Warp D.R.E.

A Delegated Resolution Environment for Warp Contracts. Docs are available here.

Update mode

DRE can run in two different modes. Each of them listens on gateways notification and registers new contracts, but upcoming new interactions are handled differently.

Poll

Node fetches interactions directly from gateway in time intervals. Interaction are grouped and executed sequentially. This is the default mode.

Subscription

Node listens on new interactions events and evaluates contracts immediately after every interaction. This offers a faster contract evaluation and serves the latest contract state

Update mode can be set up using env config UPDATE_MODE='poll' or UPDATE_MODE='subscription'

Deployment

1. Database

1. Local env

1. npm run run-docker:local
2. Confirm that database is running locally

docker ps -a

# should display something similar to:
CONTAINER ID   IMAGE              COMMAND                  CREATED          STATUS          PORTS                      NAMES
f240114e69a0   postgres:14        "docker-entrypoint.s…"   11 minutes ago   Up 11 minutes   0.0.0.0:21726->5432/tcp    dre-postgres
c3ee9a099cda   redis:7.0-alpine   "docker-entrypoint.s…"   11 minutes ago   Up 11 minutes   127.0.0.1:6379->6379/tcp   warp-dre-node-bullmq-1

3. Run database initialization script: npm run db-setup:local (the default password for user postgres is postgres)
