Grafana Faro Web SDK

The Grafana Faro Web SDK can instrument frontend JavaScript applications to collect telemetry and forward it to the Grafana Alloy (with faro receiver integration enabled), to a Grafana Cloud instance or to a custom receiver. Grafana Alloy can then send this data to Loki or Tempo.

The repository consists of multiple packages that can be combined depending on your requirements, as well as a demo, which can be run by following the README.md file.

Releases

Faro releases follow the Semantic Versioning naming scheme: MAJOR.MINOR.PATCH.

• MAJOR: Major releases include large new features which will significantly change how Faro operates and possible backwards-compatibility breaking changes.

• MINOR: these releases include new features which generally do not break backwards-compatibility.

• PATCH: patch releases include bug and security fixes which do not break backwards-compatibility.

  NOTE: Our goal is to provide regular releases that are as stable as possible, and we take backwards-compatibility seriously. As with any software, always read the release notes and the upgrade guide whenever choosing a new version of Faro to install.

Supported Node versions

Faro supports all active LTS (Long Term Support) and current Node versions. When Node.js versions reach end-of-life, we remove them from our test matrix and add new versions as they are released. You can find a release schedule on nodejs.org
