Data Theft Repackaged: A Case Study in Malicious Wrapper Packages on npm
The Socket Research Team breaks down a malicious wrapper package that uses obfuscation to harvest credentials and exfiltrate sensitive data.
@react-stately/tree
Advanced tools
@react-stately/tree is a library for managing state in tree-like structures in React applications. It provides hooks and utilities to handle tree data, selection, expansion, and other common tree operations.
Tree Data Management
This feature allows you to manage tree data structures. The `useTreeState` hook initializes the tree state with the given tree data and selection mode.
import { useTreeState } from '@react-stately/tree';
const tree = {
name: 'root',
children: [
{ name: 'child 1' },
{ name: 'child 2', children: [{ name: 'grandchild 1' }] }
]
};
const state = useTreeState({
tree,
selectionMode: 'multiple'
});
console.log(state.collection);
Selection Management
This feature allows you to manage selection within the tree. The `selectionManager` provides methods to toggle selection and access selected keys.
import { useTreeState } from '@react-stately/tree';
const tree = {
name: 'root',
children: [
{ name: 'child 1' },
{ name: 'child 2', children: [{ name: 'grandchild 1' }] }
]
};
const state = useTreeState({
tree,
selectionMode: 'multiple'
});
state.selectionManager.toggleSelection('child 1');
console.log(state.selectionManager.selectedKeys);
Expansion Management
This feature allows you to manage the expansion state of tree nodes. The `expansionManager` provides methods to toggle expansion and access expanded keys.
import { useTreeState } from '@react-stately/tree';
const tree = {
name: 'root',
children: [
{ name: 'child 1' },
{ name: 'child 2', children: [{ name: 'grandchild 1' }] }
]
};
const state = useTreeState({
tree,
selectionMode: 'multiple'
});
state.expansionManager.toggleExpansion('child 2');
console.log(state.expansionManager.expandedKeys);
react-treebeard is a React component for rendering tree structures. It provides a simple and customizable way to display hierarchical data. Unlike @react-stately/tree, it focuses more on rendering and less on state management.
react-sortable-tree is a React component for displaying and sorting tree structures. It offers drag-and-drop functionality for rearranging nodes. Compared to @react-stately/tree, it provides more advanced interaction features but less focus on state management.
react-dnd-treeview is a React component for creating draggable and droppable tree views. It leverages the react-dnd library for drag-and-drop interactions. While it offers robust drag-and-drop capabilities, it does not provide the same level of state management as @react-stately/tree.
This package is part of react-spectrum. See the repo for more details.
