A Winston transport for Amazon CloudWatch.
npm install winston-aws-cloudwatch    
A Winston transport for
Amazon CloudWatch.
``js
const winston = require('winston')
const CloudWatchTransport = require('winston-aws-cloudwatch')
const logger = winston.createLogger({
transports: [
new CloudWatchTransport({
logGroupName: '...', // REQUIRED
logStreamName: '...', // REQUIRED
createLogGroup: true,
createLogStream: true,
submissionInterval: 2000,
submissionRetryCount: 1,
batchSize: 20,
awsConfig: {
accessKeyId: '...',
secretAccessKey: '...',
region: '...'
},
formatLog: item =>
${item.level}: ${item.message} ${JSON.stringify(item.meta)}
})
]
})
If, for any reason, logging to CloudWatch should fail, then the transport will
emit an error` event. It is recommended that you
subscribe to this event
to avoid crashes.
As you may have noticed, there is also
winston-cloudwatch, which
predates this module. After making some contributions to that one, I felt like
writing my own version. Feel free to use whichever you like best.
