js-bufflog

logger for all javascript and typescript Buffer services

Usage

import bufflog from "BuffLog";

bufflog.debug('hello critical', {"some":"stuff"});
bufflog.info('hello info');
bufflog.notice('hello notice with context', {"foo":"bar"});
bufflog.error('hello error');
bufflog.critical('hello critical');

Log verbosity levels

If you wish to see more logs, simply set the LOG_LEVEL to the desired level. Here a list with some use case:

Levels	Use case	Examples
DEBUG	Logs that are used for interactive investigation during development. These logs should primarily contain information useful for debugging and have no long-term value.
INFO	Informational messages
NOTICE	Logs that track the general flow of the application. This is the default level
WARNING	Logs that highlight an abnormal or unexpected event in the application flow, but do not otherwise cause the application execution to stop.
ERROR	Logs that highlight when the current flow of execution is stopped due to a failure. These should indicate a failure in the current activity, not an application-wide failure.
CRITICAL	Logs that describe an unrecoverable application or system crash, or a catastrophic failure that requires immediate attention.

Add traces to log

A great feature of Datadog is to correlate traces and logs to make troubleshooting easier.

To take advantage of this, you will need to:

• install the dd-trace package
• import it and init it with logInjection:true.
• BuffLog will append automatically the traces to the logs (only within a request)

// make sure to put those lines at the very beginning of your service
import tracer from "dd-trace";
tracer.init({
    //  will automatically append the traces to BuffLog
    logInjection: true

    // ... all other options...
});
