There's no documentation on how to refresh/update the credentials.

Hi. I'm using this library in a React project to have the ability to subscribe to events. I use the cognito identity method on the browser side to get credentials. It was very simple to do in v1 but now I'm trying to upgrade to v2. In v1 I could do updateWebSocketCredentials to update the credentials, but I can't find anything similar in v2.

I've tried various methods in v2, such as using new_with_websockets that accepts options:

let config = iot.AwsIotMqttConnectionConfigBuilder.new_with_websockets({
    region: awsConfiguration.region,
    service: "wss",
    credentials_provider: {
      getCredentialsAsync: async () => {
        const credentials: any = await getCredentialsAsync();
        if (credentials) {
          expiration = credentials.Expiration;
          return {
            accessKeyId: credentials.AccessKeyId,
            secretAccessKey: credentials.SecretKey,
            sessionToken: credentials.SessionToken,
            expiration: credentials.Expiration,
          };
        }
        return null;
      },
    },
  })

But that doesn't seem to work.

Is there no method to update the credentials when they expire? I found one React example that uses something called .with_credential_provider that doesn't seem to exist any longer.

aws-iot-device-sdk-js-v2/samples/browser/react_sample/src/PubSub.tsx

Line 85 in d81d499

.with_credential_provider(provider)

Any help would be appreciated.

with_credentials_provider hasn't gone anywhere as far as I know: https://github.com/awslabs/aws-crt-nodejs/blob/main/lib/browser/aws_iot.ts#L239

The .with_credential_provider(provider) option does still exist and the current sample in main still uses it.

And to refresh the credentials you just need to call refreshCredentials(). You can find that in the api docs here

There should be no need to refresh the credentials if the sample pattern is followed. A recurrent task does it for you:

Thanks for the quick response @bretambrose

when I try to use .with_credential_provider(provider)

I get: Property 'with_credential_provider' does not exist on type 'AwsIotMqttConnectionConfigBuilder'.

I'm on aws-iot-device-sdk-v2 version 1.19.0 and aws-sdk 2.1541.0. Any clue what could be going on?

If I check the definition of with_endpoint, then I find it in /node_modules/aws-crt/dist/native/aws_iot.d.ts - but I see no presence of with_credential_provider in there.

Oh I figured out the issue. I forgot to set up the path in tsconfig.json. Sorry & thanks for the help. I highly recommend updating README with more details on browser usage.

You're somehow ending up with the node source and not the browser source. If you're using typescript you can ok, you figured it out (https://github.com/aws/aws-iot-device-sdk-js-v2/blob/main/samples/browser/react_sample/tsconfig.json#L16)

I agree, we should put a section in both aws-crt-nodejs and this repo as well.
