## Installation
Install `react-paginate` with [npm](https://www.npmjs.com/):
```
npm install react-paginate --save
```
## Usage
```javascript
import React, { useEffect, useState } from 'react';
import ReactDOM from 'react-dom';
import ReactPaginate from 'react-paginate';
// Example items, to simulate fetching from another resources.
const items = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14];
function Items({ currentItems }) {
return (
<>
{currentItems &&
currentItems.map((item) => (
<div>
<h3>Item #{item}</h3>
</div>
))}
</>
);
}
function PaginatedItems({ itemsPerPage }) {
// We start with an empty list of items.
const [currentItems, setCurrentItems] = useState(null);
const [pageCount, setPageCount] = useState(0);
// Here we use item offsets; we could also use page offsets
// following the API or data you're working with.
const [itemOffset, setItemOffset] = useState(0);
useEffect(() => {
// Fetch items from another resources.
const endOffset = itemOffset + itemsPerPage;
console.log(`Loading items from ${itemOffset} to ${endOffset}`);
setCurrentItems(items.slice(itemOffset, endOffset));
setPageCount(Math.ceil(items.length / itemsPerPage));
}, [itemOffset, itemsPerPage]);
// Invoke when user click to request another page.
const handlePageClick = (event) => {
const newOffset = (event.selected * itemsPerPage) % items.length;
console.log(
`User requested page number ${event.selected}, which is offset ${newOffset}`
);
setItemOffset(newOffset);
};
return (
<>
<Items currentItems={currentItems} />
<ReactPaginate
breakLabel="..."
nextLabel="next >"
onPageChange={handlePageClick}
pageRangeDisplayed={5}
pageCount={pageCount}
previousLabel="< previous"
renderOnZeroPageCount={null}
/>
</>
);
}
// Add a <div id="container"> to your HTML to see the componend rendered.
ReactDOM.render(
<PaginatedItems itemsPerPage={4} />,
document.getElementById('container')
);
```

You can also read the code of [demo/js/demo.js](https://github.com/AdeleD/react-paginate/blob/master/demo/js/demo.js) to quickly understand how to make `react-paginate` work with a list of objects.
Finally there is this **[CodePen demo](https://codepen.io/monsieurv/pen/yLoMxYQ)**, with features fetching sample code (using GitHub API) and two synchronized pagination widgets.

| `pageCount` | `Number` | **Required.** The total number of pages. |
| `pageRangeDisplayed` | `Number` | The range of pages displayed. |
| `marginPagesDisplayed` | `Number` | The number of pages to display for margins. |
| `previousLabel` | `Node` | Label for the `previous` button. |
| `nextLabel` | `Node` | Label for the `next` button. |
| `breakLabel` | `Node` | Label for ellipsis. |
| `breakClassName` | `String` | The classname on tag `li` of the ellipsis element. |
| `breakLinkClassName` | `String` | The classname on tag `a` of the ellipsis element. |
| `onPageChange` | `Function` | The method to call when a page is changed. Exposes the current page object as an argument. |
| `onClick` | `Function` | A callback for any click on the component. Exposes information on the part clicked (for eg. `isNext` for next control), the next expected page `nextSelectedPage` & others. Can return `false` to prevent any page change or a number to override the page to jump to. |
| `onPageActive` | `Function` | The method to call when an active page is clicked. Exposes the active page object as an argument. |
| `initialPage` | `Number` | The initial page selected, in [uncontrolled mode](https://reactjs.org/docs/uncontrolled-components.html). Do not use with `forcePage` at the same time. |
| `forcePage` | `Number` | To override selected page with parent prop. Use this if you want to [control](https://reactjs.org/docs/forms.html#controlled-components) the page from your app state. |
| `disableInitialCallback` | `boolean` | Disable `onPageChange` callback with initial page. Default: `false` |
| `containerClassName` | `String` | The classname of the pagination container. |
| `className` | `String` | Same as `containerClassName`. For use with [styled-components](https://styled-components.com/) & other CSS-in-JS. |
| `pageClassName` | `String` | The classname on tag `li` of each page element. |
| `pageLinkClassName` | `String` | The classname on tag `a` of each page element. |
