easystar.js is a small (~7kb) asynchronous A* pathfinding library for JavaScript, usable in HTML5 games and interactive projects. It works on tile-based grids with support for diagonals, tile costs, directional conditions, and incremental calculation to keep performance smooth.

Use cases

• find paths on a tilemap grid for an HTML5 game
• implement NPC movement with A* pathfinding in JavaScript
• compute paths asynchronously to avoid blocking the browser frame loop
• add weighted tiles and avoid-points to pathfinding in a grid game
• use pathfinding with Phaser or other JS game frameworks
• enable diagonal movement and corner cutting on a grid

When to choose

• you need lightweight A* pathfinding on a 2D tile grid in JavaScript
• you want asynchronous/incremental path calculation for large grids
• you use Phaser, plain JS, or Node.js and want a simple pathfinding API

When to avoid

• you need continuous-space or navigation-mesh pathfinding rather than tile grids
• you need synchronous, guaranteed-instant results without calling calculate()
• your project is not JavaScript/TypeScript based
