|
|
description: The useState composable creates a reactive and SSR-friendly shared state.
|

|
|
|
|
# `useState`
|
|
|
|
```ts
|
|
useState<T>(init?: () => T | Ref<T>): Ref<T>
|
|
useState<T>(key: string, init?: () => T | Ref<T>): Ref<T>
|
|
```
|
|
|
|
* **key**: A unique key ensuring that data fetching is properly de-duplicated across requests. If you do not provide a key, then a key that is unique to the file and line number of the instance of `useState` will be generated for you.
|
|
* **init**: A function that provides initial value for the state when not initiated. This function can also return a `Ref`.
|
|
* **T**: (typescript only) Specify the type of state
|
|

|
|
Because the data inside `useState` will be serialized to JSON, it is important that it does not contain anything that cannot be serialized, such as classes, functions or symbols.
