Animo OpenID4VC Playground

License

Tip

Check out the demo at https://openid4vc.animo.id

✨ Hi there!

Welcome to the repository of Animo's OpenID4VC Playground. This interactive playground demonstrates the use of OpenID4VC with different credential formats (such as SD-JWT VCs). This demo is built using Aries Framework Javascript (AFJ). AFJ is a framework written in TypeScript for building decentralized identity services.

🛠️ Usage

Prerequisites

  • NodeJS v18.X.X - Other versions may work, not tested
  • pnpm
  • Git - You probably already have this

🖥 App

Copy the .env.example file to a .env.local file and set the environment variables. This is not needed for development.

cd app
cp .env.example .env
Variable Description
NEXT_PUBLIC_API_URL Used in the frontend application to connect with the backend. Default to http://localhost:3001 for development.

🎛️ Agent

Copy the .env.example file to a .env.local file and set the environment variables. This is not needed for development.

cd agent
cp .env.example .env
Variable Description
AGENT_HOST Used in the backend application for the agent. The url at which the server will be available.
AGENT_WALLET_KEY Used in the backend application for the agent. Should be secure and kept private.

Important

The issuer will use did:web for issuing credentials, but this requires https to be used. When developing locally it is recommend to use ngrok (npx ngrok http 3001) and use that url as the AGENT_HOST variable. Make sure to also set the NEXT_PUBLIC_API_URL variable in the app to the ngrok.

We may add issuance using did:key in development if the host url does not start with https.

Install Dependencies

pnpm install

Development

Open three terminal windows, and then run the following:

npx ngrok http 3001

Copy the https url from the ngrok command and set that as the AGENT_HOST

cd agent
AGENT_HOST=https://30f9-58-136-114-148.ngrok-free.app pnpm dev
cd app
pnpm dev
