Simple CloudWatch Logger

I wrote this because I do this sort of thing over and over. This module makes it easy (for me) to include this behaviour in many of my stack components.

Usage

const log = require( 'node-cwlogger' )( config );
log.info( 'Here we go!' );
log.error( new Error( 'you can not do that here!' ) );
log.debug( "No you don't!", err );
throw( "you gotta a problem" );

Configuration

const config = {
  includeNodeEnv: true,
  console: {
    enabled: true,
    level: 'error',
    colorize: true
  },
  cloudwatch: {
    enabled: true,
    level: 'debug',
    awsAccessKeyId: 'your key',
    awsSecretKey: 'your secret',
    awsRegion: 'your region',
    group: 'cloud watch group name',
    stream: 'cloud watch stream name'
  }
}

The AWS credentials will default (if not specified) to these environment variables:

• AWS_ACCESS_KEY_ID
• AWS_SECRET_KEY
• AWS_REGION

The CloudWatch group will default to process.env.NODE_ENV if not specified. The stream name is required, and would probably be the name of the application. The idea is to group multiple applications under their stack, so you can use something like awslogs and get logs like this to mix all of the apps in the stack together:

awslogs get staging ALL --start='1d ago' --timestamp --profile aws-profile-name

or to get just one app:

awslogs get staging "webserver*" --start='1d ago' --timestamp --profile aws-profile-name
