|---|---|
| AngularComponent | Used to enable rendering of Angular components within a React component without losing proper typings. |
| AngularLoader | Used to load an Angular component from the context of a React component. Please see the AngularComponent for a proper example. |
| AzureSettings | |
| BackendSrv | Used to communicate via http(s) to a remote backend such as the Grafana backend, a datasource etc. The BackendSrv is using the Fetch API under the hood to handle all the communication.The request function can be used to perform a remote call by specifying a BackendSrvRequest. To make the BackendSrv a bit easier to use we have added a couple of shorthand functions that will use default values executing the request. |
| DashboardInfo | Describes the basic dashboard information that can be passed as the meta analytics payload. |
| DashboardViewEventPayload | Describes the payload of a dashboard view event. |
| DataRequestEventPayload | Describes the payload of a data request event. |
| DataRequestInfo | Describes the data request information passed as the meta analytics payload. |
| DataSourceSrv | This is the entry point for communicating with a datasource that is added as a plugin (both external and internal). Via this service you will get access to the DataSourceApi that have a rich API for communicating with the datasource. |
| EchoBackend | Describes echo backends that can be registered to receive of events. |
| EchoEvent | Describes an echo event. |
| EchoMeta | Describes the meta information that are sent together with each event. |
| EchoSrv | Used to send events to all the registered backends. This should be accessed via the getEchoSrv() function. Will, by default, flush events to the backends every 10s or when the flush function is triggered. |
| ExperimentViewEchoEventPayload | Describes the payload of an experimentview event. |
| FetchError | Error type for fetch function in BackendSrv |
| FetchErrorDataProps | Error type for fetch function in BackendSrv |
| FetchResponse | Response for fetch function in BackendSrv |
| GetDataSourceListFilters | |
| HealthCheckResult | Describes the payload returned when checking the health of a data source plugin. |
| InteractionEchoEventPayload | Describes the payload of a user interaction event. |
| LocationService | A wrapper to help work with browser location and history |
