Nodes

A node is a host for agents.

A node:

• runs in a particular runtime (Python, Node.js, browser, etc.),
• connects to a fabric (normally through a sentinel),
• registers agents and gives them addresses,
• and handles I/O and lifecycle for those agents.

In the hello example:

• You effectively had one node: the process that created the fabric and the agent.
• The node, fabric, and agent all lived in the same process, so there was no network in between.

In distributed setups, you will see:

• one or more agent nodes (backend services, workers, browser clients),
• a sentinel node that acts as a front door and router between them.

You can think of a node as “a place where agents live”. A fabric may connect many nodes together.
