During March 2025, Juani Cabanas developed comprehensive documentation for the grafana/plugin-tools repository, focusing on enabling external data source plugin support for externally shared dashboards. Juani outlined the necessary backend development steps, such as extending DataSourceWithBackend and implementing the query method in TypeScript, while also detailing required updates to plugin.json in JSON format. The work clarified that frontend data sources are incompatible with externally shared dashboards, helping prevent future misconfigurations. By addressing both technical implementation and integration risks, Juani’s contribution provided clear, actionable guidance for plugin developers and established a solid foundation for cross-dashboard data sharing in Grafana.
