rollbar.js - ignore errors that aren't from a given domain (using rollbar.js version 0.10.8)

gistfile1.js

_rollbarConfig = {
  "server.environment": "production",
  // any other existing config...
  checkIgnore: function(errMsg, file, line, col, err) {
    // this function is called for all uncaught errors
    // if it returns true, the error will be ignored
    // instead of being reported to Rollbar.
    
    if (file && !file.match(/^https?:\/\/www\.mycompany\.com/)) {
      // has a filename, but filename (url) is not on www.mycompany.com.
      // ignore.
      return true;
    }
    // don't ignore anything else
    return false;
  }
}
