AVAILABLE TO CREATE APPS; • FETCH DEPENDENCIES; • COMPILE; • START SERVER. CREATING A NEW APP

• ROUTES; • CONTROLLERS; • VIEWS; • TEMPLATES; • CHANNELS.
LET'S SEE WHAT WE GOT

ROUTES

get “/pages/:slug”, PageController, :show # GET /pages/about # [“pages”, “about”]
def match(conn, “GET”, [“pages”, slug]) do Controller.peform_action(conn, PageController, :show, slug: slug) end get “/files/*path”, FileController, :show # GET /files/Users/pedro/Documents # [“files”, “Users”, “pedro”, “Documents"] def match(conn, “GET”, [“files” | path]) do Controller.peform_action(conn, FileController, :show, path: path) end ROUTES
