log-aws-lambda

log writer for AWS Lambda environment

Printf-like message formatting
Configure log level visbility threshold through LOG_LEVEL env variable (defaults to notice)
Extra debug output can be controlled via LOG_DEBUG env variable (fallbacks to DEBUG if provided)
Object inspection depth defaults to 4, but can be overriden via LOG_INSPECT_DEPTH (fallbacks to DEBUG_DEPTH if provided)
Writes logs via console.error (not process.stderr) to ensure logs are accompanied in CloudWatch by AWS prefixes

At beginning of main module of your program invoke:

require("log-aws-lambda")();

Note: Value of LOG_TIME env var is ignored, as AWS logs by default are accompanied with absolute timestamps
