Widget State

Every instance of a widget has its own state. You can think of a widget’s state as its data representation. A widget with the same state should always render the same output. If you want to change how a widget looks in response to a user interaction, you should update its state!

Here’s an example of a widget that increments a count for every click:

Increment count with synced state
const { widget } = figma
const { Text, useSyncedState } = widget

function SimpleCounter() {
const [count, setCount] = useSyncedState("count", 0)
return (
onClick={() => {
setCount(count + 1)


We interchangeably refer to a widget's state as synced state because all of a widget's state is currently synced across all clients. In the future, we intend to support things like local state but for now all state is synced state.

We use the useSyncedState hook above to declare a data value on the widget that defaults to 0. Under-the-hood, you can think of this widget's state as a JSON object that looks like this:


If you have multiple useSyncedState calls, make sure you give them unique keys!

// initially
"count": 0

// click once
"count": 1

// click again
"count": 2

Each time this object gets updated, the associated widget is re-rendered to reflect the changes. Any JSON serializable value is a valid state value.
