Views
You can use ERB-like built-in ECR views to render files.
get '/:name' do
render "views/hello.ecr"
end
And you should have an hello.ecr view. It will have the same context as the method.
Hello <%= env.params["name"] %>
Using Layouts
You can use layouts in Kemal. You should pass a second argument.
get '/:name' do
render "views/subview.ecr", "views/layouts/layout.ecr"
end
And you should use content variable (like yield in Rails) in layout file.
<html>
<head>
<title><%= $title %></title>
</head>
<body>
<%= content %>
</body>
</html>
Using Common Paths
Since Crystal does not allow using variables in macro literals, you need to generate another helper macro to make the code easier to read and write.
macro my_renderer(filename)
render "my/app/view/base/path/#{{{filename}}}.ecr", "my/app/view/base/path/layouts/layout.ecr"
end
And now you can use your new renderer.
get '/:name' do
my_renderer "subview"
end
