Browser Cloud Watch Support

Hi All

I was really excited to use this in my project which is based on create-react-app. After installing and including in my error handler I realized that this module seems to be pretty squarely designed for server-side nodejs projects.

I got all sorts of errors like this: Can't resolve 'dns' in '/home/app/frontend/node_modules/pac-resolver which clued me into the fact this doesn't seem to be working for client side javascript or create-react-app projects.

It looks like Winston was also not really designed for browser support originally either but recently in V3 they made this possible (https://github.com/winstonjs/winston/issues/287). I've had success making it work with the Console driver. My plan was to use this CloudWatch driver for production.

If anyone knows how to make this work with a client side JS app or if there's plans to make it compatible for that platform, that would be great to hear or find out about.

Hi @drmmr763, I don't have plans to support client side at the moment. I am open to suggestions or PRs though.

If anyone is looking for this, I came across this issue and was the first result on Google so I tough better share what I have done.

In order to get it work I simply used a custom instance of CloudWatchLogs as following:

winston.add(new WinstonCloudWatch({
        cloudWatchLogs: new AWS.CloudWatchLogs({
          region: AwsConfig.Logging.awsRegion, 
          credentials: {
            accessKeyId: "something from a secure location",
            secretAccessKey: "something from a secure location"
          }
        }),
        ...AwsConfig.Logging
      }));

In my case I also created a very strict policy so that FE can only add logs no more, what to do there really depends on your use-case.

In terms of modules version:

• winston: 3.7.2
• winston-cloudwatch: 6.0.1
• @aws-sdk/client-cloudwatch-logs: 3.100.0
