URLs. - -We defined two resource patterns for our blog: the homepage, and the page for each entry. For each of these, we are allowing only the GET request method. For the homepage, we want to simply redirect to the most recent entry, so we'll use: - -> getHomeR :: Handler () -> getHomeR = do -> Blog entries <- getYesod -> let newest = last entries -> redirect RedirectTemporary $ EntryR $ entrySlug newest - -We go ahead and send a 302 redirect request to the entry resource. Notice how we at no point need to construct a String to redirect to; this is the beauty of type-safe URLs. - -Next we'll define a template for entry pages. Normally, I tend to just define them within the handler function, but it's easier to follow if they're separate. Also for clarity, I'll define a datatype for the template arguments. It would also be possible to simply use the Entry datatype with some filter functions, but I'll save that for a later tutorial. - -> data TemplateArgs = TemplateArgs -> { templateTitle :: Html -> , templateContent :: Html -> , templateNavbar :: [Nav] -> } - -The Nav datatype will contain navigation information (ie, the URL and title) of each entry. - -> data Nav = Nav -> { navUrl :: Route Blog -> , navTitle :: Html -> } - -And now the template itself: - -> entryTemplate :: TemplateArgs -> HtmlUrl (Route Blog) -> entryTemplate args = [hamlet| -> !!! -> <html> -> <head> -> <title>#{templateTitle args} -> <body> -> <h1>Yesod Sample Blog -> <h2>#{templateTitle args} -> <ul id="nav"> -> $forall nav <- templateNavbar args -> <li> -> <a href="@{navUrl nav}">#{navTitle nav} -> <div id="content"> -> \#{templateContent args} -> |] - -Hopefully, that is fairly easy to follow; if not, please review the Hamlet documentation. Just remember that dollar signs mean Html variables, and at signs mean URLs. - -Finally, the entry route handler: - -> getEntryR :: String -> Handler RepHtml -> getEntryR slug = do -> Blog entries <- getYesod -> case filter (\e -> entrySlug e == slug) entries of -> [] -> notFound -> (entry:_) -> do -> let nav = reverse $ map toNav entries -> let tempArgs = TemplateArgs -> { templateTitle = toHtml $ entryTitle entry -> , templateContent = toHtml $ entryContent entry -> , templateNavbar = nav -> } -> hamletToRepHtml $ entryTemplate tempArgs -> where -> toNav :: Entry -> Nav -> toNav e = Nav -> { navUrl = EntryR $ entrySlug e -> , navTitle = toHtml $ entryTitle e -> } - -All that's left now is the main function.
