launching a containerized database for testing purposes

First you need to Install Docker

then run this command to run a postgres container which maps port 5432 to localhost:5432

docker run --name pg -p 5432:5432 -d postgres

then this command will give you a psql shell with the appropriate user:

docker exec -it pg psql postgres postgres

users Package

after database is created, run this command to create a users table

CREATE TABLE users (
	id       	  SERIAL PRIMARY KEY NOT NULL,
	firstName     	  VARCHAR(255) NOT NULL,
	LastName 	  VARCHAR(255) NOT NULL,
	email		  VARCHAR(255) NOT NULL,
        createdAt         TIMESTAMP NOT NULL DEFAULT NOW(),
        updatedAt         TIMESTAMP NOT NULL DEFAULT NOW()
);

./main

this will make available the following endpoints:

lbtc package

first create this table

CREATE TABLE btcoffers (
  ID SERIAL PRIMARY KEY NOT NULL,
  Title VARCHAR(255) NOT NULL,
	Trader VARCHAR(255) NOT NULL,
	Bank VARCHAR(255) NOT NULL,
	Currency VARCHAR(255) NOT NULL,
	Reputation SMALLINT,
	Price FLOAT,
	Min FLOAT,
	Max FLOAT,
	Index SMALLINT NOT NULL,
  CreatedAt         TIMESTAMP NOT NULL DEFAULT NOW(),
  UpdatedAt         TIMESTAMP NOT NULL DEFAULT NOW()
);
