# use-debounce-state

creates a bottleneck to the definition of a state, limits concurrency.

### Module

```javascript
import { useDebounceState } from "@atomico/hooks/use-debounce-state";
```

### Syntax

this hook is similar to useState, but the purpose of this hook is to bottleneck the state at update time

```javascript
const [state, setState] = useDebounceState(
    delay:number, 
    initialState: any,
    mode?: "fps" | "timeout" | "idle"
);
```

**mode differences**

1. **fps**: 
   1. if delay is set to 1, the update is executed for each cycle of requestAnimationFrame(60fps),   
   2. if delay is defined as 2, the update is executed for every 2 cycle of requestAnimationFrame(30fps)
2. **timeout**: the delay will be the milliseconds for setTimeout
3. **idle** : the delay will be the milliseconds for requestIdleCallback

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://atomico.gitbook.io/doc/packages/atomico-hooks/use-debounce-state.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
