Quick Examples

Basic usage

// test/foo.js
import debug from 'debug-filename';

// DEBUG can be triggered by the following format:
// - DEBUG=app:test:foo
// - DEBUG=app:test:*
// - DEBUG=app:*
// - DEBUG=*
debug('logging data'); // "app:test:foo logging data"

Advanced usage

• Modify App name

  // test/foo.js
  import debug from 'debug-filename';
  
  // DEBUG_FILENAME_PREFIX=Application DEBUG=Application:test:foo
  debug('logging data'); // "Application:test:foo logging data"
  

• Stripped off the first layer of the catalog

  // test/foo.js
  import debug from 'debug-filename';
  
  // DEBUG_FILENAME_START=1 DEBUG=app:foo
  debug('logging data'); // "app:foo logging data"
  

• Specify the length of the namespace

  // test/a/b/c/d.js
  import debug from 'debug-filename';
  
  // DEBUG_FILENAME_LENGTH=2 DEBUG=app:test:a
  debug('logging data'); // "app:test:a logging data"
