lazy_pathfinding

This Deno library implements several pathfinding and graph algorithms.

Where possible, this library does not need an entire graph to be provided to it ahead of time. Many functions allow nodes and edges to be provided by a successor function executed for each node encountered, meaning that graphs are lazily initialized which allows for procedural and infinite graphs to be used.

Algorithms

The algorithms are generic over their arguments.

Directed graphs

A*: find the shortest path in a weighted graph using an heuristic to guide the process.

Undirected graphs

connected components: find disjoint connected sets of vertices.

Documentation

See the generated docs at https://deno.land/x/lazy_pathfinding?doc.

Using this library

import { aStar } from "https://deno.land/x/lazy_pathfinding/directed/a_star.ts";

This project was ported from the Rust pathfinding library.
