Connection Name

Connections can be assigned a name which will appear in some of the server monitoring data. This name is not required, but is highly recommended as a friendly connection name will help in monitoring, error reporting, debugging, and testing.

Go
Java
JavaScript
Python
Ruby
TypeScript

Go
nc, err := nats.Connect("demo.nats.io", nats.Name("API Name Option Example"))
if err != nil {
log.Fatal(err)
}
defer nc.Close()
// Do something with the connection
Java
Options options = new Options.Builder().
server("nats://demo.nats.io:4222").
connectionName("API Name Option Example"). // Set Name
build();
Connection nc = Nats.connect(options);
// Do something with the connection
nc.close();
JavaScript
let nc = NATS.connect({
url: "nats://demo.nats.io:4222",
name: "API Name Option Example"
});
nc.on('connect', (c) => {
// Do something with the connection
doSomething();
// When done close it
nc.close();
});
nc.on('error', (err) => {
failed(err);
});
Python
nc = NATS()
await nc.connect(
servers=["nats://demo.nats.io:4222"],
name="API Name Option Example")
# Do something with the connection
await nc.close()
Ruby
require 'nats/client'
NATS.start(servers: ["nats://demo.nats.io:4222"], name: "API Name Option Example") do |nc|
# Do something with the connection
# Close the connection
nc.close
end
TypeScript
// will throw an exception if connection fails
let nc = await connect({
url:"nats://demo.nats.io:4222",
name: "API Name Option Example"
})
// Do something with the connection
// Close the connection
nc.close();
