title: What happens to temp files in Heroku (Node application)
body: <p>I have a free Heroku account and my Node app uses Amazon S3 to store files. I ham using s3fs module along with multiparty-middleware which first temporarily stores the files and then uploads it to S3.</p>
  
  <p>After the file is uploaded and unlinked in fs, the file still remains in my local temp folder during local development. I have deployed the same code on my Heroku app and I am worried if there is any way to check the temp folder or delete it daily because the app has slug size limit of 500mb and the uploaded files can be even more than 100s of Mbs.</p>
