Report errors and unhandled exceptions to Rollbar.com service in your Flow/Neos project.

It is especially useful on Production environment, where you don't want to have any exceptions or errors unnoticed.


  • Error and exception logging:
    • on server-side (PHP, both web requests and CLI requests)
    • on front-end (JS) for public site and Neos admin areas (content module and all other modules, like Media, Workspaces etc)
  • Enabled by default for Production only, can be enabled for Development too.
  • Sending environment and currently authenticated account identifier, if present.
  • Tested with Flow 3.3, Neos 2.3 and PHP 7.0 (should work on PHP 5.6 up).


Install it with composer:

composer require m12/flow-rollbar


Configure your settings in Configuration/Settings.yaml. You can disable Rollbar error reporting for front-end JavaScript or enable/disable it for prod/dev environement.

The following are the defaults:

    # Enables Rollbar reporting for Production context
    enableForProduction: true
    # Enables Rollbar reporting for Development context
    enableForDevelopment: false

    # Enables Rollbar on the front-end, in the browser
    # @see rollbarJsSettings below
    enableForFrontend: true

    # Server-side configuration
    # You can add here any setting option described in rollbar-php
    # docs: https://github.com/rollbar/rollbar-php
    # Note: the `root`, `environment` and `person_fn` options are automatically filled.
      access_token: your POST_SERVER_ITEM access token here
      batch_size: 10

    # Front-end side configuration
    # You can add here any option available in
    # https://rollbar.com/docs/notifier/rollbar.js/ .
    # Note: the `payload.environment` and `payload.person` options are automatically filled.
      accessToken: your POST_CLIENT_ITEM access token here
      captureUncaught: true
      captureUnhandledRejections: true
      payload: {}

    # Path to Rollbar html/js template
    templatePath: 'resource://M12.Rollbar/Private/Templates/Rollbar.html'

    # Assuming FLOW_CONTEXT contains sub-context, should it be sent in the `environment` key?
    # When set to false *and* sub-context *is* present, whole FLOW_CONTEXT will be sent as a separate metadata.
    includeSubContextInEnvironment: false

Server-side error reporting

Configure it in rollbarSettings. You'll need at least provide the API access token app (the post_server_item from your Rollbar app) to rollbarSettings.access_token. You can add here any setting option described in rollbar-php doc: https://github.com/rollbar/rollbar-php.

Frontend (javascript) error reporting

Configure it in rollbarJsSettings. At least accessToken value needs to be provided (the post_client_item from your Rollbar app). You can add here any setting option described in rollbar JS doc: https://rollbar.com/docs/notifier/rollbar.js/.


Frontend integration in Neos works out-of-the box, both for the public site and all Neos CMS admin areas (content module and other sub-modules, i.e. Media, History etc).

To enable Rollbar only on Neos CMS admin panel, you could add the following line to your .ts code:

prototype(TYPO3.Neos:Page) {
	head {
		rollbar = TYPO3.TypoScript:Template {
			@if.onlyRenderWhenNotInLiveWorkspace = ${node.context.workspace.name != 'live'}

Note: the implementation of front-end side of things can be a bit tricky. Views are configured to override Neos' Default.html layout to render Rollbar config and JS snippet on all Neos back-end (sub)modules. Beware of that if you have overridden the default Neos layout it in your setup. Apart of that, we have a bit of .ts code (automatically included) to add Rollbar snippet to the page HEAD section, both when in Neos content module or in live site.


Front-end integration requires adding a Rollbar snippet to your template (or perhaps layout, so it's shared amongst all different views).

Add Rollbar snippet to your front-end layout code using <rollbar:renderRollbar /> tag. Remember to add rollbar namespace at the very top of the file.

Rollbar recommends adding it at the very top of the HEAD section, at least before any other .js code. Your code could look something like that:

{namespace rollbar=M12\Rollbar\ViewHelpers}
<!DOCTYPE html>
	<meta charset="utf-8">
	<rollbar:renderRollbar />
