 # dda-masto-embed
 Embeds mastodon timline into a html page. Uses JS, no intermediate server required.
+
+
+# Setup
+
+To setup a basic luminus project:
+* lein new luminus shipping-cljs +kee-frame
+
+Start a leiningen repl and run fighwheel and let it connect to your application:
+
+1) lein repl
+    * user=> (start)
+2) lein figwheel
+3) Open http://localhost:3000/ in Browser
+4) figwheel should have connected to your application
+
+# Development
+
+lein repl does not seem to work with clojurescript. Lein figwheel is needed to work with clojurescript. 
+
+E.g. in your figwheel repl:
+
+
+
+app:cljs.user=> (in-ns 'masto-embed.routing)
+app:masto-embed.routing=> routes
+
+But will lead to Unable to resolve symbol: routes in this context
+in lein repl.

+<h1 class="title">Congratulations, your <a class="alert-link" href="http://luminusweb.net">Luminus</a> site is ready!</h1>
+
+This page will help guide you through the first steps of building your site.
+
+<p class="title is-5">Why are you seeing this page?</p>
+
+The `home-routes` handler in the `masto-embed.routes.home` namespace
+defines the route that invokes the `home-page` function whenever an HTTP
+request is made to the `/` URI using the `GET` method.
+
+```
+(defroutes home-routes
+  (GET "/" []
+       (home-page))
+  (GET "/docs" []
+       (-> (response/ok (-> "docs/docs.md" io/resource slurp))
+           (response/header "Content-Type" "text/plain; charset=utf-8"))))
+```
+
+The `home-page` function will in turn call the `masto-embed.layout/render` function
+to render the HTML content:
+
+```
+(defn home-page []
+  (layout/render "home.html"))
+```
+
+The page contains a link to the compiled ClojureScript found in the `target/cljsbuild/public` folder:
+
+```
+{% script "/js/app.js" %}
+```
+
+The rest of this page is rendered by ClojureScript found in the `src/cljs/masto_embed/core.cljs` file.
+
+
+
+<p class="title is-5">Organizing the routes</p>
+
+The routes are aggregated and wrapped with middleware in the `masto-embed.handler` namespace:
+
+```
+(defstate app
+  :start
+  (middleware/wrap-base
+    (routes
+      (-> #'home-routes
+          (wrap-routes middleware/wrap-csrf)
+          (wrap-routes middleware/wrap-formats))
+      (route/not-found
+        (:body
+          (error-page {:status 404
+                       :title "page not found"}))))))
+```
+
+The `app` definition groups all the routes in the application into a single handler.
+A default route group is added to handle the `404` case.
+
+<a class="level-item button" href="http://www.luminusweb.net/docs/routes.md">learn more about routing »</a>
+
+The `home-routes` are wrapped with two middleware functions. The first enables CSRF protection.
+The second takes care of serializing and deserializing various encoding formats, such as JSON.
+
+<p class="title is-5">Managing your middleware</p>
+
+Request middleware functions are located under the `masto-embed.middleware` namespace.
+
+This namespace is reserved for any custom middleware for the application. Some default middleware is
+already defined here. The middleware is assembled in the `wrap-base` function.
+
+Middleware used for development is placed in the `masto-embed.dev-middleware` namespace found in
+the `env/dev/clj/` source path.
