nats

Overview ¶

Package nats provides the NATS event-bus Provider implementation. It emits typed IaC resource declarations for supported deploy targets.

Activated targets for the BMW pilot:

• digitalocean.app_platform (TargetDigitalOceanApp) — fully implemented.

Stub targets (not yet activated, return ErrNotImplemented-style errors):

• aws.ecs — deploy_aws_ecs.go
• aws.eks — deploy_aws_eks.go
• kubernetes — deploy_kubernetes.go

Package nats — providers.RuntimeBroker implementation backed by nats-go.

This file holds the NATS-specific publish/subscribe/ensure logic as a single Provider-shaped struct that satisfies the providers.RuntimeBroker contract. Step factories (steps/*.go) and the trigger module (trigger.go) dispatch through this RuntimeBroker via LookupRuntimeWithFallback + providers.RuntimeBroker so they never reach into nats-go directly.

URL resolution: ClusterConfig.dsn is the canonical connection string for every provider — Postgres DSN for pgchannel, NATS URL for nats. See the proto comment on ClusterConfig.dsn for the full per-provider semantics. The runtime layer therefore reads cfg.Dsn unconditionally as the broker URL; no provider-specific field switch is required.
