Piggy Bank Web Application

Example dApp for showcasing how to integrate with a smart contract on the Concordium blockchain. The application supports integration with the Browser Wallet and with the Mobile Wallets via Wallet Connect.

The project was bootstrapped with Create React App.

Install

Run yarn in the root of the project.

Run

Run the app in development mode with

yarn start

This spins up a server which serves the app on http://localhost:3000.

Linting errors will appear in the console.

Changes to the source code will cause the page to refresh automatically.

Build

Build the app for production using

yarn build

This will drop an optimized and minified bundle in the build folder that is ready to be deployed.

See the section about deployment for more information.

Docker

The project includes a dockerfile for building the app for production and running it in a container. The default build image node:16-slim may be overridden using build arg build_image.

The easiest way to build and run the app is with Docker Compose:

docker-compose up --build

This command will build the app with default settings and deploy it in a HTTPd server container on running on port 8080 (by default).

The Compose spec is parameterized as follows:

  • PIGGYBANK_IMAGE (default: piggybank:test): Image to build and/or start. Remove the --build flag to start an existing image without building it.
  • PIGGYBANK_PORT (default: 8080): Port to run the server on.
