 This **experimental** library provides Stackdriver Error Reporting support for client-side web JavaScript applications. [Stackdriver Error Reporting](https://cloud.google.com/error-reporting/) is a feature of Google Cloud Platform that allows in-depth monitoring and viewing of errors reported by applications running in almost any environment. For server-side Node.js error reporting, use [cloud-errors-nodejs](https://github.com/GoogleCloudPlatform/cloud-errors-nodejs) instead.
