Athro

Algorithms and data structures for TypeScript and JavaScript, with interactive documentation for every algorithm.

Documentation · Getting Started · npm · Issues

Overview

Athro is a typed library of classic algorithms and data structures. It ships dual CommonJS and ESM builds with TypeScript declarations, and works in Node.js, Bun, Deno, and modern browsers.

Each algorithm in the documentation includes an interactive step-by-step visualization.

Install

npm install athro

pnpm add athro

yarn add athro

Quick example

import { heapSort, Graph, graphBfs, dijkstra, HashMap, BinarySearchTree, bubbleSort } from 'athro';

// Sorting
bubbleSort([8, 3, 6, 2]);
heapSort([8, 3, 6, 1]);

// Hash map
const map = new HashMap<string, number>();
map.set('key', 42);
map.get('key'); // 42

// Graph
const graph = new Graph<string>(true);
graph.addEdge('A', 'B', 4);
graph.addEdge('B', 'C', 2);

graphBfs(graph, 'A');
dijkstra(graph, 'A', 'C');

// Binary search tree
const bst = new BinarySearchTree<number>();
bst.insert(10);
bst.isPresent(10); // true

Usage

Import named exports from the package entry point:

import { mergeSort, Stack, Queue } from 'athro';

const stack = new Stack<number>();
stack.push(1);
stack.push(2);
stack.pop();

mergeSort([4, 2, 7, 1, 3]);
