What is @react-stately/collections?
@react-stately/collections is a library that provides utilities for managing collections of data in React applications. It offers a set of hooks and components to handle common collection operations such as iteration, filtering, and sorting in a declarative way.
What are @react-stately/collections's main functionalities?
Iterating over collections
This feature allows you to iterate over a collection of items and render them in a list. The `useCollection` hook is used to manage the collection state.
import { useCollection } from '@react-stately/collections';
const items = [
{ id: 1, name: 'Item 1' },
{ id: 2, name: 'Item 2' },
{ id: 3, name: 'Item 3' }
];
function MyComponent() {
const collection = useCollection({ items });
return (
<ul>
{collection.map(item => (
<li key={item.id}>{item.name}</li>
))}
</ul>
);
}
Filtering collections
This feature allows you to filter a collection of items based on a condition. The `filter` method is used to create a new array with items that match the condition.
import { useCollection } from '@react-stately/collections';
const items = [
{ id: 1, name: 'Item 1' },
{ id: 2, name: 'Item 2' },
{ id: 3, name: 'Item 3' }
];
function MyComponent() {
const collection = useCollection({ items });
const filteredItems = collection.filter(item => item.name.includes('1'));
return (
<ul>
{filteredItems.map(item => (
<li key={item.id}>{item.name}</li>
))}
</ul>
);
}
Sorting collections
This feature allows you to sort a collection of items based on a comparison function. The `sort` method is used to order the items in the collection.
import { useCollection } from '@react-stately/collections';
const items = [
{ id: 3, name: 'Item 3' },
{ id: 1, name: 'Item 1' },
{ id: 2, name: 'Item 2' }
];
function MyComponent() {
const collection = useCollection({ items });
const sortedItems = collection.sort((a, b) => a.name.localeCompare(b.name));
return (
<ul>
{sortedItems.map(item => (
<li key={item.id}>{item.name}</li>
))}
</ul>
);
}
Other packages similar to @react-stately/collections
react-table
react-table is a lightweight, fast, and extendable data grid built for React. It provides hooks for managing table state, including sorting, filtering, and pagination. Compared to @react-stately/collections, react-table is more focused on tabular data and provides more advanced features for table management.
react-virtualized
react-virtualized is a library for efficiently rendering large lists and tabular data in React. It provides components for virtualizing rows and columns, which can significantly improve performance for large datasets. While @react-stately/collections focuses on collection management, react-virtualized is specialized in optimizing rendering performance.
react-window
react-window is a lightweight library for rendering large lists and tabular data in React. It is similar to react-virtualized but with a smaller API surface and better performance. Like react-virtualized, it focuses on rendering performance, whereas @react-stately/collections provides utilities for managing collections.
