Core

Arbor is built from a small set of primitives. Each one is explicit and predictable, and together they define how an application receives a request, processes it and produces a response.

The Core section explains these pieces in isolation so you can understand how Arbor behaves under load, how branching works, and how actions control flow.

Topics in this section:

• Branches
• Routes
• Actions
• Request Bundle
• Body
• Renderers
• Errors
• Static Files

Each concept has its own page. You can read them in any order, but starting with Branches is the most natural introduction to how Arbor structures applications.
