title: How to use Winston in several modules?
body: <p>I have several modules - let's say server.js, module1.js,...,moduleN.js.</p>
  
  <p>I would like define the log file in my server.js:</p>
  
  <pre><code>winston.add(winston.transports.File, { filename: 'mylogfile.log' });
  </code></pre>
  
  <p>and then use it in all my modules.</p>
  
  <p>What is the best way to do that? I could <code>exports.winston=winston;</code> in each module and then set it in the server.js, but is there any better solution?</p>
  
  <p>Thank you in advance!</p>
