use_effect

Perform side effects in function components.

Parameters:

• setup (Callable[[], Any | Awaitable[Any]]) –

  A function that performs the side effect. It may optionally return a cleanup function.

• dependencies (Sequence[Any] | None, default: None ) –

  If present, the effect is only re-run when one of the dependencies has changed. If absent, the effect is only run on initial render.

• cleanup (Callable[[], Any | Awaitable[Any]] | None, default: None ) –

  An optional function that cleans up after the effect. It is run before the effect is re-run, and when the component unmounts.
