Just run yarn !
Proceed with the database configuration.

With docker installed,

1. Verify if the port 5432 is free (kill the process or choose another port)
2. Run the following command to create a Postgres DB image in docker (within3 as database name):
   docker run --name within3 -e POSTGRES_PASSWORD=root -e POSTGRES_DB=within3 -p 5432:5432 -d postgres
3. To populate the database, choose one of the options:
   3.1 Run the following command to import the postgres dump (changing the path):
   docker exec -i within3 /bin/bash -c "PGPASSWORD=root psql --username postgres within3" < /path/to/project/dump.sql
   3.2 Or run the migrations with the following command:
   yarn typeorm migration:run

Open ormconfig.json and change the port, database name or host if necessary.

Run:
yarn run dev

Run:
yarn test

Use Apollo Studio (https://studio.apollographql.com/sandbox/explorer) or some tool to do a GraphQL Query with the following:

query {
  zipCode(zipCode: 20601) {
    zipCode,
    county {
      name
    }
    city {
      name
    }
  }
}

Try with '20605' zipcode to receive a 404 not found response.
Other valid zipcodes are in src/database/data/Zip_Code_Lookup_Table.csv

• Add unit tests and not only e2e.
• Create relationship between Cities and Counties.
• Zipcode validation?
• Docker for the App
