console.log('before log-prefix');
require('log-prefix')('==> %s <==');
console.log('after log-prefix');

You can specify a function instead of a string. The function must return a string to be used (good for dynamic values).

require('log-prefix')(function() { return '[' + Date.now() + '] %s' });
console.log('hello %s', 'world');

yields

[1371582989993] hello world
npm install log-prefix
npm test
