The credentials are already handled transparently - what's the use case for explicitly not setting them? |
I'm working on a project that runs nats as a message bus in k8s cluster that doesn't use username / password auth. I can't use this test container because projects library doesn't expect username and password to be provided. |

+1, we use nats with TLS. In unit tests we'd like to disable auth entirely. If we use username+password we'd have to introduce a variant into the NATS client code solely to use the test container which is not ideal. |

Pull Request Overview
This PR enables starting a NATS server container without credentials, which is a valid NATS configuration. It adds a method to control whether credentials are used during container startup.

withCredentials(boolean)method to enable/disable credential usage - Modified container startup to conditionally pass credentials to the started container

[nitpick] The conditional logic could be simplified by using a ternary operator for better readability: this.useCredentials ? this.getPass() : undefined
| (this.useCredentials && this.getUser()) || undefined, | |

@george-of-croton Need to handle this scenario:
const container = await
.withUsername("x")
.withUsername("y")
.withCredentialsEnabled(true)
.start()
container.getUser(); // test
container.getPass(); // test

it's valid to connect to nats with no username or password. This PR adds a method to remove credential flags on startup.
