log-timestamp

log-timestamp

Prepend timestamps to functions like console.log, console.warn, etc

Example

console.log('Before log-timestamp');
require('log-timestamp');
console.log('After log-timestamp');

yields

Before log-timestamp
[2012-08-23T20:08:32.000Z] After log-timestamp

You can specify a custom format as well

require('log-timestamp')('date="%s" message="%s"');
console.log('hello %s', 'world');

yields

date="2012-08-23T20:08:37.000Z" message="hello world"

Get fancy and pass in a function to call instead of new Date().toISOString()

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

yields

[1345752562432] hello world
