Sudoku helper

A project to help you solve Sudokus. This app does not generate Sudoku grids. You have to fill this grid based on some you have. This version will not tell you if there is a mistake in the grid. Maybe in a future release.

The follonwing instructions require Docker and Docker Compose.

Installation

Downloading the project :

user@host ~$ cd [PATH_WHERE_TO_PUT_THE_PROJECT] # E.g. ~/projects/
user@host projects$ git clone https://github.com/cyrilverloop/sudoku-helper.git
user@host projects$ cd sudoku-helper

Installing the dependencies :

user@host sudoku-helper$ docker compose run --rm app npm i

Configuration

Add the default container configuration :

user@host sudoku-helper$ cp docker-compose.override.yml.dist docker-compose.override.yml

The default port is "3000" and the connection does not use a TLS certificate.

To use a TLS certificate in the dev environment, put the certificate in ./tls/server.crt, the key in ./tls/server.key and use command: ["npm", "run", "dev-tls"] in the ./docker-compose.override.yml.

The ./docker-compose.override.yml file and the ./tls/ directory are ignored by git, you can modify them to your needs.

Running the app

By default, the app will be available in your browser through : http://localhost:3000/

In development

user@host sudoku-helper$ docker compose up -d

Stopping :

user@host sudoku-helper$ docker compose down

Using the app

On the web page, the app displays an empty Sudoku grid. Selecting a square will let you choose its type :

• empty : a square without a value. By default, all squares are empty;
• draft : a multi-value square. To be used when you are unsure of its value;
• answer : a square with your answer;
• filled : a square with the original grid value.

Selecting draft will allow you to choose multiple values, while answer or filled can have only one. Selecting empty will erase any data in the square.

A square can be deselected by clicking / touching it again.
