Concepts

When you ran the hello example in the TypeScript or Python quickstart, you were already using most of Naylence’s core ideas:

• a fabric that routes messages,
• a node that hosts agents and connects to the fabric,
• and at least one agent that receives a message and does something useful.

This section puts names to those pieces so the rest of the docs have a clear vocabulary.

Core Concepts

• Fabric – The messaging layer that connects everything.
• Nodes – The hosts where agents live.
• Agents – The units of logic that send and receive messages.
• Sentinels – Special nodes for routing and security.
• Clients – Code that initiates interactions.

Mapping concepts to the hello examples

Here is how the quickstart examples line up with these concepts:

• Fabric – the object you create at the start of the program; it routes messages to agents.
• Node – the process that created the fabric and registered the agent.
• Agent – the class or function you wrote (HelloAgent) that logs the incoming message.
• No sentinel yet – all of this runs in one process, so there is no separate routing node.

As you read the rest of the docs, you can keep this mental mapping in mind:

• Fabric → the message bus,
• Node → where agents live,
• Agent → a unit of behavior with an address,
• Sentinel → an edge node that routes and protects the fabric.
