useBackend variable

Hook to get analytical backend instance provided to BackendProvider.

Signature:

useBackend: (backend?: IAnalyticalBackend | undefined) => IAnalyticalBackend | undefined

Remarks

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

Note: For a better TypeScript experience without the hassle of undefined values, you can use the useBackendStrict hook.

Example

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