Project Setup

What We Are Doing:

• Initializing a Node.js/Express project.

• Installing necessary dependencies.

• Preparing the base structure for integration with the Issuer and Verifier.

Why: We need a backend server that:

• Interacts with the Issuer to request credential issuance.

• Interacts with the Verifier to request verification.

• Serves a frontend for user input and QR code display.

Steps:

1. Create a new directory and initialize a Node.js project:

    mkdir -p evdi-tutorial/{src,public} && \
    touch evdi-tutorial/src/{index.js,issuer-routes.js,verifier-routes.js,authorization-routes.js} \
      evdi-tutorial/public/{index.html,dashboard.html} \
      evdi-tutorial/.env
    cd evdi-tutorial
    npm init -y

Project structure:

 evdi-tutorial/
   src/
     index.js
     issuer-routes.js
     verifier-routes.js
     authorization-routes.js
   public/
     index.html
     dashboard.html
   .env

1. Install dependencies:

 npm install express dotenv @empe/verifier-client @empe/identity jsonwebtoken node-fetch

Next, we will deploy an Issuer service via the One-Click Deployment portal.
