Connect 4: A World of Workflows Implementation

In this blog post, we will explore an exciting implementation of the classic game Connect 4 using the World of Workflows platform. The workflow provided[1] demonstrates how to create a simple web-based Connect 4 game using HTTP endpoints and JavaScript.

You could look throught the following technical detail. Or create your own with the following ChatGPT Prompt: Write a connect 4 game in html and JS and CSS in a single html file

Workflow Overview

The Connect 4 workflow consists of two main activities:

  1. HTTP Endpoint: This activity listens for incoming HTTP requests at the `/connect4` path and accepts `GET` requests. It acts as the entry point for the game.

  2. HTTP Response: This activity sends an HTML response containing the game's user interface and logic. The response includes the game board, styles, and JavaScript code to handle user interactions and game logic.

Game Interface

The game interface is built using HTML and CSS. The game board is represented by a `div` element with an ID of `board`. Each cell in the board is a `div` element with a class of `cell`, and additional classes for the cell's state (`.red`, `.yellow`, or `.empty`). The board's appearance is defined using CSS styles[1].

Game Logic

The game logic is implemented using JavaScript. The code initializes an empty 6x7 board and provides functions to handle user moves, computer moves, and checking for a win condition. The game alternates between the human player (red) and the computer player (yellow) [1].

Key Functions

  • initializeBoard(): Initializes the board as a 6x7 array with all cells set to 'empty'.

  • drawBoard(): Renders the board on the web page, creating a column for each board column and a cell for each board cell.

  • humanMove(column): Handles the human player's move by updating the board and checking for a win condition.

  • computerMove(): Handles the computer player's move by finding the best move or making a random move if no winning move is found.

  • findBestMove(player): Searches for a winning move for the specified player by iterating through all possible moves.

  • makeMove(column, player): Updates the board with the specified player's move and checks for a win condition.

  • checkWin(): Checks if there is a winning combination on the board.

  • resetBoard(): Resets the board to its initial state and sets the current player to 'red'.


This World of Workflows implementation of Connect 4 demonstrates how to create a simple web-based game using HTTP endpoints, HTML, CSS, and JavaScript. The workflow provides a solid foundation for building more complex games or applications using the World of Workflows platform. Give it a try and have fun playing Connect 4!
