How do I connect the app running using Nodejs with the service dependencies running using docker-compose

I am trying to run this repository (https://github.com/energywebfoundation/ssi-hub). I am running the app separately with service dependencies being run in docker-compose. However, my app is not able to connect to the redis service running in the docker-compose file. I get the following error

      throw er; // Unhandled 'error' event
      ^

Error: getaddrinfo ENOTFOUND redis
    at GetAddrInfoReqWrap.onlookup [as oncomplete] (node:dns:71:26)

}

I am using this configuration file to run redis service in docker composer

services:
  postgres:
    image: postgres:12-alpine
    environment:
      POSTGRES_PASSWORD: password
      POSTGRES_USERNAME: postgres
      POSTGRES_DB: dev-test
    networks:
      - main
    ports:
      - 5432:5432
  nats:
    container_name: nats
    image: synadia/nats-server:nightly
    volumes:
      - ./config/:/etc/nats
    command: '-c /etc/nats/nats.conf'
    networks:
      - main
    ports:
      - '4222:4222'
      - '8222:8222'
      - '9222:9222'
  redis:
    container_name: redis
    image: redis:${REDIS_VERSION}
    command: redis-server --requirepass ${REDIS_PASSWORD}
    volumes:
      - $PWD/redis-data:/var/lib/redis
    ports:
      - '6379:6379'
    environment:
      - REDIS_REPLICATION_MODE=master
    networks:
      - main
