If you're running as separate modules not in a containerized context, create a .env File with the following variables specific to your setup:

CONTROLLERPORT=3100
AGENTADDRESS='http://AGENT_IP_ADDRESS:8150' (the default agent address is localhost)
WEB_ROOT=https://localhost_or_ip_address_or_domain:port_number_if_necessary/
JWT_SECRET=yoursecrethere (32 alpha-numeric digits, e.g. GGgNz2CVwxBJjhVzHmuKPV3bEJMdViKP)
SESSION_SECRET=yoursecrethere (32 alpha-numeric digits, e.g. y5YSfodHhp6QkbG3IxaqlzcFQXUlZquh)

If you need to reset your ecryption key (the raw key which is used by the algorithm and iv) for the SMTP password encrypyion, copy and run these commands to generate one. Then replace the old key with the new one ( e.g. ISSUER_ENC_KEY=40222988217e8dd592fc84fbf6ca20d7)

const crypto = require('crypto')
const enc_key = crypto.randomBytes(16).toString('hex')
console.log(enc_key)

Add the following line to your ACA-Py Agent startup.sh file:

--webhook-url "$WEBHOOK_ADDRESS" \

Add the controller ip-address (default localhost) and port (default port 3100) in your agent YML file for each agent the following line:

WEBHOOK_ADDRESS: http://CONTROLLER_IP_ADDRESS:CONTROLLER_PORT/api/controller-webhook

Run the following command to install the needed dependencies

npm install

Once the controller, agent, and database are all running, you will need to run a one-time startup script, which will also need to be ran everytime the agent and database are reset. This script will set up a public DID for you, provide the TAA for acceptance, and create a credential definition.

/bin/bash ./scripts/startupScript.sh

• Installing this app and dependencies (including cloud agent, network, etc.)
• OS requirements, etc.
• Quick test to make sure everything is working

Upon installation, run

npm run dev

/bin/bash ./scripts/startupScript.sh

In the project directory, you can run the following command to build the app for production to the build folder:
