Sentry Raven Middleware for Redux

raven-for-redux is a Redux middleware designed to integrate Redux state and actions with Sentry's error tracking platform through the legacy raven-js client. It intercepts dispatched actions, logging their types as breadcrumbs and attaching the last action and current Redux state as additional context to all errors, not just reducer exceptions. As of version 1.4.0, it requires raven-js version 3.9.0 or higher, with a known bug triggered by raven-js 3.14.0. The library differentiates itself by allowing the Sentry Raven client to be injected, providing flexible configuration, and offering options to filter action breadcrumbs and define user context mappings from the Redux state. Its release cadence has been infrequent, and its primary dependency, raven-js, is officially deprecated in favor of `@sentry/browser`, making this package suitable only for projects using older Sentry integrations.
