How to log correctly in node?

Question

JavaScript

The question is how to log correctly in node, that is, I need information about each request, each accepted and given parameter to be displayed in the logs. Are there plugins for this and will it not be an extra load if there are a lot of logs?

Answer 1

As an option:

var log = fs.createWriteStream( __dirname + '/logs/express.log', {flags: 'a'} );
log.write( 'info' );

Answer 2

I use Sentry (albeit for exception handling, but you can also keep logs if you keep within the limit). Up to 5000 events per day - free of charge. For me, the pluses were - no need to create structures for storage, the possibility of a free account, you can keep logs on the client.
