NATS Subjects
This page provides an overview of NATS subjects used by wasmCloud.
wRPC
NATS Subjects used for wRPC communication adopt the following subject pattern:
plaintext
{lattice}.{component_id}.wrpc.{protocol_version}.{namespace}:{package}/{interface}@{version}.{function}
See RPC page for more details.
Control Interface
The complete Control Interface documentation can be found here, and follows the following pattern:
plaintext
wasmbus.ctl.{version}.{lattice}.{noun}.{verb}.{optional_name}

| wasmbus.ctl.v1.{lattice}.link.del | Link operations | Delete link |
wadm API
The wadm API uses the "model" term for brevity; each model is an individual application manifest. The complete wadm API documentation can be found here takes requests in the following format:
plaintext
wadm.api.{lattice}.{category}.{operation}.{object}
| Subject | Group | Details |
|---|---|---|
| wadm.api.{lattice}.model.put | Models | Store model |
| wadm.api.{lattice}.model.list | Models | List models |
| wadm.api.{lattice}.model.get.{name} | Models | Get model |
| wadm.api.{lattice}.model.versions.{name} | Models | Version history |
| wadm.api.{lattice}.model.del.{name} | Models | Delete model |
| wadm.api.{lattice}.model.deploy.{name} | Deployments | Deploy |
| wadm.api.{lattice}.model.undeploy.{name} | Deployments | Undeploy |
| wadm.api.{lattice}.model.status.{name} | Deployments | Deployment status |
