To clone this repo, use either of the given commands

$ git clone https://github.com/abhigyanghosh30/DApp_Battleship.git $ git clone [email protected]:abhigyanghosh30/DApp_Battleship.git

The app requires 3 things to be installed:

1. React (for frontend)
2. Ganache (to run a test blockchain)
3. Flask and py-solc(backend to deploy contracts and assign opponents automatically)

The instructions here are valid for Linux systems only

To install the frontend and the required modules, go to the folder ./frontend/ and run: $ npm install

To install Ganache, you can download the AppImage from this link Or if you have npm installed, you can install Ganache-CLI by running: $ npm install -g ganache-cli

To install the backend and all the required packages, it is recommended to use a python environment wrapper. Inside the wrapper run $ pip install -r requirements.txt

We are not done yet. We need to install the py-solc compiler also before we can get started. The contract used by this app was built on solc v0.4.24 and is compatible with any solc compiler for v0.4.x. To install this, run: $ python -m solc.install v0.4.25 $ export SOLC_BINARY="$HOME/.py-solc/solc-v0.4.25/bin/solc"

The code is configured for localhost testing out of the box. To deploy it on public servers, you just need to change the server IP addresses.

To run Ganache, simply go to the folder where you have the Ganache AppImage downloaded and run: $ ./ganache-<version>-linux-x86_64.AppImage or run $ ganache-cli --port=8545

To start the python server run

$ cd webapp
$ python main.py

To start the React server run

$ cd frontend
$ npm run start

By default, the app will start at port 3000. Your default browser should open a new tab on http://localhost:3000 after React finishes compiling.

To deploy Flask on a public server, you can follow these tutorials Before deploying, configure the IP addresses to the IP of the corresponding Ethereum networks.

To deploy React on a public server, you can follow this tutorial Before deploying, configure the IP addresses to the IP of the corresponding Ethereum networks. Also change the IP address of the Flask App aptly.
