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.
