Verity Sample Web App

This is a sample web app demonstrating how Verity REST API can be used for SSI flows like connection establishment, credential issuance, proof exchange or committed answer.

Launching the application Locally

Requirements:

• You have received Domain DID and REST API key from Evernym
• You have NodeJs v12 installed
• You have ngrok installed (https://ngrok.com/).

NOTE: Ngrok is used to create a public webhook URL which will forward response messages from Verity Application Server to the web app. If you have capabilities to start the application on a public IP address then you don't need ngrok]

To try out the application follow these steps:

• In a separate terminal window start ngrok for port 3000 and leave it running:

ngrok http 3000

• Install required NodeJs packages:

npm install

• Start the web app

node app.js

• Fill in prompts for input parameters:

Verity Application URL: https://vas.pps.evernym.com
Domain DID: <copy domain DID received from Evernym>
X-API-KEY: <copy API key received from Evernym>
Webhook URL: <copy public URL address of the Ngrok forwarding tunnel to your local port 3000>

The application will be available on http://localhost:3000

Launching the application using Docker

Requirements:

• You have received Domain DID and REST API key from Evernym
• You have Docker installed

To start the app follow these steps:

• Fill in values for VERITY_URL, DOMAIN_DID and X_API_KEY (you should have received these inputs from Evernym) into .env file in the current folder. A properly filled .env file should have this format:

VERITY_URL=https://vas.pps.evernym.com
DOMAIN_DID=W1TWvjCTGzHGEgbzdh5U4b
X_API_KEY=AkdrCwUhNXiQi3zgwKw2KhR6muAX1Q18phP4cfuMtvq4:4cBQC9EsbMa9T96KA4noZwLJQuVcd6KBwaqFhRqZQKFWT45VEm3jbPCm8S6bqhwh3UKEKAPkHeLz9Gb1d1YE1dW

NOTE: These are just sample reference values. These values will NOT work if left unchanged. You should specify DOMAIN_DID and X_API_KEY that you received from Evernym

• Create a docker image with pre-installed requirements. Run this command from the current folder:

docker build -t demo-web-app .

Start a Docker container:

docker run -p 3000:3000 --env-file .env -it demo-web-app

The application will be available on http://localhost:3000
