rollbar.js - Ignore error types using checkIgnore

example.js

// List of error class names to ignore
var ROLLBAR_IGNORED_CLASS_NAMES = ['ReferenceError'];

var _rollbarConfig = {
  accessToken: '<your access token>',
  captureUncaught: true,
  captureUnhandledRejections: true,
  payload: {
      environment: '<your env name>'
  },
  checkIgnore: function(isUncaught, args, payload) {
    // payload is a json object with the data that is about to be sent to the Rollbar API. 
    // it has the structure as can be seen in the Rollbar UI for the occurrence.
    // so, if you see occurrences in the Rollbar UI that you want to ignore, you can use the "raw json" view to see the
    // structure, and then code against that in your checkIgnore function (like this example) to ignore them in the future.
    
    // Here we have an example checkIgnore that will ignore when the class name is in our list of ignored class names
    // (see ROLLBAR_IGNORED_CLASS_NAMES defined above).
    // Return true to ignore.
    var trace = payload.body.trace;
    if (trace && trace.exception) {
      if (ROLLBAR_IGNORED_CLASS_NAMES.indexOf(trace.exception.class) !== -1) {
        // matches ignore list - return true to ignore
        return true;
      }
    }
  }
};

// If you are using the standard rollbar.js snippet, the minified snippet code would go here.
// If you are using rollbar.js some other way (i.e. installed as a package), then you can configure as follows:
Rollbar.configure(_rollbarConfig);
