Crash Game

This is the backend code for Crash Game.

Usage

Step 1: Download repo and install modules

git clone https://github.com/wholespace214/crash-game-backend
cd crash-game-backend
npm install

Step 2: Start the docker containers needed

docker-compose -f docker/docker-compose.yml up -d

Step 3: Configure the mongo container for replication

docker exec -it mongodb-wall bash

mongo -u wallfair -p wallfair admin
use wallfair

rs.initiate( {
   _id : "rs0",
   members: [
      { _id: 0, host: "localhost:27017" },
   ]
});

Step 4: Run the postgresql config

docker exec -it docker_postgres_1 bash
psql -U postgres testdb

CREATE TABLE IF NOT EXISTS token_transactions (ID SERIAL PRIMARY KEY, sender varchar(255) not null, receiver varchar(255) not null, amount bigint not null, symbol varchar(255) not null, trx_timestamp timestamp not null);
CREATE TABLE IF NOT EXISTS token_balances (owner varchar(255) not null, balance bigint not null, symbol varchar(255) not null, last_update timestamp not null, PRIMARY KEY(owner, symbol));
CREATE TABLE IF NOT EXISTS bet_reports (bet_id varchar(255) not null PRIMARY KEY, reporter varchar(255) not null, outcome smallint not null, report_timestamp timestamp not null);
CREATE TABLE IF NOT EXISTS amm_interactions (ID SERIAL PRIMARY KEY, buyer varchar(255) NOT NULL, bet varchar(255) NOT NULL, outcome smallint NOT NULL, direction varchar(10) NOT NULL, investmentAmount bigint NOT NULL, feeAmount bigint NOT NULL, outcomeTokensBought bigint NOT NULL, trx_timestamp timestamp NOT NULL);
CREATE TABLE IF NOT EXISTS casino_trades (ID SERIAL PRIMARY KEY, userId varchar(255) NOT NULL, crashFactor decimal NOT NULL, stakedAmount bigint NOT NULL, state smallint NOT NULL, gameId varchar(255), created_at TIMESTAMP WITH TIME ZONE DEFAULT CURRENT_TIMESTAMP);

Step 5: Create a .env file (see .env.example) and start the server with:

# copy .env file from email
npm run start
