npm install -g facebook-refresh-token

{
  "server": {
    "protocol": "http",
    "host": "dummy.com",
    "port": 3000
  },
  "app": {
    "key": "",
    "secret": "",
    "scope": []
  },
  "browser": {
    "cookie": ""
  }
}

1. Create OAuth application on developers.facebook.com (in case you don't have one already)
2. Set the app's Site URL to http://dummy.com:3000 (or whatever else you want)
3. Add 127.0.0.1 dummy.com to your hosts file

1. Make sure you are logged in with your primary Facebook account that you are using regularly (this module relies on your browser cookie)
2. Create config.json file and copy/paste the above configuration data structure in it
3. Configure the server

• protocol, host and port should match your app's Site URL
• key App ID
• secret App Secret
• scope specify any scopes required by your app (optional)

1. Start the server facebook-refresh-token --config config.json --connect
2. Navigate to http://dummy.com:3000 in your browser
3. Open up the Developer Tools and select the Network tab, make sure Preserve log is checked
4. Navigate to http://dummy.com:3000/connect/facebook and authenticate as usual
5. Take a look at the authorization request in the Network tab and copy the request's cookie header value to the above configuration

1. Add 127.0.0.1 dummy.com to your hosts file
2. Deploy the config.json file to your server

1. Every time you want to update your access token execute:

facebook-refresh-token --config config.json --refresh

The refreshed access token is logged out to the console. This makes it easy to pipe this script's output to another one.

For example on Linux servers you may want to configure the cron daemon to refresh your access token at 12:00AM on the first day of every 3 months:

0 0 1 */3 * facebook-refresh-token --config config.json --refresh > access_token

Keep in mind that if you ever log out manually or due to prolonged inactivity of your Facebook account your cookie will be lost.

1. In this case execute the steps outlined in the Connect section on your workstation.
2. Update your server's config.json file with your new cookie value.
