The controller imports mesh-host/validate through a replace onto the forge that holds it, and every build — the build agent's go build in a fresh toolchain container, the Dockerfile's go mod download — would have fetched it through the public proxy and checksum database at build time: a merge breaking main on the network, the class Phase 1 removes. vendor/ is committed; go builds from it with nothing fetched, and refuses to build when it and go.mod disagree, so a pin moved without go mod vendor fails at once. The Dockerfile copies vendor/ and builds with GOPROXY=off.

# Legacy JetStream API
|
|
|
|
This is a documentation for the legacy JetStream API. A README for the current
|
|
API can be found [here](jetstream/README.md)
|
|
|
|
## JetStream Basic Usage
|
|
|
|
```go
|
|
import "github.com/nats-io/nats.go"
|
|
|
|
// Connect to NATS
|
|
nc, _ := nats.Connect(nats.DefaultURL)
|
|
|
|
// Create JetStream Context
|
|
js, _ := nc.JetStream(nats.PublishAsyncMaxPending(256))
|
|
|
|
// Simple Stream Publisher
|
|
js.Publish("ORDERS.scratch", []byte("hello"))
|
|
|
|
// Simple Async Stream Publisher
|
|
for i := 0; i < 500; i++ {
|
|
js.PublishAsync("ORDERS.scratch", []byte("hello"))
|
|
}
|
|
select {
|
|
case <-js.PublishAsyncComplete():
|
|
case <-time.After(5 * time.Second):
|
|
fmt.Println("Did not resolve in time")
|
|
}
|
|
|
|
// Simple Async Ephemeral Consumer
|
|
js.Subscribe("ORDERS.*", func(m *nats.Msg) {
|
|
fmt.Printf("Received a JetStream message: %s\n", string(m.Data))
|
|
})
|
|
|
|
// Simple Sync Durable Consumer (optional SubOpts at the end)
|
|
sub, err := js.SubscribeSync("ORDERS.*", nats.Durable("MONITOR"), nats.MaxDeliver(3))
|
|
m, err := sub.NextMsg(timeout)
|
|
|
|
// Simple Pull Consumer
|
|
sub, err := js.PullSubscribe("ORDERS.*", "MONITOR")
|
|
msgs, err := sub.Fetch(10)
|
|
|
|
// Unsubscribe
|
|
sub.Unsubscribe()
|
|
|
|
// Drain
|
|
sub.Drain()
|
|
```
|
|
|
|
## JetStream Basic Management
|
|
|
|
```go
|
|
import "github.com/nats-io/nats.go"
|
|
|
|
// Connect to NATS
|
|
nc, _ := nats.Connect(nats.DefaultURL)
|
|
|
|
// Create JetStream Context
|
|
js, _ := nc.JetStream()
|
|
|
|
// Create a Stream
|
|
js.AddStream(&nats.StreamConfig{
|
|
Name: "ORDERS",
|
|
Subjects: []string{"ORDERS.*"},
|
|
})
|
|
|
|
// Update a Stream
|
|
js.UpdateStream(&nats.StreamConfig{
|
|
Name: "ORDERS",
|
|
MaxBytes: 8,
|
|
})
|
|
|
|
// Create a Consumer
|
|
js.AddConsumer("ORDERS", &nats.ConsumerConfig{
|
|
Durable: "MONITOR",
|
|
})
|
|
|
|
// Delete Consumer
|
|
js.DeleteConsumer("ORDERS", "MONITOR")
|
|
|
|
// Delete Stream
|
|
js.DeleteStream("ORDERS")
|
|
```
