full-stack web app for checking, validating and solving a Sudoku puzzle. This application validates the input puzzle string but also assesses the correctness of number placements. In addition, it also provides solutions to valid puzzles.\n\n## Technologies Used\n- **Client Side:**\n    - HTML: Provides the structure of the web pages.\n    - CSS: Adds styling and responsive design to the user interface.\n    - Vanilla JavaScript: Implements the client-side functionality for unit conversion.\n\n- **Server Side:**\n    - Node.js: Provides the runtime environment for the server.\n    - Express.js: A web application framework for handling routes and requests on the server.\n\n- **Testing:**\n    - Mocha: A testing framework for writing unit tests.\n    - Chai: An assertion library used in conjunction with Mocha for making test assertions.\n\n## Features\n- Checks if a given number and placement is valid based on the given board\n- Solves the puzzle given a valid puzzle string\n\n## Running the application\nTo run the express application, do follow the following steps\n\n1. Clone the repo:\n   ```git\n   git clone git@github.com:mrarvind90/fcc-sudoku-solver.git\n   ```\n2. Navigate to the repository:\n    ```shell\n    cd \u003crepository_directory\u003e\n    ```\n   Change \u003crepository_directory\u003e to the name of the cloned directory.\n3. Install Dependencies:\n    ```shell\n    npm install\n    ```\n   This command will install all the necessary dependencies for the application.\n4. Configure Environment Variables: Rename the .env.sample file in your project directory to .env and update it with the\n   relevant credentials:\n    ```shell\n     cp .env.example .env\n    ```\n5. Choose Your Run Mode:\u003cbr\u003e\n    - Development Mode (with automatic code reload):\u003cbr\u003e To run the application in watch mode, enabling seamless source\n      code changes without manual server restarts, use the following command:\n    ```shell\n     npm run dev\n    ```\n    - Standard Server Mode:\u003cbr\u003e If you prefer to simply run the server without automatic code reloading, you can use the\n      following command:\n    ```shell\n     npm run start\n    ```\n6. Running the tests\n    - You can run unit tests for the application using Mocha and Chai. To run the tests, use the following command:\n    ```bash\n    npm run test\n    ```\n\n## Future Improvements\nWhile developing this project, there are several areas I plan to focus on for enhancements and refinements\nwhich can be found on [GitHub](https://github.com/mrarvind90/fcc-sudoku-solver/issues).\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmrarvind90%2Ffcc-sudoku-solver","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmrarvind90%2Ffcc-sudoku-solver","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmrarvind90%2Ffcc-sudoku-solver/lists"}
