treechop: Manipulate and Traverse Tree Data in TypeScript

Overview

treechop provides functions for working with nested tree data and flat arrays of nodes linked by parent references. It covers common tasks such as traversal, searching, filtering, mapping, sorting, and conversion between representations.

It is suited to TypeScript and JavaScript projects that handle hierarchical data and want reusable operations rather than implementing each traversal themselves. Options allow callers to configure node keys and traversal order, while callbacks can receive metadata such as depth and parent nodes.

Key Features

• Traverse nodes using pre-order, post-order, or breadth-first strategies.
• Find, count, or test for nodes matching a predicate.
• Filter into a flat list or a tree, and search while retaining relevant branches.
• Map nodes into flat results or a transformed tree.
• Delete matching nodes while returning a tree result.
• Convert between nested trees and flat arrays with parent references.
• Sort nodes at each tree level by a selected key.
• Configure keys such as children, ID, and parent fields through options.

Use Cases

• TypeScript application developers can process nested menus, categories, or organizational structures without writing repeated traversal logic.
• Data-interface developers can filter a hierarchy for a search result while preserving its tree structure.
• Developers working with APIs that return parent-linked flat records can convert them into nested trees for presentation or processing.
• Teams transforming hierarchical records can map nodes while retaining structure, or flatten trees for downstream operations.

Getting Started

Install from npm:

npm install treechop

See the repository README for function signatures and examples.
