What is @react-stately/select?

@react-stately/select is a library that provides state management for select components in React applications. It is part of the React Spectrum collection of libraries, which are designed to work together to build accessible, high-quality user interfaces.

What are @react-stately/select's main functionalities?

Basic Select State Management

This feature allows you to manage the state of a select component, including the list of items and the currently selected item.

import { useSelectState } from '@react-stately/select';

const state = useSelectState({
  items: [
    { key: 'red', name: 'Red' },
    { key: 'green', name: 'Green' },
    { key: 'blue', name: 'Blue' }
  ],
  selectedKey: 'red'
});

console.log(state.selectedKey); // 'red'

Handling Selection Changes

This feature allows you to handle changes in the selection state, providing a callback function that is called whenever the selected item changes.

import { useSelectState } from '@react-stately/select';

const state = useSelectState({
  items: [
    { key: 'red', name: 'Red' },
    { key: 'green', name: 'Green' },
    { key: 'blue', name: 'Blue' }
  ],
  selectedKey: 'red',
  onSelectionChange: (key) => console.log('Selected:', key)
});

state.setSelectedKey('green'); // Logs: 'Selected: green'

Multiple Selection

This feature allows you to manage multiple selections within a select component, including handling changes to the set of selected items.

import { useSelectState } from '@react-stately/select';

const state = useSelectState({
  items: [
    { key: 'red', name: 'Red' },
    { key: 'green', name: 'Green' },
    { key: 'blue', name: 'Blue' }
  ],
  selectedKeys: new Set(['red']),
  selectionMode: 'multiple',
  onSelectionChange: (keys) => console.log('Selected keys:', keys)
});

state.setSelectedKeys(new Set(['green', 'blue'])); // Logs: 'Selected keys: Set { 'green', 'blue' }'
