Running the example

Note

Before you can run this example, make sure you have:

• Access to one of the supported Chromium web browsers on your computer.

• Git installed to be able to clone a repository from GitHub.

• Node.js and Yarn installed.

Node.js is a JavaScript runtime environment and Yarn is a package manager used in combination with Node.js. You can download Node.js and Yarn on their official websites.

• rustup installed to build the backend.

The frontend needs the Concordium Wallet for Web for interaction. Install the extension for your browser as described here.

Clone this repository.

$git clone --recurse-submodules https://github.com/Concordium/concordium-dapp-examples.git

The minimal steps to run the example are as follows:

• Navigate to the gallery example folder.

$cd ./gallery/

• Run yarn in the gallery folder to install all dependencies.

$yarn

• Run yarn build in the gallery folder to build the frontend.

$yarn build

• Run yarn build-verifier in the gallery folder to build the backend.

$yarn build-verifier

• Run yarn start to run the example.

$yarn start --statement "$(<verifier/config/statement.json)" --names "$(<verifier/config/names.json)"

The statement and names flags must be provided and they specify the values for these static variables. This runs them with the default values found in the gallery/verifier/config folder.

The gallery is then available on http://127.0.0.1:8100, however this can be changed by setting the port flag.
