And weight is an integer.Īll normal cells have a weight of 1, and the weighted cells have a weight of 5. iswall is a Boolean that's only true for walls. istarget is similar, but for the target node. isstarting is a Boolean that's only true for the starting cell. X and y represent the coordinates of the cell. Here, you'll write a function that returns a grid which is a two dimensional array of objects representing the cells.Įach object will have these properties: x, y, isstarting, istarget, iswall, and weight. Now in the utils folder, create a startingGrid.js file. įor the representation of the grid and the cells, I will be building a two dimensional array of objects containing all the properties we need to represent a certain cell. After adding these links you should notice the font changing. To do this, just add the Bootstrap CDN to the head tag in your HTML file. Now we need to add bootstrap to our project for the buttons and icons we're going to add, since we need to focus on the JavaScript part.

Here's a screenshot of what your project should look like: Project folder structure How to Add Bootstrap Now inside the src folder, create a components folder, a contexts folder, and a utils folder – and you're done. Then using the terminal, navigate to this directory and run these commands: $ npm create my-app Create a folder in a well-known directory on your machine.

In this tutorial we will be using Visual Studio Code (but you can use any editor you want), a command line prompt, some basic React, ES6 JavaScript, and HTML and CSS.įor this tutorial I will be using Vite, which is a tool that helps you start projects way faster than npm create-react-app.įirst, install Vite if you haven't done that yet. Here's the final version of what we're going to build and here's the source code on my GitHub account. You should also have a basic understanding of React.

In case you need to review, I will leave a link for a YouTube video explaining the two algorithms. To go through this tutorial, you should have a basic understanding of BFS and DFS. This will help us identify features like streets with high traffic that you don't want to take. It will support Breadth-First Search (BFS), Depth-First Search (DFS), adding walls, and weighting nodes for weighted graph algorithms like Dijkstra's. In this tutorial we will be building a path finding algorithm visualizer with React. These algorithms are widely used in map applications like Google Maps, for example. Path-finding algorithms are algorithms used to find optimal path between two locations.
