contractupdate

concordium-dapp-contractupdate

Sample dApp that demonstrates how the libraries may be used to implement a robust dApp. It allows the user to invoke any method on any smart contract on the chain either via the Browser Wallet or WalletConnect.

Install

Run

yarn

to install dependencies.

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 that by default listens to port 8080.

The Compose spec is parameterized as follows:

• CONTRACTUPDATE_IMAGE (default: concordium-dapp-contractupdate:test): Image to build and/or start. Remove the --build flag to start an existing image without building it.
• CONTRACTUPDATE_PORT (default: 8080): Port to run the server on.

Note that the Dockerfile doesn't build using the repository's yarn.lock file as it resides in the repository root due to this being a yarn workspace.
