Welcome to Log Magic.

This project isn't usable yet. No promises. The Bellow is an idea.

The goal is to have a fast and easy to use logging subsystem that can be dynamically reconfigured to provide insight into production systems.

Getting Started

If you had a file named like, "lib/foo/bar.js", at the top of it, you would put the following:

var log = require('logmagic').local('mylib.foo.bar');

Then inside bar.js, you would just use the logger like any normal logger:

log.info("Hello!")
log.error("Accepts format strings too ${SOME_VAR}", {SOME_VAR: "myvalue"})

In any other part of your application, you can reconfigure the logging subsystem at runtime, making it easy to change log levels for specific modules dynamically.

var logmagic = require('logmagic');
logmagic.registerSink("mysink", function(level, message) { console.log(message); });

/* Send Info an higher in the root logger to stdout */
logmagic.route("__root__", logmagic.INFO, "stdout")

/* Reconfigure all children of mylib to log all debug messages to your custom sink */
logmagic.route("mylib.*", logmagic.DEBUG, "mysink")

Builtin sinks include:

  • Standard Error
