LowNode

LowNodes are the flexible building blocks of your application. They can respond to a route request, or they can be called by another node. They can render a return value, or they can create an event. They are designed to be specific enough to observe events and return values, but generic enough to be split up to represent a complex application with its own patterns and structure. Nodes can render HTML/JSON directly from the Ruby class (via RBX, similar to JSX) and render other nodes into the output using Raindeer's special Antlers syntax; <html><{ ChildNode }></html>.

RBX [UNRELEASED]

Use .rbx as your file extension and now you can place HTML inside of render():

def render
  <html>Content</html>
end

Antlers expressions are also now accepted:

def render
  <html><{ ChildNode }></html>
end

Slots
