Session Secrets

If you see this warning message when running a local jsbin command, you’ll want to set up a session secret.

Warning: Generating a session key

It means that you have not configured a session secret in your config.local.json or ENV. If you want your sessions to persist between reboots you’ll need to use the same one. JS Bin will generate a random 34 char key for you, you can choose to use this or one of your own.

You can either set an enviroment variable when you start jsbin (and this could be added to your local profile:

JSBIN_SESSION_SECRET=my_secret jsbin

Or you can add this directly to a your config.local.json like so:

  {
    "session": {
      "secret": "bfksfysa7e32kdhayu292sz"
    }
  }
