Disabling Reconnect

You can disable automatic reconnect with connection options:

Go
Java
JavaScript
Python
Ruby
TypeScript
Go
// Disable reconnect attempts
nc, err := nats.Connect("demo.nats.io", nats.NoReconnect())
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").
noReconnect(). // Disable reconnect attempts
build();
Connection nc = Nats.connect(options);
// Do something with the connection
nc.close();
JavaScript
llet nc = NATS.connect({
reconnect: false,
servers: ["nats://demo.nats.io:4222"]
});
Python
nc = NATS()
await nc.connect(
servers=[
"nats://demo.nats.io:1222",
"nats://demo.nats.io:1223",
"nats://demo.nats.io:1224"
],
allow_reconnect=False,
)
# Do something with the connection
await nc.close()
Ruby
require 'nats/client'
NATS.start(servers: ["nats://127.0.0.1:1222", "nats://127.0.0.1:1223", "nats://127.0.0.1:1224"], reconnect: false) 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({
reconnect: false,
servers: ["nats://demo.nats.io:4222"]
});
nc.close();
