Badger

a node logger that doesn't suck

Badger is a simple logger, providing the two things that are essential for maintainable logging:

• automatic printing of file/line number where the log message happened
• easy local/global granularity controls

Installation

npm install badger

Usage

main.js

var badger = require("badger")(__filename);

badger.error("An error");
badger.warning("A warning");
badger.debug("A debug statement");

Output

[error] main.js:3: An error
[warning] main.js:4: A warning

The debug message is not shown because the highest level log message shown by default is a warning. In order to show debug messages in the scope of a single file, you can do this:

badger.setLevel("debug");

# debug messages will now be shown

Debug messages can also be set to be shown globally:

badger.setGlobalLevel("debug");

Where's badger.log?

badger is intentionally does not include a generic log command, because I believe that a generic log command encourages sloppy, unmaintainble logging. All logs can be categorized as either warnings, errors, or debug messages.
