Tutorial for my original Pathfinding Visualizer project.
A companion codebase to a YouTube tutorial series by Clement Mihailescu showing how to build a pathfinding visualizer in React. It implements Dijkstra's algorithm on a grid with wall-drawing and animation. Aimed squarely at CS students or bootcamp grads learning algorithms and React simultaneously.
The grid + node architecture is clean enough to follow without the video — Node.jsx is self-contained and the CSS animation approach for visited nodes is a reasonable teaching choice. Dijkstra implementation in a single file keeps the algorithm surface area readable. Good starting point for extending with A*, BFS, or DFS since the structure is obvious.
Only Dijkstra is implemented — the tutorial repo was never completed with additional algorithms despite that being the point. Last touched in 2023, still on Create React App which is effectively unmaintained; any new work here means migrating the toolchain first. No tests beyond the default CRA placeholder. The README is mostly auto-generated boilerplate with a YouTube plug — not much guidance on how the code actually works.
