Middy middleware wrapper for lesslog
The middleware registers before
, after
and onError
handlers to log the incoming event, outgoing response or thrown error respectively.
Using lesslog
however this debug information will not be logged immediately, but buffered internally. Once an error is thrown any buffered logs will be emitted, preserving their original timestamp and context. No debug information is lost, while still maintaining clutter-free logs the rest of the time. You can learn more about how lesslog
processes your logs by reading its documentation.
$ npm install lesslog middy-lesslog
Note: lesslog
is a peer dependency of middy-lesslog
.
import middy from '@middy/core'
import log from 'middy-lesslog'
async function handler(event, context) {
// Do something meaningful
return {
statusCode: 200,
}
}
export const handler = middy(handler).use(log())
There are no configuration options so far. Reach out or open an issue, if you want to see a specific option to be configurable!
If the DEBUG
environment variable is set to either '1'
, 'on'
, 'true'
, or 'yes'
, the incoming event and outgoing response will not be buffered internally, but instead directly written to process.env.stdout
. This behavior is built-in to lesslog
.
