---title: Initializing Atom State on Renderdescription: How to initialize atom state on initial rendernav: 3.12---
There are times when you need to create an reusable component which uses atoms.
These atoms' initial state are determined by the props passed to the component.
Below is a basic example of illustrating how you can use `Provider` and its prop, `initialValues`, to initialize state.
### Basic Example
> CodeSandbox link: [codesandbox](https://codesandbox.io/s/strange-tdd-gb1eo0?file=/src/App.js).Consider a basic example where you have a reusable `TextDisplay` component that allows you to display and update plain text.
This component has two child components, `PrettyText` and `UpdateTextInput`.
- `PrettyText` displays the text in blue.- `UpdateTextInput` is an input field which updates the text value.As opposed to passing `text` as a prop in the two child components, you decided that the `text` state should be shared between components as an atom.
To make `TextDisplay` component reusable, we take in a prop `initialTextValue`, which determines the initial state of the `text` atom.
To tie `initialTextValue` to `textAtom`, we wrap the child components in a component where we create a new store and pass it to a `Provider` component.
```jsxconst textAtom = atom('')
const PrettyText = () => { const [text] = useAtom(textAtom) return ( <> <text style={{ color: 'blue', }}> {text} </text> </> )}
const UpdateTextInput = () => { const [text, setText] = useAtom(textAtom) const handleInputChange = (e) => { setText(e.target.value) } return ( <> <input onChange={handleInputChange} value={text} /> </> )}
export const TextDisplay = ({ initialTextValue }) => { const storeRef = useRef() if (!storeRef.current) { // initialising on state with prop on render here storeRef.current = createStore() storeRef.current.set(textAtom, initialTextValue) } return ( <Provider store={storeRef.current}> <PrettyText /> <br /> <UpdateTextInput /> </Provider> )}```
Now, we can easily resue `TextDisplay` component with different initial text values despite them referencing the "same" atom.
```jsxexport default function App() { return ( <div className="App"> <TextDisplay initialTextValue="initial text value 1" /> <TextDisplay initialTextValue="initial text value 2" /> </div> )}```
This behavior is due to our child components looking for the lowest commmon `Provider` ancestor to derive its value.
For more information on `Provider` behavior, please read the docs [here](https://jotai.org/docs/api/core#provider).
