npm Updates Search Experience with New Objective Sorting Options
npm has a revamped search experience with new, more transparent sorting options—Relevance, Downloads, Dependents, and Publish Date.
@react-aria/utils
Advanced tools
The @react-aria/utils package provides a collection of utility functions that help in managing accessibility concerns in React applications. These utilities assist in handling keyboard, focus, and selection behaviors, making it easier to build accessible UI components.
Focus Management
This feature allows you to focus an element without causing the browser to scroll to it, which can be useful in maintaining the user's scroll position while programmatically moving focus.
import { focusWithoutScrolling } from '@react-aria/utils';
function handleFocus(element) {
focusWithoutScrolling(element);
}
Keyboard Event Handling
This utility helps in filtering out non-DOM properties from props, ensuring that only valid HTML attributes are passed to the DOM element, thus preventing React warnings and improving HTML output.
import { filterDOMProps } from '@react-aria/utils';
function Button(props) {
return <button {...filterDOMProps(props)}>Click me</button>;
}
Merge Props
Merge props from different sources, typically used to combine default and user-provided props in a component. It ensures that event handlers and other attributes are correctly combined and overridden if necessary.
import { mergeProps } from '@react-aria/utils';
function mergeComponentProps(userProps, defaultProps) {
return mergeProps(defaultProps, userProps);
}
Downshift is a library that provides primitives to build simple, flexible, WAI-ARIA compliant enhanced input React components. Its focus on accessibility and functionality related to dropdowns and comboboxes makes it similar but more specialized compared to the broad utility focus of @react-aria/utils.
React-focus-lock provides a robust solution for trapping focus within a DOM node, which is crucial for building accessible modal dialogs. While it focuses specifically on focus management, @react-aria/utils offers this alongside other utilities, making it more versatile.
This package is part of react-spectrum. See the repo for more details.
