useBackendStrict variable

Hook to get analytical backend instance provided to BackendProvider.

Signature:

useBackendStrict: (backend?: IAnalyticalBackend | undefined, context?: string) => IAnalyticalBackend

Remarks

You can set a backend override that will be returned if defined. This makes the usage more ergonomic (see the following example).

Note: If you do not provide an IAnalyticalBackend instance to BackendProvider or as a parameter for this hook, an invariant error is raised.

Example

// instead of
const fromContext = useBackendStrict();
const effectiveBackend = fromArguments ?? fromContext.
// you can write
const backend = useBackendStrict(fromArguments);
