Query the Grafana k6 Extension Registry database.

The Grafana k6 Extension Registry Service enables read-only access to the Grafana k6 Extension Registry database.

The Grafana k6 Extension Registry database contains up-to-date information about registered extensions. The basic data of the extensions (e.g. go module path, JavaScript import path, description) are registered manually, the other data (e.g. available versions, number of stars) are retrieved automatically via the repository manager API (GitHub, GitLab, etc.).

Detailed information about response schemas can be found in the schema documentation. Schemas are defined in registry.schema.json

The source code of extensions is automatically statically analyzed. The result of the analysis is the compliance level of the best practices of Grafana k6 extensions (0-100%). Based on the compliance level, a compliance grade is also calculated (A-F). Based on the compliance grade, an SVG compliance badge is created for each extension. Example badge:

xk6-sql

The k6 Extension Catalog is an alternative representation of the k6 Extension Registry. Most queries have an alternative counterpart that returns a catalog instead of a registry.

You can try the k6 Extension Registry Service!

Information about modifying the registry (register new extensions, modify or delete existing registrations) can be found in the grafana/k6-extension-registry GitHub repository.
